Global markets mostly fell Tuesday as investors worried about the global growth outlook and Spain's apparent delay in accepting a financial aid package.
Spain's markets have improved in recent weeks on expectations that the government will get some form of rescue loan from the 16 other eurozone countries. But Madrid has not made any formal request yet, likely wary of the policy conditions that would come attached.
The delay pushed the country's bond yields sharply higher on Monday, suggesting an increase in investor concern about the government's finances. The yields eased back somewhat on Tuesday after a bond auction was well-received. The sale of 12- and 18-month debt saw strong demand and resulted in lower interest rates than in the previous such auctions.
The auction result helped markets, but tensions remained — by midafternoon in Europe, Spain's main stock index was still down 1.4 percent.
"Investors appear to be turning nervous," said Kintai Cheung, analyst at Credit Agricole CIB.
Analysts say the stock losses are also a pull-back from highs hit last week, when the U.S. Federal Reserve triggered a market rally with the announcement of new stimulus measures. Faced with a struggling recovery in the world's biggest economy, the Fed announced plans to buy $40 billion of mortgage bonds a month for as long as necessary as part of a strategy to boost borrowing and spending. The Fed also extended its pledge to keep short-term interest rates low until 2015, a year longer than its previous target.
The size of the program buoyed confidence in the global economy, and stocks rallied. Since then, however, investors have begun to re-examine the big picture and to see substantial headwinds on the horizon.
"I think the outlook in the near term for the global economy is still fairly negative," said Peter Elston, strategist at Aberdeen Asset Management in Singapore. "I suspect that further weakness is just around the corner, which might explain the greater than expected easing by the Fed."
Losses began earlier in the day in Asia. Japan's benchmark Nikkei 225 index fell 0.4 percent to 9,123.77. Hong Kong's Hang Seng lost 0.3 percent to 20,601.93 and Australia's S&P ASX/200 fell 0.2 percent to 4,394.70.
Bucking the trend was South Korea's Kospi, which gained 0.1 percent to 2,004.96.
Benchmark oil for October delivery was down 61 cents to $95.98 per barrel in electronic trading on the New York Mercantile Exchange. The contract fell $2.38, or 2.4 percent, to finish at $96.62 a barrel on the Nymex on Monday, when trading was marked by huge volatility.
In currencies, the euro fell slightly to $1.3047 from $1.3107. The dollar fell to 78.58 yen from 78.74 yen.
