Determining The Midpoint
Each morning, the PBOC determines a midpoint for the yuan against a group of currencies, mainly focusing on the US dollar. The midpoint considers factors like market supply and demand, economic data, and the status of the global currency market. This midpoint serves as the reference point for the day’s trading activities. The PBOC allows the yuan to move within a +/- 2% range around the midpoint, meaning it can increase or decrease up to 2% from the midpoint in a single trading day. The central bank may change this range based on economic conditions and policy goals. If the yuan approaches the limits of the trading band or shows too much volatility, the PBOC intervenes in the foreign exchange market. This intervention includes buying or selling the yuan to ensure stability and a gradual adjustment in currency value. The expected USD/CNY fixing near 7.18 suggests the People’s Bank of China is continuing its policy of managed depreciation. This is seen as an official signal to prevent a significant drop in the yuan’s value. This approach aligns with recent actions, where the central bank has set the daily rate higher than market forecasts to reduce weakening pressure. China’s latest economic figures from the second quarter of 2025 showed GDP growth at 4.8%, just missing the official 5% target, which may tempt policymakers to allow a weaker currency to boost exports. However, concerns over capital outflows could accelerate if the yuan falls rapidly. The US Federal Reserve’s decision last month to maintain a strict approach also keeps the dollar strong, adding to the pressure.Derivative Trading Strategies
For derivative traders, this controlled environment suggests that strategies based on a slow, steady decline of the yuan are more sensible than expecting a sharp drop. Selling volatility could be an attractive option since the PBOC’s management and the +/- 2% trading band make large, unexpected daily swings unlikely. We should focus on options strategies that benefit from low volatility, such as iron condors. Create your live VT Markets account and start trading now.
