HONG KONG, June 23 (Reuters) - Asian stocks tumbled to multi-month lows on Monday amid fears that more bad news could be lurking in the global financial sector, but oil prices held steady above $135 a barrel after Saudi Arabia said it was ready to increase output.
Inflation remains a major concern. World energy powers met for an emergency session at the weekend in Jeddah, Saudi Arabia, but had no quick fix to crude prices that have doubled over the past year. [
]The prevailing uncertainty kept the dollar range-bound, but lifted most Asian bonds. Investors were also on hold for the U.S. Federal Reserve's policy setting meeting that begins on Tuesday and could give further clues as to U.S. interest rates.
"There are worries about additional mortgage-related losses at U.S. financial institutions," said Kenichi Hirano, operating officer at Tachibana Securities in Tokyo.
The MSCI index of Asian stocks outside Japan <.MIAPJ0000PUS> fell more than 1 percent, hitting its lowest since March 25. The index has fallen for five straight weeks and is down more than 17 percent this year.
The losses follow a weak session in Wall Street on Friday as expectations that U.S. financial firms will need to raise more capital triggered a guessing game about who will be next.
Global lenders remain under pressure, with Citigroup <C.N>, the largest U.S. bank, set to slash 6,500 jobs in its investment bank division, according to the Wall Street Journal. [
]The financial crisis has set into motion more U.S. regulatory scrutiny. According to another Wall Street Journal article, the Fed and the U.S. Securities Exchange Commission are finalising an agreement to start the process of redrawing how Wall Street is regulated. [
]A global financial sector struggling to come to grips with the effects of a credit crunch has been accompanied by the spectre of rising inflation as food and energy costs surge.

U.S. crude futures <CLc1> edged up 30 cents to $135.66 a barrel as tensions between Israel and Iran and a weak dollar continue to bolster prices that gained nearly $3 on Friday.
But Saudi Arabia's willingness to increase oil output and a ceasefire announced by Nigerian militants contributing to cap broader gains.
"The market has taken profits on comments by Saudi Arabia it will raise production ... but there are many other factors at play, which has in some ways offset the news from Jeddah," said Mark Pervan, a senior commodities analyst at Australia and New Zealand Bank in Melbourne.
Meanwhile, the dollar was little changed from late U.S. trading on Friday at 107.31 yen <JPY=>, or well below a 4-month high of 108.59 yen hit last week.
The euro edged up 0.1 percent to $1.5624 <EUR=>, supported by expectations that the European Central Bank will raise interest rates by a quarter percentage point to 4.25 percent in July.
On the other hand, U.S. interest rates are widely expected to be kept steady at 2 percent this week, though investors will focus primarily on the central bank's statement.
Most Asian bonds gained as investors sought safety from the stock losses, but an exception was South Korea, where government debt tumbled on a newspaper report the Bank of Korea was planning to raise reserve requirements to curb hefty money supply growth, though the central bank denied this. [

Gold <XAU=> rose about $3 an ounce to above $904.
