The People’s Bank of China (PBOC) manages the daily midpoint of the yuan, also referred to as the renminbi or RMB. The central bank employs a managed floating exchange rate system, permitting the yuan’s value to move within a specified band around a central reference rate, known as the midpoint.
This band is currently set at plus or minus 2%. The yuan’s previous closing rate was 7.1829. The PBOC has injected 118.5 billion yuan through 7-day reverse repos at an interest rate of 1.40%.
Tightening Liquidity
Today, 138.5 billion yuan is set to mature. This results in a net drain of 20 billion yuan from the financial system.
We are seeing the People’s Bank of China send a subtle but important signal today, August 13, 2025. By draining a net 20 billion yuan from the system, they are indicating a preference for tighter liquidity. This move suggests a desire to support the yuan and prevent it from weakening further.
This action is particularly noteworthy given the yuan’s recent flirtation with the 7.20 level against the dollar last week. The previous close at 7.1829 shows the pressure is still on, and this small liquidity drain is a defense. We have seen this strategy before, particularly during the defense of the 7.30 level back in late 2023.
The challenge for the PBOC comes from abroad, as the latest US jobs report for July 2025 was surprisingly strong, bolstering the dollar. This puts upward pressure on the USD/CNY pair, creating a direct conflict with the PBOC’s stabilization efforts. This tension between a hawkish Fed and a stability-focused PBOC is the key dynamic for the coming weeks.
Strategic Stability Messaging
For derivative traders, this points towards a period of managed stability rather than a major breakout. Selling options volatility in USD/CNH could be a prudent strategy, as the PBOC is likely to use its daily midpoint fixing to curb sharp movements. Implied volatility for one-month options has already ticked down to 4.1% from a recent high of 4.5%, reflecting this expectation.
Recent domestic data supports this view, with China’s July 2025 exports seeing only modest 1.5% year-over-year growth. This weak external demand means a significantly stronger yuan is unlikely, reinforcing the case for a range-bound currency. The PBOC is balancing the need for stability without hurting the export sector.
Therefore, traders should watch the daily yuan midpoint fixing with extreme focus. Any significant deviation from market expectations will be the best clue to the PBOC’s next move. Betting on the yuan remaining within a tight 7.15 to 7.22 range seems like the most logical position for now.
