The 3F squeeze: fuel, fertiliser and the foreign exchange to buy both

The most useful thing anyone said about India's macroeconomic position in May 2026 was a three-letter abbreviation. Finance minister Nirmala Sitharaman flagged what she called the '3F' challenge — fuel, fertiliser and foreign exchange — in a speech in Mumbai on May 25, and Indian Express reported the same day that the reference also covered gold and the rupee.

The framing is useful precisely because it refuses to treat the three as separate. They are the same bill arriving in different currencies. Crude and fertiliser are both imported, both are denominated in dollars, and a currency that weakens against the dollar makes both more expensive at the same time, before either price has moved.

Working the numbers rather than the narrative

The fuel leg is the one with public numbers attached. Indian Express reported on May 25 that the cumulative increase since May 15 had passed ₹7 a litre, with the oil marketing companies' losses down to about ₹600 crore a day. The sequence matters: four increases inside eleven days is a pass-through decision made in steps rather than one.

• Fuel: petrol and diesel up ₹3 a litre on May 15, then three further revisions by May 23, taking the cumulative rise past ₹7 a litre.
• Fertiliser: Indian Express reported on May 25 that India's fertiliser import bill is rising as the rupee weakens and Gulf supply routes are disrupted.
• Foreign exchange: gross FDI into India reached a record $95 billion in FY2026, but net inflows were $7.7 billion.

The FDI line is the one that gets skipped, and it should not. A record gross figure and a net figure an order of magnitude smaller are not in contradiction; they describe different things. The first is capital committed. The second is what actually stayed in the economy after repatriation and offsetting outflows. For a country whose external account matters most in a bad month, the second number is the relevant one.

The government's own review was cautious. The finance ministry's May economic review, reported on May 30, said the inflation outlook warrants vigilance and that consumption may face headwinds. That is a document conceding that the pass-through is not finished, which is consistent with everything else in the month's record.
