The People’s Bank of China (PBOC) manages the yuan using a controlled floating exchange rate system. This method permits the currency to fluctuate within a limited range around a set central reference rate, currently maintained at +/- 2%.
The central bank recently set the USD/CNY central rate at 7.1027, slightly under the market estimate of 7.1159, while the prior close was 7.1175. Additionally, the PBOC introduced 287 billion yuan through 7-day reverse repos at an interest rate of 1.40%, leading to a net injection of 40 billion yuan into the financial system.
Central Bank Signals Support
The central bank’s stronger-than-expected yuan fixing is a clear signal of its intent to support the currency and prevent excessive weakness. We see this as a move to manage capital flows and project stability in the face of market pressure. This means we should be cautious about positioning for a sharp depreciation of the yuan in the near term.
For our FX options strategy, this strong guidance suggests selling USD/CNY call options with a strike price well above the current level could be profitable. The PBOC is effectively capping the upside for the dollar against the yuan, which should suppress volatility and allow us to collect premium. This is a tactic that worked well when we observed similar interventions back in 2023 to defend the 7.30 level.
This action comes as recent data for August 2025 showed a persistent, albeit manageable, net capital outflow of $15 billion from China’s financial markets. Furthermore, industrial production figures for Q3 2025, released last week, came in at 3.9%, slightly below expectations. The PBOC’s move today is likely a direct response to this data, aiming to bolster investor confidence before it wanes further.
Interest Rate Strategy
At the same time, the net liquidity injection shows that the authorities are not willing to tighten domestic financial conditions. This move is intended to keep short-term borrowing costs low to support the economy. This dual approach indicates a policy of external strength and internal accommodation.
This creates an opportunity in the interest rate swap market, as the policy should keep short-term rates anchored. We believe a yield curve steepener trade, where we receive fixed on short-dated swaps and pay fixed on longer-dated ones, is logical. The front end of the curve will likely remain suppressed by these liquidity injections, while the back end has more room to rise.
Overall, the conflicting policy goals suggest the USD/CNY pair will likely remain in a managed range in the coming weeks. We should prioritize strategies that benefit from this stability, such as option selling and relative value trades on the interest rate curve. Directional bets on a major currency breakout appear risky until the PBOC signals a change in its stance.
