ONGC Approves $500 Million Guarantee to Back MRPL Crude Imports From Saudi Aramco

NEW DELHI — State-owned energy major Oil and Natural Gas Corporation Ltd (ONGC) announced on Tuesday, July 28, 2026, that its Board of Directors has approved a Parent Company Guarantee (PCG) of $500 million in favor of Saudi Arabian Oil Company (Saudi Aramco). Issued on behalf of its refining subsidiary, Mangalore Refinery and Petrochemicals Ltd (MRPL), the guarantee is designed to facilitate and secure crude oil imports from the Saudi oil exporter over a two-year tenure spanning September 1, 2026, to August 31, 2028.

Operational Mechanics and Financial Framework

Under the terms submitted in regulatory filings to Indian stock exchanges, the parent company guarantee provides credit backing that enables MRPL to procure long-term crude shipments from Saudi Aramco without straining short-term balance sheet liquidity.

• Guarantor Entity: Oil and Natural Gas Corporation Ltd (ONGC).

• Beneficiary Entity: Saudi Arabian Oil Company (Saudi Aramco).

• Primary Obligor: Mangalore Refinery and Petrochemicals Ltd (MRPL).

• Guarantee Quantum: USD $500 million.

• Tenure: September 1, 2026, to August 31, 2028 (24 months).

The approval ensures uninterrupted commercial terms and credit lines between MRPL and Saudi Aramco, supporting the refining facility's baseline feedstock requirements at its Coastal Karnataka processing hub.

Refining Capacity and Feedstock Strategy

MRPL operates a modern coastal refinery at Mangalore with a total nameplate capacity of 15 million metric tons per annum (MMTPA). The refinery relies heavily on Middle Eastern crude slates, with Saudi Aramco remaining one of its principal overseas suppliers.

The $500 million financial guarantee underpins crude purchase agreements, allowing MRPL to lock in reliable import volumes along the West Coast energy corridor. By utilizing ONGC's stronger corporate rating and balance sheet, MRPL mitigates credit risk requirements typically associated with large-scale international energy trade contracts.

Strategic Significance for Domestic Energy Security

The approval comes amid ongoing vigilance regarding global maritime trade routes and international crude procurement costs. With India importing nearly 90% of its domestic crude oil requirements, establishing stable bilateral credit arrangements with major state oil exporters provides structural security for regional refining operations.

For institutional investors, the parent guarantee represents standard corporate treasury management within integrated oil and gas holdings, enabling subsidiaries to leverage parent equity strength to optimize operational trade finance.
