The People’s Bank of China (PBOC) sets the yuan’s daily midpoint, also known as renminbi, in a managed floating exchange rate system. This allows the yuan to fluctuate within a +/- 2% range around a central rate. Each day, the PBOC determines this midpoint based on market supply and demand, economic indicators, and trends in international currency markets. The trading band permits the yuan to move within a 2% range from the midpoint in one trading day. The PBOC can adjust this range based on economic conditions and policy goals. If the yuan’s value approaches these limits or shows volatility, the PBOC may intervene to stabilize its value. This helps keep the currency stable and addresses any excessive fluctuations.

Current Reference Rate Dynamics

In the managed floating system, the expected reference rate of 7.1052 suggests ongoing currency management. The PBOC establishes the daily midpoint, which anchors the yuan’s +/- 2% trading band. Traders should expect this controlled approach to continue, especially with recent economic data in mind. It’s important to understand the widening interest rate gap between China and the US that has lasted into 2025. The Federal Reserve has rates around 4.5%, while China’s rates remain low to help a slow economy. This creates downward pressure on the yuan. The strong midpoint fixing is the PBOC’s main tool to counter this pressure. This situation reminds us of market dynamics from 2023 when a similar policy gap led to prolonged yuan weakness. Historical data shows that the PBOC often set the fix stronger than expected to avoid a chaotic decline. We predict this strategy will be used heavily in the coming weeks, especially after the disappointing 4.1% GDP growth for the second quarter of 2025. For derivatives traders, this means implied volatility on USD/CNY options might stay low for a while because of the PBOC’s influence. However, this also offers a chance for long-volatility positions, like buying straddles, betting on a potential break if market pressure overpowers the central bank’s efforts. The longer the fix resists market forces, the higher the risk of a sudden adjustment.

Hedging and Speculation Strategies

We should monitor the forward market closely, as carrying long yuan positions can be costly. The forward points will likely reflect an expected depreciation of the yuan against the dollar due to the interest rate gap. This makes selling CNY forward contracts a good strategy to hedge or speculate on further weakness. The daily trading band is now a vital indicator of market stress. Recently, the spot rate has often tested the weak end of its 2% band, showing that the market is pushing for a weaker yuan than the PBOC wants. When the spot rate hits this limit, it reveals that depreciation pressures are at their peak for that trading session. Create your live VT Markets account and start trading now.
