US Dollar Collapse Timeline: When Will the Dollar Lose

Key Findings

• The US dollar’s share of global foreign exchange reserves has steadily declined from 71.2% in 1999 to 58.4% as of Q4 2023, according to IMF COFER data.
• BRICS nations have accelerated efforts to develop an alternative reserve currency, with proposals for a commodity-backed “BRICS currency” tabled in August 2023 and pilot projects anticipated by 2026.
• The Chinese yuan’s share of global reserves remains modest at 2.3% in 2023, but its use in cross-border settlements and energy trade has grown over 300% since 2018.
• Scenarios for a US dollar reserve status loss by 2035 range from low (10% probability) to moderate (35% probability), with sharp consequences for US borrowing costs—potentially raising Treasury yields by 100-200 basis points.
• Historical precedents, including the British pound’s decline (from 64% of reserves in 1945 to under 10% by 1975), suggest reserve currency transitions are gradual but can accelerate following major geopolitical or economic shocks.

The US Dollar’s Reserve Status: Current Data and Trends

The US dollar remains the world’s dominant reserve currency, but its supremacy is no longer absolute. IMF COFER (Currency Composition of Official Foreign Exchange Reserves) data shows the dollar’s share of global reserves fell from 71.2% in 1999 to 58.4% at the end of 2023. In absolute terms, this equates to $6.5 trillion of a $11.1 trillion global reserve pool as of December 2023 (IMF COFER, Q4 2023).

The decline accelerated after 2014, coinciding with sanctions against Russia and the expansion of US extraterritorial financial controls. Central banks, particularly in emerging markets, have rebalanced portfolios to include more gold, the euro, yuan, and other currencies. For example, global gold reserves held by central banks increased by 1,136 metric tons in 2022—the largest single-year jump since 1967 (World Gold Council, 2023).

The euro’s share has remained roughly stable, standing at 20.1% in Q4 2023, while the Japanese yen and British pound account for 5.5% and 4.7% respectively. The Chinese yuan, though heavily promoted by Beijing, holds just 2.3% of reserves (IMF COFER).

The slow, persistent erosion of the dollar’s share reflects both diversification strategies and growing skepticism about the long-term safety of US assets, especially in the context of rising US debt, now at $34.7 trillion (US Treasury, April 2024), and recurring debt ceiling crises.

BRICS Currency Proposals and the Challenge to Dollar Dominance

Since 2022, BRICS nations (Brazil, Russia, India, China, South Africa, with new members including Saudi Arabia and UAE in 2024) have intensified efforts to reduce reliance on the US dollar. At the Johannesburg BRICS Summit (August 2023), member states agreed to explore a new reserve currency, potentially backed by gold or a basket of commodities.

Russian officials, including Sergei Glazyev (EAEU, April 2023), proposed a “BRICS currency” pilot by 2026, designed for intra-bloc trade settlement. The proposal envisions a digital currency tied to a basket of member currencies and key commodities (notably oil and gold). While technical and political hurdles are substantial, the scale of BRICS—now accounting for 32% of global GDP and 42% of the world’s population (World Bank, 2024)—gives the initiative geopolitical weight.

India and Brazil remain cautious, preferring to expand bilateral local currency settlements first. However, Russia, China, and the Gulf states have accelerated de-dollarization. Over 60% of Russia-China trade was settled in yuan or rubles by Q1 2024 (Bank of Russia).

The likely path forward is gradual: pilot projects in trade settlement by 2026, followed by limited reserve adoption by central banks, particularly those within the BRICS+ framework. Widespread global reserve uptake before 2030 remains unlikely, given convertibility, liquidity, and trust constraints.

Yuan Internationalization: Progress and Barriers

The Chinese yuan (renminbi) has made significant strides in international usage, but it remains far from challenging the dollar’s reserve status. According to SWIFT RMB Tracker (March 2024), the yuan’s share of international payments reached 4.7%, up from 2.2% in 2018—a doubling in six years. This rise is driven by Beijing’s aggressive promotion of yuan-denominated trade, especially with Russia, MENA, and ASEAN nations.

