Convertible or not: making sense of stresses in AT1 bonds market

Mahmoud Fatouh and Ioana Neamțu

Similar to the Deutsche Bank’s episode in 2016 and the Covid stress in 2020, AT1 spreads over subordinated debt rose rapidly and sharply following the Credit Swiss rescue deal. Beyond these three cases, AT1 spreads have been stable. In this post, we focus on conversion risk of AT1 bonds (also known as contingent convertible, CoCo, bonds) to explain the sharp rise in AT1 spreads in these three cases. Conversion risk is the main additional risk of AT1 bonds, compared to subordinated debt. It arises from the potential wealth transfer from AT1 bondholders to existing shareholders when AT1 conversion is triggered, conditional on the solvency of the issuer. We show that, in normal times, investors believe conversion risk is very low, but major events can change this significantly, largely due to higher uncertainty.

Do larger bond trades cost more to execute?

Gábor Pintér

Are larger trades more or less expensive to execute in bond markets than smaller trades? This is an old and unsettled question in the literature on financial markets. The aim of this blog post is to provide novel answers to this question, based on our recent research using transaction-level data from the UK government and corporate bond markets, over the period 2011–17.[1]

Market fragility in the pandemic era

Gerardo Ferrara, Maria Flora and Roberto Renò

Financial markets process orders faster now than ever before. However, they remain prone to occasional dysfunction where prices move away from fundamentals. One important type of market fragility is flash events. Identifying such events is crucial to understanding them and their effects. This post displays the results from a new methodology to identify these, but also longer lasting V-shaped events, as we show here with an application to three sovereign bond markets.

Global real interest rates since 1311: Renaissance roots and rapid reversals

Paul Schmelzing

Paul Schmelzing is a visiting scholar at the Bank from Harvard University, where he concentrates on 20th century financial history. In this guest post, he looks at how global real interest rates have evolved over the past 700 years.

With core inflation rates remaining low in many advanced economies, proponents of the “secular stagnation” narrative –that markets are trapped in a period of permanently lower equilibrium real rates- have recently doubled down on their pessimistic outlook. Building on an earlier post on nominal rates this post takes a much longer-term view on real rates using a dataset going back over the past 7 centuries, and finds evidence that the trend decline in real rates since the 1980s fits into a pattern of a much deeper trend stretching back 5 centuries. Looking at cyclical dynamics, however, the evidence from eight previous “real rate depressions” is that turnarounds from such environments, when they occur, have typically been both quick and sizeable.

Venetians, Volcker and Value-at-Risk: 8 centuries of bond market reversals

Paul Schmelzing, Harvard University.

Paul Schmelzing is a visiting scholar at the Bank from Harvard University, where he concentrates on 20th century financial history. In this guest post, he looks at the current bond market through the lens of nearly 800 years of economic history.

The economist Eugen von Böhm-Bawerk once opined that “the cultural level of a nation is mirrored by its interest rate: the higher a people’s intelligence and moral strength, the lower the rate of interest”. But as rates reached their lowest level ever in 2016, investors rather worried about the “biggest bond market bubble in history” coming to a violent end. The sharp sell-off in global bonds following the US election seems to confirm their fears. Looking back over eight centuries of data, I find that the 2016 bull market was indeed one of the largest ever recorded. History suggests this reversal will be driven by inflation fundamentals, and leave investors worse off than the 1994 “bond massacre”.
