After two weeks of negotiations between the 195 countries attending the COP21 climate change conference in Paris, a deal has been reached on tackling climate change. Although the deal still has to be ratified by countries, this is a major step forward in limiting global warming. Before it can formally come into force, it must have been ratified by at least 55 countries, accounting for at least 55% of global greenhouse gas emissions.
The deal goes much further than previous agreements and includes the following:
- A limit on the increase in global temperatures to ‘well below’ 2°C above pre-industrial levels and efforts pursued to limit it to 1.5°C.
- A recognition that the pledges already made ahead of the conference by 186 countries and incorporated into the agreement are insufficient and will only limit global temperature rise to 2.7°C at best.
- Countries to update their emissions reductions commitments every five years – the first being in 2020. Such revised commitments should then be legally binding.
- A global ‘stocktake’ in 2023, and every five years thereafter, to monitor countries’ progress in meeting their commitments and to encourage them to make deeper cuts in emissions to reach the 1.5°C goal. This requires a process of measurement and verification of countries’ emissions.
- To reach a peak in greenhouse gas emissions as soon as possible and then to begin reducing them and to achieve a balance between sources and sinks of greenhouse gases (i.e. zero net emissions) in the second half of this century.
- Developed countries to provide the poorest developing countries with $100bn per year by 2020 to help them reduce emissions. This was agreed in Copenhagen, but will now be continued from 2020 to 2025, and by 2025 a new goal above $100bn per year will be agreed.
- The development of market mechanisms that would award tradable credits for green projects and emissions reductions.
- A recognition that the ‘loss and damage’ associated with climate-related disasters can be serious for many vulnerable developing countries (such as low-lying island states) and that this may require compensation. However, there is no legal liability on developed countries to provide such compensation.
Perhaps the major achievement at the conference was a universal recognition that the problem of global warming is serious and that action needs to be taken. Mutual self interest was the driving force in reaching the agreement, and although it is less binding on countries than many would have liked, it does mark a significant step forward in tackling climate change.
But why did the conference not go further? Why, if there was general agreement that global warming should be tackled and that global temperature rise should ideally be capped at 1.5°C, was there not a binding agreement on each country to apply this cap?
There are two reasons.
First, it is very difficult to predict the exact relationship, including its timing, between emissions and global temperature rise. Even if you could make limits to emissions binding, you could not make global temperature rise binding.
Second, even if there is general agreement about how much emissions should be reduced, there is no general agreement on the distribution of these reductions. Many countries want to do less themselves and others to do more. More specifically, poor countries want rich countries to do all the cutting while many continue to build more coal-fired power stations to provide the electricity to power economic development. The rich countries want the developing countries, especially the larger ones, such as China, India and Brazil to reduce their emissions, or at least the growth in their emissions.
Then there is the difference between what countries vaguely pledge at a global conference and what they actually do domestically. Many developed countries are keen to take advantage of currently cheap fossil fuels to power economic growth. They are also still investing in alternative sources of fossil fuels, such as through fracking.
As we said in the previous blog, game theory can shed some useful insights into the nature and outcome of climate negotiations. ‘The global optimum may be for a strong agreement, binding on all countries. The Nash equilibrium, however, may be a situation where countries push for their own interests at the expense of others, with the final agreement being much more minimalistic.’
‘Minimalistic’ may be too strong a description of the outcomes of the Paris conference. But they could have been stronger. Nevertheless, judged by the outcomes of previous climate conferences, the deal could still be described as ‘historic’.

As we saw in the blog post Down down deeper and down, or a new Status Quo?, for many countries there is now a negative rate of interest on bank deposits in the central bank. In other words, banks are being charged to keep liquidity in central banks. Indeed, in some countries the central bank even provides liquidity to banks at negative rates. In other words, banks are paid to borrow!
But, by definition, holding cash (in a safe or under the mattress) pays a zero interest rate. So why would people save in a bank at negative interest rates if they could get a zero rate simply by holding cash? And why would banks not borrow money from the central bank, if borrowing rates are negative, hold it as cash and earn the interest from the central bank?
These questions are addressed in the article below from The Economist. It argues that to swap reserves for cash is costly to banks and that this cost is likely to exceed the interest they have to pay. In other words, there is not a zero bound to central bank interest rates, either for deposits or for the provision of liquidity; and this reflects rational behaviour.
But does the same apply to individuals? Would it not be rational for banks to charge customers to deposit money (a negative interest rate)? Indeed, there is already a form of negative interest rate on many current accounts; i.e. the monthly or annual charge to keep the account open. But would it also make sense for banks to offer negative interest rates on loans? In other words, would it ever make sense for banks to pay people to borrow?
Read the folowing article and then try answering the questions.

