Distributional consequences of borrower-based macroprudential tools

Jagdish Tripathy, Arzu Uluc, José-Luis Peydró and Francesc Rodriguez-Tous

Borrower-based macroprudential measures – such as limits on loan to income (LTI) and loan to value (LTV) ratios – have become a standard feature of the post-crisis regulatory landscape. A growing body of country-specific evidence suggests these measures are effective in moderating the self-reinforcing loop between mortgage credit and house prices, and in reducing default rates and limiting house price volatility during periods of economic stress. Yet their distributional consequences are less well understood. In a new paper, we survey the existing evidence and find that these tools deliver clear financial stability benefits, while also generating distributional effects across borrower groups. Further, we identify areas where future research is needed to provide a comprehensive welfare assessment of these measures.

Why do government bond yields drift when news is on its way?

Danny Walker, Dong Lou, Gabor Pinter and Semih Üslü

Government bond yields tend to drift higher in the days before monetary policy or data news in the UK. Over the past two decades this tendency – which we label ‘pre-news drift’ – has pushed up on yields by 2 percentage points in total over that period. The drift concentrates in pre-news periods that coincide with the issuance of UK government bonds, which is more common than it used to be. Our analysis shows that dealers and hedge funds are reluctant to buy bonds when news is on its way, which pushes up yields. Pre-news drift could affect the signal monetary policy makers draw from market rates and it could have implications for the optimal timing of bond issuance. There are further details in an associated working paper.

What caused the LDI crisis?

Gabor Pinter, Emil Siriwardane and Danny Walker

In September 2022 the interest rate on UK gilts rose by over 100 basis points in four days. These unprecedent market movements are generally attributed to two key factors: the 23 September announcement of expansionary fiscal policy – the so-called ‘mini-budget’ – which was then amplified by forced sales by liability-driven investment funds (LDI funds). We estimate that LDI selling accounted for half of the decline in gilt prices during this period, with fiscal policy likely accounting for the other half. Balance sheet segmentation and operational issues slowed capital injections into LDI funds by well-capitalised pension schemes, leading LDI funds to instead sell gilts. Our analysis shows that these frictions were most pronounced for pooled LDI funds. There are further details in an associated working paper.

Beyond emissions: the interplay of macroprudential regulation and climate policy

Francesca Diluiso, Barbara Annicchiarico and Marco Carli

While climate change is often seen as a long-term concern, climate mitigation policies can have different short-term effects, since they affect the transmission mechanism of conventional macroeconomic shocks. In a new working paper, we show that cap-and-trade schemes lead to lower volatility in GDP and financial variables, and result in reduced welfare costs of the business cycle, when compared to the more widely known carbon taxes. As we find that these welfare differences are primarily driven by distortions in financial markets, we argue that countercyclical macroprudential regulation, even without any green-biased component, can effectively align the welfare performance of these policies and mitigate their short-run costs.

The transmission of macroprudential policy in the tails

Álvaro Fernández-Gallardo, Simon Lloyd and Ed Manuel

Since the 2007–09 Global Financial Crisis, central banks have developed a range of macroprudential policies (‘macropru’) to address fault lines in the financial system. A key aim of macropru is to reduce ‘left-tail risks‘ – ie, minimise the probability and severity of future economic crises. However, building this resilience could influence other parts of the GDP-growth distribution and so may not always be costless. In our Working Paper, we gauge these potential costs and benefits by estimating the effects of macropru on the entire GDP-growth distribution, and explore its transmission channels. We find that macropru is effective at reducing the variance of GDP growth, and that it does so by reducing the probability and severity of excessive credit booms.

Funding structures and resilience to shocks after a decade of regulatory reform

Kristin Forbes, Christian Friedrich and Dennis Reinhardt

Recent episodes of financial stress, including the ‘dash for cash’ at the onset of the Covid-19 (Covid) pandemic, pressure in the UK’s liability-driven investment funds in 2022, and the collapse of Silicon Valley Bank in 2023, were stark reminders of the vulnerability of financial institutions to shocks that disrupt liquidity and access to funding. This post explores how the funding choices of banking systems and corporates affected their resilience during the early stages of Covid and whether subsequent policy actions were effective at mitigating financial stress. The results suggest that policy responses targeting specific structural vulnerabilities were successful at reducing financial stress.

Strengthening the resilience of market-based finance

Naoto Takemoto, Simon Jurkatis and Nicholas Vause

In less than two decades, the system of market-based finance (MBF) – which involves mainly non-bank financial institutions (NBFIs) providing credit to the economy through bonds rather than loans – has both mitigated and amplified the economic effects of financial crises. It mitigated effects after the global financial crisis (GFC), when it substituted for banks in providing credit. But it amplified effects at the outbreak of the Covid pandemic, when NBFIs propagated a dash for cash (DFC), and more recently when pension fund gilt sales exacerbated increases in yields. This post outlines five different aspects of MBF that contribute to such amplification and summarises some policy proposals – suggested and debated internationally by regulators, academics and market participants – to make MBF more resilient.

Swing or amiss: are fund pricing rules good for financial stability?

Benjamin King and Jamie Semark

Open-ended funds (OEFs) offer daily redemptions to investors, often while holding illiquid assets that take longer to sell. There is evidence that this mismatch creates an incentive for investors to redeem ahead of others, which could lead to large redemptions from OEFs and asset price falls. Some research has suggested that ‘swing pricing’ can help to moderate these redemptions, but until now, no-one has considered the impact of its use on the wider economy. In a recent paper, we carry out a financial stability cost-benefit analysis of more widespread and consistent usage of swing pricing by OEFs, finding that enhanced swing pricing could reduce amplification of shocks to corporate bond prices, providing benefits to the financial system and economy.

Back to the Future IV: challenges for financial stability policy in the next decade

Alina Barnett, Sinem Hacioglu Hoke and Simon Lloyd

Since 2007, macroprudential policymakers have grappled with a broad set of vulnerabilities. While regulators cannot be sure what risks the next decade will feature, they can be sure that the set of issues will continuously evolve. In this post, we explore three timely challenges that financial stability policymakers are likely to face in the coming years, including risks associated with: non-bank financial intermediation, cryptoassets and decentralised finance (DeFi), and climate change. These challenges have been noted by many, and are already stimulating development of macroprudential frameworks. But while some of this development can build on well-grounded principles for financial stability policy, other aspects are likely to come up against three timeless challenges, requiring novel and innovative thinking to overcome.

Debt and investment: what can we learn from SMEs’ investment behaviour during and after the Global Financial Crisis?

Mai Daher and Christiane Kneer

Many UK firms weathered the Covid shock by taking on debt. Small and medium-sized enterprises (SMEs) in particular borrowed at an unprecedented rate and their debt increased by around a quarter since end-2019. But debt that allowed SMEs to survive the pandemic could now hamper the recovery as indebted firms may struggle to invest and grow. Debt on SMEs’ balance sheets could also make firms more vulnerable to future shocks and could amplify downturns if indebted firms reduce investment more following shocks. To understand how investment might evolve, our recent FS paper examines how leverage affected SME investment during and after the Global Financial Crisis (GFC) and discusses potential differences given regulatory and other changes since the GFC.
