Market Overview

APAC markets presented a mixed picture as investors processed significant central bank developments and shifting risk sentiment. The Reserve Bank of Australia (RBA) adopted an unexpectedly hawkish tone, prompting market participants to sharply increase bets on an imminent Australian interest rate hike. This overshadowed the Bank of Japan’s (BOJ) widely anticipated policy rate increase and a tech-led rebound that bolstered sentiment across Asia. Oil prices also fell, easing broader inflation concerns, although geopolitical tensions in the Middle East continued to be a factor.

Markets

Australia’s benchmark S&P/ASX 200 (^AXJO) closed flat at 8,731.20, down 0.01%, extending its weekly loss to 0.11% and marking a third consecutive week of declines. Japan’s Nikkei 225 (^N225) ended the day up 1.38% at 65,018.95, while South Korea’s KOSPI (^KS11) surged 2.66% to close at 6,894.23. In China, the Shanghai Composite (000001.SS) closed up 1.00% at 3,914.35, and Hong Kong’s Hang Seng (^HSI) traded at 24,813.89, up 0.85% in active trading.

In commodity markets, international benchmark Brent Crude (BZ=F) traded at $102.83, down 1.90%, and WTI Crude (CL=F) was down 1.77% at $100.11. Bond markets saw a decline in yields, with the US 10-Year Treasury (^TNX) yield standing at 4.947%, a move of -5.90 basis points, following a nine basis point fall overnight to 4.93%, according to Investing.com.

What Drove Markets

Australian Monetary Policy Shift: The Reserve Bank of Australia’s hawkish turn was a key driver for local markets after Governor Michele Bullock warned the House of Representatives economics committee that upside risks to inflation were materializing and that the board would consider whether the three interest rate increases already delivered this year were enough to return inflation to target within a reasonable timeframe. This prompted traders to significantly step up bets on a looming interest rate increase, with Westpac, RBC, and UBS bringing forward their rate hike forecasts to September. The prospect of higher interest rates weighed on Australia’s largest mortgage lenders.

Bank of Japan Tightening: The Bank of Japan raised its policy rate by 25 basis points to 1.25%, marking its highest level since 1995. While widely expected, this move signaled a quicker pace in the BOJ’s normalization cycle. Governor Kazuo Ueda indicated the central bank remains prepared for further rate adjustments, despite a 7-2 split vote, with dissenters seen as tempering the message on future tightening. Japan’s core inflation slowed to 1.7% in August from 1.8% in July.

Oil Price Retreat and Geopolitical Dynamics: Oil prices fell, easing inflation concerns, as investors weighed hopes for additional Saudi crude supply against fresh Houthi strikes. Reports suggested Saudi Arabia is seeking to restore about half the capacity of its East-West pipeline, and China has asked Iran to help rein in Yemen’s Iran-backed Houthis, potentially alleviating supply disruptions around the Bab el-Mandeb Strait, despite fresh Saudi-Houthi attacks across their border on Thursday.

Asian Tech Rebound: Following a positive session on Wall Street where technology stocks rallied, Asian chip and AI-related shares saw significant gains. The previous US session saw the Nasdaq Composite (^IXIC) jump 1.69% to 26,418.30. Investors appeared to look past the prospect of a “higher-for-longer” rate environment, refocusing on the artificial intelligence growth story that continued to bolster corporate profits. Brian Levitt, chief global market strategist at Invesco, suggested that the current market cycle is unlikely to conclude due to higher Fed funds rates or oil prices, but rather when the artificial intelligence trade experiences a significant disruption. JPMorgan stated that investors “should be cautious,” and Corporate America is “embracing cash preservation.”

Stocks to Watch

Australia’s S&P/ASX 200 (^AXJO) finished flat. Index heavyweights BHP Group (BHP.AX) gained 1.40% to 61.05 and Rio Tinto (RIO.AX) rose 0.84% to 167.49, tracking stronger prices of iron ore and copper. Conversely, major mortgage lenders saw declines due to the prospect of higher interest rates, with CBA (CBA.AX) down 1.03% to 152.43, NAB (NAB.AX) dropping 1.91% to 38.47, Westpac (WBC.AX) losing 0.23% to 34.75, and ANZ (ANZ.AX) falling 0.26% to 37.68. Energy stock Woodside (WDS.AX) declined 1.70% to 32.42 amid lower oil prices.

In Japan, SoftBank (9984.T) led the market higher, gaining 1.09% to 6,315.00 on AI-related optimism. South Korean chipmakers also saw significant gains, with SK Hynix (000660.KS) up 6.42% to 1,857,000.00 and Samsung (005930.KS) rising 3.37% to 261,000.00.
