OPINION 25.11.2021 Keith Pilbeam Keith Pilbeam is Professor of Economics, City, University of London | theconversation.com T he euro has weakened against the US dollar since the beginning of 2021, from around US$1.23 to its current exchange rate of US$1.13. at's a fall of about 9%, which is significant, especially since these are the two major currencies of the world. e drop has also intensified in November, falling 3% since the turn of a month, which has seen vio- lence in European capitals over COVID restrictions, migrant problems at the Be- larus-Poland border and Russian troops amassing on the border of Ukraine. e decline should be seen in a broad- er context, though. e euro is still stronger than a couple of years ago, when it was about US$1.10. It also went through some heavy weekly volatility from February to April 2020 in the early part of the COVID pandemic, bouncing between about US$1.07 and US$1.13 at a time when lots of investors were flee- ing to the US dollar for safety and there was much uncertainty about what lock- downs would mean. Explaining currency movements on a weekly or even monthly basis is well known to be extremely difficult, espe- cially when it comes to major econo- mies like the US and the countries in the eurozone. But certainly we need to look at what is happening in both regions and not just one or the other. Using this simple idea, there are several explana- tions for the recent euro depreciation. Inflation differences e first explanation relates to the Federal Reserve and the European Cen- tral Bank (ECB) stimulating their econ- omies using quantitative easing (QE), which is essentially creating money to buy financial assets such as government bonds from banks and other major in- vestors. Both central banks have been doing this extensively since the start of the pandemic. However, with annual inflation in the US now reaching a serious level of 6.2%, compared with a less troublesome 4.1% in the eurozone, the feeling is that the Fed will end its asset purchases sooner. is is because increasing the money supply has the potential to stoke in- flation. Indeed, the Fed has recently already started "tapering" or slowing down the rate of QE with a view to stopping it in the second half of 2022. On the other hand, the ECB has been discussing a replacement for its US$2.2 trillion (£1.7 trillion) QE programme when it ends in March 2022. Connected to this is an increasing ex- pectation that the US may also have to begin a series of rises to interest rates from the middle of 2022 to curb infla- tion, while ECB president Christine Lagarde has just made it clear that the ECB is unlikely to start raising rates until at least 2023. ese emerging dif- ferences in the monetary-policy stanc- es of the US and eurozone have clearly favoured a strengthening of the dollar (since QE and lower interest rates tend to make a currency depreciate). COVID and politics A second pivotal factor has been the recent relative strength of the US econ- omy in its recovery from the pandemic compared with the eurozone. In 2021, the US is forecast by the International Monetary Fund to grow 6% compared to 5% in the eurozone, while in 2022 they are respectively expected to grow 5.2% and 4.3%. Again, this points to dol- lar strength. More COVID lockdowns in the US seem unlikely (even though cases are rising again), though not in the euro- zone area, where the rate of infections has been picking up sharply in re- cent weeks in countries like Germany, France, the Netherlands, Austria and Belgium. Austria is now back in lock- down, and other eurozone countries could follow suit. A final driver of the recent strength of the dollar is greater political stability. e Biden administration still has three years in office and has recently succeed- ed in passing its US$1.7 trillion Build Back Better stimulus package. By contrast, countries in the euro- zone face a period of greater political instability. Germany is seeing the 16 years of relative stability under Angela Merkel coming to an end. e ques- tion of whether Emmanuel Macron will succeed in the French elections in April 2022 against Marine Le Pen is also weighing on investors' minds, as are the continued trade frictions between the EU and the UK over Brexit. While short-term currency move- ments are very difficult to predict, there are many reasons to believe that the re- cent period of euro weakness will con- tinue. is is making imports to the euro- zone more expensive – not least energy – and while it has some benefits for a major exporter like Germany, it also un- dermines the credibility of the eurozone as a global economic force. e gamechanger might be if the ECB acknowledged that there is an infla- tion problem that needs to be tackled, by ending its experiment with QE and beginning the process of raising inter- est rates. at, however, does not look likely any time soon. The euro is plunging – and probably won't bounce back soon Euro vs US dollar
