observed for other currencies as well. The British
pound’s share, for example, increases from around 2%
in the early sample period to nearly 10% by 2000 and
then falls back to 2.5% by 2010. The relative share of issuance
in Canadian dollars drops from 8% in 1993 to less
than 1% in 1995 just 2 years later. As noted above and in
previous studies, it seems unlikely that such extreme
variation in relative currency shares across time can be
reconciled with any type of natural hedging motive.
In addition to the challenges posed by the prevalence
of financial and government issuers and the extreme variation
in currency shares across time, previous research
