Iran said the port blockade, oil sanctions and regional attacks must end as tensions with the United States continued to shape the region’s security and energy outlook on 21 Oct 2026. Tehran’s demands keep maritime access, crude exports and regional stability at the centre of the standoff.
The development matters for Indian energy stocks because any change in shipping access or oil flows can affect crude prices, freight costs and refinery margins. OI Charts data as of 19 Oct showed ONGC at ₹225.00, up 1.35% on the day, while its futures open interest fell 0.9% in a short-covering move. The stock remained 3.4% lower over 20 sessions and traded near its 52-week low of ₹218.53 recorded on 8 Oct.
Reliance closed at ₹1,202, down 0.76% on 19 Oct, although it was up 3.7% over five sessions. Its futures open interest rose 0.3%, indicating a short build-up, while the stock remained 2.0% lower over 20 sessions. These contrasting derivatives signals show different near-term positioning across the energy complex rather than a uniform market response. ⚡
Key Points:
• ONGC’s futures premium was -0.20%, with a put-call ratio of 0.45. The nearest expiry is 27 Oct 2026, with max pain at ₹225, the largest call open interest at ₹225 and the largest put open interest at ₹220.
• Reliance’s futures premium was 0.45%, with a put-call ratio of 0.61. Its nearest expiry is 27 Oct 2026, with max pain at ₹1,210, the largest call open interest at ₹1,250 and the largest put open interest at ₹1,160.
• The next market-moving signals are any verified change in the blockade, sanctions or regional attacks, alongside crude prices, shipping rates and official statements from Washington and Tehran. Energy traders will also watch whether ONGC holds ₹220–₹225 and whether Reliance moves toward the ₹1,210–₹1,250 options area.
The immediate implication is continued sensitivity in energy and shipping-linked assets, but the article did not report a negotiated settlement or a confirmed change in oil supply. 📌
