Asian stock markets fell sharply on Thursday as persistent inflation worries and interest rate fears triggered a broad sell-off across the region. South Korea's KOSPI Composite Index (KRX:KOSPI) led the losses, sliding 2.62% to close at 6,625.93, representing its third consecutive day of declines. Japan's Nikkei 225 index dropped 1.42% to end at an intraday low of 69,042.11, while Hong Kong's Hang Seng Index (HSI:HSI) fell 1.43% to close at 23,785.79, slipping below the key 24,000 level.

The market downturn was driven by high oil prices, which have heightened inflation concerns, and signals from the U.S. Federal Reserve that borrowing costs may need to rise before the end of the year. This prompted heavy selling from foreign and institutional investors, particularly in the technology and financial sectors. Technology shares led the retreat in Seoul, where Samsung Electronics Co., Ltd. (005930) fell 2.42% and SK hynix Inc. (000660) slid 2.44%, despite Samsung projecting a third-quarter operating profit of 107.4 trillion won. In Hong Kong, financial giants HSBC Holdings plc (0005) and Standard Chartered plc (2888) fell 4.87% and 5.22%, respectively, while tech leader Tencent Holdings Ltd. (0700) shed 2.19%.

Investors are keeping a close eye on energy prices and upcoming central bank decisions to see if inflationary pressures will persist. Market players will also watch for the return of Taiwanese trading following the National Day holiday, after the Taiwan Semiconductor Manufacturing Co. (2330) fell 1.35% ahead of the break. Additionally, mainland Chinese markets will be scrutinized for signs of stabilization after the Shanghai Composite Index fell 0.79% to a two-month low upon reopening from the Golden Week holiday.
