The euro fell against most of its peers after Portugal was forced to pay more at a debt auction than it has in the past, indicating concern the region is struggling to contain its sovereign-debt crisis.
Portugal sold 1 billion euros ($1.4 billion) of securities due September 2013. The bonds were issued at an average yield of 5.993 percent, the country’s debt management agency said. That compares with an average yield of 4.086 percent at a previous auction of the same-maturity debt on Sept. 8. The auction attracted bids for 1.6 times the amount offered, compared with a bid-to-cover ratio of 1.9 in September.
