The 16-nation euro is starting the week stronger against the U.S. dollar after moves by European leaders to allay worries about the eurozone economy.
The euro bought $1.2457 in morning European trading Monday, up from $1.2364 on Friday in New York. The British pound is up to $1.4912 from $1.4799 while the dollar is little changed against the Japanese yen, purchasing 90.72 yen compared with 90.73 yen in New York trading.
The euro gained strength last week after EU leaders meeting in Brussels said they would publish results of "stress tests" of Europe's 25 biggest banks in July.
Concern that Spain could follow Greece in requiring financial aid also receded somewhat Friday after a successful bond auction and support from EU leaders.
