HONG KONG, March 14 (Reuters) - Asian stocks outside Japan edged up on Monday, with demand for commodity-related shares offsetting the steep drop in Japanese markets following a massive earthquake and tsunami.
Construction and refinery shares across the region saw healthy demand on hopes of bigger profits because of large-scale recontruction efforts as the country battled to prevent a nuclear catastrophe after the natural disasters that may have killed more than 10,000 people.
Seoul shares reversed early losses to turn positive, helped by solid gains in technology and automaker counters following news of production disruption by its Japanese peers while stocks in Taiwan trimmed early falls.
"Tourism, shipping and insurance firms will clearly be hit by shrinking demand from Japan," said Yu Rayming, chief investor officer of Prudential Financial.
"However, the downside for the overall stock market would be limited. Demand for oil refining, steel and cement issues will rise due to rebuilding after the quake," he said, adding his firm's funds bought these shares today.
But heavy losses in Japanese stocks and concerns over developments in the country's damaged nuclear reactors prompted investors to stay largely sidelined with safe haven themes such as weaker stocks and higher gold likely to dominate in the near term. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Nuclear incident scale: http://r.reuters.com/cag58r Map of reactors: http://r.reuters.com/dyf58r Story on Japan Markets SPECIAL REPORT-Can Japan find "New Deal"? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^
"There are some investors buying on dips but overall sentiment is still cautious especially with the nuclear developments so we might see more volatility this week," Frances Cheung, Asia-ex Japan strategist at Credit Agricole CIB said referring to efforts by authorities to stem a broader fallout.
That spilled over to the rest of the region with Korean nuclear power plant designer KEPCO down sharply while shares in Australia's uranium miners slid as questions rose on the near-term outlook of the industry.
The broader MSCI index of Asia-Pacific shares outside Japan was up 0.2 percent after falling nearly 3 percent last week.
Japan's Nikkei share average closed down 6.2 percent , the biggest single-day decline in two years, to the lowest since November 2010.
TREASURIES WARY
U.S. yields nursed losses after Friday's spike but investors grew wary of further selling pressure from Japanese insurers who may sell some of their most liquid foreign assets such as U.S. debt so they can respond to the earthquake.
Japan is the second-biggest holder of U.S. government debt.
Benchmark 10-year note yields were at 3.39 percent, up from 3.36 percent late on Thursday.
Brent crude fell nearly $2 to below $112 per barrel after Libyan leader Muammar Gaddafi regained control of some territory over the weekend in the country's civil war.
Wheat, corn and soy futures weakened as the quake exacerbated an already-bearish mood circulating across agricultural commodity markets in the past few weeks. Since mid-Feb, the December 2011 CBOT wheat contract has fallen 18 percent.
However, massive reconstruction expectations pushed copper prices above a three-month low hit on Friday.
In currency markets, the dollar rebounded from record lows versus the yen after the Bank of Japan injected 7 trillion yen into the money market to help ease nervousness, raising concerns that authorities might intervene to check sharp gains.
Gold advanced by one percent nearing a record high of $1,444.40 hit last week. (Additional reporting by Clement Tan and Faith Hung in TAIPEI; Editing by Kevin Plumberg)
