Every year, world leaders gather to find ways of limiting global warming. The latest of these ‘COP’ meetings, COP30, is in Belém, Brazil from 10 to 20 November 2025. COP stands for ‘Conference of the Parties’, the decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC).
Perhaps the best-known of these meetings was in Paris in 2015. This resulted in the Paris Agreement. This is a legally-binding international treaty to limit global warming to well below 2°C and preferably to 1.5°C above pre-industrial levels. This would involve reducing greenhouse gas emissions and/or taking carbon absorbing measures. All UN countries except for Iran, Libya and Yemen are signatories to the agreement.
However, on coming to office in January 2025, President Trump announced that the USA will withdraw from the agreement in January 2026. Instead, he would prioritise fossil fuel production, under the mantra, ‘drill, baby, drill’. Previously he had claimed that global warming is a hoax concocted by China designed to undermine the competitive power of the USA.
Progress in reducing emissions and mitigating climate change
Since 2020, each country has been required to submit its own emissions-reduction targets, known as ‘nationally determined contributions’ (NDCs), and the actions it will take to meet them. Every five years each country must submit a new NDC more ambitious than the last. New NDCs are due this year. As of 12 November, 112 of the 197 countries had submitted a new NDC (including the USA, China, the EU and the UK). These 112 countries account for around 71 per cent of global emissions.
Implementing all new NDCs would reduce global CO2 emissions by between 15 and 25 per cent from current levels by 2035. But this would merely reduce global warming to around 2.6°C above pre-industrial levels. Approximately 35 per cent emissions reductions by 2035 would be required to restrict global warming to 2°C and 55 per cent to restrict it to 1.5°C.
But implementing the Paris Agreement has still had a high degree of success. Without the action taken and being taken over the past 10 years, it is predicted that global temperatures by 2050 would rise by 3–3.5°C.
Rich countries are expected to provide finance to low-income countries. This is required to help such countries adopt green technologies and to adapt to the harmful effects of climate change (e.g. through irrigation schemes and flood defences). At COP29 in Azerbaijan, the ‘Baku Finance Goal’ was agreed. This is an agreement to provide climate finance of $1.3 trillion per year by 2035 to developing countries from all public and private sources.
The subsequent ‘Baku to Belém Roadmap’ provides a set of suggested actions for governments, financial institutions and the private sector to bridge the gap between current climate finance flows and the $1.3 trillion agreed to meet global climate goals. The roadmap is a central focus of the COP30 conference in Belém, with discussions between countries on how to translate the Baku finance goal into concrete, tangible actions and integrate it into formal decisions.
The role of Donald Trump
As well as announcing that the USA will withdraw from the Paris Agreement in January 2026, since coming to office in 2025, President Trump has given billions of dollars of tax cuts to fossil fuel firms and allowed drilling for oil and gas on federal lands. At the same time, he has described renewable energy as ‘a joke’ that will bankrupt countries and has slashed subsidies and tax breaks for solar and wind power, withdrawn permits for wind and solar farms, and cut funding for green energy research.
He wants the USA to be world leader in fossil fuel energy, calling on governments to buy US oil and gas, threatening some countries with tariffs if they do not. Already, Japan, South Korea and several European countries have agreed to buy huge quantities of US oil and liquefied natural gas (LNG). A worry is that other similarly inclined governments, such as Argentina, may roll back on their commitments to a green transition and instead boost their fossil fuel industries.
This gives added urgency to the Belém talks. It is crucial for the rest of the world to stick together in pushing ahead to combat global warming and in adopting and sticking to tough NDCs. It is also crucial for rich countries to support dlow-income countries in adopting climate-friendly investment and in measures to mitigate the effects of global warming.
The economics of climate change
Climate change is directly caused by market failures. One of the most important of these is that the atmosphere is a common resource: it is not privately owned; it is a global ‘commons’. Individuals and firms use it at a zero price. If the price of any good or service to the user is zero, there is no incentive to economise on its use. Thus for the emitter there are no private costs of using the atmosphere in this way as a ‘dump’ for their emissions and, in a free market, no incentive to reduce the climate costs.
