The People’s Bank of China (PBOC) sets the daily midpoint for the yuan, or renminbi (RMB), against a basket of currencies, prominently including the US dollar. This reference rate is due around 0115 GMT each day. The PBOC uses a managed floating exchange rate system, allowing the yuan to fluctuate within a specified range or “band” of +/- 2% from this midpoint.
This process involves the PBOC considering factors like market supply and demand, economic indicators, and international currency market movements. The central bank may adjust the trading band based on economic conditions and policy goals. If the yuan nears the band’s limits or becomes excessively volatile, the PBOC might intervene by buying or selling yuan.
Controlled Alteration Of The Yuan’s Value
The trading band facilitates a controlled alteration of the yuan’s value, ensuring that it can only shift by a maximum of 2% from the midpoint in a single day. This helps maintain stability in the foreign exchange market, while allowing for necessary adjustments based on prevailing economic circumstances.
The expected USD/CNY reference rate near 7.2062 suggests the People’s Bank of China is continuing its policy of managed depreciation. This signals to us that the authorities will tolerate a weaker yuan, but will not allow a disorderly slide. Traders should anticipate continued intervention to smooth out any sharp moves.
Looking back, we saw this pattern throughout 2023 and 2024 amid a persistent property sector crisis and weak consumer demand. During that period, the PBOC consistently set the daily fix stronger than market expectations to prevent rapid capital flight. This history shows us the bank’s priority is stability, so we should not expect the +/- 2% trading band to be aggressively tested.
Focus On Stability
This focus on stability has kept actual currency volatility low, even as economic pressures have mounted. Implied volatility on USD/CNY options has therefore been steadily decreasing over the past year. This environment favors strategies that profit from low volatility, such as selling out-of-the-money puts and calls.
A weaker currency has also been a crucial tool for supporting China’s manufacturing sector. We can see its effect in past data; for example, China’s exports rose by 7.6% year-over-year in May 2024, beating expectations at the time. This successful use of a managed float means policymakers are likely to continue this strategy in the coming weeks.
Given this, derivative traders should position for a slow, controlled grind higher in the USD/CNY pair rather than a sudden breakout. Strategies like buying call spreads on USD/CNY could be effective, as they profit from a limited upward move while capping potential losses. Aggressive bets on a sharp depreciation are unlikely to pay off due to the high probability of central bank intervention.
