Analysts will also look for clues about the interest rate cycle given mixed signals from several recent Fed speakers.
Chicago Fed President Charles Evans, a well known non-voting dove, suggested on Tuesday that with low inflation in the United States and globally, one of the biggest risks is prematurely withdrawing from an accommodative policy.
On the other hand, Philadelphia Fed President Charles Plosser, a voting hawk, had suggested that quantitative easing is not the answer to low inflation.
The Swedish crown, meanwhile, was one of the biggest movers on Wednesday, falling versus the euro, after the Riksbank signalled it was moving closer to cutting interest rates.
Dealers from Scandinavian banks said the central bank's lowering of its projected path for rates opened the way to a push towards 9.05 crowns per euro, although there would be some caution ahead of inflation numbers due on Thursday.
The euro rose about 0.4 percent against the Swedish crown near 8.98.
One striking trend on the majors since last week is the euro's resilience in the face of signals from the European Central Bank that it is prepared to consider outright money printing to support growth if need be.
A number of dealers said the euro zone common currency was being supported by China's need to re-order the balance of currencies it holds in its reserves after buying billions of dollars last month to weaken the yuan. Similarly, many pointed to signs of intervention by South Korean authorities overnight that may support the euro.
The refloating of the euro zone's struggling southern states on bond markets, exemplified on Wednesday by Greece's announcement of its first bond sale in four years, has also drawn capital back into Europe this year.
The euro was up 0.1 percent against the dollar at $1.38, and firmly in the upper half of its recent range.
