PBOC FX reserve ratio rises to 6% to slow yuan rally
The PBOC FX reserve ratio will increase to 6% from 4% on November 15, a roughly $24 billion liquidity drain that sent the onshore yuan down as much as 0.37% to 6.6728.

Beijing is trying to slow a currency rally without a blunt mid-market intervention. The PBOC FX reserve ratio will rise by two percentage points to 6% from 4% on November 15, a liquidity drain Reuters calculates at about $24 billion that knocked the onshore yuan lower on Tuesday.
What happened
The Straits Times, citing Reuters, said the People's Bank of China announced the foreign-exchange reserve requirement increase on November 3, effective November 15, aiming to strengthen management of FX liquidity at financial institutions. The onshore yuan weakened as much as 0.37% to 6.6728 per dollar, its weakest since October 23 and on course for the biggest one-day drop since mid-May. The daily midpoint was set at 6.7150.
TradingView's Trading Economics brief said the offshore yuan slid around 0.3% to about 6.66 per dollar, retreating from a more than four-year high after the same PBOC FX reserve ratio hike. The move makes it costlier for banks to hold dollars and is meant to discourage selling them into a one-way yuan bid.
Both accounts place the yuan's 2026 gain above 5% against the dollar, helped by strong exports -- TradingView cited September shipments up 36.3% year on year to $447.18 billion -- and heavy corporate FX conversion. Analysts quoted by Reuters via Straits Times called the step largely symbolic relative to that surplus-driven supply of dollars.
Why it matters
For global markets the signal matters more than the $24 billion arithmetic. A PBOC FX reserve ratio rise is a clean way to show discomfort with the pace of appreciation while still insisting the market sets the rate, language deputy governor Zou Lan repeated in Hong Kong on November 3 according to the Straits Times report.
Asia FX desks will map spill-overs into the yen and won. Our Katayama yen warning coverage already flagged Japanese sensitivity to disorderly moves; a softer yuan fix can ease some regional appreciation pressure even if it does not reverse China's trend.
Trade-cycle data still dominate the medium-term yuan view. Korea's export boom and China's manufacturing pulse, tracked in our Korea record exports story and related China PMI prints, help explain why corporates keep selling dollars even after a reserve tweak.
Crypto and risk assets felt a first echo when CoinDesk noted the yuan snapping a 13-day winning streak after banks were told to hold more FX reserves, a reminder that China FX plumbing can show up in Tuesday Asia risk tapes.
Exporters converting dollars after the September surge still dominate the flow picture, so a single two-point reserve tweak may only buy the central bank time rather than a durable top in the yuan.
Dollar liquidity drained into required reserves also tightens onshore FX swap pricing at the margin, even when strategists still call the headline move mostly symbolic.
What's next
The November 15 effective date leaves nearly two weeks for banks to position before the higher ratio binds. The Straits Times Reuters dispatch carries the official percentages and the $24 billion estimate.
If the reserve-ratio step fails to cool the bid, markets will look for weaker midpoints or verbal guidance rather than an immediate second reserve hike.
