Asian markets staged a broad recovery on September 18, 2026, reversing the mixed performance of the previous session. South Korea led the advance, followed by Japan and mainland China, while Hong Kong and the Australian and Japanese currency indexes also moved higher. The session brought renewed momentum to several benchmarks that had remained under pressure throughout the middle of September.

South Korea Leads the Regional Rebound

The KOSPI Composite Index was the strongest reported market, rising 2.66% to 6,894.23. The sharp gain followed a virtually flat session on September 17 and pushed the benchmark close to the 6,900 level.

The move represents a significant recovery from the recent selloff that had taken the KOSPI below 6,700. However, the index remains below 7,000, leaving that level as an important reference point for the next phase of trading.

Japan Returns Above 65,000

The Nikkei 225 gained 1.38% to 65,018.95, moving back above the 65,000 level after rising 0.33% in the previous session. The benchmark has now recovered from its move toward 63,000 earlier in the week.

The Japanese Yen Index also edged higher, gaining 0.16% to 64.11. The move was modest compared with the yen’s earlier September volatility, but it marked a stabilization after the currency index declined 0.69% on September 17.

China and Hong Kong Recover

The SSE Composite Index advanced 0.94% to 3,911.87, moving back above 3,900 after falling to 3,875.60 in the previous session. The benchmark remains below 4,000 but has regained some of the ground lost during the recent decline.

The Hang Seng rose 0.60% to 24,750.78, extending its 0.44% decline from September 17 into a modest recovery. The index remains below 25,000, keeping that psychological threshold in focus as investors assess whether the rebound can continue.

Australian Equities Hold Steady

The S&P/ASX 200 was virtually unchanged, slipping just 0.01% to 8,731.20. The benchmark had gained 0.41% in the previous session and remains above 8,700 despite the broader volatility.

The Australian Dollar Index gained 0.36% to 71.13, recovering from its 0.59% decline on September 17. The move provided additional stability in Australian markets even as the local equity benchmark paused.

India Remains Flat

The S&P BSE SENSEX declined just 0.03% to 74,294.96, making it the weakest-performing equity market alongside the nearly unchanged ASX 200. The benchmark remained below 75,000 and has shown limited movement over the past several sessions.

The lack of a significant move in the Sensex contrasts with the stronger recovery across South Korea, Japan and China, leaving India’s benchmark in a period of consolidation.

Outlook

The September 18 session marks a meaningful improvement in regional equity-market momentum, with six of eight reported indicators advancing. The KOSPI’s approach to 6,900, the Nikkei’s return above 65,000 and the SSE Composite’s move above 3,900 provide important near-term reference points. The Hang Seng remains below 25,000, while the Sensex continues to trade below 75,000 and the ASX 200 near 8,700. Investors will be watching whether the latest gains can develop into a broader stabilization across the region.
