LONDON, July 16 (Reuters) - The dollar hit a five-week low against a currency basket on Thursday after strong earnings from JPMorgan tarnished the U.S. currency's safe-haven appeal and stoked some demand for currencies seen to be high-risk.
JPMorgan Chase
After spending much of the day down against the dollar, the euro and sterling hit the day's highs, prodding the dollar index to 79.204, its lowest since June 11, as JPMorgan's performance suggested it is recovering from the financial crisis.
"Traders and investors are buying pro-risk currencies like sterling and are selling yen after Q2 earnings from JP Morgan," said Neil Jones, head of hedge fund FX sales at Mizuho in London.
"The market is responding."
The euro
Some market participants said that trade may become choppy ahead of options expiries in the pair later in the day. IFR reported that 200 million euros' worth of options with a $1.41 strike price were due to expire at the New York cut.
The dollar index was at 79.255, down slightly on the day.
Sterling
The dollar
The yen trimmed gains against higher-risk currencies including the euro and sterling, although those currencies remained down on the day after risk-averse traders had picked up the Japanese currency earlier in the day.
"There are only two trades in FX markets at the moment - risk on and risk off," said Maurice Pomery, managing director at Strategic Alpha.
CITI, BOA NEXT
JPMorgan's strong performance comes on the heels of stellar
earnings from Goldman Sachs
Citigroup
Market participants were uncertain whether the two banks would fare as well as Goldman and JPMorgan did in April-June, and some said that weakness in any of these results may dent hopes for a global economic recovery, limiting demand for risk.
Analysts added that some traders took news of bailout talks
ending between the U.S. government and CIT Group
