The International Monetary Fund is conducting "stress tests" on Japanese banks to gauge how vulnerable they are to a potential drop in the value of their huge holdings of Japanese government bonds, people familiar with the matter said. The move could sharpen investors' focus on the risk to Japan's economy from its ballooning debt, The Wall Street Journal reported.

Japan Airlines plans to raise more than 500 billion yen ($6.5 billion) ahead of re-listing its shares as early as September, a source with knowledge of the matter said, marking a sharp turnaround for the carrier following its bankruptcy in 2010, Reuters reported.

Japan's ruling party compromised on a plan to double the sales tax by 2015 to help reduce the world’s largest public debt, delaying implementation by six months to help lawmakers meet a campaign pledge, Bloomberg News reported yesterday. The proposal by Japanese Prime Minister Yoshihiko Noda would raise the sales tax from 5 percent to 8 percent in April 2014 and to 10 percent in October 2015. The agreement, reached late yesterday, must be approved by a government panel led by Finance Minister Jun Azumi before discussion with the opposition.

The Japanese government told the operator of the ravaged Fukushima Daiichi nuclear power plant yesterday to consider accepting temporary state control in return for a much-needed injection of public funds, in effect proposing an interim nationalization of the struggling utility, the New York Times reported yesterday.

Japan's Financial Services Agency (FSA) said that it will hire 32 officials to help tighten oversight of illegal trading at securities firms and other regulations as it boosts its headcount and budget for next year, Bloomberg News reported yesterday. The regulator plans to increase its net headcount to 1,548 people in 2012, the most in at least in five years, as its budget grows by 4.1 percent to 23.1 billion yen ($296 million), the agency said. The FSA penalized at least 35 financial institutions this year, including Citigroup Inc. and UBS AG, for breaching Japanese securities rules.

The Japanese and Indian governments agreed Wednesday to set up a three-year, $15 billion bilateral-currency swap line in an effort to buttress their economies against Europe's sovereign debt crisis, the Wall Street Journal reported Wednesday. The new swap line - five times that of the previous arrangement that expired in early summer - follows a Japan-South Korea deal in October to boost their bilateral swap pact to $70 billion from $13 billion. The moves signal spreading doubts among Asian economic powerhouses about the ability of European leaders to fix their problems anytime soon.

The world's major central banks acted jointly on Wednesday to provide cheaper dollar funding to European banks facing a credit crunch as the euro zone's debt crisis drove EU ministers to urge more IMF help to avert financial disaster, Reuters reported.

Tokyo Electric Power (Tepco), operator of the Japanese nuclear plant destroyed by the tsunami in March, forecast a second year of heavy financial losses even as it secured Y890bn (US$11.4bn) in government aid to help compensate victims of the nuclear disaster, the Financial Times reported. The utility on Friday projected a Y600bn net loss for the year to March 2012, its first earnings guidance since the triple meltdown occurred at its Fukushima Daiichi facility. If the estimate is realised, it would bring its losses since the tsunami to Y1,847bn.

Failed Japanese lender Takefuji said on Monday its debt holders approved a court-led rehabilitation plan, overcoming opposition from a group of overseas creditors who had sought liquidation of the company in hopes of achieving higher repayment rates, Reuters reported. Approval had been expected for the restructuring plan proposed by Takefuji, which filed for bankruptcy in September 2010, although the conflict with foreign creditors had attracted attention in Japan where such disagreements are rare.
