Beijing Stopped Fighting the Yuan.
Now It's Winning.

1. Macro Backdrop: Why RMB Is Structurally Stronger

1.1 Trade Surplus as Anchor

China's external position is the primary structural driver of RMB strength. Despite elevated U.S. tariffs, China's trade surplus reached $1.189 trillion in 2025, a record and roughly 20 percent higher than 2024. Rather than collapsing under tariff pressure, exporters redirected shipments toward Europe, Australia, and Southeast Asia, and doubled down on the high-margin goods the world is clamoring for: EVs, batteries, and solar panels.^1,2,3

The mechanics work like this. Exporters earn dollars. They pay workers and suppliers in yuan. When they convert, they bid up the renminbi. Unless Beijing absorbs the dollars through official reserve accumulation — or private capital parks them offshore — a surplus that size mechanically pushes the currency higher. Capital controls limit the offshore-parking option, amplifying the conversion pressure.^2,4

A third structural driver is currency valuation itself. Using the BIS real effective exchange rate (REER) model — which adjusts for inflation differentials across trading partners — VanEck portfolio managers Eric Fine and Natalia Gurushina estimated in August 2025 that CNY was approximately 30% undervalued, while the U.S. dollar sat near record overvaluation on the same model.⁵⁸ The implication: yuan appreciation is not purely a policy choice. It is a partial correction of an embedded valuation gap that conventional flow-based analysis has systematically underestimated.

1.2 Dollar Cycle and Yield Differentials

Multiple global investment houses now forecast USD/CNY below 7.0 on a sustained basis over the next 12–18 months, with some placing it in the mid-to-high 6s. The driver: the Federal Reserve's transition from peak tightening toward a more neutral stance, which has eroded the broad dollar tailwind that pushed USD/CNY above 7.3.^15,16,17

U.S.–China yield differentials have narrowed from earlier extremes, shrinking the carry advantage of holding USD over RMB. IMF and New York Fed analyses note that as rate differentials compress, the yuan's short-run behavior increasingly resembles a more flexible currency, with less one-way pressure from the capital account side.^4,19

Inflation divergence reinforces this. IMF forecast revisions through 2025 show U.S. CPI being marked up while China's has been revised down — a widening gap that puts structural upward pressure on CNY in REER terms.⁵⁸ The feedback is self-reinforcing: a stronger yuan suppresses China's import costs and deepens its dis/deflation dynamic, while dollar weakness risks reigniting U.S. inflation. Both forces compound the case for sustained CNY strength.

1.3 PBoC Managed Float and Live Policy Signals

China's exchange-rate regime sits within a daily PBoC-set central parity with a ±2% onshore band. Recent moves confirm a controlled-appreciation bias:

1.4 Internationalisation and the Currency Credibility Motive

Beijing's push to promote RMB internationalisation (via Belt and Road financing, bilateral swap lines, and encouraged settlement) benefits from a currency seen as stable and, if anything, slightly undervalued. Controlled appreciation reinforces confidence and supports broader geopolitical and financial objectives. A depreciating currency quietly undermines all of it.^31,32,33

CSIS and IMF analyses highlight that the RMB has often traded below estimated equilibrium values, particularly when large trade surpluses and capital controls suppressed adjustment via capital flows. As reforms have gradually increased flexibility and integration, the scope for maintaining undervaluation without significant intervention has narrowed.^4,7,28,29

Tariff game theory adds a strategic layer. Trading partners negotiating with the U.S. have been tacitly signalled that post-deal currency devaluation is a deal-breaker — making appreciation, rather than devaluation, the path of least resistance for countries seeking to avoid further tariff rounds.⁵⁸ For China specifically, a straightforward devaluation to offset tariff costs would invite immediate U.S. retaliation and undermine ongoing trade negotiations. Controlled appreciation is not just financially rational: it is the dominant strategic choice in a tariff-constrained world.

