Cross-Border B2B Payments: 2026 Guide

Stablecoins have moved far beyond crypto trading. In June 2026, the stablecoin market is worth more than $315 billion, with USDT and USDC accounting for most of the supply. At the same time, businesses are under pressure to move money across borders faster, reduce operational costs, and gain better visibility into payments.

That shift is changing how B2B cross-border payments work. Traditional correspondent banking remains common, but businesses are increasingly looking at local payment rails, real-time payment networks, and stablecoin-based infrastructure to move value across countries.

This guide explains how B2B cross-border payments work in 2026, why they are often slow and expensive, and what to look for in modern cross-border payment solutions. You'll learn how traditional banking compares with newer payment models and how providers such as Merge combine local fiat rails and stablecoin infrastructure to support global cross border B2B payments.

What Are B2B Cross‑Border Payments?

B2B cross‑border payments are transactions where one business pays another in a different country and, usually, a different currency. They cover supplier payments, payroll, marketplace payouts and treasury transfers.

Cross-border payments remain one of the largest segments in global finance. According to FXC Intelligence, global cross-border payment flows were worth roughly $194 trillion in 2024 and are projected to reach $320 trillion by 2032. Within that total, non-wholesale payments accounted for around $40 trillion and are expected to exceed $64 trillion by 2032. J.P. Morgan estimates that corporations move approximately $23.5 trillion across borders each year, highlighting the scale of demand for faster and more transparent payment infrastructure.

Modern B2B flows resemble an iceberg. The visible part is a supplier invoice or an intercompany transfer. Beneath the surface lies a complex network of banks, payment networks and compliance checks. Every jurisdiction has its own rules, currencies and cut‑off times, so moving money from Amsterdam to Singapore means more than simply sending euros. It means navigating FX conversion, correspondent banks, local settlement systems and multiple layers of fraud and sanctions screening.

How Do B2B Cross‑Border Payments Work?

In the legacy model, a B2B international payment passes through a chain of banks. A payer instructs its bank to send money abroad. That bank may convert currency and send the instruction across the SWIFT messaging network to a correspondent bank that holds accounts for both sides. If the sending and receiving banks don’t have a direct relationship, other intermediaries join the chain.

Each bank validates compliance, applies its own fees and FX spreads, and adds time to settlement. SWIFT reports that about 90% of cross‑border payments reach the destination bank within one hour thanks to its GPI service, yet end‑to‑end settlement can still take one to five business days, depending on cut‑off times, correspondent chains and currencies.

The legacy route introduces three major frictions:

• Extra costs: Each intermediary bank adds transfer fees and embeds mark‑ups in FX rates. Businesses are paying unnecessarily high cross‑border fees because they process payments through their home country rather than where their customers or entities are located.
• Settlement delays: Every hop introduces a new cut‑off time and compliance check. Even though 90% of payments reach the recipient bank quickly, the actual crediting of funds often occurs much later.
• Visibility gaps: Once funds leave the sender’s bank, tracking their progress is difficult. Payment status updates may take days, making cash‑flow forecasting harder for treasury teams.

The Modern Model: Local Fiat Rails + Stablecoins

New infrastructure reduces the need for long correspondent chains. Instead of hopping from bank to bank, both sides use local payment rails. For example, a business in the Netherlands can pay euros into SEPA Instant, while the supplier in Brazil receives Brazilian real via Pix. Value moves globally in between, often via stablecoins, which provide an “always‑on” bridge between local systems. This model has three advantages:

• Faster settlement: Local real‑time payment rails such as SEPA Instant and the UK’s Faster Payments settle domestic transactions in seconds. FedNow in the US and UPI in India offer similar speed. When combined with stablecoins, value can travel 24/7 between regions without waiting for banking hours.
• Transparency: Stablecoin ledgers provide real‑time tracking of funds, reducing uncertainty about where money is in transit. This helps reconciliation and cash‑flow planning.
• Programmability: Programmable payments enable split disbursements and automated sweeps. Enterprises can route funds based on rules, rather than manually choosing rails.

