IMF Warns Stablecoins Could Cut Payment Costs but Raise Currency Risks

Stablecoins are moving into a new phase.

Once viewed mainly as a tool for cryptocurrency trading, dollar-backed digital tokens are increasingly being discussed as potential infrastructure for global payments. The technology could make some cross-border transactions faster and cheaper, but it could also create new challenges for countries trying to protect their currencies and maintain financial stability.

That tension was highlighted by International Monetary Fund Managing Director Kristalina Georgieva in remarks at the Jackson Hole Economic Policy Symposium on August 28, 2026.

Georgieva said tokenization and stablecoins could help make global finance more fluid, with stablecoins showing potential to make large-value cross-border payments cheaper and faster. At the same time, she warned that a more fluid financial system can transmit risks more quickly and create a greater penalty for policy mistakes.

Why Stablecoins Could Make International Payments Cheaper

Cross-border payments remain one of the more complicated parts of the global financial system.

A payment moving between countries can pass through banks, correspondent institutions, payment networks, foreign-exchange providers and other intermediaries. Each additional layer can add costs, processing time or operational complexity.

Stablecoins offer a different model.

A blockchain-based stablecoin can potentially move value across borders at any time without relying on every traditional payment layer to process the transaction in the same way.

That does not mean every stablecoin payment will automatically be cheaper. Users can still encounter blockchain fees, exchange-rate spreads, conversion costs, custody fees and other charges.

But the underlying technology could reduce friction in some high-value international transactions.

What Georgieva Actually Said

The IMF's position is more nuanced than simply being for or against stablecoins.

In her August 28 speech, Georgieva said financial innovation has historically improved domestic payments in terms of speed, convenience and cost. She also noted that progress in cross-border payments has been uneven, with many transactions remaining expensive and slow.

She identified stablecoins and tokenization as technologies that could potentially contribute to a broader transformation of cross-border payments.

But Georgieva also emphasized that the benefits come with risks that policymakers need to address.

The IMF's concern is therefore not that stablecoins are guaranteed to destabilize emerging markets. Rather, the concern is that widespread adoption—particularly of foreign-currency stablecoins—could create additional pressure on countries with weaker currencies or less resilient financial systems.

The Currency-Substitution Problem

One of the biggest issues is currency substitution.

Imagine a country where inflation is high and people are losing confidence in the domestic currency.

Residents may already prefer to hold U.S. dollars as a store of value. A dollar-backed stablecoin could make that foreign-currency exposure easier to obtain, transfer and use digitally.

If enough people begin using the stablecoin for savings, payments or pricing, the domestic currency could gradually lose some of its traditional role.

That is where the issue becomes important for central banks.

Monetary policy works partly through demand for the domestic currency and the domestic financial system. If economic activity increasingly shifts toward a foreign-currency stablecoin, the transmission of monetary policy could become more difficult.

Why Emerging Markets Could Face Greater Pressure

Not every country would experience the same effects.

Countries with strong currencies, deep financial markets and credible institutions may be better positioned to absorb the changes.

Emerging markets and developing economies with weaker currencies, higher inflation or tighter capital controls could face greater pressure if foreign-currency stablecoins become widely adopted.

According to Georgieva, stablecoins could potentially make capital controls more porous and contribute to several related risks, including:

• Currency substitution
• Capital-flow volatility
• Exchange-rate instability
• Reduced monetary-policy effectiveness
• Pressure on monetary sovereignty

Faster Payments Can Also Mean Faster Risk

This is one of the less obvious parts of the stablecoin debate.

The same infrastructure that makes payments move faster during normal conditions can also allow capital to move more quickly during periods of financial stress.

If investors can rapidly convert local assets into a dollar-backed digital token and transfer those tokens abroad, capital outflows could potentially happen faster than they would through traditional channels.

That does not mean every stablecoin transaction represents capital flight. Most transactions may have perfectly legitimate commercial purposes.

The concern is what could happen when large numbers of users react simultaneously to an economic shock.

Stablecoins: Potential Benefits vs. Potential Risks

Potential Benefit	Potential Risk
Faster cross-border settlement	Faster movement of capital during financial stress
Potentially lower payment costs	Greater foreign-currency competition
More competition among payment providers	Pressure on traditional bank deposits and funding
Greater access to digital payments	Currency-substitution risks
Programmable digital payments	New regulatory and financial-stability challenges
Potentially broader global financial access	Greater exchange-rate and capital-flow volatility

The Banking System Could Also Feel the Impact

Stablecoins are not only a monetary-policy issue.

