NEW YORK, March 20 (Reuters) - The dollar rose to its highest in one week against the euro on Thursday as investors sold oil, gold and other commodities, repatriating their cash back into the beleaguered U.S. currency.
Oil went down as much as 4 percent <CLc1>, dipping earlier below $99 a barrel and commodities such as gold and platinum may post their biggest weekly losses in years, following a months-long rally.
As investors slashed their "long" exposure to these assets, they covered "short" positions in the dollar, lifting the currency from historic lows charted earlier this week, traders said.
"Commodity markets and currencies are very interconnected and as we see the system deleverage positions in oil and gold, the dollar is bouncing back," said Camilla Sutton, a currency strategist at Scotia Capital in Toronto.
In midday trading in New York, the euro was down 1.4 percent at $1.5419, well off Monday's record high of $1.5904 and chalking up its steepest one-day fall since early February. Still, the euro is up nearly 6 percent for the year <EUR=>.
The dollar erased earlier gains versus the yen and last traded little changed at 98.78 yen <JPY=>, after trading as high as 100.20 earlier in the session. Traders said a flow-driven market, and losses on the euro/yen cross weighed on the dollar.
Against the Swiss franc, the dollar bounced 1.5 percent to 1.0116 francs <CHF=>.
"The dollar is holding up remarkably well ... and I am wondering if the steep fall in commodity prices is causing stress among leveraged names and creating a short-term demand for dollars," said Neal Kimberley, head of FX sales at BTM-UFJ in London.
Kimberley added that the proximity of Easter holidays in Europe and the United States may be leading some investors to reduce dollar shorts ahead of the long weekend.
Pressure on the euro also mounted after Credit Suisse Group <CSGN.VX> said it might not make a profit in the first quarter of 2008 because of write-downs on debt securities. Credit Suisse shares were down 10 percent in European trading.
"Europe has also been hit by problems in the financial system," said Sutton at Scotia Capital.
ECB, BOE INJECT LIQUIDITY
With interest rates of just 2.25 percent, which are the second lowest among major economies and are set to fall further, the U.S. currency's potential for gains may be limited.
Markets are pricing in around a 70 percent chance of a 50- basis-point cut at the Federal Reserve's April meeting, adding to 300 basis points of easing administered since September.
"Low interest rates, set to move even lower, and a wide (albeit narrowing) external deficit are a bad combination for any currency, including the dollar," American Express Bank said in a note.
"The credit crisis remains far from over and a prolonged U.S. recession looks likely, with GDP growth staying below trend far into 2009," they said, lowering their dollar forecasts.
The European Central Bank and the Bank of England pumped 15 billion euros and 5 billion pounds, respectively, into the banking system on Thursday via short-term loans to help tide banks over the holiday period. For details, see [
