SEOUL, Oct 7 (Reuters) - South Korea's president dismissed talk of a repeat of the currency crisis that nearly broke the economy 10 years ago, trying to calm investors as the won hit a 7-1/2-year low on fears global financial turmoil might drag down the country's banks.

But in a sign of mounting concern, top economic ministers and the head of the central bank met to discuss the financial upheaval that began with the U.S. housing market and now threatens lenders around the world, with those in South Korea joining the ranks of those seen as most vulnerable.

President Lee Myung-bak has already called for a summit with China and Japan on the crisis and his finance minister has urged local banks to sell foreign assets to raise the dollars that other banks were unwilling to lend them. [ID:nSEO335854]

"The current crisis situation is different from that in 1997," Yonhap news agency quoted Lee as saying during a scheduled cabinet meeting.

"We don't have to be overly optimistic, we don't need to be pessimistic and caught up in a fear of crisis," said Lee.

South Korea only escaped sovereign default in the 1997/98 Asian financial crisis with an international rescue package worth close to $60 billion led by the International Monetary Fund.

An official at Kookmin Bank 060000.KS, the country's top lender, said a dollar shortage in the local market was not as severe as the market feared.

But he added: "If current global liquidity problems continue, it could hit the corporate sector as banks will rein in lending to the sector due to dollar shortages."

In one move to counter the foreign currency squeeze, state-run Korea Development Bank (KDB) said it planned to borrow up to $4 billion by the end of the year.

Concerns over South Korea's financial sector mounted this week as the country said its banks were having trouble raising foreign currency funds, with foreign capital fleeing the country.

Standard & Poor's Ratings Services said on Tuesday pressure from the global liquidity squeeze threatened to negatively affect the credit quality of Korean banks, mainly due to their ongoing foreign currency funding needs. [ID:nWLB2080]

Banks' foreign currency funding has more than doubled to $127 billion as of end-June 2008 since the end of 2005, it said.
