On oil markets Brent prices tumbled more than 2% after Iran on Sunday agreed to curb its nuclear programme for the next six months in exchange for limited sanctions relief.
The deal, a preliminary accord laying the foundation for a comprehensive agreement, was reached after marathon talks in Geneva between Iran and the so-called P5+1 nations comprising the United States, China, France, Britain, Russia and Germany.
Brent North Sea crude for January delivery fell $2.33 or 2.10% to $108.72. New York's main contract, West Texas Intermediate for January, was down $1.37, or 1.45%, at $93.47.
"Brent had rallied last week in response to market talk that the negotiations weren't going so well, and what we see right now is a downward correction of prices after the deal," Victor Shum, managing director at IHS Purvin and Gertz in Singapore, told AFP.
However, he added that despite the falls Monday the impact of the deal on global supplies would be limited since many of the sanctions on Iran would remain in place for now.
The yen came under further selling pressure on Monday as investor confidence in the global outlook improved. Traders generally move into the yen in times of economic uncertainty as it is considered a safe bet.
