Yesterday's Recap

Mainland China equities declined sharply on 23 September. The Shanghai Composite closed at 3,888.37, down 1.22 percent, while the CSI 300 fell 1.73 percent to 4,439.14. The moves coincided with PBoC statements on stepped-up counter-cyclical support and efforts to keep the yuan stable.

USD/CNY rose 0.06 percent to 6.70, with the central bank fixing the currency at 6.7468 against the dollar. Hong Kong’s Hang Seng Index declined 0.83 percent to 24,834.12, with USD/HKD holding steady at 7.84. In contrast, Taiwan’s TAIEX advanced 0.92 percent to 48,157.29.

No economic data releases were reported for mainland China, Hong Kong or Taiwan, leaving the August CPI reading of 0.80 percent year-on-year as the latest inflation benchmark. Copper rose 1.43 percent to 6.77, while Brent crude gained 3.83 percent to 107.03. Gold eased 0.19 percent to 4,310.10 and Bitcoin slipped 0.16 percent to 84,248.72.

The PBoC also announced plans to issue RMB bills through the HKMA to support the offshore yuan market. US-China trade tensions eased with a two-month extension of the existing trade truce announced as Xi Jinping arrived in Washington. The US-China Business Council described the extension as absolutely necessary.

CanSemi Technology filed for a $919 million IPO on Shenzhen’s exchange, reflecting continued capital-raising momentum in the chip sector.

The Day Ahead

No data releases or central bank operations are scheduled for 24-25 September across mainland China, Hong Kong or Taiwan. Market focus will remain on PBoC liquidity operations and any follow-through from the announced RMB bill issuance via HKMA. Investors will monitor US-China trade developments following the two-month truce extension announced during Xi Jinping’s visit to Washington.

Semiconductor-related flows may influence Taiwan equities given ongoing IPO activity by firms such as CanSemi Technology. HKMA’s aggregate balance and any cross-border payment initiatives with Bank Indonesia could also draw attention. Broader sentiment will hinge on commodity price moves, with copper serving as a key proxy for China growth expectations.

The Day Ahead (continued)

Commentary on China’s state-directed approach to AI adoption versus the US focus on frontier models may shape longer-term investor views on technology sector policy.

Other Economic Notes

The PBoC’s pledge of counter-cyclical support and offshore yuan market measures via HKMA underscore efforts to stabilize financing conditions without immediate rate or reserve-requirement changes. CanSemi Technology’s $919 million Shenzhen IPO reflects continued capital-raising momentum in China’s chip sector under self-reliance policies. Broader commentary highlighted China’s state-directed approach to AI adoption versus the US focus on frontier models.

The absence of fresh CPI, industrial production or trade prints leaves the August 0.80 percent year-on-year inflation figure as the prevailing reference point. Property sector dynamics and cross-strait investment flows remain unaddressed by new data. HKMA advanced cross-border QR payment cooperation with Bank Indonesia and prepared new CMU products for later this year.

Global Macro News

The two-month extension of the US-China trade truce was described by the US-China Business Council as absolutely necessary, easing near-term tariff risks as Xi Jinping arrived in Washington. Brent crude’s 3.83 percent jump to 107.03 and copper’s 1.43 percent gain to 6.77 signal firmer global energy and industrial metal demand that could support China’s export-oriented sectors. Gold eased 0.19 percent to 4,310.10 while Bitcoin slipped 0.16 percent to 84,248.72, indicating limited safe-haven flows into non-yuan assets.

Continuation

Global Macro News (continued)

US-China Business Council commentary stressed the importance of sustained dialogue to prevent renewed escalation. Global equity sentiment remains sensitive to any further signals from the Trump-Xi meetings on Taiwan and trade balances. These developments provide a supportive external backdrop for Greater China assets provided the truce holds.

Greater China Central Banks Watch

The PBoC reiterated its commitment to counter-cyclical support and yuan stability while announcing plans to issue RMB bills through the HKMA to deepen offshore liquidity. No MLF or LPR decisions were scheduled, and liquidity operations remained routine. HKMA maintained the USD/HKD peg at 7.84 with no aggregate balance shifts reported; the central bank also advanced cross-border QR payment cooperation with Bank Indonesia and prepared new CMU products for later this year.

CBC held no rate meetings and issued no FX intervention signals, with semiconductor export linkages remaining the primary policy transmission channel. Overall, the three central banks adopted a steady posture, with PBoC actions dominating the regional policy narrative.
