March 19 2026 – War-proofing wealth must be investors' number one priority amid escalating tensions across the Middle East, warns the CEO of global financial advisory organisation deVere Group.
The warning from Nigel Green comes as missile strikes hit Iran's South Pars gas field—the world's largest—Qatar reports “extensive damage” at the Ras Laffan LNG terminal, and Brent crude surges more than 4% to push past $110 a barrel, highlighting the growing threat to global energy supply and trade flows.
A vessel has also been struck east of the Strait of Hormuz, underlining the growing risks to global shipping routes.
He says: “Investors need to review their wealth strategies following direct attacks on critical energy infrastructure and rising risks to the movement of oil and gas through key routes like the Strait of Hormuz.
“This is already feeding through into prices. And it appears to be escalating.”
Roughly a fifth of the world's oil supply passes through the Strait of Hormuz, alongside a substantial share of global LNG.
Qatar's Ras Laffan alone accounts for around 20% of global liquefied natural gas output, much of it destined for Asia.
Disruption at this scale carries serious implications for inflation, corporate margins, and global growth.
Nigel Green warns that the situation bears comparison with the energy shocks of the 1970s, when supply disruptions triggered prolonged inflation and forced a major repricing of risk across global markets.
He says: “There are clear parallels with the 1970s energy crisis. Supply shocks of this nature rarely remain contained. They ripple through economies, push up costs, and force investors to rethink positioning.
“Markets are only beginning to adjust to that reality.”
He stresses that “portfolios built around assumptions of stable energy prices and frictionless global trade are increasingly vulnerable.”
The deVere CEO adds that investors need to think carefully about how their wealth is positioned in this environment. War-proofing is about resilience—ensuring portfolios can withstand disruption rather than relying on stability,” Nigel Green adds.
He outlines key considerations for investors seeking to strengthen resilience.
Gold should be considered as a diversifier within portfolios. “Periods of geopolitical escalation typically increase demand for hard assets that can help offset currency volatility and market stress.”
Energy exposure is also becoming more relevant. “Oil and gas producers, particularly those operating outside high-risk regions, are likely to benefit from sustained supply constraints and elevated prices as markets adjust to disruption.”
Commodities more broadly may warrant attention. “Rising energy costs often feed through into wider input prices across the global economy, reinforcing their role during inflationary periods.”
Sector exposure should be reviewed. “Industries reliant on cheap fuel and uninterrupted global logistics, including airlines and parts of heavy manufacturing, face increasing pressure if disruption persists.
“In contrast, sectors linked to energy, defence, and infrastructure may see stronger demand as governments and companies respond to heightened risks.”
Geographic diversification remains important. “Concentrated exposure to regions heavily dependent on Middle East energy, particularly parts of Asia, “may increase vulnerability, while broader global exposure can help reduce risk.”
Currency positioning should also be assessed. “Energy-importing economies may come under pressure, while the US dollar and commodity-linked currencies have historically strengthened during periods of geopolitical stress and rising oil prices.”
Nigel Green says: “This is a structural shift in how risk is being priced. Energy infrastructure is being targeted, and supply chains are under strain in a way that echoes previous global shocks.
“Investors who remain positioned for calm conditions are taking on unnecessary risk.”
He concludes: “History shows that energy shocks reshape markets in profound ways.
“The 1970s crisis drove inflation higher, altered capital flows, and rewarded those who were diversified across real assets, regions, and currencies.
“The current situation carries many of the same characteristics, with direct threats to supply, transport routes, and pricing stability.
“Investors should be taking a clear-eyed view of their exposure—considering diversification across asset classes, sectors, and geographies, and ensuring they are not overly reliant on any single outcome.”
