Chasing Belgium's highest savings rate? Six things to check before you move your money
Almost every Belgian bank is now advertising a headline savings rate, and the temptation to shift your cash to whoever tops the table is real.
In 30 seconds
- Belgian regulated savings accounts pay a base rate plus a fidelity premium earned only on money kept for 12 consecutive months.
- Banks may legally advertise the base rate and fidelity premium combined, so a headline rate can hinge on not withdrawing.
- Interest is tax-free up to an indexed annual ceiling of roughly €1,000 per person; above it, 15% withholding tax applies to regulated accounts.
- Wikifin.be, run by the FSMA regulator, is the main official, non-commercial source for comparing how these rates work.
Belgian regulated savings accounts (gereglementeerde spaarrekening / compte d'épargne réglementé) pay interest in two components: a base rate that accrues daily and a fidelity premium earned only on funds left untouched for twelve consecutive months. Banks may advertise the combined figure, so headline 'highest rate' claims can obscure how much of the return depends on not withdrawing. Interest is tax-exempt up to an indexed annual ceiling (roughly €1,000 per person; the exact amount is set yearly), with 15% withholding tax (roerende voorheffing) above it on regulated accounts. The framework is federal and overseen by the FSMA, whose Wikifin.be portal is the main non-commercial reference. Deposits are protected up to €100,000 per person per bank under the federal deposit guarantee.
Background
Through the low-rate and negative-rate years of the 2010s and into the pandemic, Belgian regulated savings accounts largely sat near their legal minimum return, and savers earned almost nothing. As the European Central Bank raised rates from 2022 to counter inflation, deposit competition slowly returned. Belgian banks were repeatedly criticised — by consumer groups such as Test-Aankoop and by politicians — for being slow to pass higher rates through to savers, which made the eventual wave of higher, heavily marketed offers all the more conspicuous.
What to do
Before moving money: separate the base rate from the fidelity premium; check whether the top rate is promotional, new-money-only or capped; avoid switching before the twelve-month fidelity mark; confirm the current tax-free interest ceiling; compare on Wikifin.be or Test-Aankoop rather than a bank's own page; and keep balances within the €100,000 deposit-guarantee limit per bank.
