Bitesize: The rise and fall of interest only mortgages

Sachin Galaiya

The interest-only product has undergone tremendous evolution, from its mass-market glory days in the run-up to the crisis, to its rebirth as a niche product. However, since reaching a low-point in 2016, the interest-only market is starting to show signs of life again as lenders re-enter the market.

The Spanish Connection – Consequences of a macroprudential regulation in Spain on Mexico

Jagdish Tripathy

Does macroprudential regulation spillover to foreign financial systems through inter-bank linkages? This question has received a lot of attention in recent years given the discord between the international nature of the global financial system and its regulation and supervision by national jurisdictions (e.g. this article). For example, subsidiaries of Spanish banks issue almost half of all credit issued by commercial banks in Mexico. These subsidiaries are also fully owned by their parent banks headquartered in Spain. Therefore, it is quite natural to ask whether macroprudential regulations in Spain can have unintended consequences on the Mexican financial system and the Mexican economy in general. While Mexican subsidiaries of Spanish banks are de-jure ring-fenced from regulations in Spain, does this hold de-facto?

Completing Correlation Matrices

Dan Georgescu and Nicholas J. Higham

Correlation matrices arise in many applications to model the dependence between variables. Where there is incomplete or missing information for the variables, this may lead to missing values in the correlation matrix itself, and the problem of how to complete the matrix. We show that some of these practical problems can be solved explicitly, via simple formulae, and we explain how to use mathematical tools to solve the more general problem where explicit solutions may not exist. “Simple” is, of course, a relative term, and the underlying matrix algebra and optimization necessarily makes this article more mathematically sophisticated than the typical Bank Underground post.

Population ageing and the macroeconomy

Noëmie Lisack, Rana Sajedi and Gregory Thwaites

An unprecedented ageing process is unfolding in industrialised economies. The share of the population over 65 has gone from 8% in 1950 to almost 20% in 2015, and is projected to keep rising. What are the macroeconomic implications of this change? What should we expect in the coming years? In a recent staff working paper, we link population ageing to several key economic trends over the last half century: the decline in real interest rates, the rise in house prices and household debt, and the pattern of foreign asset holdings among advanced economies. The effects of demographic change are not expected to reverse so long as longevity, and in particular the average time spent in retirement, remains high.

Trimming the Hedge: How can CCPs efficiently manage a default?

Fernando Cerezetti, Emmanouil Karimalis, Ujwal Shreyas and Anannit Sumawong

When a trade is executed and cleared though a central counterparty (CCP), the CCP legally becomes a buyer for every seller and a seller for every buyer. When a CCP member defaults, the need to establish a matched book for cleared positions means the defaulter’s portfolio needs to be closed out. The CCP then faces a central question: what hedges should be executed before the portfolio is liquidated so as to minimize the costs of closeout?  In a recent paper, we investigate how distinct hedging strategies may expose a CCP to different sets of risks and costs during the closeout period. Our analysis suggests that CCPs should carefully take into account these strategies when designing their default management processes.

Stirred, not shaken: how market interest rates have been reacting to economic data surprises

Jeremy Franklin, Scott Woldum, Oliver Wood and Alex Parsons

How do markets react to the release of economic data? We use a set of machine learning and statistical algorithms to try to find out.  In the period since the EU referendum, we find that UK data outturns have generally been more positive than market expectations immediately prior to their release. At the same time, the responsiveness of market interest rates to those data surprises fell below historic averages.  The sensitivity of market rates has also been below historic averages in the US and Euro area, suggesting international factors may also have played a role. But there are some signs that the sensitivity has increased over the past year in the UK.

Is a steeper yield curve good news for banks? A challenge to the conventional wisdom

Oliver Brenman, Frank Eich, and Jumana Saleheen

The conventional wisdom amongst financial market observers, academics, and journalists is that a steeper yield curve should be good news for bank profitability.   The argument goes that because banks borrow short and lend long, a steeper yield curve would raise the wedge between rates paid on liabilities and received on assets – the so-called “net interest margin” (or NIM).  In this post, we present cross-country evidence that challenges this view.  Our results suggest that it is the level of long-term interest rates, rather than the slope of the yield curve, that drives banks’ NIMs.

Bitesize: Financial services exports and financial openness: two sides of the same coin

Carlos Eduardo van Hombeeck

The UK has a comparative advantage in financial services. But specialisation in this activity brings with it the challenge of the large gross capital flows that are linked to financial services exports.

Voting with their wallets? Consumer expectations after the EU referendum

Tamara Li, Nicola Shadbolt, Thomas Stratton and Gregory Thwaites

Consumption growth remained fairly steady in the immediate aftermath of the UK vote to leave the European Union in June 2016. But how did consumer expectations evolve in the first months after the referendum? We show with the Bank’s in-house household survey that ‘Leavers’ became more positive about the economy and their own financial situation after the referendum, with the opposite true for ‘Remainers’, and that this was reflected in spending by the two groups. But the size of the effect was small.

Who’s driving consumer credit growth?

Ben Guttman-Kenney, Liam Kirwin, Sagar Shah

Consumer credit growth has raised concern in some quarters. This type of borrowing – which covers mainstream products such as credit cards, motor finance, personal loans and less mainstream ones such as rent-to-own agreements – has been growing at a rapid 10% a year. What’s been driving this credit growth, and how worried should policymakers be?
