TOKYO (Reuters) - Japan's current account surplus tumbled in August due to declining overseas profits and chronic trade deficits, raising questions about the nation's ability to rely on its status as a net creditor to ease the pain of its massive public debt pile.
The 63.7 percent annual decline in the current account surplus was the biggest in almost two years and confounded the median estimate for a 23.4 percent annual increase as the income surplus, which includes earnings from overseas subsidies, fell for the first time in nine months.
The income surplus decline could prove temporary as overseas economies remain stable. Trade deficits will be more persistent, though, as energy imports soar to make up for closed nuclear power plants, which will in turn weigh on the current account.
"We have to worry about Japan's debt dynamics in the long term," said Shuji Tonouchi, senior fixed income strategist at Mitsubishi UFJ Morgan Stanley Securities.
"Japan was a high surplus country, but things are changing. Other countries have also transitioned from maintaining a high surplus via exports only to watch their surplus shrink."
The current account surplus stood at 161.5 billion yen (1.03 billion pounds), versus the median forecast for a 549.0 billion yen surplus, finance ministry data showed on Tuesday.
The income surplus fell 10.0 percent in August from a year ago to 1.3 trillion yen.
Japan's public debt has just topped 1,000 trillion yen, or about $10 trillion. At more than twice Japan's GDP, it is the heaviest debt burden among industrialised nations.
Until a few years ago, some economists argued that Japan's debt burden is not much of a problem because its hefty current account surplus means it is a net creditor to the world.
However, the trade balance, which was already under pressure from a shift in production overseas, fell into deficit after the March 2011 earthquake and nuclear disaster as energy companies replaced nuclear energy with imported fossil fuels.
Since sweeping to power in December with a mandate to jump-start the world's third-biggest economy, Prime Minister Shinzo Abe has launched an aggressive policy mix of government stimulus and monetary easing dubbed 'Abenomics' that has driven the yen lower and buoyed the stock market.
Still, while a weakening yen has boosted the competitiveness of Japanese exporters and increased the value of overseas revenue in yen terms, it has also pushed up import costs.
In an effort to address the mounting debt problem, Abe this month agreed to raise the 5 percent sales tax to 8 percent in April to pay for rising welfare costs.
However, there are worries this will not make a sufficient dent in the debt burden because the government is also compiling stimulus spending that will wipe out much of the gain in tax revenue.