And yet when firms emit greenhouse gases into the atmosphere there are costs to other people. To the extent that they contribute to global warming, part of these costs will be borne by the residents of that country; but a large part will be borne by inhabitants of other countries.
These climate costs are external costs to the firm and are illustrated in the figure. It shows an industry that emits CO2. To keep the analysis simple, assume that it is a perfectly competitive industry with demand and supply given by curves D and S, which are equal to the marginal private benefits (MPB) and marginal private costs (MPC), respectively. There are no externalities on the demand side and hence MPB equals the marginal social cost (MSB). Market equilibrium is at point a, with output at Qpc and price at Ppc. (Click here for a PowerPoint.)
Assume that the emissions create a marginal cost to society equal to MECc. Assume that the MEC increases as output and total emissions increase. The MECc line is thus upward sloping. At the market price of Qpc, these external climate costs are equal to the purple vertical line. When these external climate costs are added to private costs, this gives a marginal social cost given by MSC = MPC + MECc. The gives a socially optimal level of output of the product of Q* at a price of P*, with the optimum point of c.
In other words, other things being equal, the free market overproduces products with climate externalities. If the output is to be reduced to the social optimum of Q*, then the government will need to take measures such as those advocated in the Paris Agreement. These could include imposing taxes on products, such as electricity generated by fossil fuels, or on the emissions themselves. Or green alternatives, such as wind power, could be subsidised.
Alternatively, regulations could be used to cap the production of products creating emissions, or caps on the emissions themselves could be imposed. Emissions permits could be issued or auctioned. Only firms in possession of the permits would be allowed to emit and the permits would cap emissions below free-market levels. These permits could be traded under a cap-and-trade scheme, such as the EU’s Emissions Trading Scheme. Again, such schemes are advocated under the Paris Agreement.
COP30 and progress in tackling climate change
The USA is not attending COP30 in Brazil. Nor is the Chinese leader, Xi Jinping. However, there are growing opportunities for translating aims into practical policies for specific sectors, such as energy, transport and carbon-intensive industries. These policies may require some degree of government action – taxes, subsidies or regulation – to internalise climate externalities. But increasingly, green alternatives are becoming economically viable without subsidies or with just initial government funding to ‘crowd in’ private investment, which will then attract further private capital as external economies of scale kick in. Increasingly investors will find profitable opportunities in climate-friendly projects.
At the same time, while the USA is moving away from climate-friendly investment (as least for the term of the Trump Presidency), China is moving in the opposite direction, with massive investment in solar panels, wind turbines, EVs and batteries – investment that is bringing down their cost and thereby encouraging their adoption around the world. Such technologies create huge opportunities for low-income countries to provide affordable energy and to create local jobs, both skilled and unskilled. It also helps them achieve much greater energy security by reducing their reliance on fossil fuel imports
Chinese advances in green technology are also providing a stimulus to other countries to invest in renewable industries to prevent Chinese dominance. The danger, however, of Chinese dominance in the renewable sector in high-income countries is that it may encourage them to impose tariffs on Chinese imports of EVs, solar panels, etc. to protect their own industries.
But despite the growing opportunities for profitable adoption of green technologies without government support, there is still much that governments need to do to encourage the process. COP meetings are an important forum for discussing such policies and holding governments to account for meeting or not meeting their targets.

The gold market has become one of the most talked-about commodity markets in 2025, with prices reaching record highs. This is largely due to increased demand from investors, who see gold as a ‘safe haven’ during times of economic and political uncertainty. Central banks are also buying more gold as a way to reduce their reliance on currencies like the US dollar. With many analysts predicting prices could reach over $4000 per ounce in the next year, the gold market is showcasing how supply and demand, confidence, and global events can all influence a commodity market.
The commodities market is where basic agricultural products, raw materials and metals, such as gold, are bought and sold, often in large quantities and across global exchanges. Commodities are typically traded either in their physical form (like gold bars) at current market prices (spot prices) or through financial contracts, where investors buy or sell in futures markets. These are where a price is agreed today to buy or sell on a specific future date.
As with other commodities, the price of gold is determined by supply and demand. Demand for gold typically rises during times of economic uncertainty as investors want a safer store of value. This results in an increase in its price. Supply and demand, and hence price, also respond to other factors, including interest rates, currency movements, economic growth and growth prospects, and geopolitical events.
