Tokyo - Asian shares fell on Wednesday on worries that the global economic slowdown will erode corporate earnings, with the market unconvinced the eurozone can decisively bring down struggling member states' borrowing costs even after yields pulled back.
The eurozone's three-year debt crisis, which began with its peripheral members, has engulfed the region's larger economies Spain and Italy. In a sign of sustained tension, Rome said on Tuesday that it may want to tap eurozone aid to ease its borrowing costs as market jitters persisted.
European stocks were likely to drop, with financial spreadbetters calling the main indexes in London, Paris and Frankfurt to open down as much as 0.7%. US stock futures held steady.
MSCI's broadest index of Asia-Pacific shares outside Japan was down 0.2%, after slipping to a new low for the month in the wake of a four-day losing streak in US stocks. Japan's Nikkei average shed 0.5%.
"There is a sore lack of momentum in the market," said Chung Seung-jae, an analyst at Mirae Asset Securities, referring to the Korean equities market, which fell 0.2%.
"In addition to pressure stemming from global growth worries, we have disappointing corporate earnings."
Hopes for more investment to spur growth helped to limit losses in China and Hong Kong shares. Premier Wen Jiabao said in comments published on the government's website on Tuesday that China must maintain reasonable investment growth to stand up to the headwinds from global economic uncertainties.
"We are still awaiting more details on how Beijing plans to push infrastructure investment which will give greater clarity on profitability for that sector, but otherwise sentiment remains quite weak," said Jackson Wong, Tanrich Securities vice-president for equity sales.
The notion that Europe was moving towards putting its rescue fund into action and Spain was set to receive the first batch of aid for its troubled banks by the end of July buoyed European shares and lowered Spanish and Italian yields on Tuesday.
But a hearing by the German Constitutional Court into whether the eurozone's bailout fund, known as the European Stability Mechanism, and planned changes to the region's budget rules are compatible with German law renewed fears of a protracted struggle to resolve the debt crisis.
The euro last traded at $1.2256, pinned near a two-year low of $1.2225 hit in early Monday Asian trade.
The ESM is a crucial tool in helping to bring down borrowing costs of indebted nations and breaking the link between the sovereign debt problem and the banking sector stress in Europe.
"Investors have grown sceptical about the decision-making process in Europe and this has hurt euro sentiment," said Andrew Wilkinson, chief economic strategist at Miller Tabak & Co in New York.
JGBS draw interest
With risk aversion deeply rooted in the markets, investors were pouring money into safer assets such as bonds issued by sturdier eurozone economies, including the Netherlands and France, as well as by Japan and international organisations, said a portfolio manager at a Japanese insurance company.
"Money, seeking places to park, is finding its way into sovereign debt, especially Japanese government bonds," he said.
"JGBs are not cheap in absolute terms but still look valuable relative to US Treasuries or German Bunds, given Japan's low inflation rate," he said, adding that the European Central Bank's cut in the deposit rate to zero could prompt eurozone banks to shift into safe haven bonds some of the €800bn they have parked at the ECB overnight.
Some money market traders have also said a probe into an interest rate-fixing scandal for Libor, or London interbank offered rate, could affect Tibor, the Tokyo interbank lending rate, which has traditionally been set high.
An easier interbank lending rate would push down rates on loans and provide incentives for banks to put their money to work in higher-yielding bonds, traders said.
The 10-year JGB yield fell to 0.785%, its lowest since June 2003.
Commodities and oil, which have recently been hurt by weak data from the United States and China, the world's biggest and second-biggest economies, regained their footing on Wednesday after sharp drops in the previous session.
China's second-quarter gross domestic product report due on Friday will likely show the slowest growth in at least three years, after this week's benign inflation and weak imports pointed to softening domestic demand while uncertainties over the external economic downturn clouded the prospect for exports.
Brent crude rose 0.5% to $98.48 a barrel and US crude added 0.8% to $84.57 a barrel.
Spot gold gained 0.4% to $1 573.91 an ounce but stayed firmly capped below $1 600, after posting its biggest one-day decline since late June on Tuesday as investors liquidated assets across the markets.
Gold holdings in the world's eight major exchange-traded products fell by the largest one-day amount since late May, shrinking by 116,427 ounces by the close on Monday to 70.529 million ounces, reflecting some of the investor wariness towards bullion.
Falling Spanish yields helped to improve sentiment in Asian credit markets, where the spread on the iTraxx Asia ex-Japan investment-grade index was 5 basis points narrower.
