NEW YORK, March 19 (Reuters) - The dollar slipped in choppy trading on Wednesday, as investors kept their bearish view on the low-yielding currency, while the yen firmed amid persistent worries about the health of the global financial system.
The dollar, however, recovered from the day's lows after news that regulators have lifted capital limits on mortgages that Fannie Mae <FNM.N> and Freddie Mac <FRE.N> may purchase. That could free up as much $200 billion in liquidity for the stricken mortgage market.
But market sentiment on the dollar remained decidedly negative as U.S. interest rates were still seen heading lower even after a 75 basis-point easing to 2.25 percent by the Federal Reserve on Tuesday.
The Fed move on Tuesday sparked a relief rally in equities, a tightening in a broad range of spreads, and a rebound in the dollar, although gains were fleeting. Investors resumed selling the dollar and buying the low-yielding yen and safe-haven Swiss franc on Wednesday.
U.S. stocks traded higher at midday, but price action was volatile, as investors remained uncertain about problems in the banking sector and the credit market.
"It's still a very dollar-negative environment as the Fed is expected to cut to about 1.50 percent by mid-year and this leaves the larger dollar sell-off trend still in place," said David Powell, a currency strategist, at IDEAglobal in New York.
"These moves that we see in the aftermath of the FOMC statement, the Fannie and Freddie news are really temporary and pullbacks do not imply a sustained dollar rebound," he added.
In midday New York trading, the euro was up 0.2 percent at $1.5653, off the day's highs at $1.5785 and more than 2 cents below Monday's record peak of $1.5904 <EUR=>.
The dollar was down 0.7 percent against the yen at 99.25 yen <JPY=>, trimming losses following the Fannie and Freddie announcement. It hit a 13-year trough of 95.71 yen on Monday.
The dollar was also down 0.2 percent against the Swiss franc trading at 1.0002 francs <CHF=>, way above record lows at 0.9637 struck last Monday.
The U.S. currency earlier took brief comfort from stronger-than-expected earnings reported by Lehman Brothers <LEH.N> and Goldman Sachs <GS.N> on Tuesday and Morgan Stanley <MS.N> on Wednesday.
STILL A BLEAK DOLLAR OUTLOOK
Analysts say the outlook for the dollar remains bleak with lower interest rates set to further cut the currency's yield appeal.
In its statement on Tuesday, the Fed indicated it could cut rates again, even though two voting members dissented against the depth of the latest move. The rate futures market has priced in a 58 percent probability of a 50 basis point cut to 1.75 percent <FEDWATCH>, down from about 94 percent early in New York trading.
Tuesday's rate cut is the latest in a series of emergency measures undertaken by the Fed to prevent the credit crisis from escalating. On Sunday, the Fed cut its discount rate by a quarter point and opened up discount window lending to major investment banks, a tool not used since the Great Depression.
But these measures did little to ease the market's concerns.
"A severe recession in the U.S. is clearly underway and data are likely to continue to come in thick and fast, providing evidence to that effect," said CitiFX in a research note."
Sterling, meanwhile, fell as minutes from the Bank of England's Monetary Policy Committee showed two of nine policymakers favored a rate cut this month, which added to speculation that UK rates are heading lower soon.
The pound fell as low as $1.9951 <GBP=> before trading back up at $1.9871, down 1 percent from late on Tuesday.
