Trade Republic tops 2026 Spanish high‑yield account rankings

Trade Republic, a German‑based fintech, offers the highest annual percentage rate (TAE) at 3.04% with no salary‑deposit requirement. The account is fully online, pays interest daily, and deposits are covered by Germany’s guarantee scheme up to €100,000.

Openbank, backed by Grupo Santander, provides a 2.50% TAE for the first 12 months with no maximum balance limit, but the promotion requires a Bizum transfer to the bank. Bankinter’s digital account also delivers a 2.50% TAE (2.47% TIN) on up to €100,000 of balances, without any payroll or consumption‑linked conditions.

These three products were ranked as the best remunerated accounts for 2026, with Trade Republic in first place, Bankinter second, and Openbank third, offering savers a way to offset the July CPI rise of 3.5% by earning interest on idle cash.
