The People’s Bank of China (PBOC) is anticipated to set the USD/CNY reference rate at 7.1742, according to Reuters’ estimates. This occurs around 0115 GMT and involves the PBOC’s responsibility to determine the daily midpoint of the yuan.
The PBOC utilises a managed floating exchange rate system, allowing the yuan to fluctuate within +/- 2% of the central reference rate. The daily midpoint, set by the PBOC, guides the yuan against other currencies, mainly the US dollar.
Factors Influencing the Midpoint
This midpoint reflects market supply and demand, economic indicators, and international currency market changes. The permitted trading band allows the yuan to appreciate or depreciate up to 2% from the midpoint in one trading day.
Should the yuan approach the band limits or experience high volatility, the PBOC might intervene in the foreign exchange market. Such intervention involves buying or selling the yuan to stabilise its value and ensure a controlled adjustment of the currency.
The People’s Bank of China’s expected fix at 7.1742 signals a continued official pushback against rapid yuan depreciation. We have seen this pattern throughout mid-2025, where the central bank consistently sets the reference rate stronger than market expectations. For traders, this reinforces the idea that betting on a sharp, uncontrolled spike in USD/CNY is a risky strategy against state policy.
This management comes as China’s economy shows signs of slowing, with Q2 2025 GDP growth coming in at 4.8%, slightly below forecasts. Additionally, July’s export data showed a 1.5% year-over-year decline, indicating that softer global demand is weighing on the domestic economy. These factors create a natural downward pressure on the yuan, which the PBOC is actively trying to counterbalance.
Derivative Strategies for Traders
Given the central bank’s active role, we believe implied volatility for USD/CNY options may be too high for the coming weeks. The PBOC’s firm grip, similar to what we observed during the 2023-2024 period, effectively creates a ceiling on the currency pair. This makes derivative strategies that involve selling volatility, such as covered calls on USD/CNY, appear attractive.
Traders should expect the currency pair to operate within a well-defined range, pinned by the daily reference rate. The +/- 2% trading band is more of a theoretical boundary than a target, as intervention typically occurs long before those limits are reached. Therefore, range-bound derivative structures, like iron condors, could be used to capitalize on this managed stability.
