Pakistan’s stock benchmark KSE-30 Index surged as much as 9.2%, the most since 2008, in a rally that triggered an hour-long trading halt. The NSE Nifty 50 Index jumped as much as 3.5% in Mumbai, as both nations stepped back from the brink of war, allowing market participants to turn their focus back to the economic outlook for the South Asian nations.

“Given how quickly things were escalating last week, the developments over the weekend are a move in the positive direction,” said Brussels-based Vivek Dhawan, a fund manager at Candriam. “The focus could return to the Indian growth story.”

Investors had been nervous. The Nifty slid more than 1% on Friday — its steepest fall in over a month — while the rupee was one of Asia’s worst performers last week. Bond yields crept higher as risk premiums widened, although debt purchases by the Reserve Bank of India helped limit the declines. Pakistan’s key stock index had tumbled 9% since the April 22 attack in Kashmir, which prompted India to retaliate.

Foreign investors, who had been on a 16-day buying streak until Friday, may resume inflows, drawn by India’s positive economic signals, including prospects of an early US trade deal, ample liquidity, and anticipated interest rate cuts.

The Indian rupee rose as much as 0.9% versus the dollar in the offshore market. India’s bonds and currency markets are closed on Monday for a public holiday. The National Stock Exchange of India Ltd.’s volatility gauge fell to 17.2, its lowest level since April 30. The five-most traded Nifty 50 options were all bullish, with May 25,000-rupee calls expiring Thursday clocking the highest volume.

Still, the threat of renewed tensions remains, as India has yet to lift its abeyance on the Indus Water Treaty — a move that could harm a large part of Pakistan’s farm output. Meanwhile, a top Indian diplomat said that Pakistan violated the truce just hours after it was declared, a claim Pakistan has denied.

“Reports of violations within a few hours of the ceasefire announcement may cast some doubt on its sustainability,” Barclays Bank Plc. strategists including Avanti Save wrote in a note. The UK bank retained overweight on Pakistan credit and expects a reversal in Indian rupee losses.
