Stable gilts and stable prices: assessing the Bank of England’s response to the LDI crisis

Nicolò Bandera and Jacob Stevens

How should the central bank conduct asset purchases to restore market functioning without causing higher inflation? The Bank of England was faced with this question during the 2022 gilt crisis, when it undertook gilt purchases on financial stability grounds while inflation was above 10%. These financial stability asset purchases could have counteracted the monetary policy stance by easing financial conditions at a time when monetary policy was tightening them. Did a trade-off between price and financial stability arise? In our Staff Working Paper, we find the asset purchases stabilised gilt markets without materially affecting the monetary policy stance. This was only possible because the intervention was temporary; highly persistent asset purchases would have created tension between price and financial stability.

Zero-day options and financial market vulnerability

Bowen Xiao

Zero-day options have exploded in popularity in recent years, accounting for approximately half of S&P 500’s total options volume, a ten-fold increase from just 5% in 2016. Their flexibility, low premia and underlying leverage appeal to all market participants ranging from conservative investors hedging against intraday market volatility to aggressive traders speculating for quick profit generation. The rapid rise of zero-day options and the memory of a market stress episode known as ‘Volmageddon‘ raises concerns that zero-day options could lead to a similar event. There are differing views among participants on the perceived risks of zero-day options. This post aims to provide a balanced overview.

Adaptation is to mitigation what Robin is to Batman

Jenny Clark and Theresa Löber

The UK’s climate continues to change, getting wetter and warmer, with extremes becoming ever more pronounced. Even if we limit global warming to 1.5°C above pre-industrial levels, experts warn that we’ll see the number and severity of extreme weather events increase further. Without adaptation, we will see more property, infrastructure and agriculture damaged or destroyed, with devastating consequences to households, communities and businesses – as well as increasing risks to economic and financial stability. To date there has been relatively more focus on mitigation and the transition to net zero than on adaptation and addressing physical risk, across both government and the private sector. Adaptation is mitigation’s sidekick, we need them to consistently work together to achieve better outcomes. Much like Batman and Robin.

Weathering the storm: the economic impact of floods and the role of adaptation

Rebecca Mari and Matteo Ficarra.

Floods are the most costly natural disaster in Europe. In the UK, they account for around GBP1.4 billion in annual losses. Yet, evidence on the macroeconomic implications is inconclusive. GDP often shows a puzzling delayed response, and prices can be pushed in opposite directions. Using a novel county level data set for England for the years 1998–2021, we estimate the impact of flooding on output and inflation at the sector level. Sectors react heterogeneously to floods, which explains well aggregate evidence. Prices respond in sectors related to both headline and core inflation, which has crucial implications for monetary policy. We further show that investing in flood defences mitigates the economic burden of floods by strongly reducing the risk of flooding.

30+ year mortgages – are these the new norm? What does this mean for financial stability?

James Waddell and Meghna Shrestha

An increasing number of households in the UK are opting for longer-term mortgages, with the share of borrowers taking out new mortgages with terms 30 years or longer tripling since 2005. But who are these households, why have they done so, and what could this imply for financial stability?

This blog presents some analysis to answer these questions, and focuses on three potential risk channels which could affect financial stability. These can be broadly classified into: (i) lending into old age; (ii) increased leverage; and (iii) higher debt persistence. We judge the risks associated with longer-term mortgages are limited and are mitigated by existing Financial Policy Committee (FPC) and Financial Conduct Authority (FCA) policies, which limit risky lending both at the borrower level and in aggregate.

Long-term fixed-rate mortgages through an international lens: could they lead to higher home ownership?

Gabija Zemaityte

The Tony Blair Institute for Global Change, among others, has argued that long-term fixed-rate mortgages (LTFRMs) could increase home ownership in the UK. The share of mortgages with longer fixes increased in the UK and internationally over the last decade. Persistently low interest rates over that period have supported demand for longer-fix products, including five-year fixes. But differences in mortgage markets structures across countries are the main drivers of the prevalence of LTFRMs – here defined as mortgages with interest rates fixed for 10 years or more. In this post, I review the international experience, and argue that while LTFRMs can guard against interest rate risk, they do not necessarily increase home ownership. Indeed, some economies with high shares of LTFRMs exhibit lower home ownership.

Sharing interest rate risk: who is trading and what affects the costs?

Ioana Neamțu, Umang Khetan, Jian Li and Ishita Sen

What do the 2023 Silicon Valley Bank collapse and the 2022 UK pension fund crisis have in common? Interest rate risk. Several sectors in the economy run significant asset-liability mismatch that makes them vulnerable to rapid interest rate changes: pension funds and insurers have short-term cash flows and long-term liabilities, while banks follow a lend-long-borrow-short approach. While interest rate derivatives enable risk transfers to hedge these exposures, research on this market is limited, leaving important questions on the extent of risk sharing and the consequences of imbalances unanswered. We construct the largest data set on interest rate swaps using confidential Bank of England data to unlock insights into how investors use these instruments, and their relative importance in determining swap prices.

Shining a light on private equity backed corporates in four findings

Neha Bora, Sarah Burkinshaw, Alice Crundwell and Tuli Saha

Private equity (PE) has rapidly become an important source of financing for UK businesses. Funds use pools of capital, largely from institutional investors, to primarily invest in non-publicly traded companies. We shed light on this growing sector with a new and novel data set of around 9,000 privately backed corporates in the UK. These corporates employ over two million people, with business activity concentrated in London and in certain sectors such as information and communications. We find that they are relatively more vulnerable to default than all other corporates, and they are financed with relatively larger proportions of shorter tenor debt, like private credit and leveraged loans.
