Is the tail wagging the dog? The impact of VIX exchange traded products on equity volatility

Olga Maizels

Volatility returned to markets in early February, sparked by strong US wage growth data.  After  months of calm, the S&P 500 equity index fell by 4% on 5 February and the VIX – a measure of US equity volatility that is sometimes referred to as Wall Street’s “fear gauge” – experienced its largest one-day move in its 28-year history.  Interestingly, measures of volatility in other markets, including interest rates and currencies, moved by much less.  So what caused the outsized spike in the VIX?  Some of the rise was linked to rebalancing flows associated with VIX exchange-traded products (ETPs), which can amplify moves in the volatility market.  The events have also led to some questions whether developments in VIX ETPs can also affect the S&P 500 itself –whether the ‘tail’ can wag the ‘dog’.

UK trade: going steady since the 1960s

Countries’ goods exports are normally defined in terms of what has been shipped when and where. Recent literature (e.g. Besedeš and Prusa, 2011 and Besedeš et al, 2016) shows that looking at how long trade relationships have been in place is important as well. Using highly granular data, we show that over 60% of the value of UK nominal goods exports is in very mature trading relationships, by which we mean exports of a particular product between a pair of countries in a given year. This is true even with substantial churn (new relationships starting and old ones ceasing) going on all the while, and for exports in real terms as well.

What can regional data tell us about the UK Phillips Curve?

Alex Tuckett

The Phillips Curve (PC) is an old concept in economics, but it is a durable one. The simple idea behind the PC is that the lower the rate of unemployment, the faster wages will grow. If the PC has changed over time, that can have important implications for monetary policymakers. Analysis of regional UK data suggests that the PC has shifted down over time, but has not necessarily become flatter. Higher levels of educational attainment are likely to have contributed to this shift.

What did the CBPS do to corporate bond yields?

Calebe de Roure, Ben Morley and Lena Boneva

In August 2016 the MPC announced a package of easing measures, including the Corporate Bond Purchase Scheme (CBPS). In a recent staff working paper, we explore the announcement impact of the CBPS, using the so called “difference in differences” (or “DID”) approach. Overall – to deliver the punchline to eager readers – this analytical technique suggests that the announcement caused spreads on CBPS eligible bonds to tighten by 13bps, compared with comparable euro or dollar denominated bonds (Charts 1b, 2).
