Economic growth is closely linked to investment. In the short term, there is a demand-side effect: higher investment, by increasing aggregate demand, creates a multiplier effect. GDP rises and unemployment falls. Over the longer term, higher net investment causes a supply-side effect: industrial capacity and potential output rise. This will be from both the greater quantity of capital and, if new investment incorporates superior technology, from a greater productivity of capital.

One of the biggest determinants of investment is certainty about the future: certainty allows businesses to plan investment. Uncertainty, by contrast, is likely to dampen investment. Investment is for future output and if the future is unknown, why undertake costly investment? After all, the cost of investment is generally recouped over several months or year, not immediately. Uncertainty thus increases the risks of investment.

There is currently great uncertainty in the USA and its trading partners. The frequent changes in policy by President Trump are causing a fall in confidence and consequently a fall in investment. The past few weeks have seen large cuts in US government expenditure as his administration seeks to dismantle the current structure of government. The businesses supplying federal agencies thus face great uncertainty about future contracts. Laid-off workers will be forced to cut their spending, which will have knock-on effect on business, who will cut employment and investment as the multiplier and accelerator work through.

There are also worries that the economic chaos caused by President Trump’s frequent policy changes will cause inflation to rise. Higher inflation will prompt the Federal Reserve to raise interest rates. This, in turn, will increase the cost of borrowing for investment.

Tariff uncertainty

Perhaps the biggest uncertainty for business concerns the imposition of tariffs. Many US businesses rely on imports of raw materials, components, equipment, etc. Imposing tariffs on imports raises business costs. But this will vary from firm to firm, depending on the proportion of their inputs that are imported. And even when the inputs are from other US companies, those companies may rely on imports and thus be forced to raise prices to their customers. And if, in retaliation, other countries impose tariffs on US goods, this will affect US exporters and discourage them from investing.

For many multinational companies, whether based in the USA or elsewhere, supply chains involve many countries. New tariffs will force them to rethink which suppliers to use and where to locate production. The resulting uncertainty can cause them to delay or cancel investments.

Uncertainty has also been caused by the frequent changes in the planned level of tariffs. With the Trump administration using tariffs as a threat to get trading partners to change policy, the threatened tariff rates have varied depending on how trading partners have responded. There has also been uncertainty on just how the tariff policy will be implemented, making it more difficult for businesses to estimate the effect on them.

Then there are serious issues for the longer term. Other countries will be less willing to sign trade deals with the USA if they will not be honoured. Countries may increasingly look to diverting trade from the USA to other countries.

In an interview with Joe Rogan for his podcast, The Joe Rogan Experience, just before the US election, Donald Trump stated that, “To me, the most beautiful word – and I’ve said this for the last couple of weeks – in the dictionary today and any is the word ‘tariff’. It’s more beautiful than love; it’s more beautiful than anything. It’s the most beautiful word. This country can become rich with the use, the proper use of tariffs.”

President-elect Trump has stated that he will impose tariffs on imports of 10% or 20%, with 60% and 100% tariffs on imports from China and Mexico, respectively. This protection for US industries, combined with lighter regulation, will, he claims, provide a stimulus to the economy and help create jobs. The revenues will also help to reduce America’s budget deficit.

But it is not that straightforward.

Problems with tariffs for the USA

Imposing tariffs is likely to reduce international trade. But international trade brings net benefits, which are distributed between the participants according to the terms of trade. This is the law of comparative advantage.

In the simple two-country case, the law states that, provided the opportunity costs of producing various goods differ between the two countries, both of them can gain from mutual trade if they specialise in producing (and exporting) those goods that have relatively low opportunity costs compared with the other country. The total production and consumption of the two countries will be higher.

So if the USA has a comparative advantage in various manufactured products and a trading partner has a comparative advantage in tropical food products, such as coffee or bananas, both can gain by specialisation and trade.

If tariffs are imposed and trade is thereby reduced between the USA and its trading partners, there will be a net loss, as production will switch from lower-cost production to higher-cost production. The higher costs of less efficient production in the USA will lead to higher prices for those goods than if they were imported.

At the same time, goods that are still imported will be more expensive as the price will include the tariff. Some of this may be borne by the importer, meaning that only part of the tariff is passed on to the consumer. The incidence of the tariff between consumer and importer will depend on price elasticities of demand and supply. Nevertheless, imports will still be more expensive, allowing the domestically-produced substitutes to rise in price too, albeit probably by not so much. According to work by Kimberly Clausing and Mary E Lovely for the Peterson Institute (see link in Articles below), Trump’s proposals to raise tariffs would cost the typical American household over $2600 a year.

