Private Information in Currency Markets
George Nishiotis, University of Cyprus
Using daily abnormal currency returns for the universe of countries with flexible exchange rates, we document local currency
depreciations ahead of public sovereign debt downgrade announcements. Consistent with the private information hypothesis,
the effect is stronger in lower institutional quality countries and holds after we control for concurrent public information and for
publically available rumors about the forthcoming downgrades. Our results persist when abnormal currency returns are adjusted for
carry and dollar risk factors, interest rate differentials and local stock market returns. Finally, the currency depreciations are permanent,
providing evidence for a link between fundamentals and currency markets.
