The People’s Bank of China (PBOC) is responsible for setting the daily midpoint for the yuan, also known as renminbi. This process forms part of a managed floating exchange rate system where the yuan’s value can fluctuate within a defined range, currently set at +/- 2% around a central reference rate.
Setting the Midpoint
Each morning, the PBOC establishes a midpoint for the yuan against a basket of currencies, taking into account market supply and demand, economic indicators, and international currency fluctuations. This midpoint acts as a reference for the trading day. The PBOC allows the yuan to move within a band of +/- 2% around the midpoint, potentially adjusting this range based on economic conditions.
If the yuan’s value nears the limit of the trading band or exhibits excessive volatility, the PBOC may step in by trading the yuan to stabilise its value. This intervention aims to maintain a controlled and gradual adjustment in the currency’s value. The system seeks to balance stable currency conditions with necessary economic adjustments.
With the USD/CNY midpoint set near 7.15, we are seeing a clear signal from the People’s Bank of China. The central bank is managing a gradual depreciation of the yuan against a strong US dollar. This action aims to support the Chinese economy without causing alarm or triggering rapid capital outflows.
This strategy makes sense when we look at recent data. China’s export figures for August 2025 showed a modest 1.5% year-over-year decline, indicating that international demand remains sluggish. A carefully managed, weaker currency makes Chinese goods more competitive abroad and supports the manufacturing sector.
Trading Strategy Insight
For traders, the key takeaway is the +/- 2% trading band is more of a theoretical boundary than a daily reality. The PBOC’s constant presence in the market means actual daily moves are much smaller. We should not expect sudden, volatile swings but rather a slow, controlled grind in the currency’s value.
This environment of low realized volatility points towards specific derivative strategies. One-month implied volatility for USD/CNY options has compressed to around 3.5%, making it attractive to sell premium. We should consider strategies like short strangles or iron condors that profit from the currency staying within a predictable range.
Looking back, we saw the yuan weaken past 7.30 in late 2023, so the current level is not unprecedented. However, concerns about capital flight are higher now, especially after foreign direct investment figures for Q2 2025 showed a net outflow of $12 billion. This is why the PBOC is intervening so carefully to project stability.
Therefore, our approach in the coming weeks should focus on range-bound trades rather than betting on a breakout. We can use futures options to define a likely trading channel, such as 7.12 to 7.22. Selling options outside of this expected range allows us to collect income from the market’s stability.
