SAN FRANCISCO — There are three clocks running on the Iran crisis, and they are about to collide. The ceasefire expires April 22. The War Powers Resolution's 60-day limit arrives April 29. And the Iran oil sanctions waiver — the one that actually lets crude flow — expires April 19. [1]

Ten days from now.

The waiver, issued by OFAC in March, allowed countries to purchase Iranian oil loaded onto tankers before March 20 and discharge it before April 19 without triggering secondary sanctions. [2] It was a pressure-release valve — an acknowledgment that bombing Iran while banning its oil produced prices the global economy could not absorb. India, the primary beneficiary, moved fast. Reliance Industries purchased five million barrels of Iranian crude. Indian refiners resumed buying from Iran for the first time in seven years. [3]

Now the clock is running out, and the ceasefire has not addressed it.

The Hindu reported this week that Indian exporters are urging their government to revive an oil-for-rice barter mechanism with Iran — a pre-sanctions arrangement that would allow India to continue purchasing Iranian crude without dollar-denominated transactions that trigger US enforcement. [4] The barter proposal would pair discounted Iranian oil with Indian basmati rice exports, routing payments through Indian rupee accounts at Indian banks. It is creative. It is also, under current US law, almost certainly sanctionable.

The collision has three moving parts. First, if the waiver expires without renewal on April 19, every Iranian oil shipment in transit becomes legally radioactive. Tankers currently at sea carrying Iranian crude will need to discharge before that date or face the prospect of sanctions on their owners, operators, insurers, and port facilities. [2]

Second, the ceasefire does not address sanctions. Iran's ten-point plan demands full sanctions removal — a demand Trump has called "not good enough." The two-week pause covers military operations, not trade enforcement. Even if the ceasefire holds, sanctions snap back on schedule. [5]

Third, India's Chabahar port waiver expires April 26 — one week after the oil waiver. Chabahar is India's only direct trade route into Afghanistan and Central Asia that bypasses Pakistan. Losing it would collapse a decade of Indian infrastructure investment in the region. [1]

The CFR's analysis was blunt: "The waiver expires on April 19, 2026, unless renewed by OFAC. It does not include prohibitions on payments." [5] Translation: when the waiver ends, not just the oil stops — the banking channels freeze too.

Nobody in Washington has signaled an intention to renew. The ceasefire conversation has consumed all available diplomatic oxygen. The waiver, which affects the actual flow of oil that the ceasefire was partly designed to restore, sits in a bureaucratic limbo — too technical for the headlines, too consequential to ignore.

April 19 is ten days away. April 22 is thirteen. April 29 is twenty. Each deadline tightens a different vise. Together, they make the ceasefire's fragility not a diplomatic risk but an arithmetic certainty.
