Deposits exceeding NOK 2 million that are not covered by the guarantee scheme are not necessarily lost if the bank is liquidated. The depositors will have a claim on the estate, and must therefore wait until the estate processing is finalised before they will know whether the excess amount has been covered. There is also extended and unlimited coverage for deposits that come from special life events, such as the sale of a home, inheritance or insurance payout. See more information here.
If you have more than NOK 2 million in the bank, you can spread your deposit across several banks if you want the entire amount covered by the deposit guarantee.
