Bitcoin traded at $63,030 on June 18, down about 2% on the day, and by press time June 19 it approached $62,450. The slide came as two major macro forces pulled in opposite directions: a surprise US-Iran deal that opened the Strait of Hormuz and sent oil prices tumbling, and a hawkish Federal Reserve that made rate hikes a live possibility again.
A 60-day window in the Strait
President Donald Trump signed the Islamabad Memorandum of Understanding with Iran on June 18, committing Iran to ensure safe commercial passage through the Strait of Hormuz for 60 days. The US, in turn, will end its naval blockade on Iranian ports within 30 days. Within hours, three Saudi-flagged supertankers carrying 6 million barrels of crude sailed through the strait — a chokepoint that handles roughly 20% of global oil supply.
Brent crude settled near $79.85 on June 18, and WTI at $76.60. But the Lloyd's Market Association warned that something approaching normal conditions could take months, and mine-clearance operations in the strait are incomplete. The 60-day timeline means the reopening is conditional — and reversible.
Fed dots turn red
The same day, the FOMC held its target range at 3.50%-3.75%, but the dot plot shifted sharply. Nine of 18 Fed policymakers now expect at least one rate hike this year, up from zero in March. Six of those nine project more than one 25-basis-point increase. The Fed's median year-end PCE inflation forecast jumped to 3.6% from 2.7% in March.
The US dollar index hit a one-year high of 100.80 after the statement. Fed funds futures priced a 68% chance of a rate hike by September. That's a stark reversal from just weeks ago, when cuts were the dominant bet.
Bitcoin caught between falling oil and rising rates
Lower oil prices are disinflationary — good for risk assets in theory. But a stronger dollar and higher rate expectations are the opposite. Bitcoin's 2% drop on June 18 reflected that tug-of-war. If oil keeps falling and shipping normalization accelerates, the disinflationary signal could feed into Fed inflation forecasts, potentially reducing hike odds and weakening the dollar. That scenario would favor crypto. But for now, the market is pricing the Fed's hawkish shift as the more immediate factor.
The timing isn't great. Bitcoin had been struggling to hold above $63,000, and the new macro headwinds add pressure. The next concrete milestone: the July FOMC meeting, where another dot plot shift or a surprise hike could reset the landscape. Meanwhile, the 60-day Strait of Hormuz clock is ticking — and the mines are still in the water.
