SEOUL, December 11 (AJP) - Asian markets slipped or traded flat on Thursday as investors braced for a potential Bank of Japan interest rate hike and a broader unwinding of the yen carry trade.

The U.S. Federal Reserve’s earlier rate cut offered limited support, with sentiment pressured further after the Fed signaled a more hawkish policy outlook that tempered hopes for additional easing.

The Korean won weakened to 1,472.4 per dollar as of 4:40 p.m., down 5.8 won, amid expectations that capital could shift toward Japan should rates rise there.

South Korean government bond yields were mixed. The three-year yield edged up 0.6 basis points to 3.101 percent, while the 10-year yield slipped 0.7 basis points to 3.378 percent, with both remaining above the 3 percent level.

The benchmark KOSPI finished 0.59 percent lower at 4,110.62. Institutional investors drove the decline with net sales of 776.6 billion won ($520 million). Foreign investors purchased 347.2 billion won, while retail investors bought 408.8 billion won.

Chipmakers led the downturn. SK hynix fell 3.75 percent to 565,000 won, while Samsung Electronics eased 0.65 percent to 107,300 won. Export-oriented names were also dragged lower: Hyundai Motor, typically a beneficiary of a weaker won, closed 2.31 percent down at 295,500 won.

The day’s most active theme centered on redevelopment prospects for the Seoul Express Bus Terminal. Shinsegae climbed 4.28 percent to 256,000 won, while Dongyang Express surged 30 percent to 60,900 won and Chunil Express jumped 26.56 percent to 457,500 won.

The tech-heavy KOSDAQ ended virtually unchanged at 934.64.

Japan’s Nikkei 225 dropped 0.9 percent to 50,148.82 as renewed expectations of a BOJ rate increase pressured exporters and raised speculation that Prime Minister Sanae Takaichi’s stimulus plans may be put on hold.

Heavy industry stocks led losses, with Mitsubishi Heavy Industries plunging 4.59 percent to 4,050 yen ($26). Automakers fared better on views they were already undervalued: Toyota dipped 0.19 percent to 3,110 yen and Honda slipped 0.22 percent to 1,572 yen.

Semiconductor stocks were mixed. Advantest jumped 4.42 percent to 21,040 yen, while Tokyo Electron fell 1.57 percent to 32,600 yen.

Taiwan’s TAIEX retreated 1.32 percent to 28,024.75, dragged down by chipmakers. TSMC lost 2.33 percent to 1,470 Taiwan dollars ($47), and MediaTek tumbled 4.45 percent to 1,395 Taiwan dollars, breaking below the NT$1,400 mark.

Mainland Chinese markets also weakened on concerns about yen carry trade unwinding. The Shanghai Composite slipped 0.7 percent to 3,873.32, while the Shenzhen Component dropped 1.27percent to 13,147.39.

Hong Kong’s Hang Seng Index was little changed at 25,530. Early gains evaporated on fears of capital outflows, but the index’s U.S. dollar peg and expectations that the Fed’s rate cut would ease valuation pressure helped limit losses.
