Bequant — Institutional Trading Infrastructure & Prime Services

Tight spreads on OTC trades are table stakes. In 2026, the desks that win institutional flow are the ones with fiat rails that actually settle — fast, reliably, and in the currencies clients need.

The conversation has shifted

A few years ago, picking an OTC desk was mostly a spread conversation. You called three or four counterparties, got quotes on a $10M BTC block, and took the tightest price. Execution was the product. Settlement was an operational detail someone in the back office would handle on Monday.

That world is gone. Spreads across the serious institutional desks have compressed to the point where the differences are measured in single-digit basis points on major pairs. Everyone can quote tight. What separates a working OTC relationship from a broken one in 2026 is whether the settlement rails on the other side of the trade actually do what they're supposed to do — get fiat to the right account, in the right currency, within the window the client actually needs.

"Best execution" used to mean best price. Increasingly, it means best price that settles. A 5bp improvement on a quote is irrelevant if the EUR leg takes four days to clear because your desk's banking partner flagged the transaction for review. Institutional desks running cash management, treasury, or market making operations simply cannot afford that. So the question clients are asking has changed. It's no longer "what's your spread" first. It's "where can you settle, how fast, and how reliably."

The state of the fiat stack in 2026

Three currencies, three very different stories.

EUR is working. Post-MiCA, the EU has ended up with a mature institutional rail for euro settlement into and out of crypto. SEPA Instant is now the default for smaller flows, correspondent banking works for larger ones, and regulated CASPs with established banking relationships can settle same-day for most institutional clients. The MFSA, BaFin, and other EU regulators have given banks enough clarity that serving authorised CASPs is now a normal business line rather than a risk decision that gets escalated every quarter. Same-day or next-day EUR settlement on large tickets is achievable with the right counterparty — not always, but routinely.

USD remains the hard one. The US banking system is, for structural reasons, still the most difficult major currency to accommodate for non-US crypto desks. Correspondent banking access has not fully recovered from the post-SVB/Signature/Silvergate period, even as US regulatory clarity has improved. Desks routing USD through international correspondents deal with timing windows, compliance scrutiny, and settlement delays that are simply more severe than EUR equivalents. It's workable, but it's not smooth — and any OTC counterparty claiming "frictionless USD settlement" without a real US banking footprint is overselling. The honest answer is that USD works, but it's slower and more operationally intensive than EUR, and clients should plan accordingly.

AED is where the most change is happening. The UAE has moved from crypto-permissive to actively crypto-integrated over the past 18 months. Zand Bank is operating as a digital asset custodian and AED stablecoin issuer. MBank backs AEcoin and has extended into USDU. RAK Bank and Ruya have crypto-business desks. The CBUAE licensed AE Coin in January 2025, and dirham-backed stablecoins are now the officially sanctioned rail for domestic payment-token use. Bybit launched AED trading pairs in March 2026. For institutional clients with UAE operations — hedge funds with Abu Dhabi bases, token projects treasurying in the region, family offices running MENA allocations — AED rails that were effectively absent two years ago are now a real, routable option. The bottleneck has moved from "can we settle in AED at all" to "which counterparty has the relationships to do it at institutional size."

The banks now serving CASPs under MiCA

The quiet structural shift behind all of this is that institutional-grade banking for crypto businesses has finally started to exist in Europe. Three years ago, a regulated CASP looking for a serious EUR banking partner had a short, awkward list. In 2026, the list is real — and growing.

The MiCA framework is what changed the calculation for banks. Before authorisation existed, serving crypto clients was a compliance judgement call that most risk committees wouldn't approve. With MiCA-authorised CASPs, the counterparty's supervisory status is visible, their AML obligations are defined, and the bank's own regulator has a clear view of what they're banking. The risk conversation shifted from "is this client exposure too hard to explain" to "this client is authorised under the same framework we're already supervised by." Several categories of bank have stepped into the space that opened up:

Dedicated crypto-native banks and payment institutions. BCB Group is the clearest example — FCA-regulated in the UK, AMF/ACPR-regulated in France, with payment and e-money accounts in 20+ fiat and digital currencies, SEPA and SWIFT connectivity, and a proprietary instant-settlement network (BLINC) that clears 24/7 between counterparties inside the ecosystem. Over 250 institutional clients now route fiat through BCB, including exchanges, market makers, funds, and custodians. Built for crypto from day one, without the legacy-systems drag.

Swiss regulated crypto banks expanding into the EU. AMINA Bank AG (formerly SEBA) is a FINMA-licensed Swiss bank that secured a CASP licence under MiCA via its Austrian subsidiary in October 2025, giving it passporting access to 30+ European markets. Sygnum, its Swiss peer, has taken a similar path with off-exchange custody and institutional banking services. Both bring actual bank-grade balance sheets to the table rather than fintech infrastructure.

Mainstream EU banks entering crypto under MiCA. This is the genuinely new category. Deutsche Bank, Commerzbank, DZ Bank, and LBBW have all moved into regulated crypto services in Germany. Société Générale-Forge in France has issued a MiCA-compliant EUR stablecoin. Germany alone added 16 MiCA-licensed institutions in Q4 2025. Most are starting with custody or execution and expanding from there — but the fact that tier-1 European banks are now willing to have "crypto-asset service provider" on their licence is a material change in the landscape.

