Plain English definitions of every term you’ll encounter in cross-border payments, FX, and digital assets — from SWIFT and SEPA to stablecoins and VASPs. Written for finance and treasury teams, not developers. Terms are listed alphabetically.
The US domestic payment network used for bank-to-bank transfers including payroll, direct debits, and business-to-business payments. ACH typically settles same or next day.
Regulations requiring financial institutions to monitor, detect, and report suspicious transactions to prevent proceeds of crime entering the financial system. Applies equally to fiat payments and digital asset transfers.
A formal confirmation by an independent auditor that a stablecoin issuer holds the reserves it claims. Circle publishes monthly Big Four attestations for USDC.
A service that puts idle safeguarded balances to work, generating variable returns without sacrificing liquidity. Clearing’s balance optimisation service links returns to EFFR (the US Federal Funds Rate) with full liquidity and no minimum balance.

Clearing House Automated Payment System. The UK’s same-day high-value payment rail, used for large domestic GBP transfers. Settles in real time during banking hours.
The system by which banks make international payments through chains of intermediary banks, each holding accounts for the next in the chain. Each hop adds time, cost, and opacity to the transfer.
Any payment where the payer and recipient are in different countries. Cross-border payments typically involve currency conversion, correspondent bank routing, and compliance checks — all of which add cost and delay.

Financial Transactions and Reports Analysis Centre of Canada — the regulator overseeing money services businesses and VASPs in Canada. Clearing Payments Ltd. is registered with FINTRAC as an MSB and VASP.
The conversion of one currency into another. FX is a core component of cross-border payments. Rates fluctuate continuously based on market conditions, and providers vary widely in the spread they add above the mid-market rate.
The difference between the mid-market exchange rate and the rate a provider charges. Hidden FX spreads are one of the main cost components in traditional cross-border payments — often unmarked and difficult to compare.
The official currency of the United Kingdom. GBP payments domestically use Faster Payments or CHAPS. International GBP transfers typically route through SWIFT.

Know Your Customer / Know Your Business — the identity verification and due diligence checks financial institutions must complete before onboarding clients. Required by regulators across all jurisdictions as part of AML compliance.

The process of converting a stablecoin or digital asset back into fiat currency at the point of receipt. Clearing Payments Ltd. provides regulated off-ramp services in Canada.
Activity recorded directly on a blockchain ledger, as opposed to off-chain activity processed by intermediaries. On-chain transactions are publicly verifiable and irreversible once confirmed.
The process of converting fiat currency into a stablecoin or digital asset at the point of payment. Together with off-ramp, this enables businesses to use blockchain settlement rails without requiring recipients to hold digital assets.
The underlying infrastructure over which a payment travels. Traditional rails include SWIFT, SEPA, CHAPS, and Faster Payments. Blockchain networks are an emerging alternative rail for cross-border settlement.
Capital held in advance in foreign currency accounts (nostro accounts) to enable international payments. A significant working capital cost for banks and payment providers operating across multiple currencies.

The Society for Worldwide Interbank Financial Telecommunication. The messaging network used by banks to instruct international payments. Most international wire transfers rely on SWIFT, adding correspondent bank hops and 1–5 day settlement delays.
Settlement timelines in traditional finance — a transaction settles one, two, or three business days after the instruction date. T+2 and T+3 are standard for international correspondent payments and many securities transactions.
A FATF requirement that VASPs collect and share originator and beneficiary information for digital asset transfers above a threshold — the equivalent of SWIFT messaging data applied to blockchain transactions.
The function responsible for managing a company’s liquidity, currency exposure, cash flow, and financial risk. For internationally active businesses, treasury management increasingly involves decisions about payment rails, FX strategy, and digital asset exposure.
USD Coin — a US dollar stablecoin issued by Circle, backed by cash and short-term US Treasury securities. Monthly Big Four-attested reserves. The most widely used stablecoin for regulated institutional and cross-border payments.

Common questions about payments, FX, and digital assets for business.
SWIFT is a global messaging network used for international bank transfers between countries worldwide. SEPA is a regional scheme covering 36 European countries that enables fast, low-cost euro transfers within that zone. Most international EUR payments outside Europe still route through SWIFT.
A Virtual Asset Service Provider — a regulated entity offering digital asset services such as exchange, transfer, or custody. VASPs must comply with AML/KYC obligations and, in most jurisdictions, the Travel Rule.
The Travel Rule requires VASPs to share originator and beneficiary information for transactions above a threshold — the same principle as SWIFT messaging data applied to digital asset transfers.
They describe the same account from different perspectives. A nostro account is an account your bank holds at a foreign bank in a foreign currency (“ours”). A vostro account is what the foreign bank calls that same account (“yours”). Both are central to how correspondent banking works.
