Mastery of energy, again

Winston Churchill, as first lord of the Admiralty, tied Britain’s fate to Persian oil. United States President Donald Trump’s war in Iran, centred on Operation Epic Fury, could do the same for the West by removing Iran’s nuclear shadow, resetting oil toward US$60, and finally unlocking a modern peace dividend.

“Mastery itself was the prize of the venture.” Winston Churchill’s 1912–13 case for converting the Royal Navy from coal to oil—enshrined in historian Daniel Yergin’s The Prize: The Epic Quest for Oil, Money, and Power captured the brutal clarity of a great power energy strategy: accept dependence to command the seas. That wager framed the last century. In 2026, as Epic Fury grinds through the Gulf and Brent trades above US$100, the question is no longer whether oil confers mastery, but who holds it: a revolutionary theocracy astride the Strait of Hormuz, or a West intent on stripping the terror and nuclear risk now priced into every barrel out of the energy system—finally collecting a long‑deferred peace dividend.

Churchill’s shift bound Britain’s prosperity to distant wells and narrow waterways, welding energy supply to national survival. He understood that control of energy was not an adjunct to power, it was the metric. In April 2026, with Hormuz contested and Iranian missiles demonstrating reach beyond the Middle East, the same dilemma confronts policymakers and markets. Does the West still want that prize, and what is it prepared to stake to reclaim it from a regime that has spent half a century turning oil, terror, and nuclear brinkmanship into interchangeable tools of coercion? Assume Trump’s campaign does what it is now on course to do: not merely reopen a chokepoint, but neutralize a nascent tactical nuclear threat which, left intact, would hardwire a doomsday premium into global energy prices for a generation.

Iran’s war with the West has done what decades of shocks, embargoes, and “maximum pressure” could not: it has made the hidden tax on energy legible even on a Bloomberg screen. Strip out the terror and nuclear‑risk premiums in a post‑Trump‑Iran settlement, and Brent does not belong north of US$100; it sits much closer to the US$60 level implied by underlying supply and demand and pre‑war bank research. The gap between where oil trades in a world held hostage by a nuclear‑ambitious theocracy at Hormuz and where it would trade if flows were secure and de‑weaponized is more than a volatility surface. It is the unclaimed peace dividend of globalization, the energy market analogue of the windfall that followed the end of the Cold War, when the removal of an existential nuclear standoff released capital, confidence, and capacity back into the real economy.

The choice now facing the West is whether to lock in that outcome. Ending the Cold War removed the Sword of Damocles that had hung over every investment decision for half a century; a successful conclusion to Iran’s nuclear extortion would do something similar for the 21st‑century economy, collapsing a structural risk premium that has quietly taxed households, corporates, and sovereigns alike. The question, as Churchill would have recognized, is whether the West is prepared not just to win on the battlefield but to consolidate that victory into a new era of energy mastery, and to treat the potential verified removal of Iran’s enriched stockpile and fuel‑cycle capabilities as a security gain on the scale of the 1987 Intermediate-Range Nuclear Forces Treaty or the dissolution of the Soviet arsenal.

For Europe, the stakes are not abstract. Iranian missiles and drones have already shown that European Union territory and NATO logistics hubs sit uncomfortably close to the new strike envelope, shattering the illusion that Gulf risk could be quarantined to energy prices alone. The deeper reckoning is with Europe’s own energy strategy. The choice by many Western governments to anchor industrial policy primarily on climate targets while neglecting cheap and secure supply—is now coming home to roost. Prosperity in an artificial intelligence (AI)‑driven economy rests on abundant, reliable energy rather than on cheap consumer imports, echoing Churchill’s insight that mastery of energy is mastery of power. That logic points north as well as east: Canada with its hydrocarbons, hydropower, and critical minerals—looks less like a peripheral supplier and more like a potential resource superpower if it can cut through regulatory thickets and build the infrastructure to deliver secure barrels, electrons, and metals to allied markets.

U.S. hard power, the security backstop European, Canadian, and the United Kingdom economies long treated as a law of nature, now looks more contingent, more politically conditional, and more thinly spread across theatres. One could easily imagine Washington reverting to a post‑First World War stance, turning inward to rebuild its real economy, and no longer willing or able to offer security as a global public good. A successful Trump‑led settlement that removes both the nuclear overhang and the Hormuz chokepoint as instruments of coercion would not only stabilize Atlantic world energy supply but also underwrite a more credible NATO deterrent at lower long‑run cost—replacing the ersatz “peace dividend” of underfunded defence with a genuine one built on reduced threat rather than wishful budgeting.

