Owe a Bank Millions, the Bank Has a Problem: Credit Concentration in Bad Times
How does a bank react when a substantial share of its borrowers suffer a large negative shock? To answer this question we exploit the 2014 collapse of energy prices using the universe of Mexican commercial bank loans. We show that, after the drop in energy prices, banks exposed to the energy sector increased their exposure to these borrowers even more, relaxing credit margins to their larger debtors in the sector. An increase of one standard deviation in a bank's ex-ante exposure to the energy sector increased the loan volume to borrowers in the sector by 18 percent and reduced interest rates ...

Related Exposures to Distressed Borrowers and Bank Lending
We study how banks’ exposure to a large set of related and suddenly-distressed borrowers impacts their commercial lending and risk taking. Using Mexican credit registry data, we examine the effect of the 2014 collapse in energy prices. After this shock, energy-exposed banks—regardless of their ex-ante financial health—raise further their exposure to the energy sector by expanding lending at looser credit terms to borrowers with higher expected losses, while recapitalizing through retained earnings. The shock is transmitted to non-energy firms—despite price controls on retail-energy ...
