The dollar kept spiraling lower Friday, hitting another new low against the euro, as worries about the U.S. economy depress the currency and raise thorny issues in Europe about how to cope with the growing gap.

The euro flew past its previous high to hit $1.5238, before subsiding later in the day to $1.5192. The euro topped $1.50 this week for the first time since its 1999 introduction, then surged above $1.51 after markets took comments from Fed Chairman Ben Bernanke as a sign that yet more U.S. rate cuts are on the way.
