Asian Markets Close Lower, as Nifty Win Streak Stopped at Five

India’s Nifty 50 closed 0.93% lower at 23,775.10 on Thursday, ending a five-day winning streak as doubts over the durability of a newly announced US-Iran ceasefire sent ripples across Asia-Pacific markets just one day after a powerful relief rally.

The retreat marked a sharp reversal from Wednesday’s euphoria, when the Nifty had surged more than 3% alongside global equities on news of the truce. The broader BSE Sensex fell 0.96% in Thursday’s session, while regional peers also gave back gains. Japan’s Nikkei 225 dropped 0.73% to close at 55,895.32, with the Topix declining 0.90% to 3,741.47.

South Korea bore the brunt of the sell-off, with the Kospi tumbling 1.61% to finish at 5,778.01 and the small-cap Kosdaq down 1.27% to 1,076. Mainland China’s CSI 300 slipped 0.64% to 4,566.22, while Hong Kong’s Hang Seng Index traded 0.71% lower in its final hour.

The downturn came despite Wednesday’s announcement, when US President Donald Trump declared a two-week suspension of military operations against Iran via a Truth Social post. The ceasefire, contingent on Iran reopening the Strait of Hormuz and based on a 10-point Iranian proposal, had initially sparked a global risk-on rally that saw US indices jump over 1,000 points and oil prices plunge by double-digit percentages as the war premium evaporated.

Driving the Volatility in Global Markets

The optimism proved short-lived. Iranian parliamentary speaker Mohammed Bagher Ghalibaf publicly accused the United States of breaching the ceasefire agreement within hours of its announcement. Ghalibaf cited three specific violations: denial of Iran’s sovereign right to enrich uranium, Israel’s continued attacks on Lebanon, and a drone incursion into Iranian airspace. The accusations immediately undermined market confidence in the durability of the truce, triggering profit-taking across Asian trading floors.

For Indian markets specifically, the ceasefire carries significant economic implications. As a major net crude importer, the country stands to benefit substantially from lower oil prices if the truce holds. Wednesday’s sharp decline in Brent and WTI crude offered relief on inflation pressures and improved the outlook for corporate margins in energy-sensitive sectors including automobiles, airlines, cement, and chemicals.

However, the Reserve Bank of India struck a cautious note on Wednesday, warning that the Iran conflict had raised inflation concerns while also flagging downside risks to economic growth. The central bank’s commentary served as a reminder that geopolitical tail risks remain elevated, tempering the market’s initial enthusiasm about the ceasefire’s economic benefits.

The volatility in equity markets was mirrored across other asset classes. Oil prices, which had collapsed on ceasefire news, stabilized but remained volatile as markets toggled between relief and renewed concern. The US Dollar Index initially sold off sharply in a classic risk-on move, then rebounded as doubts about the ceasefire’s credibility widened, confirming that currency markets were also pricing in elevated headline risk.

The scale and speed of Wednesday’s rally—followed by Thursday’s retreat—highlighted just how fragile the prior conflict environment had been. Markets had priced in substantial war premiums across energy, shipping, and regional risk assets, and the rapid unwinding of those positions created powerful momentum in both directions.

Outlook

There is plenty still up in the air as far as what happens from here. In the bull case, the ceasefire holds and deepens into substantive negotiations, allowing oil to stabilize at lower levels and giving Asian central banks room to prioritize growth over inflation concerns. This outcome would support a resumption of the Nifty’s uptrend, with cyclicals and domestic demand stocks leading gains.

The bear scenario involves a collapse of the truce, triggering an immediate spike in oil prices and renewed stress on Strait of Hormuz shipping lanes. Such an outcome would force a rapid repricing of tail risk across emerging market equities and currencies, with energy stocks outperforming as the war premium returns.

The middle ground which may be most likely near-term, that we see an extended fragile truce characterized by sharp headline-driven swings. In this environment, we will have to get used to volatility being elevated for some time. Careful risk management is the theme of the year so far, it is treacherous out there, particularly if you hold any positions overnight.
