ASX Investor Live: Strait of Hormuz Blockade, Why Geopolitics Is Now Driving ASX Returns

If you are wondering why markets feel unstable again, geopolitics is back in control.

In April 2026, the combination of Middle East conflict, rising trade barriers and a more fragile China is no longer background noise. It is directly shaping which ASX stocks win and which ones come under pressure.

The most immediate catalyst is the blockade around the Strait of Hormuz. This is one of the most critical energy chokepoints in the world, with a major share of global oil and LNG trade normally moving through it. When that corridor is disrupted, energy markets react fast. That is exactly what we are seeing now.

What was the ASX  & Market Reaction

Oil has moved back above US$100 a barrel and LNG markets have tightened sharply. This is not just a temporary headline spike. It is a reminder that energy security remains fragile and that a single geopolitical shock can reprice entire sectors very quickly.

For ASX investors, the read-through is clear. Energy producers are the immediate beneficiaries. Woodside Energy, Santos, Beach Energy, Karoon Energy and Cooper Energy all have direct leverage to stronger oil and gas prices, which can flow into higher cash flow, stronger margins and upgraded earnings expectations. In our view, this remains one of the clearest geopolitical tailwinds in the market right now.

On the other side are fuel-intensive businesses that wear the pain. Qantas has already flagged the impact of higher fuel costs and is adjusting capacity and pricing in response. That is where the blockade stops being a macro story and starts hitting company earnings. Higher input costs compress margins, change consumer behaviour and force the market to rethink profit expectations.

This is not just an oil story

It is tempting to stop at energy, but that would miss the bigger picture. The Middle East shock is spreading through the global economy.

Shipping routes are becoming less reliable. Freight costs are rising. Fertiliser supply is under pressure. These are not isolated issues. They feed into food prices, inflation expectations and central bank decisions.

In our view, this is where second-order effects matter most. If inflation remains elevated because of energy and logistics disruption, interest rates may stay higher for longer. That has consequences for valuations across the ASX, particularly for growth stocks and rate-sensitive sectors.

Industrials, retailers and even parts of the mining sector can feel the pressure through rising costs and more cautious demand. Companies like Brambles, which are exposed to global logistics flows, are particularly sensitive to disruptions in freight and supply chains.

Trade wars are back and becoming structural

At the same time, global trade is becoming more fragmented. The United States has maintained a protectionist stance, particularly in metals and pharmaceuticals. Europe is now moving in the same direction, introducing tariffs and quotas to protect domestic industries. This is a structural shift rather than a temporary policy cycle. Countries are prioritising security and resilience over efficiency.

For ASX-listed companies, this creates a more complex environment. Businesses exposed to global trade flows may face distorted pricing and shifting demand patterns. BlueScope Steel and other industrial names are operating in a world where tariffs and quotas matter as much as underlying demand.

In our view, this reduces visibility on earnings and increases volatility. Companies with exposure to stable, aligned markets are likely to be more resilient than those reliant on more fragmented global trade.

China is still the swing factor for the ASX

China remains the most important external driver for the ASX. It is the dominant buyer of Australia’s bulk commodities, and its economic health underpins earnings for major miners.

Recent data suggests China’s growth has stabilised in the short term, but the outlook is becoming more complicated. Higher energy costs from the Middle East conflict are feeding into factory margins. Producer prices have started to rise again after a long period of weakness.

In our view, this creates a more fragile backdrop. It is no longer enough for China to grow. The quality of that growth matters. If margins are under pressure, demand for commodities can become less predictable.

For BHP, Rio Tinto, Fortescue, South32 and Champion Iron, this means the story is shifting. It is not just about volume and price. It is about how resilient Chinese industrial demand is in a more volatile global environment.

The investment takeaway

Geopolitics is now one of the primary drivers of ASX returns. Energy disruption, trade fragmentation and supply chain realignment are shaping earnings across multiple sectors.

In our view, the winners are relatively clear. Energy producers, gold miners and credible critical minerals companies are positioned to benefit from the current environment. The losers are also emerging. Fuel-intensive businesses, trade-exposed industrials and companies reliant on stable global logistics face increasing pressure.

The key point is this. This is not a temporary phase. The global system is becoming more fragmented and less predictable. Investors who understand that shift and position accordingly are likely to have an edge. Those who ignore it risk being on the wrong side of some very powerful forces.
