* Asia stocks climb 1 pct as Bernanke reassures on banks
* Yen extends slide on grim economy, hedge fund selling
* Chart technicals help underpin stocks, hurt yen
* Gold and govt bonds retreat
By Eric Burroughs
HONG KONG, Feb 25 (Reuters) - Asia stocks edged up on Wednesday as reassuring comments from Federal Reserve Chairman Ben Bernanke sparked a rebound in battered financial shares, while the yen slid further on Japan's mounting economic and political troubles.
European shares were set to rise a little more than 1 percent, following on the gains in Asia and the United States, according to financial bookmakers.
Safe-haven government bonds retreated as investors shifted funds into riskier assets, while gold steadied after having soared in the past few weeks on mounting fears about the financial health of countries trying to contain the crisis.
Bernanke said major banks should weather the severe recession without being nationalised, remarks that put to ease some worries that the largest institutions may need to be taken over because of their heavy losses suffered in the global credit crisis. [
]The yen hit a three-month low beyond 97 to the dollar as investors have turned against Japan on the country's deepening recession that is the worst among major economies, forcing hedge funds and other market players to unwind bets favouring the yen.
Japanese exports plunged a record 45.7 percent in January from the previous year, data showed on Wednesday, pointing to another sharp contraction in economic activity in the first quarter of the year. [
]But Japanese shares were helped in part after the finance minister said the government was looking into share buying to support the market, a move that would ease the strain on the country's big banks suffering from hefty equity losses.
"It's good news, but what the market really wants is large-scale economic measures with the Japanese economy having deteriorated the most among developed countries," said Takahiko Murai, general manager of equities at Nozomi Securities in Tokyo.

Investors showed little reaction to U.S. President Barack Obama saying he has identified $2 trillion in costs that can be cut over the next decade as he seeks to offset big fiscal spending aimed at reviving the economy. [
]CHARTS LEND A HAND
Analysts said there were also technical reasons for the gains in stocks and the yen's slide.
The S&P 500 <.SPX> has held above its intraday lows touched last November that suggested the near-term downside may be limited, while the yen's fall took it through chart levels that spurred further selling.
The dollar climbed along with most major currencies against the beleaguered yen. The dollar struck a three-month peak of 97.35 before settling back to 97.00 yen <JPY=>, up 0.4 percent on the day.
On Tuesday the dollar broke through a series of chart resistance levels -- including the low of 95.70 struck in March last year and the 38.2 percent retracement of its slide between August and January.
The yen's fall even as stocks have slid has broken down one of the key correlations driving markets over the past year or so -- falling stocks spurring a drop in higher-yielding currencies against the yen as carry trades are unwound.
Traders have said the change suggests that many such carry trades -- using the low-yielding yen to buy higher-yielding currencies or assets -- have largely been unwound.
Gold dropped $6.15 an ounce at $956.30 <XAU=>, falling further away from 11-month highs above $1,000 hit last week as some safe-haven buying ebbed and investors booked profits.
Crude oil dipped 36 cents to $39.60 a barrel <CLc1> after climbing 4 percent the previous day along with the rebound in equity markets.
In government bonds, the benchmark 10-year Japanese yield rose 3.5 basis points to 1.300 percent <JP10YTN=JBTC>, the upper end of its tight range around 1.25 percent and 1.30 percent over the past two weeks.
U.S. Treasuries also lost ground, with the 10-year yield <US10YT=RR> rising about 2 basis points to 2.819 percent. (Additional reporting by Aiko Hayashi in Tokyo) (Editing by Kazunori Takada
