Central banks raised interest rates aggressively beginning in 2022 to combat inflation. Mortgage rates doubled or tripled in many OECD countries. The housing market was supposed to cool. Prices did slowโ€”but affordability did not improve. The reason is structural: housing affordability is a function of prices, incomes, and borrowing costs. When interest rates rise, monthly payments increase even if prices stagnate. The result is a paradox: the policy intended to reduce inflation may have made the housing crisis worse for prospective buyers.

The Research Landscape

The Rate-Affordability Paradox

Sanchez-Moyano (2025), publishing with the Federal Reserve Bank of San Francisco provides the most directly relevant analysis. Using 2023 data on the US homebuying landscape, the study documents how the combined effect of price increases and interest rate hikes challenged homebuying affordability. The years following the pandemic saw a sharp contraction in market activity as affordability deteriorated. Critically, the author shows that while transaction volumes fell, prices did not fall proportionallyโ€”creating a "frozen market" where existing homeowners refused to sell (locking in their low-rate mortgages) and new buyers could not afford to enter.

Pechalova (2025) examines housing market imbalance and systemic risk from a regulatory perspective. The analysis identifies a persistent gap between primary and secondary housing markets: new construction prices reflect current input costs and financing conditions, while existing homes are anchored to purchase-price expectations. This bifurcation creates market dysfunctionโ€”neither segment clears efficiently, and the aggregate effect is reduced housing mobility.

Supply Constraints Compound Rate Effects

Chapple and Song (2024), publishing in the Journal of the American Planning Association provide rigorous evidence on housing supply dynamics in Los Angeles and San Francisco. Their unique database on construction and household mobility reveals that new market-rate housing generally helps alleviate displacement and exclusion pressures for low-income householdsโ€”but particularly in the hottest markets, new units can fail to spur low- and moderate-income in-migration. The finding is important because it demonstrates that supply-side interventions interact with demand-side conditions: building more housing helps, but not enough in high-cost markets where interest rates have priced out the target population.

Breach (2025), analyzing England's planning system, makes a strong structural argument: the discretionary planning system introduced in 1947 sharply curtailed housebuilding, particularly in cities. The long-term effect is chronic undersupply that interest rate movements cannot remedy. When rates were low, prices surged because supply could not respond. When rates rose, prices stabilized but affordability worsened because borrowing costs increased. The supply constraint makes housing affordability pro-cyclical in a way that monetary policy cannot offset.

Policy Responses Under Strain

Koszel, Mazurczak, and Strฤ…czkowski (2025) evaluate the effects of government housing programs in Poland from 2008 to 2023, finding that demand-side subsidies in the context of high interest rates and constrained supply led to dynamic price increases rather than improved affordability. The pattern is familiar: government programs that subsidize demand without addressing supply merely shift the price distribution upward.

Jazuli, Rahman, and Naharu (2026) provide a bibliometric review mapping the global housing affordability crisis. Their analysis identifies a consistent finding: housing affordability is a multi-causal problem where monetary policy, land use regulation, construction costs, and financialization interact. No single policy lever is sufficient.

The Lock-In Trap

The "lock-in effect" deserves special attention because it is a novel market dysfunction created by the rapid transition from ultra-low to high interest rates. In the United States, approximately 90% of existing mortgages carry rates below the current market rate. Homeowners who would normally sell and buy a new homeโ€”creating supply for other buyersโ€”are rationally choosing to stay. This reduces inventory, maintains price floors, and transfers the affordability burden entirely to first-time buyers and renters.

The lock-in effect creates a distributional problem: existing homeowners are sheltered from rate increases while prospective buyers bear the full costโ€”a wealth transfer from young to old, from renters to owners, precisely the opposite of what housing policy aims to achieve.

Open Questions and Future Directions

  • Rate normalization timing: If and when central banks reduce rates, will affordability improve? The lock-in effect suggests that rate cuts will release pent-up demand, potentially pushing prices higher and offsetting the borrowing cost reduction.
  • Institutional ownership: The growing share of housing owned by institutional investors (REITs, private equity) introduces a new demand source with different price sensitivity than individual buyers. How does institutional ownership interact with interest rate effects?
  • Remote work and spatial reallocation: The pandemic enabled geographic mobility for knowledge workers. Has this permanently changed housing demand patterns, or will urban premium reassert itself?
  • Construction cost inflation: Material and labor costs for new construction have risen substantially. Even with permissive zoning, can new supply be delivered at prices affordable to median-income households?
  • Intergenerational equity: If the current generation of first-time buyers is permanently locked out, what are the long-run consequences for wealth accumulation, family formation, and social mobility?
  • What This Means for Your Research

    The housing affordability crisis is not a cyclical problem that monetary policy normalization will resolve. It is a structural condition rooted in chronic undersupply, planning restrictions, financialization, and income stagnation. Interest rate movements exacerbate or ameliorate the symptoms but do not address the causes. Researchers should be cautious about studies that isolate monetary policy effects without accounting for supply constraints, regulatory environments, and distributional consequences.
