According to Reuters, five U.S. regional banks put aside millions of dollars during Q1/16 to cover potential losses from loans to the energy sector.

Reuters said provisions at the five banks (Comerica, Regions, Key, SunTrust and Fifth Third) rose to $570 million during Q1/16 compared to $222 million in Q1/15.

Citing data from a Deloitte study, Reuters also said that if oil prices remain weak, up to a third of all oil producers could enter bankruptcy this year.
