TOKYO, Jan 28 (Reuters) - The yen rallied broadly on Monday as a slide in regional stock markets heightened risk aversion and crimped demand for higher-yielding currencies and assets.
China's main stock index tumbled more than 7 percent <
>, as heavy snow across central and eastern China stoked worries about damage to the economy, while Japanese shares fell more than 3.5 percent. [ ]"It's the familiar pattern of risk aversion caused by falls in share prices," said Koji Fukaya, senior currency strategist for Deutsche Securities.
Stock markets remain a driving force for currencies as market players seek clues on whether to tiptoe back to risky carry trades, in which the low-yielding yen is used as a source of cheap funds to buy higher-yielding currencies.
Sterling fell against the yen and the dollar after a senior Bank of England official said interest rates need to be cut to prevent a sharp slowdown in British growth.
The dollar fell 0.6 percent to 106.10 yen <JPY=>. The high-yielding Australian dollar fell 0.8 percent against the yen <AUDJPY=R> and the New Zealand dollar slumped 0.9 percent versus the yen <NZDJPY=R>.
The euro fell 0.6 percent to 155.67 yen <EURJPY=R> but was steady against the dollar at $1.4671 <EUR=>.
Sterling retreated after BoE policymaker David Blanchflower told the Guardian newspaper in an interview that the central bank needs to cut rates and stop worrying about inflation. [
]The remarks helped stoke expectations the BoE will cut rates by a quarter-point at its policy meeting in February, taking them down to 5.25 percent and making the pound less alluring for yield-seeking investors. The BoE made its first rate cut for over two years in December.
The pound fell to $1.9750 <GBP=>, down 0.4 percent compared with $1.9820 in late U.S. trade on Friday.
RATE DIFFERENTIALS
The Federal Reserve is also seen cutting rates after a two-day policy meeting ending on Wednesday by as much as a half-point following last week's 75-basis-point cut, the biggest in a quarter-century, in a rare move between scheduled meetings.
Market players are awaiting a slew of data this week for clues on the U.S. economy's health, including new home sales figures later in the day and the monthly jobs report on Friday.
While the troubles in the U.S. economy and banking system have hurt the dollar, investors are also selling currencies like the pound where interest rates are expected to head lower.
"If the Fed falls short with only a 25-basis point rate cut or no rate cut, that may badly affect equity markets and put upward pressure on the yen," said Masafumi Yamamoto, head of FX strategy for Japan at Royal Bank of Scotland in Tokyo.
A steeper, 50 basis-point rate cut may lend support to U.S. shares prices and give the dollar some near-term relief against the yen, but the longer term implications could be negative for the dollar, said Yuji Matsuura, joint general manager for Aozora Bank's foreign exchange and derivatives trading group.
"As interest rate differentials will shrink, it will become harder to sell the yen and easier to sell the dollar," he said.
Even if the Fed cuts interest rates by half a point and that in turn boosts U.S. stock markets, the dollar will likely struggle to rise sharply above 110 yen, Matsuura said.
Due to the Fed's rate cut last week, the rate differential between the U.S. benchmark federal funds rate and Japan's key overnight call rate has shrunk to 3 percentage points, down from 3.75 percentage points in December.
Events later in the day will feature speeches by a few ECB officials and President George W. Bush's State of the Union address.
Bush and congressional leaders have been trying to thrash out a $150 billion stimulus package to help to limit the economy's downturn this year from a reeling housing market.
In television interviews at the weekend, U.S. Treasury Secretary Henry Paulson said the Senate should quickly approve the stimulus proposal to boost the sagging economy. (Additional reporting by Eric Burroughs)