Record high prices
This year, the gold market has seen a remarkable rally, with the price of gold hitting a record high. Demand for the precious metal has resulted in spot prices surging over 35% to date (see the chart: click here for a PowerPoint). Rising prices earlier this year have been attributed to the US President, Donald Trump, announcing wide-ranging tariffs which have upset global trade. On 2 September, the spot gold price hit $3508.50 per ounce, continuing its upwards trend.
The price has also been lifted by expectations that the Federal Reserve (the US central bank) will cut its key interest rate, making gold an even more attractive prospect for investors. If the Federal Reserve cuts interest rates, the price of gold usually increases. This is because gold does not pay any interest or yield, so when interest rates are high, investors can earn better returns from alternatives, such as savings accounts or bonds. However, when interest rates fall, those returns become less attractive, making gold relatively more appealing.
Lower interest rates also tend to weaken the US dollar, which makes gold cheaper for foreign buyers, increasing global demand. Since gold is priced in dollars, a weaker dollar usually leads to higher gold prices.
Additionally, interest rate cuts are often a response to economic problems or uncertainty. As gold is viewed as a safer asset for investors during times of economic uncertainty, investors will typically increase their demand.
Unlike the market for currencies or shares, gold doesn’t rely on the performance of a government or company. This makes it attractive when people are worried about things like inflation, recession, war or stock market crashes. Gold is thus seen as a ‘safe haven’.
Gold and the Federal Reserve
The rise in the price of gold by more than a third this year can be linked to the US election last year, according to the director of research at BullionVault (see the BBC article below). Attitudes of the Trump administration towards the Federal Reserve have created concerns among investors. Fears that the US administration could erode the independence of the world’s most important central bank have fuelled the latest flows into the metal, which is traditionally viewed as a hedge against inflation.
According to the BBC article, Derren Nathan from Hargreaves Lansdown claims that it is Trump’s ‘attempts to undermine the independence of the Federal Reserve Bank’ that were ‘driving renewed interest in safe haven assets, including gold’. Investors are concerned that a politicised Fed would be more inclined to cut interest rates than would otherwise be the case, sending long-term inflation expectations higher.
This could lead to fears that future interest rates would then be pushed higher. This would increase the yields on longer-term government bonds by pushing down their price, as investors demand higher compensation for the increased risk of higher future interest rates reducing the value of their fixed-rate investments. This would force the US Treasury to pay higher interest on new bonds, making it more expensive to service US government debt.
Expected price rises for 2026
As we saw above, it is predicted that the price of gold will rise to $4000 per ounce next year. However, if the market sees investors move away from dollar assets, such as US Treasuries, the price increases would be even higher. Daan Struyven, co-head of global commodities research at Goldman Sachs explains ‘If 1 per cent of the privately owned US Treasury market were to flow to gold, the gold price would rise to nearly $5000 per troy ounce’ (see Financial Times article below).
If the Federal Reserve does come under political pressure, it could affect the stability of the US economy and beyond. When gold prices rise sharply, demand usually falls in countries like China and India, which are the world’s largest buyers of gold jewellery. However, in 2025, this trend has changed. Instead of reducing their gold purchases, people in these countries have started buying investment gold, such as bars and coins, showing a shift in consumer behaviour from jewellery to investment assets.
At the same time, global events are also influencing the gold market. Suki Cooper, a metals analyst at Standard Chartered, said that events like Russia’s invasion of Ukraine have added to political uncertainty, which tends to increase demand for gold as a safe-haven asset. She also highlighted how changes in international trade policies have disrupted supply chains and contributed to higher inflation, both of which have made gold more attractive to investors. Additionally, a weaker US dollar earlier in the year made gold cheaper for buyers using other currencies, which boosted global demand even further.
Conclusion
Although the gold market is expected to remain strong over the next six months, some uncertainty remains. Many analysts predict that gold prices will stay high or even increase further, especially if interest rates in the US are cut as expected. Continued global instability, is also likely to keep demand for gold as a safe haven high. At the same time, if inflation stays elevated or trade disruptions continue, more investors may turn to gold to protect their wealth.
