What Happens to Stablecoins if the US Dollar Loses Reserve Currency Status?

The US dollar has been the world's dominant reserve currency for decades, comprising nearly 60% of global foreign exchange reserves. This status allows the US to run persistent trade deficits without facing major currency devaluation or inflation. However, some experts predict the dollar may lose this coveted position in the coming years. If that happens, it could have major implications for stablecoins like USDC that are pegged to the dollar.

Why the Dollar Could Lose Reserve Status

The dollar's reserve status is not guaranteed. History shows global reserve currencies change over time. The pound sterling held the top spot before World War II. Some factors that could catalyze a shift away from the dollar include:

The Rise of the Euro and Renminbi

The euro comprises around 20% of global foreign exchange reserves currently. Meanwhile, China is taking steps to internationalize the renminbi and increase its global usage. If these trends continue, they could challenge the dollar's dominance.

Loss of Faith in US Institutions

Ongoing dysfunction in Washington and rising US debt levels could undermine global confidence in the dollar over time. The US debt-to-GDP ratio now exceeds 100%, raising concerns about the country's ability to repay its debts.

The Growing Power of USD Alternatives

Initiatives like Russia and China's System for Transfer of Financial Messages (SPFS) aim to reduce dependence on the dollar for international payments. The rise of cryptocurrencies also gives nations and individuals alternatives to transact outside the dollar-based banking system.

What Would Happen to Stablecoins Pegged to the USD?

Stablecoins like USD Coin (USDC) could face major challenges if the dollar loses reserve currency status. Here are some potential scenarios:

The Dollar Could Depreciate Significantly

If global demand for the dollar declines, its value could fall sharply against other major currencies. This would reduce the backing value of USD-pegged stablecoins.

Stablecoins May Unpeg from the Dollar

Issuers might choose to break the peg between their stablecoins and the dollar to avoid devaluation. They could re-peg to a stronger currency like the euro or a basket of currencies.

Transfers Between Currencies Could Become More Expensive

Swapping between USD stablecoins and other currencies may incur higher fees and spreads as liquidity declines in dollar trading pairs.

Trust in All Fiat-Pegged Stablecoins Could Decline

Crypto users may view pegging to any single fiat currency as too risky if the dollar loses reserve status. This could spur greater adoption of algorithmic stablecoins like DAI.

Stablecoins Could Migrate to Bitcoin or Other Commodities

Some stablecoins may choose to abandon fiat currency pegs altogether in favor of pegging to decentralized assets like Bitcoin or commodities like gold.

How Would a Digital Dollar Impact Stablecoins?

If global demand for dollars declines, the US could issue a digital dollar to reclaim its reserve currency status. A blockchain-based e-dollar could have major impacts on private stablecoins:

A Digital Dollar Could Crowd Out Stablecoins

Central bank digital currencies (CBDCs) may reduce demand for private stablecoins if users view them as less risky than corporate-issued coins. However, stablecoins would retain advantages like programmability.

Stablecoins May Focus on Settlement While CBDCs Are Used as Money

Stablecoins could shift toward wholesale settlement between banks and institutions while CBDCs become the primary monetary medium for consumers.

Central Bank Partnerships Could Strengthen Stablecoins

CBDCs don't necessarily spell the end for stablecoins. We could see greater collaboration between national banks and stablecoin issuers like Circle and Tether to strengthen reserves.

Stablecoins May Focus on Domestic Use if CBDCs Dominate Global Trade

Nations issuing CBDCs may prefer using national digital currencies for international trade and reserves. This could lead stablecoins to focus on domestic payments rather than cross-border transfers.

Key Takeaways about Stablecoins in a Post-Dollar World

It's far from certain that the dollar will lose its reserve status anytime soon. But if it does, key shifts for stablecoins could include:

  • Breaking the peg from the dollar to avoid devaluation.
  • Facing higher currency conversion fees and spreads.
  • Greater competition from government-issued CBDCs.
  • Exploring new reserve assets like gold or crypto instead of fiat currencies.

Stablecoins still have advantages like programmability and composability that national digital currencies may lack. But the growth of CBDCs could force stablecoins to reconsider their designs and target markets in a post-dollar global economy. Companies and protocols that can pivot to new reserve assets and use cases are most likely to survive if the dollar declines as the world's primary reserve.


The potential decline of the US dollar as the dominant global reserve currency presents risks for USD-pegged stablecoins. But it could also open up opportunities for innovation in peg mechanisms and greater collaboration between private stablecoins and central bank digital currencies.

Ultimately, fiat-backed stablecoins must remain flexible and open to reinventing themselves in a changing monetary environment. Although stablecoins offer benefits like transparency, auditability and programmability, relying on a single fiat currency peg is risky in the long-term. By exploring decentralized reserve assets and adaptable exchange mechanisms, stablecoins can retain their usefulness even if the dollar loses its privileged status in the future global financial system.
