USD access in emerging markets fails through sanctions, de risking, and FX crises.
Reader Brief
Every emerging market operates under an implicit assumption: US dollars will be available through correspondent banks when needed. That assumption has failed, repeatedly. The question isn't whether alternative rails exist - it's whether the jurisdiction built them before the failure.
What's Inside
The three patterns of USD stoppage, the stablecoin access property, and the political reason many exposed jurisdictions wait too long.
This Perspective follows a simple path: first the implicit USD-access assumption, then the three stoppage patterns, then the stablecoin dimension, the jurisdictional preparation question, the political resistance pattern, and the strongest counter-arguments.
Three patterns of USD stoppage with distinct triggers and durations: sanctions, de-risking, and FX crisis.
Each pattern has a different trigger and a different duration. Sanctions are political and last decades. De-risking is commercial and is typically permanent. FX crisis is domestic and resolves in months to years. The response that works for one does not work for the others.
22% decline in global correspondent banking relationships from 2011 to 2019, with USD access concentrated in a handful of US correspondents.
The structural fragility is concentration. A handful of US banks intermediate global USD access. When any one of them re-prices or exits, dependent emerging-market banks lose USD clearing capacity and rarely regain it. BIS CPMI data shows declining relationships do not recover [1].
Marginal access property: stablecoin operators do not require bilateral correspondent relationships.
A correspondent bank needs a specific US counterparty. A stablecoin operator can hold USDC or USDT through any available channel: exchange, OTC, peer operator, or liquidity provider. Channel diversity means individual failures do not eliminate access. This is the single mechanism that explains why crisis-era stablecoin demand spikes in Argentina, Venezuela, Lebanon, and Turkey [4].
Build before failure: Nigeria pre-2023 ban versus UAE, Singapore, and Kenya pre-licensing.
Nigeria banned stablecoins, faced FX crisis without licensed alternatives, watched informal markets fill the gap with no regulatory visibility, then reversed in 2023. UAE, Singapore, and Kenya licensed operators in advance. When correspondent or FX pressure emerged, the alternative rail was already operational. The strategic framing is not "adopt or ban" but "build before you need it."
The Underlying Assumption
Emerging-market USD liquidity depends on regulated correspondent banking access.
Emerging market economies import USD liquidity through correspondent banking relationships. Local banks clear USD flows through a small number of US-based correspondents: BNY Mellon, Citi, JP Morgan, and a few others. The dependency is structural: without correspondent access, USD does not flow into the jurisdiction through regulated channels. This dependency has failed multiple times. Each failure is treated as exceptional. The pattern is structural.
- 22% Decline in global correspondent banking relationships, 2011-2019. BIS CPMI correspondent banking data anchors the structural decline [1].
- 5-7 US correspondents processing the majority of global USD flows to EM banks. A concentration point that exposes the fragility of regulated USD access.
When Dollars Stop: The Patterns
Sanctions, de-risking, and FX crisis stop USD access for different reasons and on different timelines.
USD access has failed in emerging-market jurisdictions through three distinct patterns. Each has specific triggers and specific durations. Understanding which pattern is operative determines what response is viable. The taxonomy is simple: sanctions are political and long-lived; de-risking is commercial and often permanent; FX crisis is domestic and usually measured in months to years.
Pattern 1: Sanctions. Iran, Russia, Venezuela, Cuba, North Korea.
Sanctions are the cleanest form of USD stoppage. US Treasury designates specific entities or jurisdictions; US correspondents cannot process flows without explicit authorization; non-US correspondents face secondary sanctions risk if they maintain the relationship. Duration: multi-year to multi-decade. Cuba has been sanctioned since 1960; Iran since 1979; Russia expanded sanctions since 2022. Removal is a political process with long timelines. Affected economies adapt over time through alternative currency settlement, informal networks, and state-to-state settlement mechanisms. The stablecoin dimension: USDT and USDC are US-adjacent instruments. Sanctions enforcement against them is possible though varies by operator. The broader crypto infrastructure is more resistant to targeted sanctions because it operates without central intermediaries. Monetary Sovereignty in the Age of Stablecoins covers the sovereignty implications.
