Key takeaways

• Sending a US$200 remittance still costs a global average of 6.3%, against a G20 target of 3% by 2030.¹ Business cross-border payments carry the same layered intermediary costs, and those costs come out of margin.

• Brex now operates as a Capital One subsidiary following a US$5.15 billion acquisition that closed in April 2026. Pedro Franceschi remained CEO.² The platform focuses on bank-led underwriting and mid-market stability.

• Airwallex holds and spends funds in 20+ currencies with local account details, allowing cross-border businesses to avoid forced conversion. Brex holds balances primarily in USD.

The line between fintech and institutional banking has thinned considerably. Modern finance teams now have to decide whether their priority is balance-sheet stability or global infrastructure. This comparison covers how Airwallex and Brex differ on multi-currency accounts, cards, treasury, and fit by industry.

The bottom line about Airwallex vs Brex

The decision between Airwallex and Brex rests largely on where a company's customers and suppliers sit.

Airwallex suits businesses running both domestic and cross-border operations. The platform gives companies a global account with local details in 20+ currencies. A business can collect and spend across those currencies without forced conversion. Authentic Vacations, a travel operator, saved roughly US$10,000 a month on FX after moving to Airwallex.³ Airwallex also supports eCommerce sellers on Shopify and SaaS companies with teams across Europe and Southeast Asia.

Brex serves venture-funded firms that want high-limit credit and domestic spend controls. Brex provides a United States account with global spending capability. The platform now sits inside Capital One's balance sheet.

For companies comparing options, Airwallex ranks among the best Brex alternatives for managing global spending and foreign exchange seamlessly.

Note: Airwallex is a fintech company, not a bank. U.S. customer funds are held with FDIC-insured partner banks, including Evolve Bank & Trust, and are eligible for FDIC pass-through insurance of up to $250,000 per qualified customer account and banking institution.

Airwallex vs Brex: Key feature comparison

Multi-currency management and local accounts

Airwallex and Brex take different approaches to non-USD currencies. Airwallex is an international platform with local capabilities. Brex is a domestic platform with international reach.

Airwallex multi-currency accounts allow businesses to generate local bank details in 20+ currencies. A company can give its United Kingdom customers a GBP account number and sort code. Those customers pay a local business. Funds land in the GBP balance without conversion or wire fees. That matters most for companies collecting revenue in more than one currency.

Brex focuses on a unified experience for domestic companies. The platform issues cards in 50+ countries and supports local-currency billing for employees. It does not offer deep local receiving accounts. Brex covers the case where a company only needs to spend money abroad.

Corporate cards

Airwallex Corporate Cards suit businesses spending across borders. The cards carry 0% foreign transaction fees and draw directly from multi-currency balances, avoiding the markup most domestic cards apply to international spend. Employees can spend in 60+ markets straight from the balance. Every eligible purchase earns 2% uncapped cashback, which benefits firms with heavy digital marketing spend on platforms such as Meta or Google.

Airwallex also applies AI inside the spend workflow rather than alongside it. The Expense Policy Agent reviews and enforces expense policy across entities, currencies, and languages, which cuts manual review at month-end.

Brex has built out a comparable AI framework with Agents on Brex, which reads receipts, audits expenses against policy, and initiates payments. Brex also leads on credit limits, underwriting against cash on hand and revenue rather than credit history.

Yield products and treasury

Airwallex Yield offers up to 3.70% on USD balances, quoted as a 7-day annualized rate net of fees as of September 2026. The highest rate requires an Accelerate subscription. There are no lock-up periods, and funds generally settle back to cash balances within one to two business hours. Balances sit in the JPMorgan U.S. Government Money Market Fund. Returns are not guaranteed, and money in the fund is not FDIC-insured. A business can earn on USD while it waits to convert for a EUR supplier payment.

Brex advertises up to 3.89%, but that top rate applies to balances of $20M+. Smaller balances earn closer to 3.5%, and part of the return is a Brex-paid bonus on top of the fund yield.

Should Capital One's acquisition change the decision?

Capital One acquired Brex for US$5.15 billion in a deal that closed in April 2026. The price sat roughly 60% below Brex's US$12.3 billion peak valuation in 2021.² That reset reflects a broader shift in how the market prices growth.

The acquisition brings institutional backing. Brex is no longer an independent company subject to the funding pressures of private fintech. It now sits inside a Tier 1 financial institution, which adds balance-sheet stability for conservative CFOs. Capital One's depository base lets Brex hold stable credit limits. Onboarding now involves more documentation than it did in Brex's early growth years.

How to evaluate Airwallex vs Brex for a business

Finance leaders should start with last year's transaction data. The two figures that matter are the share of revenue collected in non-USD currencies and the volume of global vendor payouts. Companies with more than 20% international activity tend to benefit most from Airwallex, because Airwallex charges a 0.5% markup on major currencies while Brex applies a card spread of roughly 3% on international spend.

Companies that need a multi-currency wallet should plan the switch timeline carefully to ensure corporate card coverage does not lapse mid-transition. Brands have been prioritizing durable financial infrastructure over high-limit credit facilities.

For eCommerce and marketplace models, Airwallex's local rails provide a structural advantage. Settlement speed and multi-currency holding are hard to replicate on a traditional bank stack.

Is Airwallex or Brex better for different industries?

Global eCommerce and marketplace sellers

Airwallex fits this category well. eCommerce margins are thin, and forced conversion eats into them. Marketplaces commonly convert European payouts to USD at a rate that includes a 2% to 3% fee. A seller using an Airwallex EUR Global Account receives euros natively and can pay European suppliers or VAT from that balance.

Venture-backed SaaS startups

Brex remains a common choice in the venture ecosystem. High credit limits give growth-stage companies working capital for headcount and marketing. Brex also offers a high-yield home for funding rounds and a founder network. Many SaaS firms still run Airwallex alongside or instead, because paying international developers and collecting global subscription revenue costs less at a 0.5% markup than at a 3% card spread.

Scaling service firms and agencies

Airwallex suits agencies with a distributed workforce. An agency can send free batch transfers to 120+ countries over local rails, covering contractors in the Philippines, designers in the UK, and developers in Poland. SWIFT transfers reach 200+ countries and cost US$15 to US$25 per transfer. Agencies can reimburse remote employees in local currency without taking an FX loss.
