Reuters poll: PBOC likely to fix yuan midpoint at 6.6625

• Chinese central bank and regulators set to discuss stock market support following unprecedented 12-week decline

Around 0115 GMT (2115 US Eastern time), the People's Bank of China is due to announce the daily USD/CNY reference rate, a figure that remains one of the most closely watched signals in Asian foreign exchange markets.

Under its managed floating exchange rate regime, China permits the renminbi (yuan) to trade within a specified range around a daily central reference rate, or midpoint, determined by the PBOC. The current onshore trading band allows the currency to move plus or minus 2% from the official midpoint.

Each morning, the PBOC sets the midpoint based on various inputs, including the previous day's closing price, moves in major currencies (especially the US dollar), broader international FX conditions, and domestic considerations such as capital flows, growth momentum, and financial stability goals. The calculation is not purely mechanical, giving policymakers discretion to guide market expectations.

After the midpoint is announced, onshore USD/CNY can trade freely within the allowed band. If market pressures push the yuan toward either edge of that range, the central bank may step in to smooth volatility. Intervention can involve direct buying or selling of yuan, adjustments to liquidity conditions, or guidance through state-owned banks.

Consequently, the daily fixing is often interpreted as a policy signal rather than just a technical reference point. A stronger-than-expected CNY midpoint is typically read as a sign the PBOC is leaning against depreciation pressure, while a weaker fixing can indicate tolerance for a softer currency, often in response to dollar strength or domestic economic headwinds.

During periods of heightened global volatility—such as shifts in US rate expectations, trade tensions, or capital flow pressures—the fixing takes on added significance. For investors, it provides insight into Beijing's currency priorities, balancing competitiveness, capital stability, and financial market confidence.
