TOKYO, July 10 (Reuters) - The dollar edged up against a basket of currencies on Thursday as oil prices inched lower, but investors remained cautious due to worries about more credit-related losses and the economy.
Though the dollar found support from a dip in oil prices, traders were wary of oil surging back towards the record peak of $145.85 hit last week, as high energy costs undermine the weak U.S. economy and hurt the currency.
Oil settled at $136.05 a barrel <CLc1> on Wednesday after rising above $138 on escalating tensions between Iran and the West over Tehran's nuclear programme.
U.S. stocks fell on worries about financial institutions, with Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, the two largest U.S. mortgage funders, tumbling again on Wednesday on worries they would need to raise billions of dollars in additional capital.
Merrill Lynch <MER.N> shares fell more than 9 percent after Fitch Ratings said it may cut the U.S. investment bank's debt rating due to expected ongoing write-downs and diminished prospects for earnings. Merrill is among several big financial institutions due to report earnings next week.
"The market is focusing on the credit issue ahead of next week's earnings, and the dollar remains pressured as players keep a close eye on stocks, which have been falling on credit worries, and oil prices," said Mitsuru Sahara, a senior trader at Bank of Tokyo-Mitsubishi UFJ.
At the same time, the dollar was surprisingly resilient despite talk of more troubles in the U.S. financial sector, traders said.
"There is caution among dollar sellers, sensing that globally there may be a shared interest in keeping the dollar from sliding further," Sahara said.
The dollar index, which tracks the dollar's performance against six currencies, inched up 0.1 percent to 72.658 <.DXY>.
The dollar rose 0.2 percent to 106.94 yen <JPY=>.
The euro slipped 0.1 percent at $1.5723 <EUR=>.
The Aussie climbed 0.5 percent to $0.9601 <AUD=D4>, getting a boost from data showing Australian companies added 29,800 jobs in June, exceeding a forecast for a rise of 10,000, while the unemployment rate eased to 4.2 percent. [
]The Aussie had marked a three-week trough near $0.9475 on Wednesday when a key measure of consumer sentiment hit a 16-year low and further scaled back expectations for an interest rate hike.
BERNANKE, BoE AHEAD
A senior dealer at a European bank said downward revisions to first-quarter gross domestic product growth in the euro zone and data showing a fall in French and German exports in May would likely cap the euro's rise.
"The dollar and euro are in a tug-of-war as both have weak spots. The pair is likely to remain in tight ranges," he said.
Federal Reserve Chairman Ben Bernanke and Treasury Secretary Henry Paulson are slated to testify on regulatory restructuring before the House Financial Services Committee later on Thursday.
The dollar was boosted when Bernanke said on Tuesday that he was willing to keep open the emergency lending facility for investment banks into 2009. Investors were waiting to see if he would keep that soothing tone.
Sterling slipped 0.2 percent to $1.9800 <GBP=D4> before the Bank of England announces its interest rate decision at 1100 GMT.
The market expects the BoE to leave rates at 5.0 percent until it has a better idea of which is the greater evil, surging inflation or slowing economic growth.
Inflation is running at its fastest pace since the BoE won the power to set interest rates in 1997. (Additional reporting by Rika Otsuka; Editing by Brent Kininmont)
