Euro Falls Toward One-Week Low Versus Dollar Before ECB

The euro fell toward a one-week low versus the dollar as European Central Bank policy makers prepared to meet tomorrow amid political and banking turmoil that threatens to renew the region’s sovereign-debt crisis.

The 17-nation currency slid against most of its 16 major peers as Spain’s premier resisted opposition calls to resign and Italy’s Banca Monte dei Paschi di Siena SpA faces criminal probes over losses it hid in 2008 and 2009 using derivatives. The euro declined as Greece’s finance minister said its strength is a concern. The yen weakened to a 32-month low against the dollar on speculation Japan will select a new central-bank chief committed to boosting monetary easing.
