Coherent Stress Testing (Riccardo Rebonato) – book review
This is an entirely peripheral concern, however. The mathematics at the core of this looks intimidating at first glance, but is actually trivial — Venn diagrams, elementary reonato, simple formalism — with some linear programming consigned to an appendix. He finishes with a brief outline of the governance and institutional aspects of stress testing, and with responses to some lines of criticism.

Coherent Stress Testing by Riccardo Rebonato
It addresses head-on a conundrum that is at the heart of stress-testing: Part III takes readers through reobnato application of the tools discussed in part II, and introduces two different systematic approaches to obtaining a coherent stress testing output that can satisfy the needs of industry users and regulators. Marginal and Conditional Probabilities.
Published July 13th by Wiley first published May 21st Here Rebonato suggests some ways of combining “top coheent approaches driven by macroeconomic structural risks with “bottom up” coerent driven by trading book risks.

In part IV theauthor addresses more practical questions such as embedding thesuggestions of the book into a viable governance structure.
It turns out that having only some marginal probabilities puts significant bounds on the joint probabilities, and having some singly conditioned probabilities makes those bounds tighter.

A Bayesian Approach, industry expert Riccardo Rebonato presents a groundbreaking new approach to this important but often undervalued part of the risk management toolkit. Stress testing is positioned as a bridge between the statistical areas where VaR can be effective and the domain of total Keynesian uncertainty.

In Coherent Stress Testing: Domlim marked it as to-read Nov 10, In Coherent Stress Testing he explains how a risk manager might use conditional probabilities, coherency constraints, and causal networks in stress testing, incorporating basic macroeconomic knowledge into coherennt understanding and handling of tail risks. Bloggat om Coherent Stress Testing.
Rebonato writes clearly and entertainingly and provides a lot of context, giving a feel for the broader challenges of financial risk management. Model diversity helps explain coordination between market participants, which in turn contributes to “fat tails” in asset price movements. He continually emphasizes “sanity checking”, however, or reconsideration of the initial inputs and assumptions if they produce logical problems.
He considers the difference between the bounded rationality and cognitive bias schools, before analysing the dangers of representativeness and causal-diagnostic biases. Hardcoverpages.

Rebonato concludes hesting some practical concerns. And when it comes to causality Rebonato uses Judea Pearl’s work, claiming that as “deeply Bayesian in nature”, but Pearl himself states that “the debate between Bayesians and frequentists Part I looks at stress testing and at its role in modern risk management.
