A virtual memorandum of understanding between the US and Iran, signed on June 15, has done something that months of economic data couldn’t: it gave central banks room to breathe.

The agreement establishes a 60-day ceasefire while setting the stage for deeper negotiations around Iran’s nuclear program. More immediately relevant to markets, it includes provisions to lift the US naval blockade on Iranian ports and reopen the Strait of Hormuz for commercial shipping. Oil prices promptly fell to three-month lows.

The oil-inflation pipeline

The Strait of Hormuz handles roughly a fifth of the world’s oil supply on any given day. When it gets disrupted, energy prices spike. When energy prices spike, everything from groceries to shipping costs follows.

The disruption earlier this year did exactly that, compounding inflationary pressures that central banks were already struggling to contain. With the strait now reopening and the naval blockade set to be lifted, one of the biggest supply-side inflation drivers of 2026 is unwinding in real time.

Oil’s slide to three-month lows is the market pricing in that relief. The dollar has weakened alongside it, a signal that traders expect reduced urgency for tight monetary policy. Equities and risk assets have gained as sentiment tilts toward risk-on positioning.

What central banks are watching

Before this deal, central banks faced an awkward situation. Domestic economic indicators in several major economies were softening enough to justify easing, but energy-driven inflation kept the door shut on rate cuts. The conflict in the region had essentially trapped monetary authorities between slowing growth and sticky price pressures.

If oil prices remain subdued through the 60-day ceasefire window, central banks will have considerably more flexibility to pivot toward accommodation.

Bitcoin and the risk appetite trade

Bitcoin surged above $67,000 in the wake of the announcement. Bitcoin has historically correlated with broader risk appetite in financial markets. When central banks signal easing, that comfort level increases.

That said, traders should calibrate their enthusiasm. The MoU is preliminary. A formal signing is planned for June 19 or 20 in Europe, but the harder negotiations around sanctions relief and Iran’s nuclear capabilities haven’t even started. Those discussions will play out over the next 60 days, and any breakdown could reverse the current optimism rapidly.

For crypto investors specifically, the key variable to monitor isn’t the deal itself. It’s what central banks do in response. If the Federal Reserve and its global counterparts use this window of reduced inflationary pressure to signal dovish pivots, Bitcoin and the broader digital asset market could see sustained tailwinds.

The 60-day ceasefire window essentially creates a countdown clock for markets. Every week that passes without escalation strengthens the case for policy easing. Every headline about stalled nuclear talks weakens it.
