European stocks fell and the euro plunged against the dollar Thursday after the ECB held its key rate steady despite calls by France and others for looser monetary policy.
The European single currency plunged moments after ECB President Mario Draghi said that a strong rise in the euro in recent weeks was a sign of market confidence. It ended the session at $1.3386, down from $1.3519 late on Wednesday in New York.
The ECB "will wait to see some negative impact of the appreciation of the euro on growth and inflation before it feels it needs to act," said Marie Diron, senior economic adviser to the Ernst & Young Eurozone Forecast.
For UniCredit counterpart Marco Valli, "Draghi confirmed that the ECB does not target the (euro's) exchange rate," while other economists felt that he had successfully talked the single currency down against the dollar.
In London, where the Bank of England also maintained its key rates, equities on the FTSE 100 index of top companies fell 1.06 percent to 6,228.42 points.
In Paris, the CAC 40 fell 1.15 percent to 3,601.05 points, while in Frankfurt the DAX 30 edged up 0.13 percent to 7,590.85 points, kept in positive territory by another raft of rosy economic data.

As widely predicted by analysts and ECB watchers, the central bank's policy-setting governing council voted to leave the main refinancing rate at a historic low of 0.75 percent, where it has been since July.
With ECB interest rates low and its latest anti-crisis bazooka -- the so-called OMT -- ready and primed for action, Draghi believes the bank has done what it needs to and it is now up to governments to resolve the long-running crisis, economists said.
"The Draghi speech was in the end quite accommodating," Alexandre Baradez of Saxo Bak in Paris.
"The ECB sees signs of recovery while remaining vigilant," he said.
France has triggered a debate this week that a strong euro could trample tender green shoots of recovery in the eurozone, even as Germany insists there was no cause for alarm just yet.
In London, The BoE also voted to freeze its key interest rate at a record-low 0.50 percent and maintain the level of its quantitative easing cash stimulus, despite the threat of a triple-dip recession in Britain.
The decision was in line with expectations and came as incoming BoE governor Mark Carney called for the bank to ready plans for a smooth eventual withdrawal of QE stimulus to avoid major disruption on markets.
