Wise is an EMI, not a bank
Wise (UK Wise Payments Ltd and EU Wise Europe SA) is authorised as an electronic money institution. EMIs cannot legally take deposits. When you hold a balance at Wise, it is customer e-money — legally distinct from a bank deposit.
By EMI rules, Wise must safeguard 100% of customer funds — typically by placing them in a segregated account at a major credit institution (Barclays, J.P. Morgan, others). The funds are separate from Wise's operating capital.
Safeguarding vs insurance
If Wise failed, the safeguarding rules require that customer funds be returned from the segregated account at the partner bank. This is not insurance — there is no statutory payout window (DGS commits to 7 days; safeguarding has no such commitment), no state-backed top-up if the safeguarded amount falls short, and the process of returning funds typically takes months.
In practice, no EMI of Wise's size has failed. Wise is a listed public company with audited accounts, Tier-1 capital ratios well above requirements, and transparent public reporting. The structural risk is real but has not historically materialised.
When should you care
Parking €10,000+ for long periods. Use a DGS-protected bank (N26, Revolut) instead.
Receiving a salary. Some EU jurisdictions don't accept a Belgian IBAN for payroll. Use a local-IBAN bank.
Everyday cross-currency spending, small transfers, business receipts. Wise is excellent — the protection gap is a minor concern at small balances.
Verdict
Wise is safe in the sense that matters — a regulated, audited, listed institution with robust safeguarding. But it is not a bank; don't treat it as one. Pair it with a DGS-protected account for your primary euro balance.