However, if economic conditions stabilise or interest rates rise again, gold demand could fall slightly, leading to a potential dip in prices. Overall, the outlook for gold remains positive, but sensitive to changes in global economic and political events.

In a blog in October 2024, we looked at global uncertainty and how it can be captured in a World Uncertainty Index. The blog stated that ‘We continue to live through incredibly turbulent times. In the past decade or so we have experienced a global financial crisis, a global health emergency, seen the UK’s departure from the European Union, and witnessed increasing levels of geopolitical tension and conflict’.
Since then, Donald Trump has been elected for a second term and has introduced sweeping tariffs. What is more, the tariffs announced on so-called ‘Liberation Day‘ have not remained fixed, but have fluctuated with negotiations and threatened retaliation. The resulting uncertainty makes it very hard for businesses to plan and many have been unwilling to commit to investment decisions. The uncertainty has been compounded by geopolitical events, such as the continuing war in Ukraine, the war in Gaza and the June 13 Israeli attack on Iran.
The World Uncertainty Index (WUI) tracks uncertainty around the world by applying a form of text mining known as ‘term frequency’ to the country reports produced by the Economist Intelligence Unit (EIU). The words searched for are ‘uncertain’, ‘uncertainty’ and ‘uncertainties’ and the number of times they occur as percentage of the total words is recorded. To produce the WUI this figure is then multiplied by 1m. A higher WUI number indicates a greater level of uncertainty.
The monthly global average WUI is shown in Chart 1 (click here for a PowerPoint). It is based on 71 countries. Since 2008 the WUI has averaged a little over 23 000: i.e. 2.3 per cent of the text in EIU reports contains the word ‘uncertainty’ or a close variant. In May 2025, it was almost 79 000 – the highest since the index was first complied in 2008. The previous highest was in March 2020, at the start of the COVID-19 outbreak, when the index rose to just over 56 000.
The second chart shows the World Trade Uncertainty Index (WTUI), published on the same site as the WUI (click here for a PowerPoint). The method adopted in its construction therefore mirrors that for the WUI but counts the number of times in EIU country reports ‘uncertainty’ is mentioned within proximity to a word related to trade, such as ‘protectionism’, ‘NAFTA’, ‘tariff’, ‘trade’, ‘UNCTAD’ or ‘WTO.’
The chart shows that in May 2025, the WTUI had risen to just over 23 000 – the second highest since December 2019, when President Trump imposed a new round of tariffs on Chinese imports and announced that he would restore steel tariffs on Brazil and Argentina. Since 2008, the WTUI has averaged just 2228.
It remains to be seen whether more stability in trade relations and geopolitics will allow WUI and WUTI to decline once more, or whether greater instability will simply lead to greater uncertainty, with damaging consequences for investment and also for consumption and employment.

The UK signed three trade deals in May – one with the USA, one with India and one with the EU. It is hoped by the government that these trade deals will provide a welcome boost to the UK economy.
The deal with the USA reduced tariffs on UK car exports to the USA from 27.5% to 10%, and on steel and aluminium exports from 25% to 0%. Pharmaceutical exports would also get more favourable treatment and there would be ‘reciprocal market access on beef’ (but with no lowering of food standards). Nevertheless, President Trump’s baseline tariff of 10% on most goods remains, as with other countries. However, a ruling by the US Court of International Trade has found that the Trump’s use of emergency powers to justify the sweeping use of tariffs is wrong. The Trump administration is appealing against the ruling and until the appeal is heard, the tariffs have been reinstated. Also, on May 30, the Trump administration announced that tariffs on steel and aluminium imports would rise from 25% to 50%. It remained to be seen whether this would affect the deal to reduce the rate to zero for British steel and aluminium imports.
The deal with India involves a reduction in tariffs on UK exports – some to zero – and simplified trade rules, faster customs clearance, less paperwork and the freedom for UK businesses to provide telecommunications and construction services. In return, tariffs will be reduced to zero on 99% of Indian exports to the UK. The UK government estimates that deal will result in trade between the two countries increasing by over 30%, with the UK’s GDP expanding by around 0.1 percentage points per year.
