TOKYO, May 21 (Reuters) - Japan's Nikkei stock average slid 2 percent to a one-week low on Wednesday, pressured by selling of Toyota Motor Co <7203.T> and other exporters as the yen advanced against the dollar on worries about inflation in the U.S. economy.
Financials slumped in tandem with their U.S. peers after a key U.S. analyst said the credit crisis was far from over. That came a day after Mitsubishi UFJ Financial Group <8306.T> forecast virtually no growth this year, though it posted a 71 percent rise in fourth-quarter profit as a turnaround in its consumer credit unit helped offset subprime losses.

"The whole issue of credit remains a problem, and even with a tax cut, U.S. consumption doesn't seem to be expanding. There's a lot of negativity about this looking ahead."
Two of the biggest U.S. retailers, Target Corp <TGT.N> and Home Depot Inc <HD.N> announced slack quarterly earnings, underscoring the problem.
Worries about the U.S. economy have grown after oil prices jumped and the U.S. Price Producer Index, excluding volatile food and energy costs, released on Tuesday, rose at the fastest since 1991 for the year to April. [

By midday, the dollar had slid to around 103.15 yen <JPY=>, pressuring exporters. A stronger yen makes Japanese goods less competitive overseas and eats into profits when brought home.

Japan's top three banks lost a total of 861 billion yen ($8.31 billion) on investments related to subprime U.S. mortgages in the year to March 2008, with the bulk of that coming from No.2 lender Mizuho Financial Group <8411.T>.

Insurers fared even worse, with Sompo Japan Insurance Inc <8755.T>, the No.2 non-life insurer, falling 6.2 percent to 1,074 yen while the top non-life insurer, Millea Holdings Inc <8766.T>, slid 4.9 percent.
