HONG KONG, Jan 10 (Reuters) - Fears that debt-ridden Portugal may have to seek government aid kept the euro near a four-month low and appetite for risky assets weak, although a rebound in oil prices helped energy shares in Asia.
Portugal, also scheduled to sell 1.25 billion euros of debt on Wednesday, is expected to pay a high price to tap capital markets. Spain and Italy will also come to market in what is seen as the year's first major test of whether the euro zone's higher risk countries can finance their huge debt piles at sustainable cost. [
]A senior euro zone source told Reuters on Sunday that pressure was growing on Portugal from Germany and France to seek financial help from the EU and IMF to stop the bloc's debt crisis from spreading. [
]The euro zone pressures though were unlikely to dispel a trend seen in the new year for an increased willingness to take risks.
"The year started out on a fairly bullish note and what we're seeing is some caution out there," said Lorraine Tan, director for equity research for Asia at Standard & Poor's in Singapore.
"Whenever there's going to be a government bond auction in Europe, its going to create some anxiety in the markets and I think that's going to be a characteristic of this year," she said.
The euro fell to lows not seen since mid-September, slipping as low as $1.2860 on trading platform EBS before clawing back to around $1.2900.
Asian stocks were slightly lower on Monday with trading volumes light as Japanese markets were closed for a public holiday. The MSCI Asia Pacific ex-Japan index fell 0.5 percent with energy stocks outperforming on oil's rebound.
Volatility was increasing in some markets with a history of vulnerability to inflation, such as Indonesia, Asia's top performing major equity market in 2010.
Indonesia's main stock index fell around 5 percent as foreign investors continued dumping shares of banks on concerns that the country's central bank was behind the curve on inflation and would probably have to catch up. [
]"I think some foreign investors were not too comfortable with the central bank not raising interest rates despite high inflation," said Ferry Wong, head of Indonesia research at Macquarie Securities in Jakarta.
OIL BOUNCES
In commodity markets, U.S. crude oil <CLc1> rose towards $89 a barrel, bouncing back from last week's 3.2 percent dip, after a leak shut an Alaskan pipeline that carries 12 percent of the U.S. crude output.
The Trans Alaska Pipeline was shut down on Saturday with no indication of when it would reopen after a leak discovered at Prudhoe Bay, forcing oil companies to cut output to 5 percent of their daily average of 630,000 barrels. [
]Earnings season for major U.S. corporations kicks off later on Monday with major industrials, big oil, banks and chipmakers scheduled to report quarterly numbers.
Aluminum producer Alcoa , scheduled to report later on Monday, is expected to post a strong fourth-quarter profit amid signs that a growing global economy is pushing up demand for aluminum and driving up the metal's price.
Analysts, on average, have raised their forecast for Alcoa's 2011 earnings per share 3.7 percent in the past seven days, according the Thomson Reuters Starmine. (Editing by Kevin Plumberg)