Why B2B Cross‑Border Payments Are Slow and Expensive

Many of the challenges in B2B cross-border payments come from the infrastructure behind them. Multiple intermediaries, regulatory checks, and disconnected systems can increase costs and slow settlement.

Hidden Fees and Opaque FX Spreads

Foreign exchange remains the single biggest source of hidden cost in international payments. Traditional banks embed mark‑ups into exchange rates and layer on transfer fees, making it almost impossible for finance teams to predict the true cost of a cross‑border transaction.

Many companies default to sending payments from their home jurisdiction, even when the beneficiary is elsewhere. This leads to unnecessary intermediary fees and FX spreads. Corporations move $23.5 trillion across borders annually, so small basis‑point mark‑ups add up quickly.

Compliance and Screening Overhead

Each cross‑border payment is subject to sanctions screening, anti‑money laundering (AML) and know‑your‑customer (KYC) checks. A 2025 survey by the Association of Finance Professionals found that 79% of US organisations faced payment fraud attempts in 2024.

Every transaction that fails STP requires manual intervention, slowing settlement and increasing error risk. Globally, over 19,000 tax jurisdictions add further compliance complexity. As regulations tighten, businesses must navigate different KYC and AML requirements in each market.

Limited Visibility and Reconciliation Pain

In the legacy system, payment status updates are inconsistent. SWIFT data show that while roughly 90% of payments reach the recipient bank within an hour, the actual crediting of funds often occurs three to five days later. For finance teams, that delay translates into cash‑flow uncertainty. Matching incoming payments to invoices across multiple currencies and entities becomes a manual, error‑prone process. Low STP rates force staff to chase down confirmations and manually reconcile cross-border transactions across ERP systems and bank portals.

Trapped Capital and Nostro Accounts

To ensure smooth cross‑border settlement, banks hold foreign accounts (known as “nostro” and “vostro” accounts) with partners. Corporations often pre‑fund these accounts to guarantee liquidity. With global corporations moving trillions across countries each year, the amount of capital locked in nostro accounts is constantly fluctuating but consistently high. This trapped capital cannot be used for working‑capital needs or investment until the settlement is complete. The inefficiency is a key driver for alternatives like stablecoins, which allow value to move without large pre‑funded balances.

Types of B2B Cross‑Border Payment Solutions in 2026

Correspondent Banking

SWIFT is the global messaging network used by more than 11,500 institutions across over 200 countries. While GPI enhancements mean that 90% of payments reach the destination bank within an hour, full settlement still depends on correspondent chains, cut‑off times and currency availability. The model is well established but remains slow and expensive.

Card Networks

Business card rails allow enterprises to pay suppliers with credit or procurement cards. Virtual cards, which create a single‑use card number for each payment, are growing rapidly. Global virtual card payments are forecast to grow 235% by 2029, rising from $5.2 trillion in 2025. Cards are convenient for travel and ad‑hoc purchases but carry interchange fees and may not suit high‑value B2B transfers.

Money Transfer Operators and Fintech Rails

Modern providers combine local payment rails, FX liquidity and user-friendly interfaces. They connect to major networks such as ACH in the US, SEPA in Europe, Faster Payments in the UK, Pix in Brazil and UPI in India, while broader providers like Merge support local payment coverage across 80+ countries. These rails can speed up domestic settlement and, when orchestrated across borders, reduce settlement windows from days to hours. The main limitation is coverage, so businesses should check whether one provider can support their priority markets.

Stablecoin‑Based Infrastructure

Stablecoins pegged to fiat currencies provide a real-time bridge between local payment systems. After the GENIUS Act of July 2025 created a unified regulatory framework for fiat-backed stablecoins, institutional adoption accelerated. Businesses send local currency to a regulated provider, value moves across a blockchain as a stablecoin, and the recipient receives local fiat on the other side.

