RaboDirect says the rate for its on demand personal savings account will be cut from 4.3% to 4% on balances from €1 to €1m.
The bank says that this follows the recent ECB rate changes, although it is not passing on the full decrease.
RaboDirect's general manager Roel van Veggel says that the rate change was expected given the ECB interest rate decreases in recent weeks.