UK-EU trade
Perhaps the most significant new trade deal, however, is with the EU. This is a major advance on the current post-Brexit Trade and Cooperation Agreement (TCA). Under the TCA, there are no tariffs or quotas on UK goods exports to the EU or EU goods exports to the UK. However, to ensure that it is EU and UK business that benefits from these ‘trade preferences’, firms must show that their products fulfil ‘rules of origin’ requirements.
Under rules of origin requirements, when a good is imported into the UK from outside the EU and then has value added to it by processing, packaging, cleaning, remixing, preserving, refashioning, etc., it can only count as a UK good if sufficient value or weight is added. The proportions vary by product, but generally goods must have approximately 50 per cent UK content (or 80 per cent of the weight of foodstuffs) to qualify for tariff-free access to the EU. As a result, many goods exported to the EU with a proportion of imported components face tariffs.
Also, the TCA does not include free trade in services. The UK is a major exporter of services, including legal, financial, accounting, IT and engineering. It has a positive trade in services balance with the EU, unlike its negative trade in goods balance. Although some of the barriers which apply to other non-EU countries have been reduced for the UK in the TCA, UK service providers still face barriers which impose costs. For example, some EU countries limit the time that businesspeople providing services can stay in their countries to six months in any twelve. Also, since Brexit, UK artists and musicians have faced restrictions when touring and working in the EU. They can only work up to 90 out of every 180 days. This causes problems for longer tours and for musicians and crew who work in multiple bands or orchestras.
Perhaps the greatest barrier to trade under the TCA has been the large range of non-tariff measures (NTMs), such as customs checks, rules-of-origin and other paperwork, meeting various regulations and standards, and sanitary and phytosanitary checks on foodstuffs, plants and animals. Both the OBR and the Bank of England estimate that these post-Brexit trade restrictions are reducing UK GDP by around 4% and will continue to do so unless trade with the EU becomes freer.
The new UK-EU trade deal
The deal struck in mid-May reduces many of the administrative barriers to trade. Perhaps the most significant are the border checks on food, animal and plant shipments to and from the EU. Many of these checks will be scrapped. The new sanitary and phytosanitary (SPS) agreement allows many UK food products to be exported that previously were banned or proved too administratively costly. To achieve this free movement, the UK will generally follow EU standards, or similar standards so as to avoids harming EU trade. UK food exporters have generally welcomed the deal.
British steel exports to the EU will be protected from new EU rules and tariffs. This should save UK steel some £25m per year. Also, the EU has agreed to recognise UK carbon emissions caps, meaning that UK exports to the EU will avoid around £800m of carbon border taxes.
The post-Brexit fishing deal between the UK and EU, which saw a reduction of 25% in EU fishing quotas in UK waters, will be extended for another 12 years. Many UK fishers, however, had hoped for scrapping EU access to UK waters. The deal also allows various sea foods, including certain shellfish, to be exported to the EU for the first time since Brexit.
Other elements of the deal include a new security and defence partnership, the use of e-gates for UK travellers to the EU and an agreement to work towards a young person’s mobility scheme, allowing young people from the UK/EU to work and travel freely in the EU/UK again for a period of time.
The elements of the deal concerned with trade represent freer trade, but not totally free trade. The UK is not rejoining the customs union or single market. Nevertheless, strong supporters of Brexit have criticised the deal as a movement towards greater alignment of standards and thus a dilution of UK sovereignty. Supporters of greater alignment, on the other hand, argue that the deal does not go far enough and that even freer trade and less red tape would bring greater benefits to the UK.

In a 1987 address to the US nation, Republican President Ronald Reagan discussed the question of tariffs. His message was clear.
You see, at first, when someone says, ‘Let’s impose tariffs on foreign imports,’ it looks like they’re doing the patriotic thing by protecting American products and jobs. And sometimes for a short while it works – but only for a short time. What eventually occurs is:
First, homegrown industries start relying on government protection in the form of high tariffs. They stop competing and stop making the innovative management and technological changes they need to succeed in world markets.
And then, while all this is going on, something even worse occurs: high tariffs inevitably lead to retaliation by foreign countries and the triggering of fierce trade wars. The result is more and more tariffs, higher and higher trade barriers, and less and less competition. So, soon, because of the prices made artificially high by tariffs that subsidise inefficiency and poor management, people stop buying.
