From Tokyo to Beijing: How China's Cheap Capital is Reshaping Global Liquidity

China's Japanification Through Rates

The thesis should be evaluated across three distinct layers. First are official policy rates, where the comparison remains clear: the PBoC's principal policy rate was 1.4 percent in June and July 2026, while the BoJ moved to 1.0 percent in June 2026 after standing at 0.75 percent in March.^[10,18,19] Second are onshore money-market rates, where China's 1-year SHIBOR at 1.628 percent indicates that selected RMB funding tenors now screen as highly competitive against Japanese benchmarks and reinforce the market perception of a Chinese easing bias relative to Japan's normalization path.^[29,19]

Third are effective cross-border financing costs, which matter most for real-world funding behavior. These include the all-in economics available through panda bond issuance, dim sum bonds, trade-finance lines, offshore RMB borrowing, and official liquidity facilities that support cross-border credit intermediation.^[4,7,16] This third layer is where China's role is changing most materially, because the cost of funding is becoming increasingly relevant only insofar as borrowers can access scalable settlement, hedging, and refinancing infrastructure in RMB.^[4,26]

A fourth layer belongs in this framework: the FX-hedged cost actually realized by an offshore borrower. Section 06 develops it in full.

Usability, not dominance, is the bar the renminbi has to clear

Japan's long-standing role in global finance rested on more than low nominal rates. It depended on open capital mobility, institutional trust, large domestic savings pools, and deep offshore acceptance of the yen as a funding currency.^[26] China does not yet replicate that system. However, lower RMB funding costs now coincide with the world's largest merchandise trade footprint, a policy push for RMB internationalisation, and a more mature ecosystem for issuance, settlement, and liquidity provision.^[4,26]

That combination changes the strategic significance of low Chinese rates. A currency does not need to displace the dollar or match the yen's historical carry-trade role to matter for global liquidity creation. It needs to become sufficiently usable in trade finance, credit intermediation, and bond funding that a growing set of borrowers rationally chooses it at the margin.^[4,16,26] On that measure, the renminbi is gaining traction.

Trade Finance Adoption

Trade finance is the strongest channel through which the RMB's lower-cost profile is being externalized. SWIFT's January 2026 RMB Tracker reported that the renminbi ranked sixth among global payment currencies in December 2025 with a 2.73 percent share by value, while its role in trade finance remained more substantial than its headline payments share alone would suggest.^[26] This is an important data point because it confirms that RMB usage in cross-border commercial activity has reached functional scale despite China's incomplete capital-account liberalization.^[26]

The implication is practical rather than symbolic. Where China sits at the center of supply chains, commodity trade, and bilateral commercial relationships, RMB trade-finance usage can expand without requiring the renminbi to become a fully open reserve currency.^[26,16,4] In effect, trade settlement is creating its own financing flywheel: the more corporates invoice and settle in RMB, the easier it becomes for banks to extend RMB working-capital lines, supplier credit, and other short-duration financing products.^[16,26]

Quantifying the settlement backbone

This flywheel has a measurable settlement backbone. China's Cross-Border Interbank Payment System (CIPS) had grown to 1,791 participating financial institutions by the end of the first quarter of 2026, including 194 direct participants spanning 124 countries and regions, up sharply from 19 direct and 176 indirect participants at system launch.^[40] Average daily transaction volume set a record in March 2026 at roughly RMB 920.5 billion (about $133.5 billion), up 20 percent year on year, with indirect participants outside mainland China now accounting for 65 percent of system membership, up from 57 percent in 2020.^[40] This is the plumbing that makes the trade-finance flywheel scalable rather than anecdotal, and it belongs alongside the SWIFT payments-share figure as primary evidence for this pillar.

