The People’s Bank of China (PBOC) is responsible for setting the daily midpoint for the yuan, or renminbi (RMB). It uses a managed floating exchange rate system, allowing the yuan to move within a controlled range based on a central reference rate. Every morning, the PBOC determines this midpoint against a basket of currencies, mainly the US dollar. Factors influencing this include market supply and demand, economic indicators, and global market changes. The midpoint serves as a guide for daily trading.

Yuan Trading Range

The yuan can fluctuate within a +/- 2% range around the midpoint. This means it can rise or fall by a maximum of 2% in a single trading day. The PBOC may adjust this trading band based on economic conditions and policy goals. If the yuan gets close to the edge of its band or if there’s too much volatility, the PBOC might intervene. This could involve buying or selling yuan to stabilize its value, helping to keep the currency’s market position steady. This article explains how the PBOC manages the yuan’s exchange rate. Essentially, the central bank sets a daily guide price, known as the midpoint. This midpoint directs daily trading and keeps prices within a limited margin. The 2% band protects against sudden market shocks and avoids drastic price changes that could unsettle markets or create imbalance.

Setting the Midpoint and Market Implications

Importantly, the midpoint isn’t set randomly. The central bank looks at the previous day’s currency movements, economic signals, and international capital flow changes. Although the system seems automatic, human decisions play a key role. Interventions aren’t common, but the PBOC may act when prices become too volatile. What does this mean for price action? We can expect the yuan’s volatility to stay relatively stable unless economic pressures change the midpoint significantly. When this shift occurs, it can impact nearby currency pairs, especially those sensitive to Asian currencies. As the midpoint changes gradually or suddenly, certain trading setups tied to implied volatility or delta-hedging might become more reactive. Recently, midpoints have been adjusted slightly downward over several sessions. This trend affects spot markets and increases forward pressure, which can be challenging for positions that anticipate changes too far in advance. Offshore one-month implied volatility has tightened, showing the PBOC’s effective communication even with limited transparency. Essentially, we’re working within known limits, and these price bands keep market movements predictable. Lately, investors are paying close attention to any signs of potential easing or tightening. Some experts suggest a greater tolerance for depreciation, while others emphasize the importance of stability. When Liu mentioned the PBOC’s commitment to keeping order in FX markets, it highlighted the connection between forward volatility curves and this positioning. In this situation, it’s wise to reassess gamma exposure, particularly in USD/CNH structures at the extremes of daily movement. Short-term options may start favoring higher protection costs if news begins to lean toward cautious easing, and risk reversal adjustments have already begun. As we enter the second half of the month, it’s essential to look for any patterns in consecutive midpoint fixings. Repetition beyond three sessions often signals positioning alerts. Cross-asset correlations support this: when dollar-onshore trading diverges from offshore futures pricing for a second consecutive day, spreads can tighten, with a quick reversion if liquidity decreases rapidly. It’s crucial to monitor hard data closely. Pay attention not only to published indicators but also to settlement flows, as discrepancies can signal changes before they’re reflected in the official fixing. Additionally, if swap points start steepening while we’re still trading near the edges, it might be a cue to reduce carry exposures, especially for durations affected by monetary actions. Now is not the time to chase yields indiscriminately. The controlled fluctuation band limits opportunities for drastic moves in implieds. Although some spreads may seem appealing, they are attractive because the likelihood of further intervention backs them up – a reminder not to make hasty guesses. Ultimately, directional strategies will continue to be guided by signals from the PBOC. How we interpret these signals and the value we assign to them will influence our positioning in the weeks to come. Create your live VT Markets account and start trading now.
