The announcement of a US-Iran roadmap towards a final agreement within 60 days, mediated by Pakistan and Qatar, triggered a sharp recalibration across emerging markets on Monday. Brent crude fell 1.66 per cent to $79.23 a barrel, far below its May peak of $126.41, as the interim reopening of the Strait of Hormuz—though later rescinded by Tehran—signalled a potential easing of the supply disruption premium. The immediate effect was a broad equity rally: the Nairobi Securities Exchange added Sh168.8 billion in market capitalisation to a record Sh3.63 trillion, Nigeria’s NGX gained N1.52 trillion, India’s Sensex rose 291 points, and Brazil’s Ibovespa climbed 1.21 per cent.

The mechanism was a swift unwinding of inflation hedges. Cheaper crude reduced the expected pressure on import bills and consumer prices, prompting foreign institutional investors to return to markets they had fled during the war-risk spike. On the NSE, foreign investors turned net buyers of Sh432 million, lifting Safaricom, Absa Bank, and KCB Group. In Mumbai, foreign portfolio inflows reached Rs 4,859 crore on the preceding Friday, and blue-chips Reliance Industries and HDFC Bank led Monday’s recovery. In Lagos, bargain hunting in tier-one banking stocks—GTCO, Zenith Bank, and First HoldCo—drove the All-Share Index up 0.97 per cent, even as market breadth remained negative, indicating a concentrated rather than broad-based rebound.

Local catalysts amplified the global tailwind. In São Paulo, the National Treasury cancelled a scheduled auction of inflation-linked NTN-B bonds, a move viewed by analysts as a signal that authorities recognised dysfunctional conditions in the fixed-income market. The cancellation sent long-dated interbank deposit futures rates tumbling—the January 2031 contract fell from 14.90 per cent to 14.685 per cent—and propelled the Ibovespa higher, with BTG Pactual units gaining over 3 per cent after J.P. Morgan upgraded the stock. The Treasury’s action followed a Copom rate decision the previous week that markets had read as ambiguous, and the central bank complemented it with a combined dollar-sale and swap operation to stabilise the real. In Nairobi, corporate transactions provided an additional floor: Absa Group’s plan to raise its stake in its Kenyan subsidiary and the partial unblocking of the EABL-Diageo share sale supported valuations even as a fresh court petition froze the brewer’s deal.

The gains hold, for now, despite Tehran’s Saturday announcement that it had again closed the Strait of Hormuz, alleging breaches by Washington and Israel. Analysts in Nairobi and Mumbai note that the diplomatic framework, however fragile, has shifted the baseline from open conflict to a negotiated timeline. The next factual milestones are the release of the Copom minutes on Tuesday, which will clarify the Brazilian central bank’s reaction function, and any follow-up Treasury buyback operations should bond-market stress resume. Globally, the 60-day negotiation window now serves as the clock that markets will watch for signs of a durable détente or a return to disruption.
