Market participants are waiting for the Federal Open Market Committee's (FOMC) statement on the monetary policy later in the day and the European Central Bank’s (ECB) monetary policy decision on Thursday when President Mario Draghi was expected to take fresh action, following his last week's pledge to do whatever it took to save the euro.
However, the Fed will want to wait for more data, on employment in particular, before considering any significant policy changes. Analysts expect the Fed to refrain from taking further policy action at the August FOMC meeting and see the September FOMC meeting as a more likely near-term decision point.
“Despite comments by the German Finance Ministry that it sees no need to give the ESM bailout fund a banking license, market hopes of ECB action Thursday remain in place, helping to give some support to markets and the EUR. However, the Fed is unlikely to deliver fresh stimulus measures following the conclusion of its two day meeting Wednesday,” said a note from Credit Agricole.