The net effect will be a rise in inflation – at least temporarily. Yet one of Donald Trump’s pledges is to reduce inflation. Higher inflation will, in turn, encourage the Fed to raise interest rates, which will dampen investment and economic growth.

Donald Trump tends to behave transactionally rather than ideologically. He is probably hoping that a rapid introduction of tariffs will then give the USA a strong bargaining position with foreign countries to trade more fairly. He is also hoping that protecting US industries by the use of tariffs, especially when coupled with deregulation, will encourage greater investment and thereby faster growth.

Much will depend on how other countries respond. If they respond by raising tariffs on US exports, any gain to industries from protection from imports will be offset by a loss to exporters.

A trade war, with higher tariffs, will lead to a net loss in global GDP. It is a negative sum game. In such a ‘game’, it is possible for one ‘player’ (country) to gain, but the loss to the other players (countries) will be greater than that gain.

Donald Trump is hoping that by ‘winning’ such a game, the USA could still come out better off. But the gain from higher investment, output and employment in the protected industries would have to outweigh the losses to exporting industries and from higher import prices.

The first Trump administration (2017–21), as part of its ‘America First’ programme, imposed large-scale tariffs on Chinese imports and on steel and aluminium from across the world. There was wide-scale retaliation by other countries with tariffs imposed on a range of US exports. There was a net loss to world income, including US GDP.

Problems with US tariffs for the rest of the world

The imposition of tariffs by the USA will have considerable effects on other countries. The higher the tariffs and the more that countries rely on exports to the USA, the bigger will the effect be. China and Mexico are likely to be the biggest losers as they face the highest tariffs and the USA is a major customer. In 2023, US imports from China were worth $427bn, while US exports to China were worth just $148bn – only 34.6% of the value of imports. The percentage is estimated to be even lower for 2024 at around 32%. In 2023, China’s exports to the USA accounted for 12.6% of its total exports; Mexico’s exports to the USA accounted for 82.7% of its total exports.

It is possible that higher tariffs could be extended beyond China to other Asian countries, such as Vietnam, South Korea, Taiwan, India and Indonesia. These countries typically run trade surpluses with the USA. Also, many of the products from these countries include Chinese components.

As far as the UK is concerned, the proposed tariffs would cause significant falls in trade. According to research by Nicolò Tamberi at the University of Sussex (see link below in Articles):

The UK’s exports to the world could fall by £22 billion (–2.6%) and imports by £1.4 (–0.16%), with significant variations across sectors. Some sectors, like fishing and petroleum, are particularly hard-hit due to their high sensitivity to tariff changes, while others, such as textiles, benefit from trade diversion as the US shifts demand away from China.

Other badly affected sectors would include mining, pharmaceuticals, finance and insurance, and business services. The overall effect, according to the research, would be to reduce UK output by just under 1%.

Countries are likely to respond to US tariffs by imposing their own tariffs on US imports. World Trade Organization rules permit the use of retaliatory tariffs equivalent to those imposed by the USA. The more aggressive the resulting trade war, the bigger would be the fall in world trade and GDP.

The EU is planning to negotiate with Trump to avoid a trade war, but officials are preparing the details of retaliatory measures should the future Trump administration impose the threatened tariffs. The EU response is likely to be strong.

Gold has always held an allure and with the price of gold on international markets trending upwards since October 2022 (see Figure 1: click here for a PowerPoint), people seem to be attracted to it once again. The price reached successively higher peaks throughout 2023 before surging to above $2300 per oz in 2024 and peaking at $2425.31 per oz on 20 May 2024.

While gold tends to become attractive during wartime, economic uncertainty and bouts of inflation, all of which have characterised the last few years, the sustained price rise has perplexed market analysts and economists. The rally had been expected to peter out over the past 20 months. But, as the price of gold rose to sustained higher levels, with no significant reversals, some analysts have speculated that it is not the typical short-term factors which are driving the increased demand for and price of gold but more fundamental changes in the global economic system.

This blog will first discuss the typical short-term factors which influence gold prices before discussing the potential longer-term forces that may be at work.

Short-term factors

So, what are the typical short-term economic forces which drive the demand for gold?

The most significant are the real rates of interest on financial assets. These rates represent the opportunity cost of holding an asset such as gold which offers no income stream. When the real return from financial assets like debt and equity instruments is low, the demand for and price of gold tends to be high. In contrast, when the real return from such assets is high, the price of gold tends to be lower. An explanation for this is that real rates of return are strongly related to inflation rates and investors perceive gold as a hedge against inflation since its price is positively correlated with a general rise in prices. Higher unexpected inflation reduces the real rate of return of securities like debt and equity whose value is derived from cash flows anticipated in the future. In such circumstances, gold become an attractive alternative investment. As inflationary expectations decline, real returns from financial assets should rise, and the demand for gold should fall.

