Brent crude has surged above $90 per barrel, climbing 3.2% early Monday to reach levels unseen since mid-June. This upswing culminates a 14% increase last week and a near 30% rebound from July’s low of about $71, driven by escalating US-Iran tensions disrupting the Strait of Hormuz shipping lanes.

Geopolitical Tensions and Oil Supply Constraints

The US has intensified military strikes against Iran, marking an eighth consecutive night of attacks, while simultaneously enforcing a blockade on Iranian ports. Tehran's retaliation includes declaring the Strait of Hormuz closed to all unauthorized vessels this passage handles roughly one-fifth of global oil trade. The shrinking traffic through this critical chokepoint has ignited fears of supply shortages, with recent Iranian strikes damaging Kuwaiti power and water infrastructure, exacerbating regional instability.

Economic Feedback Loop: Inflation and Monetary Policy

Energy price spikes threaten to reverse gains in US inflation made earlier this summer, as oil's climb from $71 to over $90 counteracts the 5.7% drop in energy costs that had contributed to a 0.4% monthly price decline in June the largest since April 2020. Bond markets reacted swiftly: the 10-year Treasury yield rose to 4.55%, nearing a two-month peak, signalling increased investor caution.

The Federal Reserve’s hawkish posture appears reinforced by these developments. Although new Fed Chair Kevin Warsh opted to maintain stable rates in June, inflation pressures linked to higher energy costs increase the likelihood of a July rate hike. Market odds for a Fed increase on July 28-29 have risen sharply, doubling from 18% to 36% earlier this month before pulling back to 14% at present.

Implications for Cryptocurrency Markets

This environment poses challenges for cryptocurrencies, especially Bitcoin. Rising interest rates typically weigh on risk assets, and BTC’s recent recovery shows signs of faltering with persistent selling pressure at each rally attempt. Prior research from BeInCrypto revealed that during an earlier phase of conflict from February 28 to June 17, traditional stocks outperformed Bitcoin as a safer hedge against war-induced volatility.

If oil prices remain elevated above $90, the probability of a Fed rate hike could shift firmly from a risk scenario to the expected norm, exerting fresh downward pressure on crypto markets. Traders monitoring the July Fed meeting will be reacting not only to policy signals but also to ongoing geopolitical developments that keep oil supply concerns front and center.
