What can you do with it?4 ideas

Getting started

Savings rate versus inflation

Put the average interest rate on household savings next to CBS inflation. You see in which years savers lost purchasing power.

Getting started

How much do households save?

Table 5.2.6 gives Dutch household savings at banks. The household savings dashboard also shows deposits, withdrawals and credited interest over the years.

Advanced

Which fixed-rate period do buyers choose?

DNB breaks down new bank mortgages by fixed-rate period. According to DNB, shorter fixed periods became more popular again in 2022 and 2023 as rates rose fast.

Advanced

Pension fund funding ratio per month

DNB publishes the policy funding ratio of pension funds every month. Put it next to the interest rate term structure to see how strongly rates feed through.

Interesting combinations

maand

Do house prices follow mortgage rates?

Put the rate on new mortgages next to the CBS price index of existing owner-occupied homes, per month. Look at the lag between the two.

Combine with CBS StatLine

How does the Dutch savings rate compare with inflation elsewhere in Europe?

Eurostat has harmonised inflation per country. Subtract it from the savings rate for a real rate.

ECB Data Portal not in the index yet
The same kind of bank and interest figures for all euro countries, with an open SDMX API without a key.

CBS looks at households themselves, for example in table 85162NED on the financial risk of mortgage debt among homeowners (2006–2024).

What to watch out for

API only with an account
The API requires a Mijn DNB account and a subscription key. As a user, DNB may contact you about changes or for feedback.
Not everything is in the API
DNB adds current tables to the API in phases. Tables that are no longer updated are only on the website.
Banks only
DNB doesn't collect mortgage rates from lenders other than banks, such as insurers and pension funds. Part of the market is missing from those figures.
Credit and note changes
The licence is CC BY 4.0: credit DNB, name the licence and say whether you modified the data. A modification may not suggest that DNB endorses it.
An interest rate isn't always the same rate
DNB distinguishes rates on new contracts from rates on existing contracts (the stock). The savings dashboard uses the average rate on existing contracts. Don't compare new with existing.