Are emerging markets about to experience a credit crunch? Slowing growth in China and other emerging market economies (EMEs) does not bode well. Nor does the prospect of rising interest rates in the USA and the resulting increase in the costs of servicing the high levels of dollar-denominated debt in many such countries.
According to the Bank for International Settlements (BIS) (see also), the stock of dollar-denominated debt in emerging market economies has doubled since 2009 and this makes them vulnerable to tighter US monetary policy.
Weaker financial market conditions combined with an increased sensitivity to US rates may heighten the risk of negative spillovers to EMEs when US policy is normalised. …
Despite low interest rates, rising debt levels have pushed debt service ratios for households and firms above their long-run averages, particularly since 2013, signalling increased risks of financial crises in EMEs.
But there is another perspective. Many emerging economies are pursuing looser monetary policy and this, combined with tighter US monetary policy, is causing their exchange rates against the dollar to depreciate, thereby increasing their export competitiveness. At the same time, more rapid growth in the USA and some EU countries, should also help to stimulate demand for their exports.
Also, in recent years there has been a large growth in trade between emerging economies – so-called ‘South–South trade’. Exports from developing countries to other developing countries has grown from 38% of developing countries’ exports in 1995 to over 52% in 2015. With technological catch-up taking place in many of these economies and with lower labour and land costs, their prospects look bright for economic growth over the longer term.
These two different perspectives are taken in the following two articles from the Telegraph. The first looks at the BIS’s analysis of growing debt and the possibility of a credit crunch. The second, while acknowledging the current weakness of many emerging economies, looks at the prospects for improving growth over the coming years.

Questions
- How does an improving US economy impact on emerging market economies?
- Will the impact of US monetary policy on exchange rates be adverse or advantageous for emerging market economies?
- What forms does dollar-denominated debt take in emerging economies?
- Why has south–south trade grown in recent years? Is it consistent with the law of comparative advantage?
- Why is growth likely to be higher in emerging economies than in developed economies in the coming years?
The Federal Reserve chair, Janet Yellen, has been giving strong signals recently that the US central bank will probably raise interest rates at its December 16 meeting or, if not then, early in 2016. ‘Ongoing gains in the labor market’ she said, ‘coupled with my judgement that longer-term inflation expectations remain reasonably well anchored, serve to bolster my confidence in a return of inflation to 2%.’ This, as for many other central banks, is the target rate of inflation.
In anticipation of a rise in US interest rates, the dollar has been appreciating. Its (nominal) exchange rate index has risen by 24% since April 2014 (see chart below).
In the light of the sluggish eurozone economy, the ECB president, Mario Draghi, has been taking a very different stance. He has indicated that he stands ready to cut interest rates further and increase quantitative easing.
At the meeting on 3 December, the ECB did just that. It announced a further cut in the deposit rate, from –0.2 to –0.3 and an extension of the €60 billion per month QE programme from September 2016 to March 2017 (bringing the total by that time to €1.5 trillion – up from €1.1 trillion by September 2016).
Stock market investors had been expecting more, including an increase in the level of monthly asset purchases above €60 billion. Consequently stock markets fell. Both the German DAX and the French CAC 40 stock market indices fell by 3.6%. The euro also appreciated against the dollar by 2.7% on the day of the announcement. Nevertheless, since April 2014, the euro exchange rate index has fallen by 13%. Against the US dollar, the euro has depreciated by a massive 31%.
So what will be the consequences of the very different monetary policies being pursued by the Fed and the ECB? Are they simply the desirable responses to a lack of convergence of the economic performance of the US and eurozone economies? In other words, will they help to bring greater convergence between the two economies?
Or will the desirable effects of convergence be offset by other undesirable effects for the USA and the eurozone and also for the rest of the world?

George Osborne in his recent Autumn Statement, once again stressed that ‘the government is committed to strong, sustainable and balanced growth’. But while he plans to reduce government debt as a percentage of GDP, consumer debt is rising, both absolutely and as a percentage of household disposable income. The rise in household borrowing, and the resulting rise in consumer expenditure, has been the main factor driving economic growth. It has not been exports nor, until recently, investment, as the Chancellor had hoped. Indeed, investment in new housing is falling.
The Office for Budget Responsibility in its latest Economic and Fiscal Outlook forecasts that gross household debt will reach 163 per cent of household disposable income by 2021, up from 146% at the end of 2015.
Consumer gross debt includes both secured debt and unsecured debt. Secured debt is essentially debt secured on property (i.e. mortgages), while unsecured debt is largely in the form of credit card debt, overdrafts and personal loans.
The chart shows that from 2008 to 2013, gross debt fell as a percentage of personal disposable income. Following the financial crisis, banks were more cautious about lending as they sought to increase their capital and liquidity ratios. And consumers were more cautious about borrowing as the uncertainty made many people keen to reduce their debts. This decline in credit reversed the massive growth in household debt from 2000 to 2008: one of the contributing factors to the financial crisis. (Click here for a PowerPoint of the chart.)
But since late 2013, household debt – both secured and unsecured – has been rising. In absolute (nominal) terms, individuals’ debt is now £1.43 trillion, slightly above the previous high in 2008. And as the chart shows, the OBR forecasts that it will continue rising. This makes consumers more vulnerable to adverse economic shocks, such as a downturn in emerging markets, another crisis in the eurozone or financial crises in other parts of the world.
And as consumer debt has been rising, the personal saving ratio (the ratio of saving to personal disposable incomes) has been falling and is now lower than before the financial crisis.
The rise in consumer borrowing has been of some concern to the Bank of England. Andy Haldane, the Bank’s Chief Economist, appearing before the Treasury Select Committee, warned that consumer credit, and in particular personal loans, had been ‘picking up at a rate of knots. That ultimately might be an issue that the Financial Policy Committee might want to look at fairly carefully.’
