Long-Term Asset Return Study: The Next Financial Crisis
It's almost impossible to have a one size fits all definition of a financial crisis,
especially as there is no set definition. Our analysis might pick up severe
market turbulence rather than a well defined textbook crisis but the reality is
that as long as it's consistent over time the results through history should be
comparable and give us a quantifiable indicator of periods of notably unstable
(and negative) financial markets. We will call our analysis financial shocks to
avoid confusion.
Our 'financial shock' index is calculated based on the proportion of countries
experiencing one of the above conditions in any rolling 12-month period. Given
this definition, our indicator for each country is a binary variable that takes on a
value of 1 if the country experiences a financial shock and 0 otherwise.
Thereafter we aggregate this measure in 2 ways. Our Ira ~SUM is an equally,
weighted measure that counts the number of countries suffering from a financial
shock in a given month and divides it by the number of countries for which we
have data available in that same month (hence each country has an equal
weight in the aggregate measure), to get the percentage of countries (for which
we have data) which are suffering. Our second measure is a GDP weighted
measure that uses the sum of each country's indicator (0 or 1) weighted by the
ratio of the country's GDP to the total GDP for which we have data available in a
given month. Note that both measures are adjusted for data availability so that
our aggregate measures are robust to changes in cross-sectional sample size as
new countries enter our sample (as data becomes available).
In Figure 12 we show the results for the global economy. We show this both
ways with the GDP weighted measure placing a greater emphasis on crises in
the larger countries. Figure 13 and Figure 14 then breaks this down by DM and
EM economies.
