Bitcoin price slides to $61K: What the Bürgenstock collapse and Warsh's hawkish FOMC mean for BTC

Bürgenstock shock

The formal signing of the US-Iran peace framework never happened. After both sides electronically signed the 14-point Islamabad Memorandum of Understanding earlier in the week, the in-person ceremony at the Bürgenstock resort in Switzerland was called off when US Vice President JD Vance canceled his travel and the Iranian delegation stood down. 

The Swiss Federal Department of Foreign Affairs confirmed preparations at Bürgenstock remain in place, but no date has been set.

The Islamabad MOU requires technical nuclear negotiations to take place within a 60-day window. That clock is ticking and the framework is not permanently off the table — but the indefinite delay is a setback for markets that had priced in imminent resolution.

Resulting impact on BTC’s price

BTC fell from the low $65,000s to around $61,000 as long positions built on peace optimism were liquidated; the total crypto market cap dropped nearly 2% to $2.21 trillion. 

Prediction platform Polymarket had been pricing a rising 37% probability of a permanent deal within the month — those positions unwound quickly. Equity markets mirrored the move: major US indices fell over 1% on June 17 as the Warsh FOMC shock landed, before staging a partial recovery on June 18 as investors repositioned ahead of the Juneteenth holiday closure on June 19. 

Energy markets reversed course too; WTI crude settled at $76.60 and Brent at $79.85, both bouncing from multi-month lows as Strait of Hormuz risk returned to the table.

Warsh's 'missing dot' and what it means

Before the Bürgenstock news broke, markets were already digesting a sharper-than-expected FOMC outcome. The hold at 3.50% to 3.75% passed 12-0 — no surprise — but the surrounding communication marked a clean break from the Powell era.

The policy statement had easing bias language removed. The dot plot told a similarly hawkish story: the median 2026 year-end funds rate projection rose to 3.8% from 3.4% in March, with nine out of 18 members pencilling in at least one hike this year. Seventeen out of 18 officials flagged upside inflation risk and the 2026 headline PCE forecast was revised sharply higher to 3.6% from 2.7%.

Warsh then declined to submit his own dot — the detail markets had been watching most closely. Per CNBC's post-meeting coverage, he cited concerns about the tool's usefulness and announced five task forces to review the Fed's communications framework, inflation model, balance sheet, data sources and productivity and jobs metrics — the last of which explicitly covers AI's role as a disinflationary force. 

Without a Warsh dot anchoring rate expectations, every incoming CPI, PCE and payrolls print becomes a larger market event, which may lead to a more volatile market as it adjusts to a new communication regime. 

Effect on altcoins and ETF flows

Altcoins absorbed heavier losses than BTC in the session following the double shock. ETH slid below $1,700, with selling compounded by news of a prominent Ethereum Foundation director's departure. 

SOL dropped below $70, giving back its multi-day gains despite isolated support from spot SOL ETF inflows. XRP fell to about $1.13 as traders refocused on support near $1.14.

Institutional flows confirmed the risk-off rotation. Spot BTC ETFs recorded outflows of $82.17 million on June 17 and $90.66 million on June 18. 

Combined BTC and ETH ETF outflows hit $111 million on June 18 alone.

Bitcoin price: Levels to watch

BTC now faces a two-front headwind. On the geopolitical side, the 60-day MOU clock means Bürgenstock is not permanently shelved — a rebooked signing date would likely trigger a rapid reversal of the peace-unwind trades. 

On the monetary side, the pace of incoming inflation data and Warsh's task force conclusions may determine whether the Fed's new communication regime becomes a tailwind or a persistent drag on risk assets through the second half of 2026.