They could also affect commercial banks.

If consumers and businesses move significant amounts of money from traditional bank deposits into stablecoins, banks could potentially lose part of their deposit funding base.

That matters because bank deposits are an important source of funding for lending to households and businesses.

Georgieva therefore highlighted the importance of preventing excessive bank disintermediation while allowing competition and innovation to develop.

In other words, regulators need to make sure stablecoins improve financial competition without unintentionally weakening the banking system that supports the wider economy.

Why Reserve Management Matters

There is another issue that often gets overlooked when discussing stablecoins: the assets backing them.

A stablecoin is only as credible as the mechanism that allows users to trust its value and redemption process.

For a dollar-backed stablecoin, users need confidence that the issuer maintains appropriate reserves and that those reserves can support redemption at or close to the promised value.

That is why Georgieva called for strong rules around reserve pools and international coordination.

Without transparency, liquidity and reliable redemption mechanisms, the promise of a stable digital dollar can quickly become a source of financial risk.

Could Stablecoins Strengthen the Dollar?

Most of the world's largest stablecoins are linked to the U.S. dollar.

That means stablecoin growth could potentially increase the global reach of dollar-denominated assets.

Someone who does not have easy access to traditional U.S. banking services may nevertheless be able to obtain a dollar-backed digital token through a crypto platform or other service.

For users, that can provide another way to hold and transfer dollar-denominated value.

For policymakers in other countries, however, the same development raises questions about the long-term role of their domestic currencies.

This is why stablecoins are increasingly being discussed as part of the international monetary system rather than simply as another cryptocurrency product.

Regulation Will Be Critical

The IMF's message points toward a regulatory challenge that will likely become more important as adoption grows.

Governments need to allow useful innovation without creating loopholes that encourage regulatory arbitrage.

Some of the questions regulators will need to address include:

• How should stablecoin reserves be regulated?
• What standards should issuers follow?
• How should users be protected?
• How should cross-border transactions be monitored?
• What happens if a major stablecoin experiences a loss of confidence?
• How should stablecoin intermediaries interact with banks?
• How should governments respond to widespread foreign-currency stablecoin adoption?

These are not questions that can be answered by technology alone.

They involve monetary policy, banking regulation, taxation, consumer protection and international cooperation.

Stablecoins Are Not Automatically Good or Bad

The stablecoin debate is sometimes presented as a simple choice.

Either stablecoins are the future of payments, or they are a threat to traditional finance.

The reality is more complicated.

They can potentially solve genuine problems in cross-border payments while simultaneously creating new risks.

A payment system that is faster and cheaper can be extremely useful. But if the same system allows capital to move across borders almost instantly during a crisis, policymakers need safeguards capable of dealing with that speed.

That is the balance the IMF is highlighting.

What This Means for Crypto and Traditional Finance

For the cryptocurrency industry, Georgieva's remarks are another indication that stablecoins are being taken seriously as financial infrastructure.

For banks, the message is equally important: digital payment technology could increase competition and force traditional institutions to modernize.

For emerging markets, however, the stakes may be higher.

The adoption of foreign-currency stablecoins could provide consumers with cheaper and more convenient ways to move money, but it could also challenge domestic currencies if adoption becomes widespread.

That means the next phase of stablecoin development will likely be shaped as much by regulation and monetary policy as by blockchain technology.

The Bottom Line

Stablecoins could make parts of the global payment system faster, cheaper and more competitive.

That is the opportunity.

The risk is that greater financial fluidity also means greater speed when money moves out of a country, a bank or a domestic currency.

IMF Managing Director Kristalina Georgieva's message is therefore not that stablecoins should be stopped. It is that the benefits of financial innovation need to be accompanied by strong regulation and sound macroeconomic policy.

For emerging markets, the central question may ultimately be whether they can embrace the efficiency of digital dollars without allowing those digital dollars to weaken confidence in their own currencies.

Stablecoins may be part of the future of global payments. How that future affects monetary sovereignty, banks and exchange rates will depend heavily on the rules built around them.