Pattern 2: De-risking. Most of the Caribbean, Central America, Pacific islands, and Francophone Africa.
De-risking is the quiet pattern. No political decision; no formal announcement. US correspondents review their emerging-market relationships on a risk/revenue basis and exit ones where compliance cost exceeds revenue. Triggered by AML/CFT enforcement actions raising compliance cost, Basel capital charge increases on trade finance, volume too low to justify a dedicated compliance team, or specific emerging-market entity AML incidents raising correspondent reputation risk. Duration: typically permanent. Correspondents do not typically re-enter exited jurisdictions. BIS CPMI data shows the declining relationships do not recover [1]. Affected economies respond through regional correspondents, fintech aggregators, and increasing stablecoin adoption where regulation permits. The stablecoin dimension: for consumer and SME flows, licensed stablecoin operators now provide the path that de-risked banks no longer can. For large institutional flows, the gap persists. The CBR Exodus documents de-risking at scale.
Pattern 3: FX crisis. Argentina, Turkey, Nigeria, Egypt, Sri Lanka, Lebanon.
FX crisis is the domestic pattern. Correspondents are available in principle, but the central bank lacks FX reserves to satisfy demand. Banks ration USD access; official exchange rates diverge from parallel market rates; importers and remitters face explicit caps. Triggered by a current account deficit financed by short-term debt, sudden capital flight, external debt rollover failure, or a sovereign credit event or near-event. Duration: months to years. Usually resolves with an IMF program, currency depreciation, or capital controls. Some economies cycle through crises repeatedly, including Argentina. Affected economies respond through dual exchange rates, informal USD circulation, and stablecoin adoption as alternative USD access. The stablecoin dimension: this is where stablecoin demand spikes dramatically. In Argentina, Venezuela, Lebanon, and Turkey, stablecoin adoption jumps during crises because official USD access is unavailable while parallel USD is expensive or risky [4].
What The Stablecoin Dimension Adds
Stablecoin rails add USD-denominated access without depending on one correspondent relationship.
In all three patterns, stablecoin infrastructure provides something correspondent banking cannot: access to USD-denominated value without dependence on a specific correspondent relationship. This is not about whether stablecoins are "better." It is about what they enable that the alternative does not.
The marginal access property: USD exposure without USD correspondent dependency.
A correspondent banking relationship is bilateral: the emerging-market bank needs a specific US counterparty to hold nostro balances and clear USD flows. If that counterparty exits, the emerging-market bank loses access until another counterparty is found, often never. A stablecoin operator does not need a specific correspondent relationship. It holds USDC or USDT liquidity through any available channel: exchange, OTC, liquidity provider, or peer operator. The diversity of access means individual channel failures do not eliminate access. This is marginal access: the operator can provide USD-denominated settlement even when traditional channels fail. Not all correspondent banking problems convert to stablecoin opportunities, but the marginal access property means stablecoin rails become differentially valuable when traditional channels fail.
The Strategic Implication
The core policy question is what infrastructure exists before the USD-access failure arrives.
For any emerging-market jurisdiction, the strategic question is not whether USD access will fail. It is when and how, and what infrastructure exists to absorb the failure when it happens. Jurisdictions that build alternative rails in advance of failure have different outcomes than jurisdictions that wait.
| Preparation status | Failure outcome |
|---|---|
| Licensed operators plus infrastructure in place | Gradual substitution; volume shifts to alternative rails; economy absorbs the shock |
| No licensed alternative, but informal exists | Informal markets expand; price discovery moves to parallel channels; regulatory visibility declines |
| Neither licensed nor informal alternatives | Economic contraction; USD-denominated trade and remittance stop; economic growth suffers |
The implication is not "ban stablecoins" or "adopt stablecoins." It is "build the alternative before you need it."
