The People’s Bank of China (PBOC) manages the daily midpoint of the yuan, aligning it with various global currencies, primarily the US dollar. This system allows the yuan to fluctuate within a range, currently set at +/- 2%, around a central reference rate.
Each morning, the PBOC sets this midpoint based on factors like market supply and demand, economic data, and international currency movements. This midpoint guides that day’s trading. The yuan may move within a +/- 2% range around this midpoint, with changes made according to economic conditions.
PBOC Intervention
When the yuan’s value nears the band limit or shows excessive volatility, the PBOC may intervene by buying or selling yuans to stabilise their value, ensuring controlled adjustments. Recent US Federal Reserve rate cuts have reduced the rate gap between the dollar and the yuan, affecting USD/CNY dynamics.
This situation introduces a bearish aspect for USD/CNY, with increased short positions on the dollar suggesting challenges in the trading environment.
The recent rate cut from the Federal Reserve is putting clear downward pressure on the USD/CNY pair. We are seeing this reflected in the People’s Bank of China’s expected reference rate of 7.1113, which signals a desire for a stronger yuan. This action narrows the interest rate gap that has favored the dollar, making yuan assets more appealing.
Looking at the broader context, the Fed has now reduced the federal funds rate to 4.50% in a series of cuts throughout 2025, a stark reversal from the hawkish stance of previous years. Meanwhile, China’s Q2 2025 GDP came in at a stable 4.9%, suggesting government stimulus measures are finding some traction. This economic backdrop gives the PBOC room to guide the yuan stronger without jeopardizing its recovery.
Market Dynamics
The main challenge now is that betting against the dollar has become a crowded trade. Net short positions on the U.S. dollar index have recently expanded to levels we haven’t seen since early 2024, creating a risk of a sharp upward correction on any unexpectedly strong U.S. data. For this reason, traders may prefer using options to define risk, such as buying puts on USD/CNY, rather than holding outright short positions.
We must also respect the PBOC’s control over the currency within its +/- 2% trading band. This managed float system has consistently suppressed volatility, which often makes option premiums seem inexpensive relative to the underlying economic tensions. If market forces continue to push for a stronger yuan against the central bank’s gradual pace, implied volatility could rise, presenting a distinct trading opportunity.
This situation is reminiscent of the prolonged battle around the 7.30 level we witnessed back in late 2023 and 2024. During that time, the PBOC frequently used stronger-than-expected daily fixes to lean against market sentiment and prevent excessive weakness. Traders should anticipate similar interventions to manage the pace of any appreciation in the coming weeks, which could cap gains on directional bets.
