Following last week’s ABSI on the conflict in the Middle East, it is worth taking a closer look at recent developments surrounding the Strait of Hormuz and why it matters for global markets.

The Strait of Hormuz is a narrow waterway that sits between Iran to the north and Oman and the United Arab Emirates to the south. It connects the Persian Gulf to the Gulf of Oman and the wider global ocean shipping network.

In simple terms, it is the main exit point for oil produced in the Middle East.

Energy exports from Saudi Arabia, Iraq, Kuwait, Qatar and the UAE rely heavily on the Strait of Hormuz to reach global markets. At its narrowest point the strait is only around 33 kilometres wide, with shipping lanes in each direction just a few kilometres across.

Roughly one fifth of global oil consumption moves through the strait each day, making it the single most important oil transit bottleneck in the world. The route is also critical for LNG exports, particularly from Qatar, one of the world's largest gas exporters.

The Energy Market Transmission

Oil prices have moved above US$100 per barrel and market commentary is pointing to scenarios above US$120 if the disruption persists. That price level matters not just for energy investors but for the entire investment landscape.

Energy prices are one of the most powerful transmission mechanisms in financial markets. When oil moves sharply higher, it does not stay contained within the energy sector. It feeds directly into transport costs, freight, manufacturing inputs and corporate margins across a broad range of industries. The inflationary impulse from a sustained oil price shock is significant and the implications for central bank policy are material.

Gas markets carry equal weight in the current situation. Qatar is one of the world's largest LNG exporters and sends almost all of its LNG through the strait. The suspension of QatarEnergy production has tightened an already stretched global gas supply picture, particularly for Europe where storage levels are low. Higher gas prices amplify the inflationary pressure already flowing from oil and add a further layer of uncertainty to the growth outlook.

What Investors Should Watch

Three signals matter most from here.

The first is oil price direction. Whether Brent crude holds around current levels or pushes toward US$120 and beyond will determine how significantly the macro transmission plays out. A sustained move higher changes the earnings and policy calculus materially.

The second is inflation expectations. Central bank communication and inflation breakevens in bond markets will signal how much of the energy shock markets are pricing into the rate outlook. A notable shift in rate expectations from here would have consequences across equities, fixed income and currency markets simultaneously.

The third is the duration of the disruption. Markets can absorb a short, sharp shock. A sustained closure of the strait that restricts physical supply over weeks or months is a fundamentally different scenario with deeper implications for global growth.

The BPC view

Geopolitical shocks transmit through financial markets via a familiar sequence: energy prices move first, inflation expectations follow, and the rate and risk sentiment implications then flow through to equities, bonds and currencies. That sequence is now in motion.

The Strait of Hormuz disruption is an active, material development with direct implications for energy markets, inflation dynamics and portfolio positioning. The duration of the disruption will determine its ultimate impact, but the risk premium now embedded in energy markets is unlikely to dissipate quickly while the conflict remains unresolved.

Energy exposure, inflation sensitivity and currency positioning are the most important portfolio considerations in this environment. Investors should be reviewing their exposure across each of these dimensions as the situation develops.
