Mortgage affordability for borrowers who re-fixed in 2023

Daniel Norris, Elio Cucullo and Vasilis Jacovides

When borrowers enter a fixed-rate mortgage, lenders test whether they could continue to afford their mortgage if interest rates were to increase by the time it comes to re-fix. This ‘stressing’ is designed to create additional resilience for borrowers and the financial system. Over the last two years, mortgage rates have increased by over four percentage points, raising the cost of repayments for those re-fixing. We look at UK mortgage data and compare the stress rates applied at origination to rates available to borrowers when re-fixing. We find that the vast majority of borrowers who came to the end of their fixed terms in 2023 faced new mortgage rates which were lower than those they had been ‘stressed’ at.

The macroprudential toolkit: effectiveness and interactions

Stephen Millard, Margarita Rubio and Alexandra Varadi

The 2008 global financial crisis showed the need for effective macroprudential policy. But what tools should macroprudential policy makers use and how effective are they? We examined these questions in in a recent staff working paper. We introduced different macroprudential tools into a dynamic stochastic general equilibrium (DSGE) model of the UK economy and compared their impact on the economy and household welfare, as well as their interaction with each other and with monetary policy. We found that capital requirements reduce the effects of financial shocks. Instead, a limit on how much of borrowers’ income is spent on mortgage interest payments reduces the volatility of lending, output and inflation resulting from housing market shocks.

Housing consumption and investment: evidence from the Help to Buy scheme

Matteo Benetton, Philippe Bracke, João F Cocco and Nicola Garbarino

Academics have made the case for mortgage products with equity features, so that gains and losses due to fluctuations in house values are shared between the household and an outside investor. In theory, the equity component expands the set of affordable properties, without increasing household debt, and default risk. These products have not become mainstream, but in a recent paper, we study a large UK experiment with equity-based housing finance — the Help To Buy Equity Loan scheme. We find that equity loans are mainly used to overcome credit constraints, rather than to reduce investment risk. Unconstrained household prefer mortgage debt over equity loans, suggesting optimism about house price risk. Equity loans could still contribute to house price inflation: we don’t find evidence that houses purchased with equity loans are overpriced, but an assessment of the aggregate effects is beyond the scope of the paper.
