The impact of Brexit-related shocks on global asset prices

Marek Raczko, Mo Wazzi and Wen Yan

Economists view the United Kingdom as a small-open economy. In economists’ jargon it means that the UK is susceptible to foreign shocks, but that UK shocks do not influence other countries. This definitely was not the case in 2016. The result of the EU referendum, even though it was a UK-specific policy event, had a global impact. Our analysis shows that the Brexit vote not only had a significant impact on UK bond and equity markets, but also spilled over significantly to other advanced economies. Moreover, this approach suggests that the initial Brexit-shock has only partially reversed and still remains a drag on global bond yields and equity prices, though there are wide error bands around that conclusion.

Big Data jigsaws for Central Banks – the impact of the Swiss franc de-pegging

Olga Cielinska, Andreas Joseph, Ujwal Shreyas, John Tanner and Michalis Vasios

The Bank of England has now access to transaction-level data in over-the-counter derivatives (OTCD) markets which have been identified to lie at the centre of the Global Financial Crisis (GFC) 2007-2009. With tens of millions of daily transactions, these data catapult central banks and regulators into the realm of big data.  In our recent Financial Stability Paper, we investigate the impact of the de-pegging in the euro-Swiss franc (EURCHF) market by the Swiss National Bank (SNB) in the morning of 15 January 2015. We reconstruct detailed trading and exposure networks between counterparties and show how these can be used to understand unprecedented intraday price movements, changing liquidity conditions and increased levels of market fragmentation over a longer period.

An intuitive interpretation of factor models

Sinem Hacioglu Hoke and Kerem Tuzcuoglu

We economists want to have our cake and eat it. We have far more data series at our disposal now than ever before. But using all of them in regressions would lead to wild “over-fitting” – finding random correlations in the data rather than explaining the true underlying relationships. Researchers using large data sets have historically experienced this dilemma – you can either throw away some of the information and retain clean, interpretable models; or keep most of the information but lose interpretability. This trade-off is particularly frustrating in a policy environment where understanding the identified relationships is crucial. However, in a recent working paper we show how to sidestep this trade-off by estimating a factor model with intuitive results.

What happened to competition between UK deposit takers over the past 25 years?

Sebastian J A de-Ramon and Michael Straughan.

The landscape for competition between UK deposit takers (retail banks and building societies) was reset in the 1980s with the removal of the bank “corset” (1981), the Big Bang reforms and the Building Societies Act (both in 1986). These reforms facilitated entry and expansion of different business models into markets that had previously been off-limits. What followed was a significant restructuring of the deposit taking sector in the UK. In a new paper, we show that competition between UK deposit takers weakened substantially in the years leading up to the financial crisis.

Low for long: what does this mean for defined-benefit pensions in the UK?

Frank Eich and Jumana Saleheen.

Despite the fact that the financial crisis erupted nearly a decade ago, its legacy is still being felt today.  Disappointingly weak growth and low interest rates are arguably part of that legacy (though other developments also matter), and policy makers are increasingly worried that these are no longer temporary phenomena but instead have become permanent features.  This blog assesses what a prolonged period of weak growth and low interest rates (sometimes also referred to by “secular stagnation” or “low for long”) might mean for the viability of defined-benefit (DB) occupational pension schemes in the UK and what financial stability risks might arise as a result of a changing business environment.

Mind over matter: is scarcity as much about psychology as it is economics?

Dan Nixon.

“Unlimited wants, scarce resources”. This is the economic problem.  But once basic needs are met, how much should scarcity – having “enough” – be understood as a psychological problem? Is it possible to cultivate an “abundance mindset”? And what does all of this mean for how economics is taught?

The U Word: What can text analytics tell us about how far uncertainty has risen during 2016?

Alastair Cunningham, David Bradnum and Alastair Firrell.

Uncertainty is a hot topic for economists at the moment.  Have business leaders become more uncertain as a result of the EU referendum?  If so, has that uncertainty had any effect on their plans?   The Bank’s analysts look at lots of measures of economic uncertainty, from complex financial market metrics to how often newspaper articles mention it.  But few of those measures are sourced directly from the trading businesses up and down the country whose investment and employment plans affect the UK economy.  This blog reports on recent efforts to draw out what the Bank’s wide network of business contacts are telling us about uncertainty – comparing what we’re hearing now to trends seen in recent years.

Home is where your cash flows are? UK-focused equities and the international exposure of the FTSE All-Share

Lu Liu.

Equity prices reflect the market value of public companies, making them an important indicator of the economy.  In practice, stocks by firms listed on the local stock exchange serve as the ‘domestic’ equity benchmark but this might be misleading as an indicator of the national economy:  stock markets track the performance of individual firms, including their international business.  This makes it particularly challenging to extract a signal for the UK economy from UK equity prices, as the universe of UK-listed firms tends to be very global – for instance, around 2/3 of sales represented on the FTSE All-Share are generated abroad.  So for a better read of the UK economy, I’ll look at a subset of more UK-focused stocks and other more domestically-focused UK equity indices.

There are two productivity puzzles

Patrick Schneider.

Much has been written about the productivity puzzle. But there are actually two puzzles apparent in the data – one in the level that hit at the crisis and the other in the growth rate, which is a more recent phenomenon – and they could be driven by completely different sources. Distinguishing between the two puzzles is important precisely because of these potential differences – if anyone analyses the puzzle as a whole looking for the force driving it, the actual underlying variety will confound our estimates of the relative importance of these drivers.

In this post I discuss:

  1. what people mean by the productivity puzzle, usually a percent deviation from the pre-crisis trend;
  2. how I think of it as actually two puzzles: one in the level and the other in the growth rate; and
  3. why this distinction can be important, using the example of a simple growth accounting decomposition of productivity growth into capital deepening and technological advancement.
