What is EMI (Electronic Money Institution)?

An Electronic Money Institution is a regulated financial firm authorized to issue electronic money and provide payment services without being a full bank. EMIs power most modern multi-currency business accounts.

How it works

An EMI is licensed under specific frameworks — EU Electronic Money Directive 2009/110/EC (EMD2), the UK's analogous Electronic Money Regulations 2011, similar regimes in Singapore (Payment Services Act 2019), Australia (ASIC), and others. The licence permits the institution to:

  • Issue electronic money — store value as a balance redeemable on demand.
  • Provide payment services — issue payment accounts, execute transfers, issue cards, perform FX, etc.

What an EMI cannot do (vs. a full bank):

  • Lend customer funds — EMIs cannot use customer deposits for lending or investments. Funds must be safeguarded.
  • Take deposits in the legal-banking sense — funds are e-money, not bank deposits.
  • Access deposit insurance — customer funds are not protected by the EU DGS, UK FSCS, or US FDIC schemes the same way bank deposits are.

Safeguarding

EMI customer funds must be segregated from the EMI's own balance sheet, typically by:

  • Holding in segregated client accounts at top-tier banks (the EMI is the account holder; client funds are held on behalf of customers).
  • Investing in low-risk instruments (highly-rated short-term securities) for the same purpose.
  • Bank insurance in some jurisdictions adds an extra protection layer.

If the EMI fails, segregated funds are returned to customers (subject to the bankruptcy administration process). They aren't lost as deposit-insurance-protected funds would be — but the recovery process is slower and messier than DGS / FSCS / FDIC payouts.

Major EMIs serving founders

Wise (formerly TransferWise)EU + UK + multipleMulti-currency for individuals + small businesses; FX market rates
Revolut BusinessEU + UKEU-resident SMEs; integrated card + accounting

Note: some "EMIs" in the popular sense (Mercury, Brex) are actually banking-as-a-service partnerships with chartered US banks (Choice Financial, Evolve Bank, Column, etc.) rather than EMI-licensed entities. The legal structure differs from EU/UK EMIs but the user experience is similar.

Why founders prefer EMIs over banks

  • Fast onboarding — minutes to days vs. weeks for traditional banks.
  • Multi-currency by default — hold and transfer in 30+ currencies without nostro hassles.
  • Lower fees — local rails (SEPA, Faster Payments, ACH) instead of correspondent SWIFT chains.
  • Modern UX — clean dashboards, API access, integrations with Stripe, Xero, QuickBooks.
  • Cards — issued instantly, often included in the account.

Trade-offs:

  • No deposit insurance in the same way as banks.
  • Limited credit / lending — no overdrafts, business loans, or merchant financing typically.
  • Sensitive to compliance flags — fast off-boarding without much due process.

Examples

  • French founder's Wyoming LLC opens at Mercury. Onboarding ~3 days. USD account with routing + account number, no in-person visit. Receives Stripe payouts, Stripe-issued debit card, ACH payments to vendors. Total operating cost minimal compared to traditional US bank.
  • UK e-commerce business uses Wise Business + Revolut Business. Wise for FX-heavy supplier payments (real market rates); Revolut for everyday EUR/GBP operations + cards. Diversification protects against single-EMI off-boarding risk.

Common mistakes

  • Treating EMI as bank. No deposit insurance, no lending, more compliance volatility.
  • Concentrating all funds in one EMI. Off-boarding risk is real. Maintain at least 2 active accounts across different providers.
  • Mismatched declared activity vs. observed flow. Onboarding KYC asked about your business; large flows that don't match the declared activity trigger flags. Update declarations as business evolves.
  • Ignoring the safeguarding bank. EMIs hold customer funds at partner banks. The partner bank's failure or restrictions can cascade to EMI users (e.g., the SVB collapse 2023 affected several EMIs whose safeguarding was at SVB).

Frequently asked questions

Are EMIs banks?

No. They issue e-money and provide payment services under EMI licences (UK FCA, EU Directive 2009/110/EC, equivalents elsewhere). They cannot lend customer funds the way banks do.

Are my funds safe?

EMIs must safeguard customer funds, typically in segregated accounts at top-tier banks. They are not protected by the DGS, but they are also not lent out.

Why are EMIs stricter on KYC?

Lower margins, higher reliance on automated risk models, and tighter regulatory scrutiny push EMIs to off-board ambiguous customers fast. Build the relationship cleanly from day one.

Which EMI for a US LLC?

Mercury, Relay and Wise are the most common, depending on residency and use case. Each has its own approval criteria — diversify if you depend on banking.
