PBOC Institutionalizes Treasury Operations Amid Offshore RMB Breaks 6.8

Dual-Track Synchronization in Macro Liquidity: The Deeper Signals Behind the Institutionalization of Treasury Trading and Offshore RMB’s Breakout Rally

In April, China’s macro liquidity exhibited a rare “dual-track, same-direction” dynamic: First, the People’s Bank of China (PBOC) disclosed for the first time that its open-market treasury trading operations resulted in a net liquidity injection of RMB 40 billion. Second, the offshore RMB (CNH) exchange rate surged past the 6.8 threshold—a 22-month high. At first glance, these appear to be two independent developments. In reality, however, they mark a pivotal turning point where fiscal–monetary coordination has moved from theory into practice and investor confidence in capital-account openness is undergoing tangible recovery. This dual impetus not only signifies a structural upgrade in the policy toolkit but may also trigger a chain reaction—including renewed inflows of northbound funds, re-rating of Hong Kong-listed tech stocks, and sustained outperformance of growth-oriented A-share equities. The Hang Seng Tech Index’s same-day surge of 3.06% was no coincidence.

Treasury Trading Officially “Institutionalized”: From Fiscal–Monetary Coordination Theory to Operational Reality

For years, “coordination between fiscal and monetary policy” remained largely rhetorical—confined to policy statements. By contrast, the PBOC’s April announcement stating it had achieved a “net liquidity injection of RMB 40 billion via open-market treasury trading” carries landmark significance: This marks the first time treasury trading has been officially defined as a regularized, quantifiable structural monetary policy instrument—not merely an ad hoc liquidity management tool. Its core breakthroughs are threefold:
First, separation of operational agent and objective—the PBOC directly participates in secondary-market treasury transactions as buyer, without supplanting the Ministry of Finance’s sovereign debt issuance function; instead, its dual anchors are “liquidity management” and “interest-rate guidance.”
Second, enhanced flexibility in maturity structure—unlike traditional instruments such as reverse repos or Medium-term Lending Facility (MLF) loans, which are constrained by fixed tenors, treasury trading can span the full yield curve (short-, medium-, and long-term), offering precise levers for yield-curve management.
Third, closed-loop feedback with fiscal policy—when the issuance pace of special-purpose treasury bonds accelerates, the PBOC can conduct offsetting buy/sell operations to dampen market volatility, thereby preventing interest-rate hikes triggered by fiscal expansion from exerting a crowding-out effect on the real economy.

This move directly addresses current macro-policy pain points: amid unresolved local government debt pressures and front-loaded local government special bond issuance, relying solely on reserve requirement ratio (RRR) cuts or MLF operations risks exacerbating liquidity stratification across the banking system. Treasury trading, by contrast, penetrates deep into the core of the bond market, enabling more efficient transmission from “loose money” to “broad credit.” Markets responded swiftly: In April, the 10-year treasury yield fell by 5 bps, while the 10Y–1Y yield spread widened by 12 bps—evidence of meaningful relief in medium- to long-term funding cost pressure.

Offshore RMB Breaks Through 6.8: A “Dual-Engine” Dynamic—Capital-Account Confidence Recovery Meets Trade Resilience

The CNH’s breach of the 6.8 level is no isolated exchange-rate fluctuation—it reflects the convergence of multiple fundamental forces. Underpinning this rally lies a clear “dual-engine” logic:
Engine One: Marginal Recovery in Capital-Account Confidence. Despite complex external conditions—including the EU’s designation of China as a “high-risk country” and its restriction on financing for Chinese inverter projects (exposing potential “decoupling” risks in green energy), and Japan’s possible deployment of USD 32 billion in a single month to counter yen depreciation (heightening expectations of competitive devaluation across Asia)—the RMB strengthened against the trend. This signals that international investors are reassessing the relative value of Chinese assets: On one hand, frequent high-level interactions between China and the U.S. (e.g., Foreign Minister Wang Yi’s meeting with the first bipartisan U.S. Congressional delegation under the Trump administration) have reinforced geopolitical “bottom-line thinking”; on the other, China’s Q1 GDP grew 5.3% year-on-year, and exports exceeded expectations—especially shipments to ASEAN (+12.7%) and Latin America (+18.1%), effectively offsetting soft demand from Europe and the U.S. A rational, “voting-with-feet” capital-account rebound is underway.

