Why is the dollar gaining strength amid rising US-Iran tensions?

The dollar is advancing due to its enduring safe-haven status as escalating fears of a return to full-scale war between the US and Iran drive investors to seek shelter; additionally, the US launched strikes on Iran and revoked a waiver allowing Tehran to sell oil globally after attacks in the Strait of Hormuz, causing oil prices to surge and equities to retreat — and since most oil trading is conducted in dollars and the US is the world’s largest oil producer, the currency benefits from higher energy prices.

What do market data and strategist views suggest about current dollar sentiment and near-term Fed policy expectations?

Dollar sentiment has turned the most bullish since 2015, with wagers on a stronger dollar reaching nearly $40 billion as of June 30, according to CFTC data; however, strategist Erik Nelson at Wells Fargo describes the current rally as 'getting tired', citing diminished odds of a July rate hike — interest-rate swaps show only about a 33% chance of a Fed increase later this month — and recent weak US hiring data has already curtailed rate hike expectations and weighed on the dollar, leaving the dollar gauge flat so far this month.
