Belgian Savings Rates Rise: Which Banks Offer Best Deals?

Several Belgian banks have raised interest rates on savings accounts in recent weeks, with headline rates now exceeding 3% for the first time in years. But as RTBF reports, the reality is far more nuanced than the eye-catching figures suggest. Most of these increases apply only to accounts with strict conditions, while standard savings accounts remain stubbornly low.

Who’s Offering What?

VDK Bank currently leads the pack with a rate of 3.17% on its “Rythme” (Ritme) account, effective July 15. This consists of a base rate of 1.67% and a fidelity premium of 1.50%, with monthly deposits capped at €500, according to L’Avenir.

KBC follows closely at 3.15% on its Start2Save and Start2Save4 accounts (effective August), also with a €500/month limit.

Belfius offers 3.10% on its Flow account (effective July 1), with a slightly higher monthly cap of €600, as DHnet/Belga reports.

ING Belgium raised rates on its regulated savings accounts effective July 1. The ING Epargne Tempo (Cat. B) now offers a base rate of 1.60% plus a 1.50% fidelity premium, according to an ING press release.

BNP Paribas Fortis launched its “Boost” account in early May at 2.90%, while Argenta raised its Groeirekening to 3.00% in early June.

The Fine Print: Fidelity Premiums and Deposit Caps

The catch with these high-rate accounts is twofold. First, the advertised rate is split between a base interest rate and a fidelity premium — the latter is only earned if money remains untouched for a full 12 months. Second, monthly deposits are capped at €500–600, making these accounts unsuitable for anyone looking to deposit a lump sum.

As RTBF journalist Jean-François Noulet puts it: “Is the rate war on savings accounts underway between banks in Belgium? If many savers hope so… the reality is much more nuanced.” These accounts are primarily “produits d’appel” — loss leaders designed to attract new customers who may then open other, more profitable accounts.

For regular savers with standard accounts, the picture is far less rosy. Classic savings accounts at major banks offer meager returns: BNP Paribas Fortis’s basic account pays just 0.50% (0.30% base + 0.20% fidelity), while Belfius’s basic offering sits at 0.60%.

Belgian Savers: The Worst Off in the Eurozone?

According to economist Eric Dor of IESEG School of Management, the average interest rate on savings deposits in Belgium was just 0.68% in May 2026. This compares unfavorably with Luxembourg (1.73%), France (1.39%), the Netherlands (1.24%), and even Germany (0.69%). Only Cyprus, Bulgaria, and Finland had lower rates.

Belgian savers face a double penalty. Not only are their savings rates among the lowest in the Eurozone, but inflation in Belgium stood at 3.40% in June 2026 — among the highest in the currency bloc. The result? A real loss of approximately 3.28% on savings over one year, compared to a 1.41% loss for French savers.

Why Are Belgian Rates So Low?

Belgian banks have been notably slow to pass on ECB rate increases to depositors. The European Central Bank raised its key rate to 2.25% on June 11, 2026, yet the pass-through to savings accounts has been limited. Nino Demour, CFO of VDK Bank, explained in an earlier interview that “savings account rates are mainly linked to short-term ECB rates,” which have remained stable.

However, the competitive dynamics appear to be shifting. The succession of rate announcements — from BNP Paribas Fortis in May to VDK Bank in July — suggests banks are jostling for market share, particularly among younger savers and families looking to build regular savings habits.

What Should Savers Do?

For those who can commit to saving €500–600 per month and leave the money untouched for a year, the new high-rate accounts offer genuine value. They are particularly well-suited for parents saving for children or individuals building an emergency fund gradually.

But for savers with larger capital to deposit, these accounts are not the answer. Alternatives include term deposits, bond funds, or diversified investment portfolios — though each comes with its own risk profile.

The Bottom Line

Even the best savings rates in Belgium — at 3.17% — barely keep pace with inflation. While the recent rate increases are a welcome development for disciplined savers, they do not solve the fundamental problem: Belgian savers are losing purchasing power on their deposits. As economist Eric Dor notes, the combination of low savings rates and high inflation means Belgian savers are doubly penalized compared to their European neighbors.

The question now is whether this mini “rate war” will spread to standard savings accounts, or whether it remains confined to promotional products designed to attract a specific segment of customers.
