Institutional OTC Trading in Switzerland: Desks, Settlement, and Prime Brokerage

Donovan Vanderbilt · 24 February 2026 · 9 min read

For institutional investors transacting in digital assets, the public exchange order book is rarely the right execution venue. A family office seeking to deploy CHF 5 million into Bitcoin, a corporate treasury unwinding a large ETH position, or an asset manager rebalancing a digital asset portfolio — all of these trades share a common problem: size. Executing an order large enough to matter on a public exchange order book will move the market against you, generating slippage that directly reduces the value of your transaction.

This is why OTC trading exists. And in Switzerland, the OTC market for institutional digital assets is more sophisticated, more regulated, and more institutionally mature than in virtually any other jurisdiction.

What is OTC Trading?

Over-the-counter (OTC) trading refers to transactions in financial instruments that take place outside a formal exchange. Rather than submitting an order to a public order book where it is matched against anonymous counterparties at market price, OTC trading involves direct, bilateral negotiation between two parties — the buyer and the seller (or more typically, the buyer and an OTC desk acting as principal).

In traditional financial markets, OTC markets have always accounted for the majority of institutional trading volume by value, even though exchange trading dominates by transaction count. Bond markets, foreign exchange, derivatives, and large equity block trades all rely heavily on OTC execution for the same reason digital asset OTC exists: institutional-sized positions require bespoke execution.

In digital asset markets, OTC desks emerged early in the industry’s development precisely because exchange liquidity, even on the largest venues, is insufficient for truly large block trades without causing significant market impact. The OTC market for digital assets has matured from informal phone-and-Telegram negotiation between Bitcoin early adopters into a structured, institutionally governed market with professional counterparties, legal documentation, and regulated settlement.

Why Institutions Use OTC Desks

The primary driver of institutional OTC usage is slippage avoidance. Slippage is the difference between the price at which you intend to execute a trade and the price at which you actually execute — caused by the fact that placing a large order into an exchange order book consumes available liquidity at the best price and forces the trade to walk up (or down) the order book to fill.

Consider a simplified example. If Bitcoin’s best offer on a major exchange is CHF 90,000 for 1 BTC, but the total liquidity available at CHF 90,000–90,500 is only 20 BTC, then an order to buy 50 BTC will consume all liquidity in that range and continue filling at progressively higher prices. The average execution price might be CHF 91,200 rather than the initial best offer of CHF 90,000 — a slippage of 1.3% that represents CHF 60,000 in direct execution cost on a CHF 4.5 million trade.

An OTC desk solves this by providing a single, firm price quote for the entire block. The desk aggregates liquidity from multiple sources — exchange order books, other OTC desks, market makers, its own inventory — and provides the institutional client with one price for the whole order. The client knows their exact execution cost before the trade settles.

Additional reasons institutions prefer OTC include:

Price certainty: A firm quote is binding. The client knows the execution price before committing to the trade.

Counterparty quality: Trading with a FINMA-licensed Swiss bank or securities dealer provides institutional-grade counterparty risk. The counterparty is supervised, audited, and subject to regulatory oversight.

Settlement certainty: Swiss OTC trades settle into regulated custody, with clear legal documentation of ownership and transfer.

Confidentiality: Large exchange orders are visible to market participants and can be front-run. OTC trades are private and do not signal to the market.

Relationship-based pricing: Regular institutional clients typically receive tighter spreads as the OTC desk relationship deepens.

Swiss OTC Providers

Switzerland’s FINMA-licensed digital asset institutions all operate OTC desks as a core institutional service.

Sygnum Bank OTC Desk

Sygnum Bank’s OTC desk is operated under its full banking and securities dealer licence, making it the most comprehensively regulated OTC counterparty in the Swiss digital asset market. Sygnum’s OTC desk serves institutional clients — asset managers, family offices, banks, and corporate treasuries — with bilateral execution of large digital asset transactions.

Sygnum’s banking licence means that OTC trades settling into Sygnum custody accounts benefit from the full Swiss banking regulatory framework, including segregated client assets and coverage under the Swiss depositor protection scheme (esisuisse) up to CHF 100,000. For larger institutional positions, the segregated custody structure under the DLT Act provides specific legal protections for digital asset holdings in the event of counterparty insolvency.

The Sygnum OTC desk also connects to the bank’s prime brokerage services, allowing institutional clients to utilise credit facilities and cross-asset netting in conjunction with OTC execution.

AMINA Bank OTC Desk

AMINA Bank (formerly SEBA Bank) operates a parallel institutional OTC desk with the same regulatory standing as Sygnum — banking and securities dealer licence, regulated custody settlement, and access to prime brokerage services. AMINA has developed particular strength in OTC execution for Middle Eastern and Asian institutional clients through its Abu Dhabi office, which supplements its Zug headquarters.

Bitcoin Suisse OTC

Bitcoin Suisse’s OTC desk is the oldest institutional digital asset OTC operation in Switzerland, having begun serving large client orders in the firm’s early years. Operating under its FINMA securities dealer licence, Bitcoin Suisse’s OTC desk provides quote-driven execution for retail and institutional block trades.

