* Japan megabanks have $44 bln in Fannie/Freddie debt-report

HONG KONG, July 15 (Reuters) - Asian stocks fell to a two-year low on Tuesday as investor confidence waned in the region's financial sector, which faces high inflation, a stricter lending environment and massive volatility from overseas markets.
The U.S. dollar fell towards a record low against the euro as traders worried about the stability of the financial system despite the U.S. government's announcement on Sunday of an emergency plan to support two struggling top mortgage lenders.
Megabanks in Japan, Asia's richest economy, had roughly 4.7 trillion yen ($44.3 billion) in debt issued by U.S. mortgage lenders Fannie Mae and Freddie Mac, whose stock plummeted last week on fears about solvency, an article said on Tuesday, adding to worsening sentiment on equities. [
]Investors' willingness to take risks was further drained by a shift in focus from lending institutions that are believed to be too big to be allowed to fail, to ones that are small enough to collapse. Overnight the S&P U.S. financial sector index <.GSPF> fell to the lowest in nearly a decade.
Add to all that high oil prices and investors have increasingly abandoned stocks for the relative safety of assets like Japanese government bonds, whose benchmark 10-year yield hit a 2-month low.
"Sentiment is really fragile," said Louis Wong, research director with Phillip Securities in Hong Kong. "Investors are worried that there might be more bank failures, especially small banks in the United States. Whenever you have this kind of financial turmoil, banking stocks get hit."
Japan's Nikkei share average <
> fell 2 percent to the lowest since April 1.The country's biggest bank, Mitsubishi UFJ Financial Group <8306.T>, slid 4.8 percent and No. 2 Mizuho Financial Group <8411.T> declined 4.5 percent after the Nikkei business daily said those banks had some of the biggest exposure in Japan to debt issued by Fannie Mae <FNM.N> and Freddie Mac <FRE.N>.
BETTING AGAINST BANKS
Sentiment and risk apparently mattered more to investors than the likelihood of a company's bottom line suffering from direct exposure to bad debt.
Concern about the exposure was likely overdone, said Koichi Ogawa, chief portfolio manager at Daiwa SB Investments, pointing out that the debt is not "subprime" but backed by mortgages made to borrowers with strong credit.
"There is no problem with Fannie and Freddie debt. You are pretty much at the level of guarantee by the U.S. government."
Still, the MSCI pan-Asia equity index <.MIAS00000PUS> dropped 2.2 percent to the lowest since August 2006.
Hong Kong's Hang Seng <
> sank 3.5 percent, with HSBC <HSBA.L><0005.HK>, Europe's largest lender, one of the heaviest drags on the index for the second consecutive day.Chinese banks like China Construction Bank <0939.HK>, whose shares fell 5.1 percent and Industrial & Commercial Bank of China <1398.HK>, down 5.4 percent, were among the biggest percentage losers despite having been investor favourites a week ago.
Australia's benchmark index <
> tumbled 2.3 percent to a two-year low, weighed by shares of the country's top banks like Macquarie Group Ltd <MQG.AX>, down 6.2 percent, and Commonwealth Bank of Australia <CBA.AX>, down 3.3 percent."With inflation rising, you would expect central banks to raise rates, which will flatten out the yield curve -- and that means banks will not be so profitable here," said Mixo Das, equity strategist with Lehman Brothers in Hong Kong.
"Lending standards are tightening so banks are expected to lose money," he said.
Besides the dramatic exit from Fannie and Freddie assets in the last week, investors on Friday witnessed the fall of IndyMac Bancorp <IMB.N>, the third-largest bank failure in U.S. history.
PUMP UP THE VOLATILITY
Volatility, often the nemesis of portfolio managers, has been on the rise in the last few months, and indications of risk-taking have deteriorated.
Wall Street's so-called gauge of fear, the Chicago Board Options Exchange Volatility index <.VIX>, climbed to a four-month high on Monday, up for the fourth straight day.
Results forthcoming from JPMorgan Chase & Co <JPM.N>, Merrill Lynch & Co Inc <MER.N> and Bank of America Corp <BAC.N>, should offer some indication on what extent credit stress fallout is worsening.
Meanwhile, the so-called TED spread indicator of credit risk popped to the highest since May 1 overnight. The TED spread is the difference between 3-month U.S. inter-bank borrowing rates and the 3-month U.S. Treasury bill yield.
In such a risk-averse environment, government bonds have thrived. The benchmark Japanese 10-year yield <JP10YTN=JBTC>, which moves in the opposite direction of the price, was down five basis points at 1.53 percent, after hitting a three-month low of 1.535 percent.
The yield has fallen more than 35 basis points since it struck an 11-month peak of 1.895 percent in mid-June.
Many traders in the foreign exchange market were awaiting a speech from Federal Reserve Chairman Ben Bernanke later in the day, with some dealers pointing to instability in the financial sector as a reason for persistent dollar weakness.
The euro <EUR=> inched up 0.2 percent from late U.S. trade to $1.5941, not far from the record high of $1.6020 hit in April.
The dollar fell 0.3 percent to 105.82 yen <JPY=>.
Gold <XAU=> fell to $970.00/971.00 an ounce by midday from $971.20/972.20 in New York, but held within sight of its strongest level in almost four months as surging oil prices and financial market jitters boosted the metal's safe-haven appeal.
Oil <CLc1> eased 7 cents to $145.11 a barrel, but within sight of last week's record above $147, as dealers weighed the impact of high oil prices on global demand against fresh threats of supply disruptions in Nigeria, Brazil and Iran.
