Beijing just pulled the handbrake on one of the strongest currency rallies in Asia this year. On August 25, the People’s Bank of China set its daily yuan midpoint at 6.7852 per dollar, landing 633 pips below the Reuters consensus estimate. That gap is the widest weak-side deviation since February 27, when the PBOC went even further with an 800-pip surprise.
The timing matters. The yuan has been on a tear in 2026, posting year-to-date gains of roughly 4% and recently touching 3.5-year highs against the dollar.
How yuan fixing actually works
China doesn’t let its currency float freely like the dollar or euro. Instead, the PBOC sets a daily reference rate, called the midpoint, each morning before onshore trading begins. The onshore spot yuan can then trade within a band of plus or minus 2% around that fixed point.
Reuters polls a panel of market participants each day to produce a consensus estimate for the fix. The gap between that estimate and the actual fix is how analysts gauge the PBOC’s intent.
A pattern emerges since July
This isn’t an isolated move. Since late July 2026, the PBOC has established a visible pattern of fixing the midpoint well below market expectations. Prior deviations of 581 and 593 pips were recorded in recent weeks, suggesting a coordinated campaign rather than a one-off adjustment.
For context, the last time the PBOC deployed a deviation this large was February 27, when it set the midpoint 800 pips weaker than the estimate.
Why Beijing wants a slower climb, not a reversal
A stronger yuan makes Chinese exports more expensive abroad. But a dramatically weaker yuan would invite accusations of currency manipulation and could destabilize capital flows. Beijing is essentially threading a needle, having accepted a 4% year-to-date gain while using the daily fix to prevent the market from getting ahead of itself.
A US dollar that has generally weakened in 2026 has been one of the primary forces pushing the yuan higher, meaning the PBOC is partly fighting against external currents rather than domestic ones.
What forex traders and investors should watch
Forex traders who have been riding the yuan’s strength should pay close attention to the daily fix announcements. The pattern since July has been consistent enough that each morning’s number effectively functions as a policy statement.
For investors in Chinese equities and bonds, a 4% gain in the yuan this year has been a tailwind for foreign holders of Chinese assets. If the PBOC succeeds in slowing that appreciation, the currency contribution to total returns will diminish, even if underlying asset prices continue to rise.
After the 800-pip deviation on February 27, the yuan’s appreciation paused for several weeks before resuming.
