The People’s Bank of China (PBOC), the central bank of China, regulates the daily midpoint of the yuan, also called the renminbi (RMB). The PBOC operates a managed floating exchange rate system, allowing the yuan’s value to vary within a specified band around a central reference rate, currently set at +/- 2%.
For today, the PBOC has set the USD/CNY reference rate at 7.1128. This is slightly stronger than the estimated rate of 7.1174 and matches the previous close of 7.1128.
Liquidity Operations
Additionally, the PBOC conducted a liquidity operation by injecting 354 billion yuan through 7-day reverse repos at a rate of 1.40%. This resulted in a net liquidity injection of 124.3 billion yuan into the financial system.
The central bank’s actions signal a clear policy of managed depreciation. By setting a yuan fix stronger than market expectations, the PBOC is preventing a rapid, disorderly sell-off. The simultaneous cash injection shows they are still focused on providing enough liquidity to support the domestic economy.
We see this as a response to both domestic weakness and external pressure. Recent data from August 2025 showed industrial production slowing, and with the US Federal Reserve holding rates around 4.75%, the dollar remains strong, putting downward pressure on the yuan. This balancing act is designed to stimulate the economy without triggering capital flight.
This strategy is not new; we saw a similar playbook unfold through much of 2023 and 2024. During that period, the PBOC consistently used strong daily fixings to anchor the currency while domestic interest rates remained low to support growth. The goal then, as it appears to be now, is to maintain stability above all else.
Opportunities for Traders
For derivative traders, this suggests that implied volatility in USD/CNY options may be overpriced in the near term. The central bank is actively suppressing large, sudden moves, making strategies that profit from range-bound trading, like selling strangles, potentially attractive. We are essentially betting on the PBOC’s ability to keep the currency’s decline slow and steady.
Given the interest rate differential between the US and China, the path of least resistance for the yuan is still weaker over the medium term. This points towards opportunities in the forward markets, where one might position for a gradual grind higher in USD/CNY over the next three to six months. The key is to structure trades that benefit from a slow depreciation rather than a sharp break.
The main risk to this view is a sudden deterioration in China’s economic data, such as the upcoming Q3 GDP figures. If growth slows more than anticipated, authorities could be forced to abandon their stable stance and allow for a faster depreciation to boost exports. Therefore, we will be watching high-frequency data very closely for any signs of an accelerated slowdown.