Then the worst happens: markets shrink and collapse; businesses and industries shut down; and millions of people lose their jobs.
The memory of all this occurring back in the thirties made me determined when I came to Washington to spare the American people the protectionist legislation that destroys prosperity.
Now, it hasn’t always been easy. There are those in this Congress, just as there were back in the ’30s, who want to go for the quick political advantage, who will risk America’s prosperity for the sake of a short-term appeal to some special interest group, who forget that more than five million American jobs are directly tied to the foreign export business and additional millions are tied to imports.
For those of us who lived through the Great Depression, the memory of the suffering it caused is deep and searing. And today, many economic analysts and historians argue that high tariff legislation, passed back in that period called the Smoot-Hawley Tariff, greatly deepened the Depression and prevented economic recovery.
He returned to the topic of tariffs in November 1988, when he reflected on the benefits of free and fair trade and the dangers of protectionism.
Here in America, as we reflect on the many things we have to be grateful for, we should take a moment to recognize that one of the key factors behind our nation’s great prosperity is the open trade policy that allows the American people to freely exchange goods and services with free people around the world. The freedom to trade is not a new issue for America.
In 1776 our Founding Fathers signed the Declaration of Independence, charging the British with a number of offenses, among them, and I quote, ‘cutting off our trade with all parts of the world’.
And that same year, a Scottish economist named Adam Smith launched another revolution with a book entitled ‘The Wealth of Nations’, which exposed for all time the folly of protectionism. Over the past 200 years, not only has the argument against tariffs and trade barriers won nearly universal agreement among economists but it has also proven itself in the real world, where we have seen free-trading nations prosper while protectionist countries fall behind.
America’s most recent experiment with protectionism was a disaster for the working men and women of this country. When Congress passed the Smoot-Hawley tariff in 1930, we were told that it would protect America from foreign competition and save jobs in this country – the same line we hear today. The actual result was the Great Depression, the worst economic catastrophe in our history; one out of four Americans were thrown out of work. Two years later, when I cast my first ballot for President, I voted for Franklin Delano Roosevelt, who opposed protectionism and called for the repeal of that disastrous tariff.
Ever since that time, the American people have stayed true to our heritage by rejecting the siren song of protectionism. In recent years, the trade deficit led some misguided politicians to call for protectionism, warning that otherwise we would lose jobs. But they were wrong again. In fact, the United States not only didn’t lose jobs, we created more jobs than all the countries of Western Europe, Canada, and Japan combined. The record is clear that when America’s total trade has increased, American jobs have also increased. And when our total trade has declined, so have the number of jobs.
Part of the difficulty in accepting the good news about trade is in our words. We too often talk about trade while using the vocabulary of war. In war, for one side to win, the other must lose. But commerce is not warfare. Trade is an economic alliance that benefits both countries. There are no losers, only winners. And trade helps strengthen the free world.
Yet today protectionism is being used by some American politicians as a cheap form of nationalism, a fig leaf for those unwilling to maintain America’s military strength and who lack the resolve to stand up to real enemies – countries that would use violence against us or our allies. Our peaceful trading partners are not our enemies; they are our allies.
We should beware of the demagogs who are ready to declare a trade war against our friends – weakening our economy, our national security, and the entire free world – all while cynically waving the American flag. The expansion of the international economy is not a foreign invasion; it is an American triumph, one we worked hard to achieve, and something central to our vision of a peaceful and prosperous world of freedom.
After the Second World War, America led the way to dismantle trade barriers and create a world trading system that set the stage for decades of unparalleled economic growth. And in one week, when important multilateral trade talks are held in Montreal, we will be in the forefront of efforts to improve this system. We want to open more markets for our products, to see to it that all nations play by the rules, and to seek improvement in such areas as dispute resolution and agriculture. We also want to bring the benefits of free trade to new areas, including services, investment, and the protection of intellectual property. Our negotiators will be working hard for all of us.
Yes, back in 1776, our Founding Fathers believed that free trade was worth fighting for. And we can celebrate their victory because today trade is at the core of the alliance that secure the peace and guarantee our freedom; it is the source of our prosperity and the path to an even brighter future for America.