China’s Cross-Border Interbank Payment System (CIPS) processed 123 trillion yuan ($17.6 trillion) in transactions in 2023, up 36% year-on-year (PBOC, February 2024). Bilateral yuan swap lines now cover 40 countries, including major economies such as Brazil, Saudi Arabia, and the EU.

However, the yuan faces core barriers:

• Capital controls: China restricts cross-border capital flows, limiting liquidity and trust for reserve managers.
• Lack of market depth: The offshore yuan (CNH) market is less liquid than US Treasuries.
• Policy opacity: Concerns over arbitrary regulatory interventions persist.

Despite these obstacles, yuan-denominated oil contracts on the Shanghai International Energy Exchange have surpassed 8% of global oil futures volume as of April 2024 (SIEE). Saudi Aramco and ADNOC began accepting partial yuan payments for oil in 2023, signaling a shift in the petrodollar regime.

The Petrodollar Erosion: Impact on Reserve Flows

The petrodollar system, established in the 1970s, linked global oil trade to US dollar settlement. This arrangement has anchored global demand for US assets, as oil exporters recycled surpluses into Treasuries and other dollar securities.

Recent trends show cracks in this system:

• Saudi Arabia's diversification: In June 2023, Riyadh allowed oil contracts with China to be settled in yuan for the first time, accounting for 5% of bilateral trade ($6.3 billion) in H2 2023 (Saudi Ministry of Finance).
• UAE-India rupee oil trade: In August 2023, India and the UAE completed their first rupee-denominated oil trade, worth $350 million.
• Global oil settlement in non-dollar currencies: According to JP Morgan (February 2024), non-dollar settlements constituted ~15% of global oil trade in 2023, up from under 3% in 2015.

Should this trend accelerate, it could materially reduce structural demand for US Treasuries, increasing US external financing costs. A 10 percentage point reduction in petrodollar recycling could raise US 10-year Treasury yields by 40-60 basis points, according to BIS research (BIS Bulletin No. 72, 2022).

Scenario Analysis: US Dollar Collapse Timeline, 2026-2035

The risk of a sudden “US dollar collapse” is overstated in most commentary, but a measured erosion of reserve status is plausible over the 2026-2035 horizon. Three scenarios frame the possible timeline:

1. Status Quo Extension (Probability: 55%)

• Timeline: Dollar share remains above 50% through 2035.
• Drivers: US remains global safe haven; BRICS alternatives fail to scale; euro and yuan limited by structural flaws.
• Consequences: US borrowing costs remain contained (10-year yields stay below 5%). Reserve diversification slow.

2. Accelerated Diversification (Probability: 35%)

• Timeline: Dollar share falls to 45-50% by 2030, 35-40% by 2035.
• Drivers: BRICS currency pilots gain traction post-2026; yuan’s internationalization advances; major oil producers settle >30% of exports in non-dollar currencies by 2030.
• Consequences: US 10-year yields rise by 100-200 basis points, widening fiscal deficits by $400-$700 billion annually by 2032 (CBO projections, adjusted for higher rates). Emerging markets increase allocation to yuan and gold.

3. Crisis-Driven Displacement (Probability: 10%)

• Timeline: Dollar share falls below 30% by 2032, reserve status effectively lost.
• Drivers: Major US debt default, geopolitical rupture (e.g., Taiwan conflict), or global financial crisis triggers rapid diversification.
• Consequences: US borrowing costs spike >7%, Treasury market volatility surges, risk of global liquidity shock.

Most credible estimates, including Gita Gopinath (IMF, April 2023) and Michael Pettis (Carnegie, March 2024), view scenario 2 as increasingly likely if current trends persist—but sudden collapse remains a tail risk contingent on exogenous shocks.

US Borrowing Costs and Fiscal Implications

The US government benefits from the “exorbitant privilege” of issuing debt in its own currency, with foreign central banks holding $6.5 trillion in Treasuries as of March 2024 (US Treasury TIC data). A loss of reserve status would erode this privilege, forcing the US to offer higher yields to attract buyers.

