Under the Act on Mortgage Lending to Consumers, no. 118/2016, the Central Bank of Iceland is authorised, subject to prior approval by the Financial Stability Committee, to adopt rules restricting mortgage lending to consumers. The Act provides for the application of various macroprudential instruments, cf. Chapter VII of the Act, aimed at preserving financial stability, strengthening lenders and consumers’ resilience to imbalances in the real estate market, and mitigating systemic risk over the long term.
Borrower-based measures currently in effect
Loan-to-value ratios for mortgage loans
Rules on Maximum Loan-To-Value Ratios for Mortgage Loans to Consumers have been in effect in Iceland since July 2017. The rules provide greater scope for financing first-time home purchases by allowing a higher maximum loan-to-value ratio.
The loan-to-value ratio indicates the proportion of the market value of a residential property that is pledged as collateral for loan financing. It is defined as the total amount of mortgage loans secured by a specific property as a percentage of the market value of that property. The market value is generally determined based on the purchase price specified in the purchase agreement or accepted purchase offer.
Debt service-to-income ratios for mortgage loans
Rules on Maximum Debt Service-to-Income Ratios have been in effect since December 2021. The rules provide greater scope for financing first-time home purchases by allowing a higher maximum debt service-to-income ratio. In addition, the rules provide for a general exemption from the maximum debt service-to-income ratio. Lenders may use this exemption to grant consumers loans whose debt service exceeds the specified limits.
The debt service-to-income ratio for mortgage loans is a measure of household liquidity risk and indicates the proportion of a borrower’s income used for servicing mortgage loans. It is defined as the monthly debt service on mortgage loans as a percentage of monthly disposable income. Debt service refers to principal and interest payments on all the borrower’s mortgage loans, while disposable income refers to the borrower’s expected permanent income.
Central Bank of Iceland Special Publication no. 20/2025 provides a comprehensive discussion of the application of borrower-based measures in Iceland and places them in an international and academic context considering the experience gained in recent years. The publication is intended to make a useful contribution to the discussion of borrower-based measures, their application, and their role in economic policy.
Restrictions | General | First-time buyers | General exemption |
|---|---|---|---|
Maximum LTV ratio | 80% of the market value of the underlying property* | 90% of the market value of the underlying property* | |
Maximum DSTI ratio | 35% of disposable income** | 40% of disposable income** | 10% each quarter of the total amount of granted mortgage loans |
* Property value according to purchase agreement or accepted purchase offer. If there is no purchase agreement or accepted purchase offer, the ratio shall be based on the official property value or fire insurance value as listed by the Housing, Construction and Planning Authority, or the appraised value as determined by a certified real estate agent, in accordance with the lender’s lending rules.
** Disposable monthly income is defined in the law as a borrower’s expected sustained income, net of direct taxes and expenses. Debt service on non-indexed mortgage loans shall be calculated based on the contractual interest rate or a minimum interest rate of 5.5%, whichever is higher, and a maximum loan term of 40 years, while debt service on indexed mortgages shall be calculated based on the contractual interest rate or a minimum interest rate of 3%, whichever is higher, and a maximum loan term of 25 years.