The relationship between real returns, proxied by the yield on US 10-year TIPS (Treasury inflation-protected securities), and gold prices can be used to examine this explanation. Real returns rose steadily in the aftermath of the COVID-19 pandemic. Yet the price of gold, which rose during the early stages of the pandemic in 2020, has not fallen. Instead, it has remained at elevated levels for much of that time (see Figure 2: click here for a PowerPoint).

There have been short periods when changes in real returns seemed to have a high correlation with changes in gold prices. In late 2022, for example, falling real rates coincided with rising gold prices. The same pattern was repeated between October and December 2023. However, when real returns rose again in the New Year of 2024, in response to stubbornly higher expected inflation and the expectation of ‘higher-for-longer’ interest rates, particularly in the USA, gold prices continued to rise. Indeed, across the 5-year period the correlation coefficient between the two series is actually positive at 0.268, showing little evidence supporting this explanation for the pattern for the gold price.

Real returns in the USA, however, may not be the correct ones to consider when seeking explanations for the pattern of gold’s price. Much of the recent demand is from China. Analysts suggest that Chinese investors are looking for a safe asset to hold as their economy stagnates and real returns from alternatives, like domestic property and equity, have decreased. Further, there are some concerns that the Chinese currency, the renminbi, may be undervalued in response to the sluggish growth. Holding gold is a good hedge against inflation (currency depreciation produces inflationary pressure). Consequently, the Chinese market may be exerting pricing power in relation to real returns in a way not seen before (see the Dempsey and Leng FT article linked below).

However, some analysts suggest that the rise in price is disproportionate to these short-term factors and point to potential long-term structural changes in the global financial order which may produce significant changes in the market for gold.

Long-term factors

Since 2018, there have been bouts of gold purchasing by central banks around the world. In contrast to the 1990s and 2000s, central banks have been net purchasers since 2010. The purchasing fell back during the coronavirus pandemic but has surged again, with over 1000 metric tonnes purchased in both 2022 and 2023 (see Figure 3: click here for a PowerPoint).

Analysts have pointed to similarities between the recent pattern and central bank purchases of gold during the late 1960s and early 1970s (see The Conversation article linked below). Then, central banks sought to diversify themselves from dollar-denominated assets due to concerns about higher inflation in the USA and its impact on the value of the US dollar. Under the Bretton Woods fixed exchange rate system, central banks could redeem dollars for gold from the US Federal Reserve at a fixed rate. The pressure on the USA to redeem the gold led to the collapse of the Bretton Woods fixed exchange rate system.

While the current period of central bank purchases does not appear to be related to expected inflation, some commentators suggest it could signal a regime change in the global financial system as significant as the collapse of Bretton Woods. The rise of Chinese political power and the resurgence of US isolationist tendencies portend an increasingly multipolar geopolitical scene. Such concerns may cause central bankers to diversify away from dollar denominated assets to avoid being caught out by geopolitical tensions. Gold may be perceived as an asset through which investors can hedge that risk better.

Indeed, the rise in demand among Chinese investors may indicate a reluctance to hold US assets due to their risk of seizure during heightened geopolitical tensions between China and the USA. Chinese holdings of US financial assets as a percentage of GDP are back to the level they were  when the country joined the World Trade Organisation (WTO) in 2001 (see the Rana Foroohar FT article linked below). Allied to this is an increasing tendency to repatriate gold bullion from centres such as London and New York.

Added to these worries about geopolitical risk are concerns about traditional safe-haven assets – government debt securities. US government budget deficits and debt levels continue to rise. Similar patterns are observed across many developed market economies (DMEs). Analysts are concerned such debts are reaching unsustainable levels (economist.com). The view is that at some point, perhaps soon, a tipping point will be reached where investors recognise this. They will demand higher rates of return on these government debt securities, pushing yields up and prices down (bond yields and prices have a negative relationship).

In expectation of this, investors may be wary of holding such government debt securities and move to hold gold as an alternative safe-haven asset to avoid potential capital losses. However, there has been no sign of this behaviour in bond prices and yields yet.

Finally, there are economists who argue that the increased demand for gold is caused by a different regime-change in the global economy. This is not one driven by geopolitics, but by changing inflationary expectations – from a low-inflation, low-interest-rate environment to a higher-inflation, higher-interest-rate environment.

