Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Airwallex

  • Airwallex is a licensed payments firm rather than a bank, so balances sit in safeguarding accounts at partner banks and are not covered by deposit guarantee schemes, which means a treasury policy that requires insured deposits cannot hold operating cash there.
  • Available currencies, local account details, card programmes and product features differ by the entity you contract with, so a feature demonstrated to a customer in Australia or Singapore may simply not exist for the same company registered in another country.
  • Onboarding is subject to compliance review and whole categories of business are declined or later offboarded, and because the account may hold operating cash, a compliance freeze during a review is a business interruption rather than an inconvenience.
  • Foreign exchange is quoted as interbank plus a markup, which is cheaper than a high street bank but is still a spread that widens on less liquid pairs and on smaller amounts, so the saving assumed in the business case should be checked against the pairs you actually trade.
  • Support is largely ticket and chat based with account management reserved for larger customers, so when a payment is stuck the resolution path is a queue rather than a named person, which is a poor fit for time critical settlement.

Modern Treasury

  • You must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.
  • Pricing rests on an annual minimum commitment, and companies that miss their volume forecast pay the minimum regardless, which makes the headline per-transaction rate close to irrelevant in year one.
  • Supported bank connectivity is a finite list, so if your bank is not on it you are either waiting for an integration or changing banks, which is a far larger project than adopting the software.
  • It is software over banking, not banking, so it does not solve card issuing, deposit accounts or the licensing questions that a company embedding financial products still has to answer elsewhere.
  • The ledger is genuinely good but adopting it properly means making it the source of truth for balances in your product, which is a significant application change rather than a payments integration and is where implementations run long.

Answered from the vendors’ own pages

Airwallex: Is Airwallex a bank?

No. It holds payment institution, electronic money or equivalent licences in the markets it serves. Funds are safeguarded at partner banks rather than being deposits, and deposit insurance schemes do not apply.

Modern Treasury: Is Modern Treasury a bank or a banking as a service provider?

Neither. You hold your own bank accounts and it is software over them. That avoids sponsor bank concentration risk but means you need the bank relationship yourself.

Airwallex: Can it replace my business bank account?

For many operating flows it can, but consider what you lose: no deposit protection, no lending relationship, no cash or cheque handling, and some counterparties and government bodies still expect a conventional bank account. Most users run it alongside a bank rather than instead of one.

Modern Treasury: What does it cost?

Not published. A platform access fee plus usage fees across rails, on an annual term with a single minimum commitment. Negotiate the minimum, not the per-transaction rate.

Airwallex: Which countries can open an account?

It serves entities registered in a defined list of markets across Asia Pacific, Europe, the United Kingdom, the Middle East and North America, and the list changes. Check for your specific country of incorporation, because the answer determines both eligibility and feature set.

Modern Treasury: Which rails are supported?

ACH, wires, RTP, FedNow, push to card, cheques and stablecoin payments, subject to what your bank supports.

Airwallex: Does it connect to my accounting software?

It integrates with the mainstream cloud ledgers so transactions feed through rather than being imported by hand. Confirm the integration covers all the currencies you hold, since multi currency handling in the ledger is a separate question.

Modern Treasury: Do we still need our own compliance programme?

Yes. KYB, KYC and transaction monitoring are included in the platform, but you are the one holding the accounts and the regulatory obligation sits with you and your bank.

Airwallex: How does the foreign exchange rate compare with a bank?

Materially better than a typical business bank's retail rate on major pairs, because it is quoted as interbank plus a stated markup. The gap narrows on thin currency pairs and small amounts, so test with your real volumes.

Airwallex: Are the cards accepted everywhere?

They are issued on the major networks and behave like ordinary company cards for most spend. Some merchants, particularly for deposits and car hire, treat prepaid style issuance differently, so do not assume parity with a bank credit card.
