TOKYO, Feb 22 (Reuters) - The dollar slipped on Monday as investors reassessed the chances of an earlier-than-expected interest rate hike by the Federal Reserve, while the euro was lifted by speculation of a quick bailout for Greece.
The yen fell as Shanghai's stock market <
> was relatively stable as it reopened after a week-long holiday, allaying fears that this month's decision by China's central bank to raise banks' required reserves could trigger a slide and hurt investors' risk appetite.The euro edged higher, helped by a report in German weekly Der Spiegel on Saturday that Germany's finance ministry had prepared plans for euro zone countries to help Greece. [
]Market players said the euro was also due for a short-covering bounce, given the way bets against the single European currency have piled up.
This week, all eyes will be on Fed chief Ben Bernanke's testimony in Congress on Wednesday and Thursday. Investors will be looking for clues on rates after the Fed surprised many by raising the discount rate last week. [
]"Comments from Bernanke are expected to be similar to ones by other Fed officials last week, playing down the possibility of an early hike in the fed funds rate," a trader at a Japanese bank said.
The euro rose 0.2 percent to $1.3633 <EUR=>, having rebounded from a nine-month low of $1.3443 hit on trading platform EBS on Friday after the Fed announced its decision to raise the discount rate.
The dollar index, which measures the dollar's value against a basket of currencies, dipped 0.2 percent to 80.469 <.DXY>, having retreated from an eight-month high of 81.342 hit on Friday.
Still, daily charts indicate a bullish outlook for the dollar with the 55-day moving average pushing above the 200-day moving average, indicating a "golden cross" has been established.
The next resistance for the dollar index is around 81.46, which is its June 8, 2009 high and then around 81.90, which is a 50 percent retracement of the index's fall from 89.62 to 74.17 last year.
The dollar managed to eke out gains against the yen, rising 0.2 percent to 91.69 yen <JPY=>, having hit a one-month high of 92.16 yen on Friday on EBS.
Currency markets took the Fed's discount rate decision last week as a signal the U.S. central bank was coming closer to tightening its benchmark rate despite assurances from Fed policymakers to the contrary.
The move triggered a rally in the greenback late last week, as higher rates would increase returns on dollar-denominated assets.
The dollar has since trimmed some of its gains, with tamer-than-expected U.S. consumer inflation data on Friday helping to ease some rate hike expectations.
Meanwhile, Der Spiegel reported on Saturday that Germany's finance ministry had prepared plans in which countries using the single currency would provide aid worth between 20 billion and 25 billion euros for debt-laden Greece. The ministry declined to comment on the report. [
]The euro has lost nearly 5 percent against the dollar since the start of the year as concerns about the fiscal health of Greece and some other euro zone countries intensified.
Currency speculators raised net euro short positions to a record high in the week ended Feb. 16, and traders say any bounce in the single currency is merely positioning adjustments.
In contrast, long bets on the dollar rose to their highest levels since the week of Sept. 23, 2008, according to the Commodity Futures Trading Commission released on Friday. [
].The pound <GBP=D4> was up 0.1 percent at $1.5486 but remained under pressure, hovering just above a nine-month low of $1.5345 struck on Friday after a surprisingly big fall in British retail sales. [