1.5 External Balance Sheet: China as Net Creditor

A structural factor often missed in flow-based FX analysis is China's net international investment position (NIIP). China holds a strongly positive NIIP — roughly $5 trillion net — while the U.S. NIIP has deteriorated to approximately -$25 trillion.⁵⁸ This asymmetry is decisive: China does not have to devalue. Unlike prior depreciation cycles when China faced capital outflow pressure, today's balance sheet gives it the firepower to manage a stronger currency as a deliberate policy choice.

PBoC's gradual reduction in U.S. Treasury holdings adds a second mechanism: from a post-pandemic peak of approximately $1.1 trillion, holdings fell to approximately $693 billion by end-2025 — an 18-year low, per CNBC reporting.^58,59 As Chinese reserves rotate away from USD assets, structural downward pressure builds on the dollar and upward pressure on U.S. long yields. To the extent Chinese Government Bonds (CGBs) increasingly substitute as global reserve assets, CNY's role as a store of value is being reinforced from the demand side, not just the supply side. In 2025, the balance-sheet thesis became visible in fixing behaviour: daily PBoC fixings ran consistently stronger than bank-predicted levels, the clearest operational signal yet that Beijing was leaning into appreciation rather than capping it.

2. Volatility Regimes: Peg, Float, Reform, Shocks

2.1 Regime Map

USDRMB volatility is a sequence of structurally distinct regimes, each with its own vol range, intervention logic, and tail-risk profile. Hedging programs calibrated to one regime will be wrong-sized in the next.

2.2 Realized Volatility by Regime

Option-implied vol on CNH options prices higher in reform and stress regimes, lower in managed-appreciation phases. A hedging program that anchors to today's 4–7% range will be dangerously under-hedged if regime 3-style conditions re-emerge.^36,37

Relative to developed-market peers, CNY's realized volatility has been notably low. Bloomberg data through mid-2025 shows CNY/USD 90-day realized vol near 2–3%, versus 10–12% for JPY and 6–8% for DXY — a divergence that reflects the active policy smoothing characteristic of Regime 4 and that VanEck cites as consistent with Beijing's internationalisation objective: a stable currency is a more credible global reserve currency.⁵⁸

3. Corporate Hedging: Instruments, Regimes, and Execution

3.1 The Structural Shift in Hedging Adoption

A record 1,409 listed Chinese companies disclosed FX hedging measures in 2025, up 13.5% year-on-year. Outstanding forward contracts reached record levels. SAFE officials cite national average hedging ratios near 30%, up approximately 8 percentage points from 2020, with some coastal regions reaching 40%.^8,43

This is a structural shift from earlier cycles, where many firms either ignored FX risk or passed it through pricing. FX risk management has crossed from discretionary to regulatory expectation. The behavior that created the 1,409 number: a decade of companies sleeping through volatility that is now forcing a morning reckoning.

3.3 Regime-Aware Hedging Matrix

3.4 Execution: CNH vs. CNY, Liquidity, and Basis Risk

Onshore CNY forwards offer better pricing for firms with domestic-market access and relationships with Chinese banks; they align with CNY functional currency for hedge accounting under IAS 39/IFRS 9. Offshore CNH NDFs are the primary instrument for offshore clients without onshore access, but CNH–CNY basis and liquidity differences can introduce basis risk between the hedge and underlying exposure, particularly in stress regimes when authorities tighten CNH liquidity to discourage speculation.^4,19,34,36

For a bank FX desk, the practical implications: match exposure currency (CNY vs CNH) as closely as possible; monitor CNH–CNY basis and onshore/offshore spreads; recommend shorter tenors or blended hedges in stress episodes to manage basis risk; offer participating forwards or collars to optimize client P&L by trading off premium versus forward points versus participation.

4. Tail Risks and Outliers

The base case is controlled appreciation with 4–7% realized vol. The four tail risks below argue for maintaining optionality and embedding regime-switch logic into hedging programs rather than assuming a single benign path.

5. Trade Ideas and Next Steps

The following action framework reflects current regime conditions: moderate realized vol (4–7%), controlled appreciation bias, SAFE regulatory pressure toward 30–40% hedge ratios, and forward points at historically favorable levels for exporters.
