* 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

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.
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 the government did not have plans to nationalise major banks at this stage, remarks that put to ease some worries that the largest U.S. banks may need to be taken over because of huge hits to their balance sheets from 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. [
]Data showed Japanese exports plunged a record 45.7 percent in January from the previous year, pointing to another sharp contract in economic activity in the first quarter of the year. [
]But Japanese shares were helped in part by reports that the government may start directly buying stocks to support the market and ease the strain on the country's big banks, whose large equity portfolios have suffered heavy 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.
Japan's Nikkei average <
> climbed 1.2 percent, holding off a 26-year low struck last October. The MSCI index of Asia-Pacific shares outside Japan <.MIAPJ0000PUS> was up 1 percent after hitting a three-month low earlier in the week.The gains lagged a 4 percent jump in the U.S. S&P 500 <.SPX> on a surge in financial shares.
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. [
]Analysts said there were also technical reasons for the gains in stocks and yen 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 its 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 97.20 before slipping back to 96.95 yen <JPY=>, up 0.3 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 was up $1.85 an ounce at $964.05 <XAU=> but has retreated from 11-month highs above $1,000 hit last week as some safe-haven buying has ebbed and investors booked profits.
Oil was little changed at $39.93 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 2.5 basis points to 1.290 percent <JP10YTN=JBTC> but has held in a tight range around 1.25 percent and 1.30 percent over the past two weeks. (Editing by Kim Coghill)