Fixed-Income Ecosystem

The second pillar is the rapid development of an increasingly credible RMB fixed-income funding ecosystem. Standard Chartered noted that panda and dim sum bonds are evolving into a deeper, two-way financing market, while NAFMII-registered panda bond issuance reached RMB163.31 billion in 2025, up 15.6 percent year on year.^[4] China Daily further reported that panda bond issuance reached a record 88.24 billion yuan in the first quarter of 2026, with deal count up 87.5 percent and issuance volume up 101.45 percent from a year earlier.^[7]

These data matter because they move the discussion from abstract currency internationalisation to measurable funding access. Panda bonds allow foreign sovereigns, multilaterals, and financial institutions to tap China's domestic liquidity pool directly, while dim sum bonds expand offshore RMB funding channels for both Chinese and international issuers.^[4,7] As these markets deepen, the renminbi becomes more usable as a liability currency even where capital-account frictions remain in place.^[4]

Parallels with the Yen

The comparable yen-side market deserves a mention. Samurai bond issuance by foreign borrowers has itself been booming, and that boom has pushed yen cross-currency swap costs higher, according to reporting in the Japan Times, a supply-driven dynamic independently narrowing the yen's cost advantage even before the BoJ's own tightening path is factored in.^[32] Alphabet's move to issue yen-denominated global bonds in 2026 to help fund AI-related capital expenditure shows that large, well-rated borrowers still see value in locking in yen funding ahead of further BoJ hikes, a useful reminder that the yen has not been priced out of the market. It remains competitive, just visibly less advantaged than it was a year ago.^[32]

Official Swap and Credit Intermediation

The third pillar is official and quasi-official cross-border liquidity support. Bank of China publicized a trade-related financing transaction in Singapore funded through the Monetary Authority of Singapore's RMB Facility under the bilateral swap framework.^[16] This is significant not because a single transaction changes the global system, but because it demonstrates how bilateral swap lines and associated facilities are being operationalized to support actual RMB credit creation beyond mainland China.^[16]

This channel deserves closer attention than it usually receives. Official swap frameworks, when tied to trade finance and working-capital usage, can function as transmission mechanisms through which policy-backed RMB liquidity reaches offshore borrowers in a controlled but expanding manner.^[16,4] While this remains far from a globally fungible eurodollar-style network, it strengthens the institutional scaffolding behind the renminbi's international financing role.^[4]

The Missing Layer: FX-Hedged Funding Costs

Every headline comparison in this note so far (PBoC 1.4 percent versus BoJ 1.0 percent, SHIBOR 1.628 percent, panda bond coupons) is a nominal, unhedged rate, and that gap deserves its own section. None of them is the number a global borrower without natural RMB revenue actually pays, because that borrower typically swaps proceeds back into dollars or another home currency and bears the cost of that hedge.

For offshore RMB, the relevant figure is the CNH-implied yield, derived from USD/CNH forward points under covered interest parity, which functions as the de facto benchmark for offshore RMB funding cost.^[39] Two features of this market matter for the thesis. First, the CNH-implied yield reflects offshore USD liquidity conditions as much as it reflects PBoC policy: when offshore dollar funding tightens, the RMB-USD swap point moves and the implied yield can rise independent of anything happening onshore.^[39] Second, the implied yield rises sharply when the market prices in RMB depreciation, because the forward curve embeds expected currency weakness as well as the interest-rate differential.^[39] A borrower who locks in a "cheap" onshore-referenced RMB rate but hedges the currency risk can end up paying a materially different effective cost than the SHIBOR or panda-bond coupon alone would suggest, particularly during periods when the market expects yuan softness.

That claim describes the growing addressable market for RMB financing among naturally matched borrowers, the trade-finance and supply-chain borrowers described in Section 03, not a claim that RMB funding is unconditionally cheaper than yen funding for any global borrower on a hedged basis. For borrowers without a natural RMB match, the fair comparison is CNH-implied yield versus JPY cross-currency swap cost, not policy rate versus policy rate. Independent, current CNH cross-currency basis levels were not obtainable through the sources available and should be verified against a live data terminal before being used for any specific funding decision.

