Strait of Hormuz traffic won’t return to normal until end of the year, traders say

There is a high probability that shipping traffic in the Strait of Hormuz will not return to normal this year, according to prediction market traders.

In Kalshi, there is now a 66% chance that the strait will not see normal traffic flow before January 2027. The probability of returning to normal before August has dropped from 66 percent to 21 percent in the last two weeks. The market defines “normal traffic” as the seven-day moving average of over 60 ships passing through the strait.

The latest change in rates came as Iran and Israel launched attacks on each other on Sunday for the first time since a ceasefire in April. Iran launched a missile into northern Israel on Sunday after warning the country that it was violating the ceasefire by repeatedly attacking Lebanon. Israel said it had launched a “large-scale attack on strategic defense systems” in response.

Trump also hinted last week that the strait would remain closed through Labor Day.

“I don’t know. I mean, I think it could happen (closed for Labor Day), but it’s very unlikely. I think we’ll make it happen. I think this will work itself out pretty quickly,” Trump said in the Oval Office. he said.

While Iran’s Foreign Ministry announced that the country stopped attacks on Israel on Monday, traders in Kalshi did not notice a dramatic change in strait traffic.

US President Donald Trump also insisted in a Truth Social post that negotiations were still ongoing.

Trump wrote Monday: “Israel and Iran, both sides want an immediate ceasefire! Final negotiations on ‘peace’ are ongoing, subject to ignorance or stupidity prevailing. The blockade will remain in effect and continue with full force and effect until the ‘Final Agreement’ is reached. Things must move quickly.”
