Crypto OTC desks, explained for institutions

Why OTC exists

Public crypto exchanges work well for ordinary sizes. But the moment an order is large relative to what’s resting on the order book, the exchange stops being the right venue. A block buy walks up the book — each tranche fills at a worse price than the last — so the average price you achieve drifts away from the screen price. That gap is slippage, and on a sizeable order it can dwarf any fee.

An over-the-counter (OTC) desk solves this. Instead of working an order across a public book, the institution trades directly with a single counterparty at one agreed price for the entire size. No slippage as you fill, no signalling your intent to the market, no broadcasting the trade to the public tape.

This is why funds, trading desks, treasuries and large corporates route block flow through OTC — and it’s the same logic FX desks have used for decades in currency markets.

What an OTC desk gives you

• Price certainty — one firm, executable quote for the full size. The price you agree is the price you get.
• No market impact — the order never touches a public book, so it can’t move the market against you or tip off other participants.
• Privacy — the trade is bilateral and off-tape.
• Size — block trades that would be impractical on-exchange are routine for a desk.
• Settlement handling — the desk manages the mechanics and the counterparty risk on both legs.

How execution actually works

Most institutional OTC trading runs on a request-for-quote (RFQ) model:

1. The client requests a quote for a specific pair and size — say, a seven-figure conversion of a stablecoin to sterling, or one major currency to another.
2. The desk returns a firm price, usually held for a short window so the client can confirm against the market.
3. The client accepts or passes. On acceptance the trade is done — bilaterally, immediately.
4. Settlement follows, typically same business day.

Alongside RFQ, desks provide voice and chat coverage — many institutional relationships still execute over a direct line or secure chat, especially for the largest or most time-sensitive tickets.

Liquidity and pricing

A desk’s quote reflects where it can source and offload the other side — across market makers, exchanges and its own inventory — plus a spread over the mid-market rate. The spread tightens with size and with the depth of the relationship: regular, larger counterparties price keener than one-off flow. The trade-off the client is paying for is certainty and zero market impact, which on block size is almost always worth more than shaving a basis point on a public book.

Settlement — and the stablecoin shift

Settlement is where modern crypto OTC has changed fastest. Trades settle bilaterally, usually T+0, and can move:

• fiat against crypto (the classic on/off-ramp block),
• crypto against crypto, or
• fiat against fiat (the FX leg).

Increasingly, the on-chain side settles in stablecoins — USDC, USDT or EURC — because they move dollar or euro value in minutes, around the clock, without waiting on banking hours. That makes the settlement leg of a block trade as fast as the execution. (See stablecoin settlement for how that leg works.)

Counterparty risk is the real discipline

Because OTC is bilateral, who you trade with matters as much as the price. A desk extends and manages credit and settlement risk on every ticket, which is why serious desks onboard counterparties through full KYB, sanctions screening and Travel Rule checks before a single trade — and trade only with regulated counterparties. The reputable end of the market competes on exactly this: tight pricing and clean settlement, not one at the expense of the other.

Where KwiikPay fits

KwiikPay runs a regulated OTC desk for institutional flow — block tickets above £250K, bilateral pricing, T+0 settlement and voice + chat coverage, with regulated counterparties only — as a registered VASP in Poland and, in Canada, a Payment Service Provider under the RPAA (Bank of Canada-supervised) and a FINTRAC MSB. What’s distinctive is the combination: the same desk handles crypto-fiat blocks and wholesale FX, and settles the on-chain leg in stablecoins where that’s fastest — so a fund or treasury moving size across both digital assets and currencies works with one regulated counterparty end to end, rather than stitching together a crypto desk, an FX broker and a settlement bank. If you’re running block flow, the desk is the place to start a conversation.
