The paper Why do firms default on their foreign currency loans? The case of Hungary by Dzsamila Vonnák is about to be published in the Journal of International Money and Finance.
The paper isolates the effect of the choice of foreign currency on the loan performance of firms borrowing in different currencies in crisis times. The author uses a novel micro-level dataset from Hungary to decompose the factors contributing to the worse loan performance of foreign currency borrowers compared to local currency debtors. She finds that foreign currency denomination can worsen loan performance considerably, while selection also contributes significantly to the default differences. On the one hand, per se less creditworthy firms borrowed in foreign currency and during the crisis the foreign currency shocks further weakened their loan performances. On the other hand, more creditworthy firms that were also well-prepared for the currency risks also borrowed in foreign currency. My results suggest that not the institution of foreign currency lending per se that should be blamed for the bad loan performance of foreign currency borrowers, instead one should consider the characteristics of the borrowers.
