The People’s Bank of China (PBOC), as China’s central bank, determines the daily midpoint for the yuan’s exchange rate. It employs a managed floating exchange rate system, allowing the yuan’s value to move within a band around a central reference rate.
Current Exchange Rate Band
The current band permits a fluctuation of +/- 2%. For today, the PBOC set the USD/CNY reference rate at 7.1, slightly below the estimated rate of 7.1159. The previous closing rate was 7.1188.
Additionally, the PBOC injected 240.5 billion yuan through 7-day reverse repos at an interest rate of 1.40%. This action resulted in a net drain of 39.5 billion yuan.
We see the central bank signaling a clear intention to slow the yuan’s depreciation against the dollar. Setting the daily reference rate significantly stronger than market estimates is a direct move to shore up confidence. This action suggests a floor is being established around the 7.1 level for now.
This intervention comes as China’s recent economic data has shown some weakness, with Q2 2025 GDP growth coming in at 4.8%, just below the official target. Coupled with a US Federal Reserve that has maintained higher interest rates, the yield differential between US and Chinese bonds has remained wide, putting natural weakening pressure on the currency. The net liquidity drain, though small, reinforces the bank’s preference for stability over aggressive easing.
Recent Historical Context
We have seen this playbook before, particularly during the 2022-2023 period when similar economic pressures mounted. Back then, the PBOC also used consistently strong fixings and other policy tools to manage the currency’s decline and prevent speculative attacks. History shows these interventions can successfully smooth out volatility for extended periods.
For derivative traders, this means that implied volatility on the yuan is likely to be suppressed in the near term. Strategies that profit from range-bound price action, like selling out-of-the-money call options on USD/CNY, could be favorable. The central bank’s visible hand makes a sudden, sharp spike above levels like 7.2 less probable in the coming weeks.
Therefore, while the broader trend may still point to a weaker yuan, outright long USD/CNY positions carry the risk of fighting the central bank. A more cautious approach would be to use option spreads that define risk. This allows traders to maintain a moderately bearish view on the yuan while being protected from the PBOC’s efforts to curb price swings.
