Nikkei, uranium stocks plunge on Japan worries

Stock markets in Japan and across the globe plunged on Mondayas investors reacted to the ongoing consequences ofthedeadly earthquake and tsunami.

Japan's central bank injected 15 trillion yen ($178 billion Cdn) into money markets to stem worries about the world's third-largest economy. It alsoexpanded an asset buying fund byfive trillion yen to 40 trillion yen ($59 billion to $476 billion) as a step to support businesses.

By flooding the banking system with cash, the central bank hopesfinancial institutionswill continue to lend money and meet the likely surge in demand for post-earthquake funds.

Japan's economy has been ailing for 20 years, barely managing to eke out weak growth between slowdowns. It is saddled by a massive public debt that, at 200 per cent of gross domestic product, is the biggest among industrialized nations.

Eleven of the country's nuclear power stations have been shut down, and concern is mounting that the Fukushima Daiichi plant may be on the verge of a meltdown in the wake of Friday's quake. Fuel rods were reportedly melting down inside one of the reactor cores on Monday evening.

At the very least, it seems unlikely thatJapan's nuclear industry will ever return to its former size.

Those fears caused nuclear-related stocksto behit hard on North American stock exchanges. TSX-listed Cameco Corp. tankedas the market opened in Toronto, losing more than $8 or 22 per cent to $28.39, before reboundingto closeat$31.70.Denison Mines was also down sharply, shedding 76 cents, or 23 per cent, to $2.43within minutes of opening, and staying around that level through the trading session to close at $2.48. Uranium One Inc. was also down28per cent to $4.31.

The benchmark Nikkei 225 stock average shed nearly 634 points, or 6.2 per cent, to 9,620.49, extending losses from Friday and wiping out all the gains for this year. It was the Japanese stock market's worst day since the 2008 financial crisis.

Shares of Tokyo Electric Power Co. nose-dived more than 23 per cent as it struggled with malfunctioning nuclear reactors and a power shortage that led the company to warn it may need to ration electricity.

Companies with nuclear power-related businesses registered staggering losses, including Hitachi Ltd., down 16.2 per cent, and Toshiba Corp., down 16.3 per cent. Mitsubishi Heavy Industries slumped 10 per cent and Kobe Steel Ltd. skidded 6.4 per cent.

Other Asian markets were off, but just a fraction of the losses in Tokyo. The Hang Seng index in Hong Kong fell and Singapore's Straits Times index were both down about 0.5 per cent.

In Europe, Britain's FTSE 100 was down 0.9 per cent at 5,775.24 while Germany's DAX slid 1.7 per cent to 6,866.63. France's CAC-40 was 1.3 per cent lower at 3,878.04.

Overall, the North American markets were also lower, with the TSX/S&P Composite Index down55.06 pointsto13,619.19. The Dow Jones Industrial Averagelost51.24 pointsto close at11,993.16 in New York.

Infrastructural damage feared

Oil prices dropped below $99 a barrel before recovering, with the disaster threatening to send Japan, the world's third-largest economy, into a recession that could crimp demand for crude. There is concern that widespread infrastructural damage may cripple factory output, a worry the central bank echoed Monday.

Benchmark crude for April delivery closed upthree cents USat $101.19 a barrelon the New York Mercantile Exchange. The contract lost $1.54on Friday.

The tsunami and earthquake that hit Japan on Friday about the time the market closed has killed about 2,800 people, but the death toll may be as high as more than 10,000. It hasdisrupted transportation in the northeastern part of the country, and has severely damaged several nuclear plants.

The electricity shortage caused by the damage has forced leading Japanese car companies Toyota, Honda and Nissan to close for an indefinite period, and electricity companies are warning of rotating blackouts on Monday to conserve power.

The 1995 earthquake that devastated Kobe cost $132 billion US, said Sheila Smith, an expert in Japan Studies at the Council on Foreign Relations, a U.S. think-tank.
