Brent and US crude both reached their highest levels since July 31 as investors assessed conflicting signals surrounding negotiations and the prospect of restoring normal shipping through the strategic waterway. Reuters reported that shipping traffic through Hormuz had fallen sharply, with only six vessels using the passage on Monday compared with a pre-war norm of roughly 130 to 140 vessels.
The Strait is a critical artery for global energy markets. A prolonged reduction in shipping would increase the risk premium attached to crude oil and could raise costs for refiners, manufacturers, airlines, logistics operators and other fuel-intensive businesses.
The immediate market response reflects the sensitivity of energy prices to expectations rather than only physical supply. Even without a complete interruption of oil flows, uncertainty over shipping routes can influence freight costs, insurance premiums, inventories and corporate hedging decisions.
Higher crude prices could also complicate the inflation outlook. Energy is an important input into transportation, manufacturing and distribution, meaning sustained increases can feed into broader operating costs and consumer prices.
For central banks, renewed energy inflation would make monetary-policy decisions more difficult, particularly if underlying price pressures remain persistent.
Governments and energy companies are also likely to reassess supply resilience, strategic reserves and alternative transportation routes if disruption continues.
The central question for markets is whether diplomatic efforts can restore confidence in Hormuz traffic or whether geopolitical uncertainty will keep a substantial risk premium embedded in oil prices.
Investors will be watching shipping volumes, negotiations between the United States and Iran, crude inventories and any further attacks on commercial vessels.
