 Latin American companies from oil behemoth Petrobras to cement maker Cemex, facing drastic coronavirus-linked revenue declines, are rushing to draw down credit lines amid a shutdown in local bond markets and a paucity of state aid. Since concerns about the coronavirus pandemic hit the region, disbursement on revolving credit lines have risen to an average of 65 from a previous 10 percent, said a senior executive at one of the largest U.S. banks in Latin America, adding he expects it to reach 100 in the short term. Brazils state-controlled oil company Petroleo Brasileiro SA has said it cashed out almost 9 billion from its revolving credit lines and Vale SA has drawn down 5 billion.
