Why are mortgage rates rising and what does it mean for homeowners?
Higher central bank rates push mortgage rates up and tend to slow house price growth, so rising rates cut both ways for homeowners.
Covers: Explains the main drivers of rising mortgage rates, such as central bank policy, inflation, and bond market conditions, and their effects on monthly payments, affordability, and housing decisions. It does not provide personalized financial advice or predict future rate movements.

The short answer
Evidence-backed AI-prepared starting mapMortgage rates rise mainly because central banks raise policy interest rates to fight inflation, and those higher policy rates pass through to the rates lenders charge on mortgages. A study of the Czech Republic (2008–2024) found statistically significant transmission from the central bank's repo rate to mortgage rates and to lending activity, and identified episodes of price growth consistent with speculative bubbles. A ten-country panel study found that, after controlling for GDP growth and unemployment, a rise in the real interest rate had a negative effect on house price growth rates. Higher rates therefore cut both ways for homeowners: they raise the cost of new borrowing while tending to cool house-price growth.12

In brief
Central bank policy rates pass through to mortgage rates; in the Czech Republic this transmission was statistically significant from 2008 to 2024.1
Evidence-backedHigher real interest rates were associated with slower house price growth across ten countries, after controlling for GDP growth and unemployment.2
Evidence-backedGovernment borrowing can crowd out housing finance by competing for local credit, as found in Nigeria.3
Evidence-backedThe link between interest rates and long-run affordability is contested: Malaysia's study found no long-run cointegration for interest rate and recommended targeting money supply instead.4

What it means for you
Which fits you?
Pick the situation closest to yours. Each answer says what it rests on.
If you are about to take out a new mortgage
expect the rate you are offered to reflect the central bank's policy rate, since that transmission has been documented in the Czech mortgage market.1
Evidence-backedIf you already own a home and are watching its value
note that higher real interest rates have been associated with slower house price growth across ten countries, though the studies do not predict what happens in any single market.2
Evidence-backedIf you are weighing whether rate policy can fix affordability
the cross-country evidence suggests monetary policy is a poor tool for that goal because it distorts housing market dynamics.2
Evidence-backedIf you are looking at housing finance in a market with heavy government borrowing
the Nigeria findings suggest domestic debt can crowd out local credit and that higher rates suppress housing finance, so fiscal discipline and specialised housing finance instruments matter.3
Evidence-backedIf you are trying to judge affordability in a market like Malaysia
the evidence there points to money supply rather than interest rate as the long-run lever, so rate movements alone may not explain affordability.4

What pushes mortgage rates up
AI summary:Central bank policy rates pass through to mortgage rates, while government borrowing and other factors also shape housing finance.
Evidence-backed: The clearest driver in this material is central bank policy. When central banks raise their policy rates, mortgage rates follow: in the Czech Republic, changes in the central bank's repo rate were passed through to mortgage rates and to the volume of new mortgage loans, with statistically significant transmission linkages confirmed across 2008–2024. The cross-country study frames the 2020 rate cuts and the 2022 rate increases as a natural experiment, and finds a negative association between interest rate changes and house price changes in many countries.12
Evidence-backed: A second channel is competition for credit. A study using Central Bank of Nigeria, National Bureau of Statistics and World Bank data found that the crowding-out effect of domestic government debt was more pronounced because it competes directly in the local financial market, and that escalating interest rates suppress housing finance and limit how far the mortgage market reaches. Exchange-rate risk on external debt was also found to raise construction costs indirectly.3
Evidence-backed: The studies disagree on which lever matters most. In Malaysia, money supply, interest rate and employment were all significant in the short run, but only money supply and the other indicators showed long-run cointegration — interest rate did not — leading the authors to recommend regulating money supply rather than controlling interest rates to promote affordability.4

What it means for homeowners and buyers
AI summary:New borrowing gets costlier while price growth tends to cool, and whether rate policy can fix affordability is disputed.
Interpretation: For anyone borrowing now, the direct effect is on the cost of a new mortgage: the Czech evidence shows policy rates feed through into the rates lenders charge. For existing owners on fixed-rate deals, the material does not measure when or whether their payments change, so that depends on the terms of the individual loan.1
Evidence-backed: For prices, the direction of effect runs the other way. The ten-country panel regression found that, controlling for GDP growth and unemployment, a change in the real interest rate imposed a negative effect on house price growth rates — higher real rates were associated with slower price growth. The Czech analysis also identified episodes of price growth with characteristics consistent with speculative bubbles.21
Evidence-backed: Affordability is not simply the mirror of rates. The cross-country study's practical conclusion is that using monetary policy to solve housing affordability is a mis-prescription because it distorts housing market dynamics. In Malaysia, housing has been seriously unaffordable for a decade, with the median multiple house price above three times median household income, and the authors still found interest rate insignificant in the long run.24
Evidence-backed: The Australian study, covering 1998–2009 across all eight capital cities, concluded that monetary policy played an active role in housing affordability through adjustments to money supply and interest rates, and suggested the results could help decision makers set those variables with affordability in mind.5