For a CASP running an OTC desk, the practical impact is that banking diversification is finally achievable. Two years ago, losing your one crypto-friendly banking relationship was an existential threat. Now, a serious institutional counterparty can layer BCB for instant intra-network settlement, a dedicated crypto bank like AMINA for balance-sheet services, and relationships with MiCA-compliant mainstream banks for correspondent reach. That redundancy is what lets you make settlement commitments to clients and actually keep them when one leg of the stack has a bad day.

It's also worth saying what hasn't changed: serving a CASP still requires the bank to want to do it. MiCA authorisation has dramatically lowered the friction, but banks still assess each CASP individually on governance, AML framework, and operational quality. A MiCA licence gets you to the conversation. The strength of your compliance operation is what gets you the account.

Why this matters for OTC specifically

OTC trades are typically large, time-sensitive, and routed around the open market precisely because moving that size on-exchange would cost the client materially more in slippage. The whole point is that the block trades at an agreed price and settles cleanly. The moment settlement becomes uncertain, the value of the OTC channel collapses — the client may as well have worked the order on-venue.

Three specific pain points separate a working OTC relationship from a broken one:

Pre-settlement risk window. The time between trade agreement and final fiat settlement is the period during which the client carries counterparty risk. The shorter that window, the lower the risk. Desks that can settle fiat same-day on EUR and next-day on AED are offering a materially different product from desks that quote tight but settle T+3.

Currency pairing without intermediate hops. If a client wants to move USDT to EUR, the question is whether that happens as a direct conversion or whether they first go USDT → USD → EUR, picking up FX spread and two sets of banking friction along the way. Desks with direct fiat pairs in the client's home currency remove a layer of cost and risk. In 2026 that increasingly includes AED alongside the majors.

Predictability under load. Fiat rails behave differently during volatility spikes, end-of-quarter periods, and holiday windows. A desk with robust banking relationships and multiple correspondent options settles consistently. A desk with a single thin banking relationship is fine until it isn't — and usually the moment it isn't is the moment the client most needs settlement to work.

What a serious OTC desk looks like now

The architecture worth looking for, in rough order of importance:

Real banking relationships in multiple currencies. Not a single account at a single correspondent, but relationships deep enough across EUR, USD, AED, and the smaller majors to route around problems when they occur.

Regulated entity status. Banks will serve regulated CASPs in 2026 that they wouldn't serve three years ago. Authorised status under MiCA, MFSA, FSRA, or comparable frameworks is now a precondition for meaningful banking access — not a nice-to-have.

Settlement transparency. Clients need to know, at point of trade, exactly when their fiat or crypto will land. "Usually same-day" isn't a commitment. "Settled within X hours via Y rail" is.

Integration with the wider execution stack. OTC trades rarely sit in isolation. They feed into hedge positions, inventory management, market-making books, and treasury flows. A desk that runs its OTC book on the same infrastructure as its execution and risk systems has a structural advantage — one unified view of exposure, collateral, and settlement obligations.

Judgement on sizing and timing. Serious OTC desks don't just quote — they know when to quote, when to hold off, and when to suggest splitting a block across a window. That judgement comes from running the book through real market cycles, not from an algo.

How Bequant structures this

Bequant operates its OTC desk from Malta (Bequant Pro, MFSA-regulated CASP, MiCA authorisation in process) and Seychelles (Bequant Prime), with banking relationships built specifically around where institutional clients actually need to settle:

EUR settlement via the European rail. Same-day or next-day EUR settlement on institutional tickets is the norm, not the exception, for clients running through Bequant Pro. MFSA regulation gives our EU banking partners the comfort level required to treat crypto flows as regular institutional business.

USD with eyes open. We don't overclaim on USD. Settlement works, but we're honest with clients about the timing windows and the additional compliance steps involved. For dollar-heavy flows, we'll tell clients upfront what the realistic settlement path looks like rather than quote a tight spread we can't support operationally.

AED as a first-class currency. The UAE rail has matured fast, and Bequant has built the relationships to settle in AED at institutional size. For MENA-based funds, family offices, and token projects, this means direct AED/crypto pairings without routing through USD — which removes both FX cost and an extra layer of settlement risk.

Integrated into the wider prime services stack. OTC flow feeds into the same DMA infrastructure and RiskQuant engine that power Bequant's market making, lending, and execution services. Clients running OTC blocks alongside portfolio-margined lending or cross-venue execution get a unified view — and one counterparty relationship — across all of it.

Settlement-first quoting. When we quote a block, we commit to settlement timing alongside price. A tight spread with uncertain settlement isn't a competitive quote in 2026. Clients know what they're getting, when they're getting it, and in which currency — at point of trade.

For institutional desks choosing an OTC counterparty, the 2026 question isn't which desk gives the best price on a screenshot. It's which desk actually settles the trade when the pressure is on. That's a harder thing to market — but it's the only thing that matters.