Comparative Credit Standing

A rigorous comparison of "cheap funding" should also address counterparty and sovereign credit risk. On this dimension the two sovereigns are closer than intuition might suggest.

The two sovereigns therefore sit at broadly comparable investment-grade levels. The funding-cost differential documented in this note is better explained by the divergent monetary-policy cycles (China easing, Japan normalizing) and by structural demand-and-supply conditions in each domestic bond market, including the property-and-local-debt overhang discussed next, than by a gap in sovereign credit risk. That supports the thesis rather than weakens it: the rate convergence looks like a genuine cyclical and structural phenomenon, not an artifact of a closing credit-risk gap.

Counter-Thesis: Is This Cyclical, Not Structural?

The most serious challenge to this thesis is that China's currently ultra-accommodative funding conditions are substantially a symptom of domestic economic stress rather than an independent structural advantage, and could reverse (or deteriorate further in a disorderly way) rather than persist as a stable new equilibrium.

Two readings follow, and this note is explicit that both are live possibilities rather than picking one. Under the first, China's low funding costs persist or deepen because the property and local-debt overhang takes years to work through, in which case the financing-cost advantage documented here is durable but is arguably a symptom of a weaker Chinese growth trajectory that investors should not read as an unambiguously bullish signal for China risk generally. Under the second, a stabilization of property markets and local-government balance sheets (aided by fiscal support measures already underway, including a headline deficit at or above 4 percent of GDP and continued special-purpose bond issuance for debt restructuring) allows the PBoC to normalize policy over time, which would narrow or close the funding-cost gap with Japan just as the trade-finance and bond-market infrastructure built during the low-rate period reaches critical mass.^[43]

Either way, readers should treat the rate crossover as a signal of Chinese monetary and cyclical conditions first, and a structural RMB-internationalization signal second. The two are related, but they should not be conflated. The BoJ's own 30–31 July 2026 policy meeting, at which the central bank is widely expected to hold at 1.0 percent while assessing the impact of its June hike, is itself a reminder that the Japan side of this comparison is also a live, moving cyclical process rather than a settled endpoint.^[45]

What has not changed

The note must be explicit about what has not changed. China has not yet displaced Japan as the world's most freely deployable low-cost funding base, because the renminbi remains subject to capital-account controls, convertibility limits, and a materially less elastic offshore liquidity pool than either the yen or the dollar.^[4,26] These constraints reduce arbitrage efficiency, complicate repatriation and hedging flexibility, and limit the extent to which RMB funding can scale globally without policy mediation.^[4]

Offshore pool depth, quantified

The scale of that offshore pool is worth quantifying rather than asserting. Hong Kong's offshore RMB deposit and certificate-of-deposit pool (the largest in the world) stood at roughly RMB 1.04 trillion as of mid-2025, having grown from about RMB 90 billion in 2010; it also contracted modestly over the first seven months of 2025 even as the broader RMB-internationalization narrative advanced.^[46] That is genuine growth over fifteen years, but it remains a small fraction of global short-term dollar funding markets and is not yet a deep enough pool to support RMB funding at global dollar- or yen-market scale without continued official facility support, such as the HKMA's RMB Business Facility.^[46]

A second qualification is definitional. The official policy-rate crossover remains prospective, not realized: the PBoC's 1.4 percent policy rate still stood above the BoJ's 1.0 percent rate in mid-2026 even though selected Chinese market rates and issuance channels can already look cheaper on a maturity-matched or use-case-adjusted basis.^[10,19,29] A third qualification is geographic scope. The RMB's financing role may become systemically meaningful in Asia and the emerging world well before it becomes globally equivalent to yen or dollar balance-sheet liquidity.^[26,4]

The reserve-currency gap

A fourth qualification is that the reserve-currency gap between the two currencies remains wide and is not currently closing. IMF COFER data show the renminbi's share of allocated global foreign-exchange reserves at 1.95 percent in the fourth quarter of 2025, versus the yen's 5.84 percent in the same quarter, which itself fell to 5.44 percent in the first quarter of 2026.^[47] Both currencies remain far behind the dollar's roughly 57 percent share and the euro's roughly 20 percent share.^[47]

The practical implication is that this note's thesis is about flow (transactional and financing usage), not about stock. Central banks and reserve managers are not treating the renminbi as a yen-equivalent store of value, even as corporates and banks increasingly treat it as a yen-competitive financing currency. That distinction should discipline how far the thesis is extrapolated.