For investors, a decisive outcome in Iran would not just redraw maps in the Gulf; it would refashion term premia. As the nuclear and terror discounts bleed out of the curve, gilt yields and U.S. Treasuries alike would begin to reflect lower expected inflation and slimmer risk premia rather than recurring energy shocks. Credit spreads-particularly for energy‑intensive sectors and fragile sovereigns—would compress as balance of payments and default risks ease. Equity markets would reprice in turn: structurally lower input costs and a thinner geopolitical risk layer would lift margins in manufacturing, transport, and consumer names, even as oil majors and defence stocks surrender some of their crisis rent. For the Square Mile and Wall Street, the real prize is not another trade on US$120 Brent; it is the re‑rating that comes when a structural doomsday premium is finally taken out of the system and the peace dividend—deferred since the end of the Cold War and repeatedly eroded by Iran—at last starts to be paid in cash flows rather than communiqués.

Churchill’s ghost at Hormuz

On the first day of April 2026, as Brent traded just above US$100, the world was relearning what Churchill meant when he called mastery the prize. As first lord of the Admiralty, he forced the Royal Navy off domestic coal and onto Persian oil, then secured that lifeblood by buying control of Anglo‑Persian Oil. He knew the bargain: oil conferred speed and reach, but at the price of dependence on distant fields and fragile sea lanes. Hence his warning to Parliament in 1913 that “on no one quality, on no one process, on no one country, on no one route, and on no one field must we be dependent” and his insistence that safety and certainty in oil lay “in variety, and in variety alone.”

That decision created the modern energy system and placed Iran at its centre. Four decades later, as prime minister, Churchill confronted the second act of his own gamble when Iran’s prime minister Mohammad Mossadegh nationalized Anglo‑Iranian Oil Company’s assets. The 1953 coup that restored the Shah was less a morality play than a confirmation that control over Iranian oil would be contested by empires, nationalists, and, eventually, revolutionaries. Churchill’s instinct to secure supply at the source and to dominate the sea lanes that connected it to Britain established a strategic architecture with a simple premise: mastery of energy flows was indistinguishable from mastery of global power.

The twist came in 1979, when that architecture was seized by those it had previously constrained. The Iranian Revolution toppled the Shah and installed Ayatollah Khomeini’s theocracy—a regime that viewed the U.S. as the “Great Satan,” embraced terrorism as statecraft, and sat astride the Strait of Hormuz. Oil workers struck, production collapsed, and prices more than doubled. The world discovered that the geographic fulcrum Churchill had chosen could just as easily be pulled by a revolutionary fist. From that moment, the markets began to price an Iran terror premium. It was distinct from OPEC’s cartel pricing power or conventional war risk. It recognized that a state sponsor of terrorism—with a web of proxies and control over the narrow channel through which roughly a fifth of seaborne oil must pass—would periodically weaponize that position. Each tanker attack in the 1980s “Tanker War,” each Hezbollah bombing, each missile launched at a Gulf facility added a sliver to that premium. Over time, slivers hardened into a slab.

Churchill’s maxim was inverted. Variety still existed geologically, with new barrels from the North Sea, Alaska, and deepwater, but strategically the system was again anchored on a single actor most willing to turn energy into a cudgel. Where Churchill had sought safety through variety, the world lived with uncertainty concentrated in one revolutionary capital. And where he had seen mastery as the prize of bold, deliberate ventures, mastery of energy risk quietly migrated to a regime that treated terror as an operating model.

How terror became a line item

The terror premium is no longer an academic calculation; it is a visible spread. In calmer phases of the cycle, geopolitical risk barely nudges price forecasts. In crisis, as in early 2026, the gap between pre‑war expectations for oil and the levels seen when Hormuz is threatened yawns wider, and futures curves kink as traders try to price the possibility of disruption. Even if part of that is fear and temporality, the underlying message is obvious. There is a structural surcharge on every barrel to account for the probability that Tehran or one of its proxies will, at some point, take terrorist action.

That surcharge has a history. The 1973–74 oil embargo revealed how quickly geopolitics could quadruple prices, but Iran was then still an ally. The true discontinuity came with the 1979 revolution and the Iran‑Iraq War. The Tanker War saw mines in the Gulf, neutral shipping attacked, and U.S. naval forces drawn in to reflag and escort tankers. Washington’s 1984 decision to designate Iran a state sponsor of terrorism, off the back of Hezbollah’s bombing of U.S. Marines in Beirut, made explicit what markets had intuited: one of the central suppliers to the system was also its most committed saboteur.

On April 28, 2026, Finance and National Revenue Minister François-Philippe Champagne released the 2026
Spring Economic Update (the Update). This was the first spring economic update after the federal budget was
moved to the fall in 2025. In the absence of a federal budget earlier this year and with the recent shift to a
majority government, Canadians have been awaiting clear direction on the federal government’s policy
focus and anticipated initiatives. Overall, the Update introduces relatively little that had not been previously
announced, while showing an improved fiscal outlook, with the projected deficit declining despite $37.5 billion
in net new spending.
