Weakening Bretton Woods II recycling of East Asian trade surpluses: Deutsche Bank sees weaker East Asian dollar recycling reshaping global rates and FX adjustment

Overview

Deutsche Bank examines why today’s large trade imbalances coincide with rising global yields, a stronger RMB and greater currency volatility. Its central argument is that the Bretton Woods II mechanism—where East Asian surpluses were recycled into dollar safe assets, especially US Treasuries—has weakened materially even though the underlying surpluses persist.

Core views

The report distinguishes today’s trade imbalance from the 2000s by focusing on the financial mechanism that previously absorbed it. Under Bretton Woods II, export-led Asian economies accumulated foreign exchange and reinvested it in the financial markets of the US, Europe and Japan, particularly dollar safe assets. This capital loop financed the US current-account deficit and, in Deutsche Bank’s account, helped keep global long-term real interest rates low. China exemplified the process: its official FX reserves rose from USD166bn at the end of 2000 to a USD4trn peak in 2014 as the PBOC bought export-related foreign exchange and placed reserve assets largely in liquid dollar securities. Official reserve accumulation ended after 2014, but the report argues that dollar recycling did not immediately disappear; it shifted from the PBOC to China’s private sector. China’s reserves fell to USD3.01trn by end-2016, almost USD1trn below their peak. Yet Chinese onshore banks and other sectors increased external deposits and debt holdings by USD1trn between 2015 and 2025, according to China’s international investment position statistics. Deutsche Bank also points to the gap between China’s trade balance and banks’ FX settlement balance as a proxy for roughly USD5trn of cumulative private outflows during 2015-25, while noting that this likely understates total overseas holdings because offshore Chinese assets are excluded. From 2022 through the first half of 2025, this private-sector mechanism still helped contain RMB appreciation despite China’s expanding trade surplus. The report estimates China’s annual goods-and-services trade surplus at about USD500bn in 2022-24, rising to USD800bn in 2025. Chinese companies continued to convert export proceeds into overseas assets, producing persistent client FX settlement deficits and growing corporate offshore dollar deposits. Deutsche Bank’s mechanism is that recycling these proceeds into US financial markets supported the dollar, while a weak RMB in turn reinforced Chinese exports. The turning point came as the RMB began to strengthen in mid-2025. By the fourth quarter, exporters faced potential currency losses that reduced the appeal of higher dollar yields and encouraged hedging or FX conversion. Client FX settlement exceeded sales by USD222bn in H2 2025, reversing a USD25bn net deficit in H1; the settlement surplus then rose to USD338bn in January-August 2026. The report interprets this as evidence that companies became more willing to sell foreign currency and had little appetite to keep accumulating FX assets. Chinese banks initially absorbed some of the dollars that companies no longer wished to hold. Their total external assets rose from USD1.61trn at end-2024 to USD1.98trn at end-2025, an increase of USD368bn. Dollar assets increased by USD155bn to USD970bn, rebuilding much of the decline from USD1.0trn at end-2021 to USD815bn at end-2024. This temporary bank absorption helped explain why more active corporate FX conversion could coexist with limited PBOC purchases and only moderate RMB appreciation. That bank channel also weakened by Q1 2026. Although banks’ external assets rose by USD131bn in the quarter, dollar-denominated assets increased by only USD7bn; RMB assets accounted for USD78bn and other currencies USD46bn, meaning about 95% of the increase was outside dollars. Deutsche Bank attributes the retreat from additional dollar holdings to banks having replenished prior losses, the risk of RMB appreciation on unhedged exposure, and greater opportunities to lend to non-residents in RMB. With the PBOC no longer accumulating reserves, companies reducing dollar accumulation from H2 2025, and banks adding little by Q1 2026, the report concludes that China’s large surplus has become harder to absorb into dollar assets under the former model. The shift extends beyond mainland China. Korea and Taiwan still channel savings into US markets, but much less into Treasuries: from January 2025 to June 2026, Korean residents bought net USD109bn of US equities while selling USD6bn of Treasuries. Taiwanese residents bought USD17bn of US equities, USD18bn of agency bonds and USD14bn of corporate bonds, versus USD3bn of Treasuries. The report also notes that China’s gold imports more than doubled year on year in US-dollar terms in H1 2026 and accounted for 10% of total imports, while Korean and Taiwanese gold imports increased as well. Deutsche Bank links the reduced demand for dollar safe assets to higher US Treasury yields alongside yields in other major markets, low Chinese interest rates, strong equity-market performance and depreciation of major currencies against gold. It does not reach a definitive conclusion on whether Bretton Woods II has ended or is only temporarily disrupted. However, it considers it relatively certain that global trade imbalances will persist, while the stabilizing financing conditions associated with the old system have weakened materially and are unlikely to recover soon. The institution therefore expects elevated global interest rates and high exchange-rate volatility to persist, drawing a historical parallel with the unsettled period after the original Bretton Woods system collapsed.