- 1Monetary Policy Tools of the Czech National Bank and Their Impact on the Mortgage Market and Housing Affordability in the Czech Republic in 2008–2022Digital Repository (National Repository of Grey Literature) (PavelKoktavý)Published Jan 1, 2026Checked Oct 6, 2026
“This bachelor’s thesis examines how the monetary policy instruments of the Czech National Bank are transmitted to the mortgage market and residential property prices in the Czech Republic over the period 2008–2024. The theoretical section defines monetary policy instruments, policy objectives, and the transmission mechanism, including its specific features within the real estate market. The empirical section employs descriptive analysis, regression models, lag analysis, a VAR model, impulse response functions, Granger causality tests, and the BSADF test to quantify the relationships between the repo rate, mortgage rates, the volume of new mortgage loans, and property prices. The results demonstrate statistically significant transmission linkages between monetary policy and the mortgage market and confirm that changes in the CNB’s interest rates are passed through to mortgage rates as well as to lending activity. The analysis also identifies episodes of price growth that exhibit characteristics consistent with speculative bubbles. The thesis summarizes the effects of transmission channels and discusses factors influencing mortgage accessibility in the Czech Republic.”
- 2Are Central Banks’ Monetary Policies the Future of Housing Affordability SolutionsUrban Science (Yiu)Published Feb 2, 2023Checked Oct 6, 2026
“This cross-country study exploited the two global interest rate shocks as quasi-experiments to test the impacts and causality of monetary policy (taking real interest rates as a proxy) on house prices. Global central banks’ synchronized reduction in interest rates after the outbreak of the COVID-19 pandemic in 2020 and then the global synchronized increase in interest rates after the global inflation crisis in 2022 provided both a treatment and a treatment reversal to test the monetary policy hypothesis. The stylized facts vividly reveal the negative association between interest rate changes and house price changes in many countries. This study further conducted a ten-country panel regression analysis to test the hypothesis. The results confirmed that, after controlling for GDP growth and unemployment factors, the change in real interest rate imposed a negative effect on house price growth rates. The key practical implication of this study pinpoints the mal-prescription of harnessing monetary policy to solve housing affordability issues, as it can distort housing market dynamics.”
- 3The Crowding-Out Effect: Modelling the Impact of Government Borrowing, Inflation & Monetary Policy on Access to Sustainable Finance for Affordable Housing & Social Infrastructure DevelopmentModern Economy (Owotemu & Kale)Published Jan 1, 2025Checked Oct 6, 2026
“Leveraging recent data from authoritative sources such as the Central Bank of Nigeria, the National Bureau of Statistics, and the World Bank, the study employs econometric modelling and descriptive analysis to evaluate these impacts. Key findings indicate that the crowding-out effect of domestic debt is more pronounced due to its direct competition in the local financial market; the escalation of interest rates suppresses housing finance, further limiting the penetration rate of the mortgage market; the exchange rate risk associated with external debt increases construction costs, posing an indirect threat to housing affordability and social infrastructure development, underscoring the critical need for fiscal discipline and innovative solutions like blended and Catalytic funds to improve the delivery of social infrastructure and the housing sector’s resilience. Key recommendations include adopting debt management reforms, promoting specialized housing finance instruments, and fostering public-private partnerships.”
- 4THE IMPACT OF MONETARY POLICY ON HOUSING AFFORDABILITY IN MALAYSIAPLANNING MALAYSIA (Nasir et al.)Published Apr 18, 2022Checked Oct 6, 2026
“In Malaysia, it has been a decade since the median multiple house price reaching more than a tripled median household income threshold in term of housing affordability. This indicates that housing in Malaysia is seriously unaffordable. In general, this study was conducted to examine the impact of monetary policy on housing affordability in Malaysia. This study focuses on investigating both short and long-run relationships between money supply and interest rate on housing affordability. To achieve this goal, Autoregressive Distributed Lag (ARDL) estimation techniques were employed on a quarterly data from the first quarter of 2008 until the first quarter of 2021. The findings showed the existence of long-run cointegration between all indicators except for the interest rate. In addition, money supply, interest rate, and employment were found to be significant in the short run. In the matter of policy implication, it is best for policymakers to focus on regulating money supply rather than controlling interest rate in promoting housing affordability.”
- 5Impacts of Monetary Policies on Housing Affordability in AustraliaFigshare (Liu & Liu)Published Jan 1, 2010Checked Oct 6, 2026
“Housing affordability has become a major policy issue in many countries across the world since the rapid inflation of house prices. This paper empirically investigates how monetary policies affect housing affordability in Australia from 1998 to 2009. Three primary variables associated with the housing sector and monetary policy, which are money supply, interest rates and house prices, are studied for all eight capital cities in Australia in this research. Shocks of such variables are identified by a structural vector autoregression (SVAR) model with restrictions that are consistent with economic theoretical framework. Based upon the analysis using the structural decomposition of impulse response on quarterly data, it can be discovered that the monetary policy plays an active role in housing affordability via adjustments of money supply and interest rates during the observed period in Australia. The empirical results from this research may be used for decision makers to determine money supply and interest rates from the perspective of housing affordability.”
