- Round-up of South Korean financial markets:

South Korean shares fell on Thursday as disappointing results from Oracle Corp. erased a rally spurred by the Federal Reserve's rate cut. The won weakened and the benchmark bond yield rose.

The benchmark KOSPI .KS11 closed down 24.38 points, or 0.59%, at 4,110.62.

Among index heavyweights, chipmaker Samsung Electronics 005930.KS fell 0.65% and peer SK Hynix 000660.KS lost 3.75%. Battery maker LG Energy Solution 373220.KS climbed 1.02%.

Hyundai Motor 005380.KS and sister automaker Kia Corp 000270.KS were down 2.31% and down 0.41%, respectively. Steelmaker POSCO Holdings 005490.KS shed 2.07%, while drugmaker Samsung BioLogics 207940.KS rose 0.24%.

Shares in Oracle ORCL.N opened almost 12% lower in Frankfurt, tracking U.S. after-hour losses after the company forecast sales and profit that missed analyst estimates. Oracle's performance is deeply tied to the AI boom.

The U.S. Federal Reserve cut interest rates on Wednesday in another divided vote, but signalled it will likely pause further reductions in borrowing costs as officials look for clearer signals about the direction of the job market and inflation that "remains somewhat elevated."

Of the total 928 traded issues, 551 shares advanced, while 327 declined.

Foreigners were net buyers of shares worth 346.1 billion won.

The won was quoted at 1,473.0 per dollar on the onshore settlement platform KRW=KFTC, 0.15% lower than its previous close at 1,470.8.

The KOSPI has risen 71.31% so far this year. The won has weakened 0.0% against the dollar so far this year.

In money and debt markets, December futures on three-year treasury bonds KTBc1 lost 0.04 points to 105.14.

The most liquid three-year Korean treasury bond yield KR3YT=RR rose by 0.6 basis points to 3.096%, while the benchmark 10-year yield KR10YT=RR rose by 0.9 basis points to 3.379%.
