Yields on 10-year US, German, and UK government bonds rose sharply and hit a 4-week high on Wednesday, when US President Donald Trump stated the ceasefire with Iran had ended [1]. His statements accelerated the bond sell-off that was already in progress due to the newly revived military activity in the Middle East and drove prices of crude oil higher throughout the day.

Invest NowWhat Trump Said, and What Triggered It
Speaking to reporters at a NATO summit in Ankara, Turkey, Trump said, “I think it’s over. I don’t want to deal with them any more,” adding that US negotiators wanted to keep talking [2].
This followed a rapid, escalatory chain of responses. The US had retaliated to Iranian strikes on US allied shipping in the Strait of Hormuz with airstrikes and put a stop to the legal sale of Iranian oil [3]. A senior US official stated that Iran then conducted strikes on US interests, deepening the concerns that the peace deal reached in late June was no longer valid, and drove oil prices further up [1].
First Abu Dhabi Bank analysts also mentioned that there was no real ceasefire agreement in the June memorandum of understanding between the US and Iran, just, as they put it, an agreement to discuss the negotiations [1].

Two things are making the dollar more valuable: a global preference for safe investments amid geopolitical tensions and higher crude prices benefitting the US as a net oil exporter.
Impact on Indian Markets
This situation directly impacted Indian markets due to India’s reliance on Gulf oil imports and the Strait of Hormuz shipping corridor.

As a significant oil-importing country, an ongoing increase in crude oil prices directly affects the Indian economy. It increases the trade deficit, puts pressure on the rupee, and poses an increasing risk of inflation, all of which the RBI will be keeping an eye on in the coming days.

The Bottom Line
With a serious disruption in tanker traffic passing through the Strait of Hormuz — one of the world’s major oil shipping routes — and a sharp increase in hostile activity, markets are preparing for more volatility with oil, currencies, and interest rates. The primary question for global markets, including India, is whether this situation will be a sustained disruption or a single major disruption in the ongoing on-again, off-again negotiations.
