Muscat: Indian Rupee topped INR250 per Omani rial mark on Monday, exchange houses in Oman confirmed. The rupee opened on a weak note and slumped to an all-time low of 96.25 in early trade on Monday (May 18, 2026), as elevated crude oil prices, global uncertainty, and a stronger dollar continue to remain key risks for the domestic unit. Forex traders said higher crude oil prices, a stronger US dollar, and ongoing geopolitical tensions have together created a difficult environment for emerging market currencies, and the rupee is now clearly reflecting that stress.
