The People’s Bank of China (PBOC) has set the USD/CNY reference rate at 7.1161, which contrasts with the estimated rate of 7.1551. This managed floating exchange rate system permits the yuan to fluctuate within a predetermined range of +/- 2% around this midpoint.
The strength of this rate, the highest since 6 November last year, deviates from the previous close of 7.1666. Additionally, the PBOC has injected 288.4 billion yuan through 7-day reverse repos at a rate of 1.40%. With 266.5 billion yuan maturing today, this results in a net injection of 21.9 billion yuan.
Yuan Fixing Announcement
Today’s yuan fixing is a powerful signal from policymakers that they intend to halt the currency’s slide. The rate was set significantly stronger than market expectations, showing a clear intent to support the yuan. This suggests that continuing to bet on a weaker yuan, or being long USD/CNY, has become a much riskier position.
We are seeing this after China posted a surprisingly robust $89 billion trade surplus for July 2025, a figure that should theoretically support the currency. However, the yuan had continued to weaken amid concerns over the property sector and slowing domestic demand. The People’s Bank of China is now forcefully stepping in to counter that negative sentiment and align the currency with stronger trade data.
This action is reminiscent of the period in late 2023 when the central bank consistently defended the 7.30 level against the dollar, effectively creating a ceiling for months. We may be seeing the formation of a new, lower ceiling around the 7.15-7.20 area now. This managed stability suggests that volatility in the currency pair may decrease, making certain option strategies more attractive.
Impacts on Derivatives and Goods
For derivative traders, this means that selling short-dated USD/CNY call options could be a viable strategy, as the central bank is actively capping the potential for the dollar to rise further. The implied volatility for the yuan, which rose to a six-month high of 4.8% last week, may now be overpriced given the bank’s direct intervention. A less aggressive approach would be to use call spreads to bet on a limited upside for the dollar.
This move to strengthen the yuan will likely have knock-on effects for Chinese equities and global commodities. A stronger currency makes Chinese goods more expensive abroad, which could act as a headwind for the nation’s export-heavy stocks. Conversely, it increases China’s purchasing power for raw materials, potentially providing support for commodities like copper and iron ore, which have seen prices soften in recent months.