Engine Two: Unexpected Resilience in the Current Account Surplus. Customs data for April showed China’s foreign trade surplus reached USD 66.3 billion—its 12th consecutive month above USD 50 billion. More critically, its composition improved markedly: Exports of the “new three” sectors—new-energy vehicles, lithium batteries, and photovoltaic products—rose 28.5% year-on-year, accounting for 5.2% of total exports. This implies the surplus is no longer reliant on traditional labor-intensive industries, but instead rests on technological upgrading and irreplaceability within global supply chains. Such “high-quality surpluses” provide robust fundamental support for the exchange rate—and simultaneously weaken incentives for short-term capital outflows.

Asset Price Re-pricing Amid Dual-Track Momentum: Hong Kong Tech Leads, A-Share Growth Sustains

The synchronization of the two liquidity tracks is accelerating a shift in capital market pricing logic. CNH appreciation directly lowers the foreign-exchange cost for overseas investors holding RMB-denominated assets. Combined with the medium-to-long-term liquidity easing signaled by treasury trading, this is driving a transformation in northbound fund behavior: In April, northbound funds posted net inflows of RMB 32.7 billion—with Hong Kong Stock Connect funds achieving their highest monthly net buying since September 2023. Their top allocation targets were overwhelmingly concentrated in Hong Kong tech stocks: The Hang Seng Tech Index rose 3.06% in a single day, while heavyweight constituents—including Tencent, Meituan, and Xiaomi—averaged gains exceeding 4.2%, reflecting foreign investors’ re-evaluation of earnings visibility in “China’s new economy.”

For A-shares, the implications run deeper. First, treasury trading has effectively lowered medium- to long-term risk-free rates, significantly boosting the attractiveness of growth stocks’ valuation denominators. Second, RMB appreciation eases input costs for import-dependent firms (e.g., semiconductor equipment and high-end medical devices) and strengthens the domestic substitution thesis priced in RMB terms. Wind data shows that in April, the trailing-twelve-month (TTM) P/E ratios for the Shenwan Electronics, Computer Science, and Communications sectors rose 8.3%, 6.7%, and 5.1%, respectively—substantially outpacing the A-share market average. Notably, this style rotation is not driven by thematic speculation: It coincides with the release of mutual fund Q1 reports—active equity funds increased their TMT sector holdings to 24.6%, the highest level in three years—confirming institutional investors’ long-term strategic reallocation.

Risk Alert: Guard Against “Tool Overload” in Policy Coordination; External Uncertainties Remain

It is vital to recognize that while the dual-track dynamic is encouraging, it also harbors challenges. First, as a newly deployed instrument, rapid scaling of treasury trading could blur the boundary between fiscal and central bank functions—raising risks of market misinterpretation as “monetization of fiscal deficits.” Transparency and rule-based governance must therefore be urgently strengthened. Second, although CNH appreciation benefits capital markets, it dampens exporters’ willingness to convert foreign currency proceeds into RMB: In April, banks’ client FX conversion volume declined 3.2% year-on-year—warranting close monitoring of exporters’ adaptive strategies. Third, the external environment remains fundamentally unsettled—the EU’s green-trade barriers continue tightening, and the approaching U.S. presidential election may intensify anti-China rhetoric—both posing latent sources of disruption.

In summary, April’s dual-track macro liquidity momentum represents both a milestone in the evolution of China’s policy framework and a microcosm of the rebalancing between China’s endogenous economic momentum and external investor confidence. When treasury trading becomes a stabilizer—and RMB appreciation serves as a mirror of confidence—the capital market’s pricing of “high-quality development” truly begins. Going forward, key observation priorities should shift from isolated data points to: (i) the depth of policy coordination (e.g., timing alignment between special treasury bond issuance and PBOC treasury trading); (ii) structural shifts in capital flows (e.g., whether northbound funds sustain their tilt toward hard-tech sectors); and (iii) whether the RMB exchange rate can establish a new equilibrium range between 6.75 and 6.85—this will be the true litmus test of the dual-track mechanism’s sustainability.
