US dollar steadies as markets await Iran war signals and central bank moves

The US dollar found its footing on June 1, 2026, stabilizing after a rough week as two massive wildcards loomed over global markets: the trajectory of US-Iran peace talks and upcoming central bank rate decisions.

Markets have priced in a 99% probability that the Federal Reserve will leave rates unchanged at its June meeting. That near-certainty means the real action is elsewhere, specifically in the Middle East, where tentative ceasefire extensions and the potential reopening of critical shipping lanes through the Strait of Hormuz have softened safe-haven demand for the greenback.

Geopolitics, oil, and the Bitcoin connection

Since the conflict erupted earlier in 2026, oil price volatility has been the transmission mechanism connecting geopolitical risk to inflation expectations, and from there to both Fed policy and crypto valuations. Bitcoin has been trading in a wide band between $66,000 and $80,000 during the early-to-mid 2026 period, with sharp swings closely tied to energy price moves and inflation signals.

The dollar index’s previous weekly losses were attributed to a combination of the ongoing geopolitical crisis and market digestion of May non-farm payrolls data. Analysts in Tokyo noted that the index had stabilized but remained sensitive to any shift in the conflict’s direction.

Oil trading on decentralized platforms has also surged during this period, as traders sought alternative venues to navigate market disruptions caused by the conflict.

Iran’s crypto footprint adds another layer

Iran’s central bank accumulated at least $507 million in USDT during 2025, forming part of what researchers have described as a broader $7.8 billion crypto ecosystem within the country.

For the broader crypto market, Iran’s significant USDT holdings represent both validation and risk. Validation because it demonstrates real utility at the sovereign level. Risk because it invites further regulatory scrutiny of stablecoin issuers and could become a political flashpoint if peace talks falter and sanctions enforcement tightens.

What this means for investors

With the Fed essentially on autopilot for June, the marginal driver of both dollar and crypto prices is geopolitical, not monetary. Bitcoin’s correlation with oil-driven inflation expectations has become one of the defining features of the 2026 trading landscape. If the Strait of Hormuz shipping routes continue to reopen and the ceasefire holds, lower oil prices could ease inflation fears and create a more favorable backdrop for risk assets. The $66,000 floor that Bitcoin has tested during this volatile stretch would face renewed pressure should hostilities resume.