A 100-basis-point increase in average Treasury yields would add $375 billion to annual debt service costs by 2030, given debt projections of $37.5 trillion (CBO, May 2024). If foreign demand dropped by half, the Congressional Budget Office estimates the US deficit would widen by 2.1% of GDP annually.

Secondary effects include:

• Dollar depreciation: Loss of reserve demand would weaken the dollar, raising import prices and fueling inflation.
• Asset repricing: US equities and real estate could face capital outflows, raising risk premiums.
• Global spillovers: Emerging markets exposed to dollar-denominated debt would experience tighter financial conditions.

Moody’s and Fitch assign a low probability (<5%) to a sudden loss of reserve status absent a sovereign default or major policy error.

Historical Analog: The British Pound’s Decline

The transition from pound sterling to the dollar as the world’s reserve currency offers instructive parallels. In 1945, sterling accounted for 64% of global reserves; by 1955, the figure had dropped to 44%. The process accelerated following the Suez Crisis (1956), with sterling’s share falling below 10% by 1975 (Eichengreen, “Exorbitant Privilege”, 2011).

Key lessons:

• Gradual transitions: Reserve status erosion typically spans decades, not years.
• Geopolitical shocks as accelerants: Major crises (e.g., Suez, US sanctions) can trigger rapid shifts in central bank portfolios.
• Network effects: Inertia favors incumbents until alternatives offer comparable safety, liquidity, and depth.

The dollar’s global role is more deeply entrenched than sterling ever was. US Treasuries remain the deepest, most liquid market, with $1.1 trillion daily turnover (Fed, March 2024).

Counter-Arguments: Why Dollar Durability Remains High

Despite mounting challenges, the dollar’s durability is underpinned by structural advantages:

• Liquidity and depth: US Treasuries and dollar-denominated markets dwarf alternatives in size and liquidity.
• Rule of law: The US legal system, despite political polarization, offers stronger property rights and contract enforcement than BRICS peers.
• Network effects: Over 85% of global FX transactions involve the dollar (BIS Triennial Survey, October 2022).
• Lack of credible alternatives: The euro is hampered by incomplete fiscal union; the yuan by capital controls; BRICS currency efforts remain nascent.

These factors suggest a gradual, managed decline in dollar share—rather than an abrupt collapse—is the most probable outcome barring exogenous shocks.

What to Watch

• IMF COFER updates: Quarterly data for 2024-2026 will reveal the pace of reserve diversification.
• BRICS currency pilots: Watch for official pilot launches, especially in trade settlement, by late 2026.
• Yuan internationalization milestones: Monitor new swap lines, cross-border CIPS volumes, and yuan-denominated commodity contracts.
• Petrodollar erosion: Track the share of global oil and gas trade settled in non-dollar currencies, with key inflection points likely in 2026 and 2030.
• US fiscal and political shocks: Debt ceiling standoffs, sovereign rating downgrades, or a major geopolitical conflict could accelerate reserve status loss.

Frequently Asked Questions

Q1: How quickly could the US dollar lose its reserve currency status? Transitions are typically gradual. The dollar’s share of global reserves fell from 71% (1999) to 58% (2023). Even in an accelerated scenario, falling below 40% by 2035 is plausible, with complete loss of reserve status highly unlikely before 2040 absent a major crisis.

Q2: What would happen to US borrowing costs if the dollar lost reserve status? Loss of reserve demand would force the US to offer higher yields to attract buyers. A 100-200 basis point rise in Treasury yields could add $375-$750 billion to annual debt service costs by 2030, crowding out other fiscal priorities and raising inflation risk.

Q3: Can the BRICS or Chinese yuan realistically replace the dollar? Neither is poised to fully replace the dollar in the next decade. The yuan faces capital controls and trust issues; BRICS currency projects are experimental. However, both could erode the dollar’s share, especially in bilateral trade and regional reserves, accelerating the trend toward a more multipolar reserve system.
