OMCs' margins to be under pressure with crude above $100 per barrel: Report

•Crude oil above $100 per barrel may squeeze oil marketing companies (OMCs) due to frozen retail prices.

•Hindustan Petroleum Corp (HPCL) is most vulnerable with low refining-to-marketing ratio and high dependence on imports.

•Bharat Petroleum Corp (BPCL) is better placed with higher distillate yield and stronger balance sheet, but still faces risks.
