The People’s Bank of China (PBOC), as China’s central bank, determines the daily midpoint of the yuan, also known as the renminbi or RMB. The bank operates under a managed floating exchange rate system, allowing the yuan’s value to fluctuate within a predefined range, or “band,” of +/- 2% around the central reference rate.

Recently, the PBOC set the midpoint at its strongest level for the yuan since 8 November 2024, indicating the lowest point for USD/CNY. The previous close was recorded at 7.1772.

PBOC’s Strongest Midpoint

Furthermore, the PBOC injected 406.5 billion yuan through 7-day reverse repos at an interest rate of 1.40%. With 197.3 billion yuan maturing on the same day, the net injection amounted to 209.2 billion yuan.

This move by the central bank reflects a deliberate effort to guide the currency higher without creating abrupt disruptions in short-term liquidity. The stronger midpoint acts as a clear signal of policy intent—it pushes back against depreciation pressures and aligns with broader objectives to stabilise capital outflows and shore up sentiment.

The net injection of over 200 billion yuan via short-term reverse repos suggests that policymakers are attempting to balance currency guidance alongside the need to manage liquidity delicately. While the injection is temporary by design, the scale—and the slightly reduced rate of 1.40%—implies a leaning toward keeping conditions loose enough to support domestic credit operations without loosening to the point of fuelling speculative activity.

For those assessing short-term rate sensitivity and volatility expectations, the directional intent is tangible. A firmer fix, coupled with controlled liquidity additions, invites a response in short-dated vol pricing and near-term interest rate bets. Yuan forwards are likely to see modest selling pressure, particularly in tenor buckets inside one month, as traders anticipate reinforced control around spot movements.

Zhou’s strategy demonstrates that they’re comfortable using daily midpoint settings not just as a reactive tool, but as a proactive stance to guide broader market expectations. This sets an anchor for the range traders can reasonably price in over the coming weeks. As a result, we should expect compressed range potential in offshore yuan trading—especially during the overlapping Asian-Europe sessions—absent a sharp external shock.

Implications For Short Term Trades

Meanwhile, the volume and timing of the reverse repo operation suggest that policymakers are breeding stability without extending broader system leverage. They injected after some short-term maturities rolled off, essentially providing just enough cushion to avoid tension within interbank funding but stopping short of net new easing. That approach tightens the scope for overnight repo rate spikes but doesn’t signal a shift toward a looser stance either.

It leaves us in a position of cautious range-setting. That means tighter options straddles in the 7-day to 1-month area may be worth reviewing, particularly if implieds continue to outstrip realised figures. Costings for downside USD/CNY hedges may build if the trend of firm midpoints is maintained, especially if spot begins to gravitate more tightly to daily fixings.

Other traders might also take notice of Wu’s monetary tools being somewhat predictable, relying more on pace than volume. This method gives scope for rebalancing exposure on aggressive forward bets that assume a volatile currency move. There’s reduced space for surprise, particularly for arbitrage between the onshore and offshore market, due to the increased sensitivity in fix-driven reactions.

From our vantage point, these operations give a relatively clear framework with which traders might measure deviation risks and respond ahead of local macro data or wider dollar positioning shifts. Timing will now be essential if one is to catch inefficiencies arising from mispriced forwards or misaligned short-term rate assumptions. Each fix now becomes more than a daily formality—it has to be priced with anticipation, not reaction.

As usual, the spread between short-tenor CNH and CNY derivatives needs close watching. There’s a heightened likelihood that periods of mild dislocation invite fresh central bank activity, either through forward guidance or direct liquidity nudges. That tendency often places a ceiling on moves outside expected parameters and necessitates more nimble rotation of position sizes.

In terms of action, clear levels have now been marked—those that carry both symbolic and technical meaning. If midpoints continue to act as anchoring points, then anchoring our own short-term trades to those markers becomes even more viable. Development will be less about chasing an absolute trend and more about anticipating zones of stagnation or orderly correction, especially where liquidity cushions are simultaneously released or retracted.
