According to their official statement, Bank Norwegian interest rate was just increased to 1.8% on savings accounts effective today, November 4th, 2022.
Last September, the central bank increased the repo rates by 1%. Now it is more expensive to borrow money (loans and mortgages will go up), but there is also more incentive to save money in bank accounts (similar to what happened during 2013-2014).
Bank Norwegian savings accounts had an interest rate of 1.3% and 1.5% until now, which is increased to 1.8%, regardless of how much you deposit.
