KPMG warns leaders to plan for Iran conflict ripple effects

Iran is pushing client leaders to look past the headlines and stress-test the chain reaction underneath: energy costs, shipping routes, supplier resilience, financing decisions and market volatility. KPMG’s Global Economic and Geopolitical Outlook webcast on June 25 is an evergreen format, but this episode is sharper, built for senior leaders who need to act before uncertainty hardens into a budget decision or a supply problem.

Why KPMG is framing this as a decision memo

KPMG is running three regional broadcasts of the same 60-minute session, and the message is the same across Australia, Bahrain, South Africa, Singapore, China and other country pages: the conflict in Iran is creating ripple effects across energy, supply chains and global markets. The China registration page puts the session at 13:00 CST on June 25, 2026, and the lineup brings together KPMG firm Regional Chief Economists, KPMG International’s Global Geopolitics Lead and other senior advisors.

That cast tells you what KPMG thinks clients want right now. They are not asking for a geopolitical lecture. They want someone to turn fast-moving headlines into decisions that can survive a board meeting, a budget review and a procurement reset.

The questions leaders are asking

Should we wait or move now?

This is the first question landing on partners and managers because the webcast is built around second-order effects, not just the immediate oil-price headline. KPMG says executives should assess how pressure on energy markets, supply chains and global trade should change investment timing, capital allocation and risk posture.

In practice, that means clients are asking whether a project can still clear hurdle rates if freight, fuel and financing costs move together. It also means the people closest to the work need to translate geopolitics into operating choices quickly, because a delayed call on capex or sourcing can become a margin problem before it becomes a strategy memo.

Where do supply chains break first?

This is where the abstract becomes concrete. Before the conflict, vessels transiting the Strait of Hormuz accounted for nearly 35% of global seaborne crude oil trade, 20% of refined petroleum product trade and about 20% of liquefied natural gas trade. That is why a regional shock in or around Iran can turn into a pricing and logistics problem for companies far outside the Middle East.

The World Bank said in March that clients in emerging markets were already reaching out as the conflict began to affect commodity prices and logistics. Its April Commodity Markets Outlook called the war in the Middle East a historic shock and said it caused the largest oil supply loss on record. For KPMG teams, that means the supply-chain conversation is no longer about resilience as a slogan; it is about which supplier, lane or energy input becomes the first point of failure.

What belongs in forecasts and controls?

For audit, tax and advisory teams, this is where the issue stops being macro commentary and starts becoming daily client work. Geopolitical risk now reaches client forecasts, going-concern assumptions, tax planning, transfer pricing, procurement strategy, financing and controls over supply-chain disruption.

That is the sort of problem that pulls different service lines into the same conversation. Audit needs the assumptions to hold in the numbers, tax needs to understand how changing trade and sourcing patterns affect planning, and advisory needs to help clients decide whether to absorb, hedge or redesign the exposure. The practical consequence for KPMG professionals is tighter coordination and faster synthesis, because clients are not buying a separate answer from each team.

Is the macro backdrop already bad enough to change plans?

The outside signals say the pressure is already real. On April 28, the World Bank projected energy prices would surge 24% in 2026 to their highest level since 2022 because of the Middle East war. On June 11, it said the conflict is expected to slow global growth to the lowest rate since the onset of COVID-19.

The IMF has been making a similar point from another angle. On March 3 it said it was seeing disruptions to trade and economic activity, surges in energy prices and volatility in financial markets. Its April 2026 World Economic Outlook projected global growth at 3.1% in 2026 and 3.2% in 2027 if the conflict remains limited in duration and scope. Even that softer case still leaves leaders planning for slower growth, which is why the webcast is aimed at helping them act before the market forces a worse decision.

The International Energy Agency has also launched a 2026 Energy Crisis Policy Response Tracker and a Middle East energy-markets topic page, underlining how quickly governments are trying to track both emergency responses and dependence on Middle Eastern oil and gas.

What the webcast gives KPMG teams in practice

The value for KPMG staff is not just that the webcast exists, but that it creates a shared language for client conversations. Regional chief economists and the Global Geopolitics Lead can help turn broad headlines into concrete questions about procurement, debt costs, supplier concentration and timing, which is exactly what client leaders are asking when they call after a market move.

For managers, that becomes a staffing filter as well. The people who can move from geopolitical shock to client-ready implications, in one meeting and without hand-waving, are the ones who become indispensable on engagements that cut across audit, tax and advisory. In a firm built on judgment, this is the kind of issue that rewards fast synthesis over polished commentary.

The near-term job is not to predict the next headline. It is to decide where a shock lands first, what it does to the numbers and which decisions cannot wait until the volatility has already shown up in quarterly results.
