UPI woos
A looming regulatory change threatens to disrupt consumer payments at fuel stations. Petrol pump dealers nationwide are urgently petitioning the ministries of finance and petroleum for an exemption from a new Unified Payments Interface (UPI) transaction fee set to take effect next month.
The dealer associations are protesting the proposed flat ₹5 merchant discount rate (MDR) applied to UPI fuel purchases exceeding ₹2,000. Operators have cautioned that the levy will severely strain their already-thin, fixed per-litre margins.
As Mint previously reported, the added financial burden could force several dealers to halt UPI acceptance for transactions above the ₹2,000 threshold to protect their profitability.
Global oil prices gain
Oil prices held above $100 as Iran and the United States exchanged new threats, following the Houthis ' attack on Saudi Arabia's capital. Brent gained toward $105 a barrel, while West Texas Intermediate was near $101.
At the weekend, Saudi Arabia issued air-raid alerts for Riyadh, the first in the capital since the height of the conflict in March and April, as well as warnings in Red Sea hubs including Yanbu. The kingdom has been facing threats from Iran-backed Houthis in Yemen.
"The closure of the East-West pipeline has materially altered the state of the oil market," Vivek Dhar, head of commodities at CBA, told Reuters. “We now estimate that oil markets have 5 to 10 weeks before global oil and refined product inventories deplete, compared to estimates closer to 15 to 20 weeks just a fortnight ago.”
Dhar said that this would increase pressure on Washington to make a deal with Iran, at least to restore some flows through the Strait of Hormuz and keep the Bab el-Mandeb passage open.
US-Iran latest news
Iran and the United States exchanged new threats on Sunday, with US President Donald Trump warning Iran would fail economically or face its leadership being wiped out if it didn't make a deal, and the Iranian military saying it would retaliate harshly to any fresh attack.
The conflict has looked stalemated for months, with no sign that either side was ready for concessions even as it has deepened a global energy crisis, cratered swathes of Iran's economy and spilt over into new regional escalations.
In a phone call with a Fox News reporter, Trump said Iran's leaders should make a deal, rot economically or be wiped out, the reporter said.
However, with Iran's President Masoud Pezeshkian expected in New York this week for the United Nations General Assembly, Trump said he would be open to meeting him, the Fox reporter added.
Trump has repeatedly made vague threats of major military escalations during the conflict that began with US and Israeli strikes on February 28, without carrying them out.