Bitcoin Suisse OTC is particularly relevant for Swiss private banking clients and family offices that have come to the firm through its White Label partnerships with retail banks — clients who prefer to consolidate their digital asset activity with a single regulated Swiss counterparty.

The RFQ Process: How an OTC Trade Works

Institutional OTC digital asset trading follows a standardised Request for Quote (RFQ) process that has become the market norm across Swiss OTC desks:

Step 1 — RFQ Submission: The institutional client contacts the OTC desk (typically via a dedicated relationship manager, a trading portal, or an API integration) and requests a quote for a specific trade. The RFQ specifies the asset (e.g., BTC), the direction (buy or sell), the quantity, the settlement currency (CHF, USD, EUR), and any timing constraints.

Step 2 — Price Discovery: The OTC desk aggregates liquidity from its sources — exchange books, internal inventory, other OTC desks — and calculates a firm, all-in price for the requested block. Aggregation typically takes seconds for standard sizes; very large or illiquid positions may require minutes.

Step 3 — Quote Delivery: The desk delivers a two-sided quote or a one-sided firm quote with a validity window — typically 30–60 seconds — during which the client can accept the price. The short validity window reflects the volatile nature of digital asset prices and the desk’s exposure during the aggregation period.

Step 4 — Acceptance and Commitment: The client accepts the quote within the validity window. At this point, the trade is committed. Both parties are bound by the quoted price regardless of subsequent market movement.

Step 5 — Settlement: Settlement occurs through pre-arranged custody accounts. For trades at Swiss FINMA-licensed desks, the digital asset leg settles into the client’s custody account at the OTC desk or is transferred to an externally specified wallet address. The fiat leg settles via wire transfer. Settlement timelines vary: same-day settlement is available for existing clients with pre-funded positions; T+1 is standard for fiat settlement.

Settlement: DLT Act Protections

One of the most significant institutional advantages of executing OTC trades with Swiss FINMA-licensed counterparties is the legal protection afforded to digital asset holdings under the Swiss DLT Act.

The DLT Act, which came into force in 2021, amended Swiss insolvency law to ensure that digital assets held in segregated custody accounts are protected in the event of the custodian’s insolvency. Unlike fiat currency held at a bank (which becomes a general creditor claim in insolvency), digital assets held in segregated DLT custody are treated as client assets that must be returned to the client — they do not form part of the bankrupt estate.

This is a fundamental institutional safeguard. It means that institutional clients trading OTC through Sygnum, AMINA, or Bitcoin Suisse and holding digital assets in custody with those firms have a legally enforceable claim to their assets even if the institution fails. The FTX collapse in 2022 — in which billions of dollars of client assets were commingled with exchange funds and became inaccessible in bankruptcy — demonstrated precisely why this protection matters.

Prime Brokerage in Switzerland

Sygnum and AMINA both offer prime brokerage services to institutional digital asset clients — a service model imported from traditional financial markets where prime brokers provide consolidated financing, execution, and custody services for institutional fund managers.

In the digital asset context, Swiss prime brokerage typically includes:

Unified margin accounts: The prime broker maintains a single account across which the client’s digital asset positions are managed, with netting of long and short positions reducing collateral requirements.

Cross-asset netting: Sygnum’s banking structure allows netting across digital and traditional asset positions in certain circumstances.

Securities lending: Prime brokerage clients can lend digital assets from their portfolio (earning lending fees) or borrow assets (to establish short positions or fund redemptions).

Execution aggregation: The prime broker routes execution across multiple venues — exchange spot, OTC desk, and DeFi liquidity sources in some cases — providing best execution documentation for regulatory compliance.

Reporting and custody: Consolidated reporting across all positions, with a single FINMA-supervised custodian for regulatory and audit purposes.

Copper.co: London Infrastructure, Swiss Connections

Copper.co, the London-based institutional digital asset infrastructure provider, warrants mention in the context of Swiss institutional OTC. While not a FINMA-licensed entity, Copper provides prime brokerage and custody infrastructure used by institutional traders accessing Swiss and European OTC markets. Copper’s ClearLoop technology — which allows institutional traders to maintain assets in Copper’s custody while trading across multiple exchanges and OTC desks without on-chain settlement for every trade — has become widely used by professional traders who want to minimise settlement latency and counterparty exposure.

Some Swiss institutional traders use Copper as their custody and prime brokerage layer while routing execution to Swiss OTC desks for FINMA-regulated counterparty quality on the trade itself.

2024: Record Swiss Institutional OTC Volumes

Swiss institutional OTC volumes reached record highs in the fourth quarter of 2024, driven by Bitcoin’s price rally to new all-time highs, strong institutional demand following the launch of US Bitcoin ETFs, and growing corporate treasury adoption of digital asset positions.

Sygnum reported record transaction volumes in Q4 2024. Bitcoin Suisse disclosed its highest quarterly OTC volumes since 2021. The volume recovery confirmed that Switzerland’s institutional OTC infrastructure — built through years of regulatory engagement and product development — had created durable client relationships and execution capacity capable of scaling with market growth.

For institutional investors assessing the Swiss digital asset OTC market, the combination of FINMA-licensed counterparties, DLT Act settlement protections, prime brokerage services, and a decade of operational track record makes Switzerland the most institutionally credible OTC jurisdiction in Europe.
