Monetary policy divergence between ECB and the Fed

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?

Will huge amounts of dollar-denominated debt held by many emerging economies make it harder to service these debts with an appreciating dollar?
How much will US exporters suffer from the dollar’s rise and what will the US authorities do about it?
Will currency volatility lead to currency wars and, if so, what will be their economic effects?
Will the time lags involved in the effects of the continuing programme of QE in the eurozone eventually lead to overheating? Already euro money supply is rising, on both narrow and broad measures.
