On Wednesday, September 10, 2025, major Asia-Pacific equity benchmarks posted gains as investors digested China’s August inflation figures. The data release, viewed as a key indicator of domestic demand and policy direction in the world’s second-largest economy, provided fresh momentum for regional risk assets despite ongoing local uncertainties.

Key performances included:

• Nikkei 225 (Japan) up 0.23%, with the Topix rising 0.12%, led by exporters and industrial names.

• S&P/ASX 200 (Australia) edged 0.13% higher, supported by resource and energy stocks.

• Hang Seng (Hong Kong) gained 0.4% in early trade, while the Hang Seng Tech Index advanced 0.59%, underscoring renewed appetite for Chinese technology equities.

• Kospi (South Korea) surged 1.42% to its highest level since late 2021, with the Kosdaq adding 0.53%.

• Jakarta Composite (Indonesia) rebounded 0.58% after three consecutive sessions of losses.

• Straits Times Index (Singapore) jumped 1% to a record high of 4,341.32.

Meanwhile, the Indonesian rupiah strengthened 0.21% to 16,435 against the U.S. dollar after a sharp 1% decline in the prior session, signaling a quick stabilization in investor sentiment.

China: Mixed Signals from Inflation Data

China’s August inflation report presented a two-sided picture:

• Consumer Price Index (CPI) fell 0.4% year-on-year, steeper than the expected decline of 0.2%, pointing to subdued domestic demand and persistent disinflationary pressure.

• Producer Price Index (PPI) dropped 2.9% year-on-year, in line with forecasts and improving from a 3.6% decline in July, suggesting that input cost deflation is easing in the industrial sector.

This divergence highlights a “half-bright, half-dark” scenario: while household consumption remains weak, the stabilization of factory-gate prices hints at gradual recovery in manufacturing profitability. Analysts believe this dynamic will likely prompt Beijing and the People’s Bank of China (PBoC) to maintain accommodative policies, though large-scale stimulus measures remain unlikely given debt constraints.

Technology Rally and the Apple Effect

Regional markets also responded to Apple’s product launch event on Tuesday, where the company unveiled its new iPhone, Apple Watch, and AirPods.

• Foxconn (Taiwan) gained 1.67%.

• Samsung Electronics (South Korea) advanced 1.82%, buoyed by optimism over chip and component demand.

Interestingly, Apple’s own shares closed 1.48% lower in the U.S., as investors remained cautious about revenue prospects. Nevertheless, Asian suppliers benefitted from expectations of stronger orders and a cyclical upswing in tech demand.

Notably, Alibaba Group (Hong Kong) rose 2.89%, marking its fourth consecutive session of gains and reaching a near four-year high. Momentum was driven by news that humanoid robotics startup X Square Robot raised $100 million in a funding round led by Alibaba Cloud. This underscores Alibaba’s strategic pivot toward AI and robotics, sectors poised to deliver high growth over the next decade.

South Korea: Stable Labor Market, Tech-Led Upside

South Korea’s seasonally adjusted unemployment rate ticked up slightly to 2.6% in August from 2.5% in July, indicating modest softening in the labor market. However, the level remains among the lowest in the OECD, alleviating concerns of broader weakness.

The Kospi’s strong rally was largely driven by technology heavyweights Samsung and SK Hynix, as global demand for AI chips and advanced semiconductors continues to strengthen. This reaffirms South Korea’s strategic role as a key beneficiary in the ongoing AI-driven technology cycle.

Indonesia and Singapore: Political Risk vs. Financial Stability

Indonesia’s equity market staged a rebound following a political shock earlier in the week, when President Prabowo Subianto unexpectedly dismissed Finance Minister Sri Mulyani Indrawati. Widely respected for her fiscal discipline, Indrawati’s removal rattled investor confidence, sending the Jakarta Composite down 1.78% in the prior session and the rupiah lower by more than 1%.

However, the swift recovery of both equities and the currency suggests that investor sentiment remains cautious but not deeply bearish.

In contrast, Singapore stood out as a regional safe haven, with the Straits Times Index hitting a record high. The strong performance reflects robust capital inflows and Singapore’s reputation as a stable financial hub amidst regional volatility.

Global Linkages: Fed Policy in Focus

Regional dynamics are increasingly tied to U.S. monetary policy. Investors are awaiting key U.S. inflation prints (CPI and PPI) later this week, ahead of the Federal Reserve’s September 17 meeting.

• A softer inflation reading would bolster expectations for a 25 basis point rate cut, with some market participants even pricing a slim chance (~7%) of a 50 basis point cut, potentially sparking a global “risk-on” rally.

• Conversely, if inflation surprises to the upside, the Fed could delay easing, triggering risk aversion and a pullback across Asian equities

Wednesday’s session highlighted the interplay of multiple forces: China’s deflationary pressures, Apple’s tech cycle ripple effects, Indonesia’s political volatility, and global monetary expectations. Overall, sentiment across Asia-Pacific remains constructive, anchored by the view that policymakers will prioritize growth support through accommodative measures.

That said, investors should closely monitor three critical variables:

1. China’s domestic demand – prolonged weakness could entrench deflationary risks.

2. Fed policy trajectory – September’s decision will be pivotal in shaping global capital flows for Q4.

3. Political stability in emerging markets – particularly Indonesia, where policy credibility remains a concern.

Against this backdrop, a prudent strategy is to maintain portfolio diversification, overweight quality technology and financial stocks, and stay tactically flexible in response to upcoming macro and policy signals.
