Bitcoin surged to an intraday high of nearly $67,300 on June 15, 2025, after the United States and Iran reached a framework agreement to halt hostilities and reopen the Strait of Hormuz. The rally, which pushed open interest up more than 4% to 748,000 BTC, was driven by short-covering as funding rates remained negative near -1%. The geopolitical breakthrough also sent Brent crude down roughly 5% to $82.95, relieving inflation fears that had weighed on risk assets.
The US-Iran framework
The deal between Washington and Tehran de-escalated a months-long confrontation that had threatened oil shipments through the Strait of Hormuz, a chokepoint for about a fifth of global petroleum. The agreement came after weeks of back-channel talks and was announced jointly by both governments. Markets reacted swiftly: oil prices dropped, and Bitcoin reversed a multi-week slide as traders unwound bearish bets.
BOJ on the cusp of a historic hike
While the US-Iran news dominated headlines, the Bank of Japan was preparing for its own landmark event. The BOJ is expected to raise its policy rate from 0.75% to 1% by the end of June 2025 — the first hike since 1995. A poll found 94% of economists expect the move, and over three-quarters anticipate a follow-up increase to 1.25% in the fourth quarter. Japan's producer prices rose 6.3% year-over-year in May, well above the 5.5% forecast, while yen-based import prices jumped 25.5% year-over-year, giving the central bank cover to act.
Yen intervention and short positions
The yen held near 160 per dollar ahead of the BOJ meeting, a level that had already triggered record intervention. Japan spent ¥11.7 trillion defending the currency after it weakened past 160 in April and May. CFTC data through June 9 showed leveraged funds holding very large short exposure against the yen, setting up the potential for a sharp squeeze if the BOJ delivers a hawkish surprise. The central bank is also considering a pause in its bond-purchase taper starting in April 2027, potentially committing to a ¥2.1 trillion monthly JGB purchase floor — down from the current ¥2.7 trillion in the April-June 2025 window.
Bitcoin ETFs and the short squeeze
Bitcoin's bounce was largely a short-covering event. Open interest rose while funding rates stayed negative, a classic squeeze setup. The rally came after a rough stretch for spot Bitcoin ETFs, which saw outflows from May 27 to June 11, with only an $85.9 million net inflow on June 12 breaking that streak. A Citi note estimates that ETF flows account for roughly 45% of weekly Bitcoin price moves, meaning the outflows had been a significant drag. The US-Iran deal provided the catalyst to reverse that pressure, at least temporarily.
The BOJ's two-day policy meeting is set to conclude later this week. Markets are watching for the rate decision and any signals on the bond-buying taper. The yen's fate — and by extension, the next leg for risk assets — may hinge on how far the central bank is willing to go.