Analysis framework

The report compares the 2000s Bretton Woods II capital-recycling loop with post-2014 Chinese private-sector flows and the 2025-26 shift in corporate and bank FX behavior. It uses reserve data, international investment position data, bank FX settlement, external-asset composition and US TIC flow data to trace where East Asian trade surpluses are being invested and how that affects demand for dollar safe assets.

Methodology notes

• Macroeconomics

  Bretton Woods II surplus-recycling mechanism

  The report uses the Bretton Woods II concept to explain how Asian trade surpluses were recycled into dollar safe assets and how the weakening of that loop shifts adjustment toward yields and exchange rates.

  Demand for US dollar safe assets

  The report treats official and private Asian purchases of dollar assets as a source of demand that historically helped finance US deficits and restrain long-term rates; lower demand leaves more pressure on market prices.

Key data

• China official FX reservesUSD166bn at end-2000; USD4trn peak in 2014; USD3.01trn at end-2016Reserves rose under the original official recycling mechanism, then fell by almost USD1trn from the 2014 peak.
• Chinese onshore external deposits and debtUSD1trn increase between 2015 and 2025Evidence that private-sector external asset accumulation continued after reserve growth stopped.
• Estimated private FX outflowsRoughly USD5trn cumulatively during 2015-2025Proxy inferred from the persistent gap between China’s trade balance and banks’ FX settlement balance.
• China goods-and-services trade surplusApproximately USD500bn annually in 2022-24; USD800bn in 2025The surplus expanded while companies continued placing export receipts in overseas assets.
• Corporate client FX settlement balanceUSD25bn net deficit in H1 2025; USD222bn surplus in H2 2025; USD338bn surplus in January-August 2026Shows the reported reversal toward greater corporate foreign-currency conversion.
• Chinese banks' external assetsUSD1.61trn at end-2024; USD1.98trn at end-2025The USD368bn increase initially allowed banks to absorb part of the corporate shift away from dollar holdings.
• Chinese banks' Q1 2026 external-asset increaseUSD131bn total; USD7bn in dollar assets; USD78bn in RMB assets; USD46bn in other currenciesAbout 95% of the increase was in non-dollar assets, indicating a sharp slowdown in bank dollar accumulation.
• Korean US portfolio flowsUSD109bn net purchases of US equities and USD6bn sales of Treasuries, January 2025-June 2026Illustrates a shift from Treasury demand toward equities.
• Taiwanese US portfolio flowsUSD17bn US equities, USD18bn agency bonds, USD14bn corporate bonds and USD3bn TreasuriesShows US-market investment continuing but with limited Treasury purchases.
• China gold importsMore than doubled year on year in USD terms in H1 2026; 10% of total importsThe report identifies gold as another destination for surplus savings.

Impact & implications

The report argues that persistent East Asian surpluses no longer provide the same dependable demand for US Treasuries and other dollar safe assets. It links this change to higher global yields, more exchange-rate adjustment—including RMB strength—and a more volatile international monetary environment.
