SEOUL South Korean exports tumbled for the first 20 days of March and producer inflation eased last month, data showed on Tuesday, reinforcing expectations the central bank will not raise interest rates further amid current market turbulence.

Asia's fourth-largest economy contracted last quarter for the first time in 2-1/2 years hurt by a slowdown in global demand for its exports and high household debt.

The country's shipments for the first 20 days of March fell 17.4% from the comparable period of last year, even though there was one more working day this year, led by a whopping 36.2% dive in sales to China, customs agency data showed.

Bank of Korea data earlier in the day showed the producer price index (PPI) in February was 4.8% higher than a year earlier, with the pace of increase slowing for an eighth consecutive month.

Economists said these figures confirmed the broad market expectations for weakening economic growth and easing inflation, raising more doubts about the central bank's tightening stance.

"Inflation will continue to slow and the economic growth will be so-so in the future, and now the overseas banking sector crisis will eventually have an impact here," said Moon Hong-cheol, economist at DB Financial Investment.

South Korea's central bank kept the policy interest rate unchanged at its last meeting on Feb 23, ending a year of uninterrupted rate increases to fight inflation. It next meets on April 11.

The liquidity troubles at US and European banks have sharply increased the volatility in financial markets, and South Korea is also worried about the indirect effects from the turmoil.

"The government is closely watching the situation, as volatility in global markets has increased in relation to the failure of Silicon Valley Bank and the liquidity crisis at Credit Suisse," Minister for Trade Ahn Duk-geun said while presiding over a meeting on exports.