Some of the anticipation relating to inflation is derived from the persistent fiscal stimulus, evidenced by the higher government debt levels described above, coupled with the long period of monetary stimulus (quantitative easing) in developed market economies during the 2010s.

Further, some economists highlight the substantial capital investment needed for the green transition and reindustrialisation. While the financing for this capital investment may absorb some of the excess money flowing around financial markets, the scale involved will create a great demand for resources, fuelling inflation and raising the cost of capital as borrowers compete for resources.

Finally, the demographic forces from an aging population will also cause inflationary pressures. Rising dependency ratios across many developed market economics will create shortages, particularly of labour. This persistent scarcity of labour will continually drive up wages and prices, fuelling inflation and the demand for gold.

Conclusion

The recent surge in the price of gold has led to great interest by investors, financial market analysts and economists. At first, there was a perception that the price increase was similar to recent history and driven by short-term decreases in the real rate of return from financial assets, which reduced the opportunity cost of holding gold.

However, as the upward trend in the price of gold has persisted and does not seem to be explained by changes in real interest rates, economists have considered other reasons that might signal longer-term significant changes in the global financial system. These relate to changing geopolitical risk derived from an increasingly multipolar environment, concerns about the sustainability of government debt levels and expectations of persistently higher inflation in the world economy.

Only time will tell whether these explanations prove correct. If inflationary pressures subside, particularly in the USA, and if real returns from financial assets rebound, a decrease in the demand for and price of gold will suggest that the previous rise was driven by short-term forces.

If prices don’t fall back, it will only fuel the debate that it is a sign of significant changes in the global financial order.

Climate change is not just an environmental challenge: its socioeconomic impacts are profound and far-reaching, touching every aspect of society. From agriculture to health, from urban infrastructure to coastal communities, the effects of climate change are evident and escalating.

The far-reaching effects

In agriculture, rising temperatures, more intense and frequent heatwaves and changing precipitation patterns pose significant threats to food security.1, 2 Crop yields decline as extreme weather events become more frequent and unpredictable, leading to increased food prices and economic instability. Smallholder farmers, who often lack the resources to adapt, are particularly vulnerable, exacerbating rural poverty and food insecurity.3

Coastal communities face the dual threats of sea-level rise and more intense storms.4 Erosion and inundation damage homes, infrastructure and livelihoods, displacing populations and disrupting local economies. The loss of coastal ecosystems further compounds these challenges, reducing natural defences against storm surges and exacerbating the impacts of climate-related disasters.

Health systems strain under the burden of climate-change-induced heatwaves, air pollution and the spread of vector-borne diseases.5, 6 Heat-related illnesses increase as temperatures rise, particularly affecting vulnerable populations such as the elderly and outdoor workers. Air pollution exacerbates respiratory conditions, leading to higher healthcare costs and decreased productivity. Vector-borne diseases, such as malaria and dengue fever, expand into new regions, placing additional strain on already overburdened health systems.

Displacement due to climate-related disasters amplifies social inequalities and challenges urban planning and infrastructure.7 Vulnerable communities, often located in low-lying areas or informal settlements, bear the brunt of climate impacts, facing the loss of homes, livelihoods and community cohesion. Inadequate housing and infrastructure increase the risks associated with extreme weather events, perpetuating cycles of poverty and vulnerability.

Furthermore, climate change exacerbates existing socioeconomic disparities, disproportionately affecting marginalised and vulnerable populations. Indigenous communities, women, children and people living in poverty are often the hardest hit, lacking access to resources, information, and adaptive capacity.8

Policy responses

Addressing the socioeconomic impacts of climate change requires co-ordinated action across sectors and scales. Policy interventions, such as investment in climate-resilient infrastructure and the promotion of sustainable agriculture practices, are essential for building resilience and reducing vulnerability. Community-led initiatives that prioritise local knowledge and empower marginalised groups are also critical for fostering adaptive capacity and promoting social equity.

To address these challenges, projects like CROSSEU, the new €5 million Horizon Europe project (that I have the pleasure to be part of), play a crucial role in enhancing our understanding of these impacts and developing actionable strategies for resilience and adaptation. One of the key contributions of CROSSEU lies in its development of a Decision Support System (DSS) that integrates tools, measures, and policy options to address these risks in a cross-sectoral and cross-regional perspective. This DSS will support (and hopefully improve) decision-making processes at various levels, from local to EU-wide, and facilitate the adoption of evidence-based policies and measures to enhance resilience and mitigate the impacts of climate change.
