IRPC has announced plans to offer three bond tranches with maturities of three, five and seven years to general investors, offering fixed interest rates ranging from 2.70% to 3.85% per annum. Interest payments will be made every six months throughout the tenor of the bonds.
The offering is expected to open for subscription between June 15 and 17, 2026, through six leading financial institutions in Thailand. Both the company and the bonds were assigned a credit rating of “A-” with a “stable” outlook by TRIS Rating, reflecting IRPC’s strengths in integrated refining and petrochemical operations, liquidity management and long-term business resilience as a strategic company under PTT Public Company Limited.
Thorasaeng Chaipravit, Senior Executive Vice President, Accounting and Finance of IRPC, said geopolitical tensions in the Middle East, particularly the closure of the Strait of Hormuz, tightened global oil supply and driven a sharp increase in crude oil prices, contributing positively to the company’s refinery performance during the first quarter of 2026.
She added that IRPC recorded a 22% increase in revenue from net sales, while Market GIM rose 14% from the fourth quarter of 2025. The improved performance was supported by higher average selling prices in line with rising crude oil prices, widening diesel spreads and increasing Dubai crude benchmarks.
Despite the stronger performance, IRPC continues to maintain cautious business management, prioritising operational stability, proactive risk management and financial discipline amid volatility in the global energy market.
The bond issuance aims to strengthen IRPC’s capital structure, support sustainable growth and reaffirm the company’s position as one of Thailand’s leading integrated petrochemical and petroleum companies. The company stated that the investment structure was designed to provide flexibility across different investment horizons while reinforcing long-term business stability.

* Three-year bonds with fixed interest rates between 2.70% and 2.80% per annum
* Five-year bonds with fixed interest rates between 3.10% and 3.30% per annum
* Seven-year bonds with fixed interest rates between 3.65% and 3.85% per annum
