Japan Stocks Jump on Treasury Bailout; Mitsubishi Gains on Oil

While European and American financial titans have teetered and collapsed, Japan’s giant banking groups have stood relatively unscathed. The growing global credit crisis, which threatens companies and consumers elsewhere, has yet to appear here, where the problem for years has been that the nation’s banks have too much cash, not too little. And while the United States Federal Reserve seems to be shoring up the entire American financial sector, the last time this central bank intervened in markets, it did so in dollars instead of yen — to help international markets.

Economists and bankers say Japan is able to keep itself apart for a very simple reason: it has enough cash to finance its own needs.

The country sits on a $14 trillion pile of household savings, the product of decades of trade surpluses and frugal lifestyles. This has allowed Japan to finance its immense $8.1 trillion fiscal deficit and still have enough money left over to be the world’s largest creditor nation for the last 17 years.