This is the model used by Merge. The platform combines stablecoin rails with local fiat payment networks, allowing businesses to collect and pay out in local currencies while stablecoins move value globally in between. Settlement is available 24/7, and payment flows can support features such as automated reconciliation, split payments, and sub-account structures. As with any stablecoin-based infrastructure, businesses should work with regulated providers and understand the compliance requirements in the markets where they operate.

What to Look for in a B2B Cross‑Border Payment Solution

When evaluating cross‑border payment providers, finance teams should consider:

• Coverage: Does the platform cover your high‑volume corridors and currencies? Look for access to major currencies and the ability to settle in local rails such as ACH, SEPA, Faster Payments, UPI, Pix and others.
• Compliance: Built‑in KYC/KYB, transaction monitoring, PEP screening and sanctions checks are essential. Global regulation is tightening, and fines for non‑compliance are substantial.
• Reconciliation and reporting: Automated reconciliation across currencies, sub‑accounts and entities reduces manual work and speeds month‑end close. Detailed reporting supports audit and tax requirements.
• API and integration: A single API that integrates with your ERP and treasury systems ensures straight‑through processing and reduces IT complexity. Look for SDKs and webhooks for real‑time status updates.
• Pricing: Transparent, flat‑fee pricing helps you forecast costs. Beware of hidden FX spreads and intermediary charges.
• Settlement speed: Real‑time rails with 24/7 availability improve cash flow and working‑capital efficiency. Near‑instant settlement reduces the need for large pre‑funding balances.

How Merge Approaches B2B Cross‑Border Payments

Merge combines stablecoin rails with local fiat payment networks. Because both sides use local fiat rails with stablecoins moving value in between, senders and recipients continue to transact in fiat without changing how they operate. The platform offers:

Local Fiat In, Local Fiat Out: Stablecoins in Between

Businesses collect and pay in local fiat. Stablecoins move value globally under the hood. Clients avoid opening foreign bank accounts or managing nostro balances. This model can reduce settlement times from days to near‑instant.

A Single API Platform

Open accounts, initiate swaps and trigger payouts through a unified integration. Instead of managing multiple banking relationships, businesses interact with one API. Merge can connect to multiple local payment rails and route payments via the optimal rail for each corridor.

Built‑in Compliance

KYC/KYB, transaction monitoring, PEP screening, sanctions checks and regulatory workflows run in the background. Compliance controls are updated continuously to reflect local regulations.

Fast Global Payouts

Merge allows clients to collect locally and pay out globally. It connects to local payment rails worldwide and can settle via ACH, SEPA, Pix, Faster Payments, UPI and more, with fast settlement to major markets, same-day payouts to supported corridors, and near-instant stablecoin disbursement where local rails are slower. Structured reconciliation data and reporting support sub-accounts and split payments. Settlement is available 24/7 with no banking‑hour restrictions.

Reconciliation and Sub‑Accounts

Dedicated sub-accounts keep funds segregated and traceable, so each flow maps cleanly to a counterparty, entity, or cost centre. Merge surfaces a single, structured payment-data layer that makes matching structural rather than manual, giving finance teams the visibility and data hooks to automate reconciliation on clean data. Configurable rules support sweeps and splits by client or transaction type

Transparent Pricing

Merge charges with flat fees that businesses can forecast. There are no hidden surprises in FX spreads or intermediary charges.

Regulated Status

Merge operates as a Virtual Asset Service Provider (VASP) regulated by the AMF in France. It also holds an EMI licence, allowing it to issue fiat accounts to customers in Europe and provide access to SEPA Instant, SEPA Credit Transfer and TARGET2 transactions. Merge does not hold client funds or control wallets; it orchestrates payments across banks, local rails and stablecoin issuers. Every transaction includes automated PEP screening, sanctions checks, KYC/KYB and ongoing transaction monitoring.

Marketplace Line

For platforms that collect and split funds across buyers, sellers and regions, Merge can simplify reconciliation and reduce complexity by handling settlement, sub‑account management and splits through a single integration.
