The Custody Bottleneck

A WIOSNA Briefing, May 2026

Why are emerging market banks stuck on stablecoin custody?

Top emerging market banks are stuck on stablecoin custody because the global custody providers they would normally rely on have little commercial reason to custody third-party stablecoins.

A senior banker in Karachi, Jakarta, Manila, Cairo, and Lagos is having the same conversation right now.

The remittance corridor architecture is built. The system integration is ready. The compliance team has signed off. The Sharia Supervisory Board has reviewed and approved the settlement structure. The internal stakeholders are aligned. The only thing missing is custody.

And so they wait. For JPMorgan to expand its custody offering beyond proprietary stablecoins. For Citi to greenlight third-party stablecoin custody for emerging market subsidiaries. For Standard Chartered to formalise the next phase of its digital asset architecture. For Deutsche Bank to confirm its corridor-bank custody framework.

This is not a coincidence. It is a structural bottleneck, and it will not resolve in the timeframe most emerging market banks are planning around.

Why won't global custodians hold third-party stablecoins?

The major global custody providers all face the same internal commercial logic. Each is investing in proprietary stablecoin issuance, JPMorgan's coin, Citi's tokenised deposits, HSBC's distribution pilots. Custodying third-party stablecoins (USDC, USDT, regulated EU and US stablecoins) sits in tension with monetising their own issuance economics.

The result is a posture that emerging market banks experience as patient institutional engagement but is structurally something else. It is a slow-rolled conversation in which the global provider builds capability primarily for its own network and primarily for the few large home-market clients who matter most to its commercial book. Pakistan, Indonesia, the Philippines, Vietnam, and Egypt are not the home markets these providers optimise for.

Even when one of the global providers does deliver custody capability, the offering is typically locked to their own coin. The bank that has waited eighteen months for the conversation to land finds itself architecturally tied to whichever issuer arrives first, with limited optionality on USDC, USDT, or any future regulated stablecoin issued under MiCA or the GENIUS Act.

The bank's settlement architecture, built carefully and approved through every internal layer, becomes commercially constrained by a single counterparty's product roadmap.

What is the alternative to stablecoin custody from top global banks?

Multi-stablecoin custody from CBUAE-licensed and Singapore MAS-licensed counterparties is operationally live today. So is custody under the Abu Dhabi Global Market FSRA framework, the Dubai Financial Services Authority framework, the Hong Kong Monetary Authority framework. These regulatory regimes have been operating institutional digital asset infrastructure for several years, and the firms licensed under them custody multiple stablecoins as a matter of regular business.

This is not a workaround. It is a different category of counterparty entirely. A CBUAE-licensed Virtual Asset Service Provider holding USDC, USDT, and EURC simultaneously, with full Travel Rule compliance, with established correspondent banking relationships, with audited reserve management, is operationally and regulatorily distinct from a top global bank slowly building a proprietary coin offering.

The institutional question is not "is this safe enough." The institutional question is "is this the right partner for the architecture we are actually building."

What should top emerging market banks do about stablecoin custody?

Top emerging market banks should set a firm deadline for the global custody path and move to licensed multi-stablecoin custody alternatives if it has not delivered by then.

The June 30 deadline that one top Pakistani bank has set for its global custody conversation is sharp institutional thinking, but it is also a pattern that should generalise. Emerging market banks should set a date by which they have given the global bank path every reasonable chance, and after which they engage seriously with regulated alternatives.

The framing is not "we are switching to crypto custody." The framing is "we are operating under the Markets in Crypto-Assets Regulation, the CBUAE Virtual Asset Service Provider framework, the Singapore Monetary Authority Digital Payment Token framework. These are the regulatory regimes that emerging market regulators are now adopting. We are not taking risk; we are taking the regulatory comfort that comes from operating inside frameworks more developed than our own."

That is institutional cover, defensible to compliance, defensible to the central bank, defensible to the board.

How long do emerging market banks have to decide on stablecoin custody?

Most emerging market banks have a two-quarter window to make this decision before competitive position becomes the constraint. The first top Pakistani bank to launch a corridor pilot will hold institutional advantage for two to three years. The first top Indonesian bank to launch a multi-corridor settlement architecture will become the regional clearing hub for ASEAN-Gulf flows. The first top Egyptian bank to operate cross-border stablecoin settlement at scale will set the template for North Africa.

These are first-mover positions, and they are unusually durable because the regulatory and Sharia framework conversations the first mover navigates become the precedent for everyone behind them.

The custody bottleneck is real. The waiting strategy is rational only until it is not. The window for institutional advantage is narrower than most banks are pricing in.
