The People’s Bank of China (PBOC) manages the daily midpoint of the Chinese yuan, also known as renminbi or RMB, through a managed floating exchange rate system. The system allows the yuan’s value to fluctuate within a prescribed range, or “band,” around a central reference rate, currently set at +/- 2%.
Each morning, the PBOC determines a midpoint for the yuan against a basket of currencies, mainly the US dollar, considering market supply and demand, economic indicators, and fluctuations in international currency markets. This midpoint acts as a reference point for daily trading activities.
Yuan’s Value Fluctuation
The yuan can move within a +/- 2% range from the midpoint in a single trading day, allowing for both appreciation and depreciation. The PBOC may adjust this range based on prevailing economic conditions and policy goals.
The PBOC intervenes in the foreign exchange market if the yuan nears the band limit or experiences high volatility, stabilising its value by buying or selling the yuan. This intervention supports a gradual and controlled adjustment of the currency’s value, ensuring overall market stability.
The People’s Bank of China appears to be guiding the yuan stronger, as shown by today’s reference rate being set consistently stronger than market estimates. This policy converges with the widely held view that the U.S. Federal Reserve is on the brink of an easing cycle. This dual dynamic presents a clear trading signal for a weaker dollar against the yuan in the coming weeks.
Given this outlook, we are looking at buying put options on the USD/CNH pair, which profit as the dollar weakens relative to the offshore yuan. Implied volatility has been relatively low, reflecting the market’s confidence in a managed decline rather than a sharp drop. This makes buying options attractive right now before any potential policy surprises could cause volatility to rise.
Global Implications and Trading Strategies
This view is supported by recent data showing U.S. core inflation has finally cooled to 2.1%, giving the Fed the green light to begin cutting rates from the highs we saw through 2024. The market is now pricing in at least two rate cuts by the end of this year, a sharp contrast to the aggressive hiking cycle of 2022-2023. We’ve already seen the USD/CNY pair fall from the 7.30 levels of late 2023 as this policy divergence became clear.
We see this as a broader theme, not just a China story, as a stronger yuan often acts as an anchor for other emerging market currencies. The MSCI Emerging Markets Currency Index is already up 3% over the past quarter, indicating a risk-on sentiment is building. Therefore, we are also considering long positions in currencies like the Korean won and the Mexican peso against the dollar as a proxy trade.
It is important to remember the PBOC’s +/- 2% daily trading band, which ensures any move will be gradual rather than a sudden collapse. The central bank is managing this appreciation, not letting the market run free. This suggests a strategy of holding positions for a multi-week trend rather than expecting a sharp, overnight repricing.
