The dollar is falling against the euro and most other major currencies ahead of a meeting of European Union leaders.

Investors expect that the summit, taking place Thursday, will produce some sort of agreement to help stem the region’s debt crisis. Talks will focus on a new aid package for Greece and ways to stop the debt crisis from spreading to Spain and Italy.