Some jurisdictions, including Nigeria pre-2023, banned stablecoins and then faced crisis-era USD access problems without alternatives. Informal markets filled the gap, but regulatory visibility disappeared. Nigeria subsequently reversed course in 2023 and began licensing operators. Other jurisdictions, including UAE, Singapore, and Kenya, licensed stablecoin operators in advance of any crisis. When correspondent pressures emerge or FX stress appears, the alternative rail is already operational. The strategic framing: stablecoin infrastructure is a form of payment system resilience. Jurisdictions that treat it as a threat are treating their own resilience as a threat. Jurisdictions that treat it as infrastructure build the resilience into the system. The Two-Stage Framework describes the regulatory design that enables this.
The Uncomfortable Political Truth
The jurisdictions most exposed to USD stoppage are often the most resistant to alternative rails.
The political reality of "when dollars stop" is that the jurisdictions most exposed are often the ones most resistant to building alternatives. The same political conditions that create correspondent or FX pressure also create political resistance to stablecoin adoption.
The resistance pattern: fear of capital flight, fear of dollarization, fear of loss of monetary control.
Jurisdictions facing FX pressure often react to stablecoin adoption with restrictions, fearing that stablecoins will accelerate dollarization and reduce monetary policy traction further. This is understandable but counterproductive. The evidence: restricting stablecoin access does not prevent dollarization. It drives it informal. Informal dollarization is both more dollarized, because it is harder to partially regulate, and less visible, so regulators lose tools to manage it. The pragmatic response: build the two-stage framework that separates transit, enabled and regulated, from holding, regulated and contained. This preserves monetary control while enabling payment infrastructure resilience. Jurisdictions that have adopted this design, including Brazil, UAE, Singapore, and the UK proposal, maintain both.
Counter-Arguments and Limitations
Every perspective has boundaries.
The strongest challenges to this analysis are not technical. They are monetary-policy and political-economy objections: the rail can accelerate dollarization, and the jurisdictions that need pre-positioned infrastructure may be the least able to authorize it before crisis.
"Stablecoin adoption during USD failures accelerates dollarization rather than absorbing it."
The argument: once stablecoin rails are operational, savings flow into USD-denominated digital assets at the first sign of FX stress. The infrastructure built "for resilience" becomes the channel that empties domestic deposit bases. The jurisdictions that licensed stablecoin operators are choosing speed of dollarization over depth of monetary control, and the choice is not reversible once the rail is built. Valid concern, addressed by the two-stage framework. Without separation between transit and holding, this critique is correct. With separation - transit enabled, holding contained - the rail moves payments without unlimited domestic savings substitution. Brazil's framework demonstrates the design: residents can transact with stablecoins for cross-border payments but cannot park savings in them via licensed operators. The piece does not argue for unlimited stablecoin holding; it argues for licensed transit infrastructure with calibrated holding constraints. Jurisdictions that license without two-stage design face the dollarization acceleration the critique describes.
"Pre-positioning licensed operators is impossible because political constraints prevent it in the jurisdictions most exposed."
The argument: the jurisdictions most exposed to USD failure are also the ones whose political economy makes pre-licensing impossible. Currency-defending central banks resist any tool that accelerates dollar substitution. By the time political conditions allow licensing, the crisis has already happened and the informal market has captured the volume. Nigeria pre-2023 is not an exception - it is the rule. Partially valid. The piece does not claim every jurisdiction will pre-position. It claims jurisdictions that do pre-position have measurably different crisis outcomes than those that do not. The political constraint is real but not absolute: Brazil, UAE, Singapore, and Kenya all licensed under varying levels of political resistance. The piece's strategic framing is targeted at jurisdictions where the political conversation is still open: most of Africa, Southeast Asia, and Latin America outside the major dollarized economies. For jurisdictions where the conversation has already closed, including sanctioned economies and hardline restrictionists, the framing has limited applicability.
