IMF Warns Local Stablecoins Accelerate Dollarization via Onchain FX Bypass

Woofun AI reports that Dan Katz, the IMF's First Deputy Managing Director, raised a critical structural risk in August 2026: local-currency stablecoins could inadvertently accelerate the adoption of foreign-currency stablecoins. The core thesis posits that while domestic tokens may improve local payments, they simultaneously alter the ease with which users move between currencies, creating a vector for dollarization that policymakers must address before widespread deployment. This phenomenon is not merely about the issuance of a new asset but about the infrastructure through which currency conversion occurs, potentially undermining national monetary sovereignty in economies already vulnerable to external shocks.

The mechanism driving this risk lies in the ability of onchain conversion to bypass traditional financial infrastructure. Once a domestic stablecoin trades on the same infrastructure as USDT, USDC, and other dollar-pegged tokens, the conversion process that once depended on banks or traditional FX markets becomes possible directly onchain. Users may swap between local and foreign assets through exchanges, liquidity pools, or peer-to-peer transactions, shifting part of the currency conversion away from the infrastructure through which it traditionally took place.

This shift means that issuance is only one piece of the design; trading pairs, liquidity, and where conversions take place determine what the token ultimately becomes useful for, effectively decoupling currency exchange from regulated intermediaries.

A new domestic stablecoin would also be competing in a market that is already overwhelmingly dollar-based, facing significant structural headwinds from day one. The IMF states that close to 99% of stablecoins are denominated in US dollars, a figure corroborated by a 2026 BIS analysis which puts the share at roughly 98%. Dollar denomination is only part of that advantage; USDT and USDC already benefit from extensive exchange listings, wallet support, established trading pairs, and deep liquidity across crypto markets. Consequently, a local stablecoin can function exactly as intended and still offer users fewer places to spend, trade, or transfer it, making it difficult for a domestic alternative to compete with dollar tokens simply because it represents the local currency.

The effects of this concentration may extend beyond crypto trading into conventional foreign-exchange pricing. A 2026 IMF Working Paper examined four dollar-pegged stablecoins against 27 fiat currencies and found measurable links between stablecoin flows and conventional FX markets. The authors estimate that a 1% exogenous increase in stablecoin net inflows widened the difference between stablecoin and spot FX prices by around 40 basis points. Their results also showed depreciation pressure on local currencies and higher dollar funding premiums, indicating that demand for tokenized dollars can become large enough to affect conventional FX pricing and dollar funding conditions, even when the original transaction never passes through a traditional currency market.

For central banks and regulators, this creates a profound monitoring challenge in decentralized markets. Banks and licensed FX dealers give authorities identifiable places where transactions can be monitored, reported, or limited, serving as traditional checkpoints for capital flow management. Stablecoin conversions may involve different intermediaries, while decentralized and peer-to-peer markets can remove some of those traditional checkpoints entirely. This opacity makes it harder for economies that already restrict or manage access to foreign currency to enforce controls, as the infrastructure itself facilitates evasion of the very mechanisms designed to monitor and limit foreign-currency transactions.

Woofun AI data shows that a July BIS study covering more than 130 economies found that stablecoin activity and conventional dollarization tend to increase under similar conditions, including financial stress and exchange-rate pressure.

Notably, foreign-exchange and capital-flow restrictions appeared to have much less influence on stablecoin flows than on conventional foreign-currency deposits. The researchers suggest that activity outside the traditional regulatory perimeter may help explain the difference, highlighting a structural gap in current oversight frameworks. This persistence in dollarization behavior suggests that once households begin keeping part of their wealth in dollars, the behavior may continue even after the original period of economic stress has eased, creating long-term liabilities for national currencies.

The situation becomes more fragile in fixed exchange-rate regimes where the official exchange rate is misaligned with economic conditions. A 2026 IMF Working Paper examining these regimes found that stablecoins can provide another source of foreign currency and a more visible market price where dollar access is restricted. When the official exchange rate remains credible, that additional market can improve the allocation of scarce foreign currency.

However, if the official rate is badly misaligned, a visible stablecoin price can give households and businesses a common reference for what the local currency is worth outside the official market, potentially triggering coordinated exits from the domestic currency if confidence is already deteriorating.

The underlying economic context remains the primary driver of demand, with technology merely changing how that demand is expressed. A country with low inflation, credible monetary policy, and efficient domestic payments gives households fewer reasons to move into dollars. In an economy already dealing with depreciation, inflation, or shortages of foreign currency, demand for dollars may already exist before any local stablecoin appears. The technology does not create the underlying economic pressure; rather, it provides a more efficient channel for existing dollar demand to manifest, exacerbating the effects of inflation and loss of confidence in the domestic monetary system.

Measurement pitfalls further complicate the assessment of domestic stablecoin success, as raw metrics often obscure actual usage patterns. Authorities can count wallets, transaction volume, and circulating supply, but those numbers may tell very little about what users are actually doing with the asset. A local stablecoin could generate heavy transaction activity while serving mainly as an intermediate step between domestic money and dollar tokens like USDT or USDC. If the deepest market for the token develops against USDT or USDC, authorities would want to understand how much of that activity represents ordinary trading and how much reflects persistent conversion into dollars, especially when activity is distributed across decentralized exchanges and peer-to-peer markets rather than regulated venues.

This marks a critical juncture for policymakers evaluating the utility of domestic digital assets. Holding behavior could be even more informative than raw transaction counts; if users routinely receive the domestic token and quickly exchange it into dollar stablecoins, high adoption figures would tell a very different story from people using the token for salaries, savings, or everyday payments denominated in the local currency. Stable monetary policy and reliable domestic payments reduce the incentive to search for an alternative store of value, whereas easier digital conversion in weak economies may simply give existing dollar demand another channel. For governments considering local stablecoins, success may therefore require a broader measure than wallets or transaction volume, focusing instead on whether the token anchors economic activity in the local currency or accelerates its erosion.