Four practical implications

Four practical implications follow. First, cross-border borrowers with natural China revenue, procurement, or trade exposure should increasingly evaluate RMB liabilities as part of funding optimization rather than treat the currency solely as a settlement medium.^[4,7,16] Second, regional and emerging-market banks should be expected to expand RMB-denominated trade-finance and working-capital books as customer demand, policy support, and settlement infrastructure continue to deepen.^[16,26]

Third, macro investors should assign greater weight to Chinese liquidity conditions in judging regional credit creation and the future composition of Asia-linked funding markets. The renminbi need not become dominant to become disruptive at the margin; it only needs to become sufficiently cheap, scalable, and operationally usable for a wider set of issuers and intermediaries.^[4,26]

Fourth, any borrower or allocator acting on this thesis without a natural RMB revenue match should price the decision off the CNH-implied yield and current cross-currency basis, not off SHIBOR or the panda-bond coupon, and should treat China's current funding advantage as conditioned on the property-and-local-debt cycle discussed in Section 08 rather than as a fixed structural discount that is safe to assume forward.^[39,43]

What to track

• PBoC 7-day reverse repo rate and related liquidity operations, including the new overnight reverse repo facility introduced June 2026, as the clearest signal of China's formal policy stance.^[10,8,44]
• BoJ policy-rate decisions and money-market guidance, including the 30–31 July 2026 meeting outcome, which determine whether Japan remains on a normalization path.^[18,19,45]
• 1-year SHIBOR and related RMB money-market tenors, which show whether the market-rate crossover is broadening or proving durable.^[28,29]
• USD/CNH forward points and the CNH-implied yield, which capture the FX-hedged funding cost that onshore rate comparisons omit.^[39]
• Panda and dim sum bond issuance, alongside Samurai bond issuance and yen cross-currency swap costs, as comparative evidence of cross-border funding adoption on both sides of the thesis.^[4,7,32]
• SWIFT RMB payments and trade-finance shares, alongside CIPS participant counts and settlement volumes, as measures of whether transaction usage is translating into scalable settlement infrastructure.^[26,40]
• Bilateral swap-line activation and offshore RMB facility usage, which reveal whether official liquidity channels are supporting scalable external credit creation.^[16]
• Hong Kong's offshore RMB deposit and CD pool size, and IMF COFER reserve shares for RMB and JPY, as measures of whether offshore liquidity depth and store-of-value adoption are keeping pace with the financing-usage narrative.^[46,47]
• China's property-sector and local-government / LGFV debt indicators, as the leading signal of whether current PBoC accommodation is cyclical and reversible or likely to persist.^[43]

A market-architecture change, held to a higher analytical standard

The more precise institutional conclusion is that China has not yet replaced Japan across every definition of cheap funding, but it is increasingly challenging Japan's historical primacy in the segments of financing that matter most for Asia-linked trade, bond issuance, and cross-border credit formation.^[10,19,29,4] That is a meaningful structural shift in global liquidity, and one that deserves to be tracked as a market-architecture change rather than dismissed as a narrow rates anomaly.^[4,26,16]

Readers should weigh that both sovereigns carry comparable investment-grade credit ratings, that the reserve-currency gap between the RMB and the yen remains wide and is not currently closing, and that current Chinese policy accommodation is entangled with a property-and-local-debt adjustment whose resolution path (smooth normalization versus prolonged stress) will materially shape whether today's funding-cost advantage persists.^{[41,42,47,43]}
