OxTalks is Changing
On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Higher-order Exposures
This seminar will be conducted through Zoom. Please register to join this seminar. You will then receive an email with the dial in details. Please check your spam/junk folders.
Registration: us02web.zoom.us/meetin…
The meeting is set up so that you will join muted and without video. There will be time at the end for a Q&A session. Please use the ‘raise your hand’ function and the presenter will call on you to unmute yourself. A video on how to do this is here.
With the speakers permission, we will be recording this event. We will make these talks available upon request via a password protected/time sensitive link. To request a copy of the recording please email events@inet.ox.ac.uk.
ABSTRACT:
Traditional exposure measures focus on direct exposures to evaluate the losses an institution is exposed to upon the default of a counterparty. Since the Global Financial Crisis of ’07/‘08, indirect exposures via common asset holdings are increasingly recognized too. Yet direct and indirect exposures fail to capture the losses that result from shock propagation and amplification following the counterparty’s default. In this paper, we introduce the concept ``higher-order exposures’‘ to refer to these spill-over losses and propose a way to formalize and quantify them. Using granular data of the South African financial system and a contagion model that captures the most commonly studied contagion channels and their interactions, we show that higher-order exposures make up a significant part of exposures – particularly during times of financial distress when exposures matter most. We also show that higher-order exposures cannot simply be extrapolated from direct or indirect exposures, since they depend strongly on the network structure and the robustness of individual institutions. Our findings suggest that higher-order exposures should inform the design and calibration of those tools in the regulators’ arsenal where exposures matter — including large exposure limits, capital requirement calibration, stress test design and resolution. Failure to do so may result in both lax ex-ante regulation and ill-informed ex-post handling of financial crises.
