Yuan Central Parity Rate Falls for Third Straight Day as US-Iran 'Dual-Track Game' Intensifies

On August 25, the yuan central parity rate against the dollar was set at 6.7852, down 11 basis points from the previous trading day, marking a third consecutive daily decline. Previously, on August 20, the rate stood at 6.7808, up 46 points, followed by a 9-point cut on August 21 and a 24-point cut on August 24, bringing the cumulative decline over the three days to 44 basis points by August 25, as the rate shifted into a pullback after three straight days of sharp gains.

**Central Parity Pulls Back but Offshore Rate Remains Firm**

The consecutive decline in the central parity rate largely reflects a technical correction after the rapid earlier appreciation. Market sources indicate that the offshore yuan has remained in a firm range recently, with a weaker dollar and falling energy prices providing support for the currency. Market participants noted that lower oil prices have eased imported inflationary pressures for China as an energy-importing economy, while a softer dollar index has also opened room for Asian currencies to appreciate. The dollar/offshore yuan pair is currently trading around 6.72709, notably stronger than the central parity rate, suggesting that spot market pricing for the yuan remains relatively positive.

**US-Iran 'Dual-Track Game' Amplifies Volatility**

US-Iran negotiations are characterized by a "fight-and-talk" dynamic, with geopolitical risks not fully subsiding. According to analysis from Capital Futures, while the Trump administration currently shows no intention of reigniting full-scale conflict, the interim deal leaning toward Iran has drawn criticism from multiple quarters; if a comprehensive peace agreement cannot be finalized by autumn, the bargaining landscape between the two sides could shift, with a high probability of talks breaking down. Analyst Clement believes that the repeated tug-of-war in bargaining power between the two sides will not lead to a full-scale prolonged war, but it does mean the world will remain under sustained risk of geopolitical conflict over the long term.

**Key Variables for Exchange Rate Direction**

The yuan's subsequent trajectory still depends on the triple effect of the dollar index, oil prices, and central parity signals. If the US-Iran situation eases temporarily and oil prices continue to fall, the yuan may maintain a firm but volatile range; conversely, a resurgence of geopolitical risks or a dollar rebound could further accumulate downward pressure on the central parity rate. Market participants caution that consecutive gains or losses in the central parity rate do not in themselves constitute a trend reversal signal, and judgments should be made in conjunction with spot trading volumes and official pricing direction.
