Could cryptocurrencies or SDRs replace the US dollar after a reset?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
A wholesale replacement of the US dollar by either private cryptocurrencies or an SDR-based instrument is not supported by current mainstream analysis: experts and major institutions say there is “no credible alternative” to the dollar now, and SDRs are an IMF reserve asset—not a currency in private hands—requiring major institutional changes to play that role [1] [2]. Policymakers and markets are discussing digital forms of reserve assets (e‑SDR, crypto-SDR proposals), but those remain proposals or experiments and would require IMF governance changes and buy‑in from sovereigns and central banks to matter [3] [4] [5].
1. Why the dollar remains dominant — and where pressure is coming from
The dollar still sits at the centre of global finance: it is the most-used currency for trade and the main vehicle for official reserves, Treasury markets and cross‑border payments, and analysts note that any shift away would be gradual and contested [6] [7]. That dominance is under pressure: commentators document a material decline in dollar metrics in 2024–25 and rising political and fiscal risks in the US that have weakened confidence and contributed to noticeable depreciation episodes in 2025 [6] [8].
2. Cryptocurrencies: technical novelty, limited institutional acceptance
Private cryptocurrencies offer some advantages for payments and transparency, but leading economists and institutions at Davos and in mainstream reporting do not expect Bitcoin or similar private tokens to replace state‑anchored currencies in the near‑ or medium‑term [9]. Market stories and new coins (e.g., SedraCoin) show crypto activity but do not change the core constraint: private tokens lack the legal‑tender status, deep government‑backed liquidity and the institutional plumbing that sustain a global reserve currency [10] [11].
3. SDRs and the IMF route: an institutional not a market shortcut
SDRs are an IMF unit of account and reserve asset, not a currency that private actors currently hold or spend; expanding SDRs’ role would require IMF votes and approvals—the creation of new allocations needs 85% of IMF SDR‑Department votes—and changes in which entities may hold them [5] [2]. Proposals to turn SDRs into a digital settlement token (e‑SDR, “IMFcoin” / eSDR concepts) have been floated by scholars, think‑tanks and the IMF’s leadership historically, but they remain conceptual and would require large‑scale cooperation among central banks and legal changes to matter [12] [3] [13].
4. Practical barriers to a sudden “reset” replacing the dollar
A “reset” that overnight replaces the dollar is not documented in authoritative sources; instead, studies and banks argue any transition would be gradual and hinge on liquidity, safe assets, and trust in institutions that issue the replacement [1] [14]. The global system holds trillions of dollars in Treasuries and banknotes abroad; that stock of assets, and the network of contracts and invoicing denominated in dollars, cannot be rewired quickly without severe dislocation [7] [8].
5. What e‑SDR or a “crypto‑SDR” would change — and what it would not
Digital SDR concepts (e‑SDR, c‑SDR) promise lower FX costs for central banks, programmable flows for development goals, and a stable unit tied to a currency basket; OMFIF and project proposals highlight potential cross‑border settlement uses for central banks [3] [15]. Those concepts, however, would not automatically confer private‑sector usability or legal tender status: the IMF’s SDR valuation is a basket of currencies and SDRs remain a claim among official holders unless governance is altered [2] [4].
6. Competing perspectives and the politics behind them
Market strategists and banks note de‑dollarisation trends and foresee slower dollar use over years, but they also emphasise that “no credible alternative” exists today [1] [6]. Geopolitical actors pushing national‑currency invoicing or BRICS coordination present a political challenge, but mainstream financial institutions and central banks stress practical limits to rapid displacement [16] [14]. Proposals to create IMF‑linked digital reserves carry implicit agendas: IMF/central‑bank proponents emphasise stability and neutrality; crypto advocates foreground decentralisation and technological efficiency [17] [3].
7. Bottom line for policymakers and citizens
Current reporting shows the dollar remains indispensable now while conversations about digital SDRs and crypto alternatives continue; any shift would require institutional decisions by the IMF and central banks and widespread legal, market and operational changes [5] [2] [3]. Available sources do not mention a credible pathway for private cryptocurrencies to supplant the dollar without those sovereign and multilateral steps [9] [10].
