The Oil Shock Isn't Over. The Risk It Exposed Remains.

The headlines this week have been hard to keep up with. An interim framework between the United States and Iran briefly reopened the Strait of Hormuz — the passage that carries close to a fifth of the world's oil — and tankers began moving again. Within days, after fighting flared in Lebanon, Iran's military announced it was closing the strait once more, and the follow-on talks meant to build toward a lasting peace were pushed back. (U.S. officials dispute that the strait is physically shut, and the next round is now expected to resume in Switzerland.) The point, for our purposes, is not to track every turn. It is that the relief is neither fast nor settled — and the episode is worth studying precisely because of how fragile it has proven.

For roughly fifteen weeks, a single waterway dictated the price of energy for the entire planet. The Strait of Hormuz is the narrow passage through which close to one-fifth of the world's crude oil normally moves. When traffic through it effectively stopped after the conflict began on February 28, the International Energy Agency described the result as the largest supply disruption in the history of oil markets. That is not a phrase the agency uses lightly.

The numbers tell the story plainly. Benchmark crude, which sat near $73 a barrel before the war, climbed to roughly $112 by early April. The national average price of gasoline, just under $3.00 a gallon when fighting started, peaked at $4.56 — a rise of about fifty percent in a matter of weeks, according to AAA. And the cost did not stay at the pump.

Serious enough that the President named the risk

How grave was the economic threat? Grave enough that the President framed the agreement, in his own words, as a way to avoid "economic catastrophe." Speaking at the G7 summit in France the day the framework was reached, Donald Trump said he did not want to preside over a depression, and reached for Herbert Hoover — the predecessor most associated with the onset of the Great Depression — as the figure he was determined not to resemble. Each time peace looked closer, he noted, the market moved up.

Set the politics aside; the economic signal is the part worth keeping. When the person with the fullest view of the situation publicly weighs a downturn serious enough to earn a Hoover comparison, it tells you how much weight a single waterway was bearing — and how exposed the wider economy had become to one chokepoint half a world away.

The shock landed where it always lands first

Energy is woven into nearly everything — not only what it costs to drive, but what it costs to move food from the farm to the shelf, to run a factory, to ship a package. So when crude spiked, the effect spread. Headline inflation, which had eased to 2.4 percent in February, jumped to 3.3 percent in March, its highest reading since the spring of 2024, with the monthly increase the steepest since 2022. The figures come from the Bureau of Labor Statistics.

Economists at the Federal Reserve Bank of Dallas estimated that even under a relatively benign scenario — the strait closed for a single quarter, then reopening gradually — the shock would add roughly six-tenths of a percentage point to headline inflation for the year. Moody's Analytics put the cumulative cost to American consumers and taxpayers at around $132 billion, and counting.

For a working household, a spike like this is painful and absorbable. Wages, eventually, tend to follow prices up. But for a retiree, the arithmetic is different, and that difference is the heart of what this episode should teach us.

A thinner cushion for the next one

The reason the pain at the pump was not worse is that the government spent down its emergency stockpile to soften it. The Strategic Petroleum Reserve — the nation's buffer against exactly this kind of supply shock — fell to 340.3 million barrels by mid-June, according to Energy Information Administration data. That is the lowest level since 1983, when the reserve was still being filled for the first time and the American economy was a fraction of its current size.

Since the war began, the reserve has drawn down by roughly 75 million barrels, about eighteen percent of its volume, as part of a coordinated international release — the largest such intervention the IEA has ever organized. The buffer did its job. But a buffer that has been drawn down is, by definition, a smaller buffer the next time something goes wrong. That is the quieter danger here: not the shock that just happened, but the diminished capacity to absorb the one that hasn't.

"Reopened" is not the same as "back to normal"

Here is the part of the story most worth understanding, because it runs against intuition. The announcement that the strait is reopening does not mean oil is flowing freely again, and it does not mean prices snap back tomorrow. Several constraints stand between a signed document and a normalized market.

Mines are the first. Clearing a contested waterway is painstaking, slow work; in late April the Pentagon reportedly told Congress that fully clearing the strait could take up to six months. As of this week, the independent tanker association Intertanko reported that roughly eighty mines still sat in the strait's main shipping lane, leaving the primary route effectively closed even during the brief reopening. Insurance is the second. The marine underwriting market does not lift a war-risk designation on the strength of a diplomatic announcement — it waits for a sustained record of safe, incident-free passage before premiums fall, and until they do, many operators simply will not send a tanker worth several hundred million dollars through the lane. One fleet manager noted that his vessels would wait for a full month of clean transits before moving, not a mere few days.

Then there is sheer distance: even once loading resumes, a cargo leaving the Gulf takes weeks to reach a refinery and longer still to become fuel in a tank. The realistic path is a cautious resumption first, then gradual clearance, then a slow return of mainstream shipping as insurers relent — with the actual relief at the pump arriving weeks to months later, assuming nothing goes wrong in between.

A ceasefire can be announced in an afternoon. A supply chain heals on its own schedule.

What an episode like this asks of a plan

It is tempting, watching all this, to want to do something dramatic — to predict the next shock and position around it. That is almost always a mistake. No one rang a bell on February 28, and no one will ring one before the next disruption either. The goal is not to forecast the unforecastable. It is to build a plan sturdy enough that you don't need to.

Three implications stand out for the households we work with. The first is sequence-of-returns risk. A retiree drawing income from a portfolio during a sharp drawdown is selling assets into weakness, locking in losses that a still-working investor would simply ride through. A war-driven oil shock is exactly the kind of event that can produce that drawdown at an inconvenient moment, which is why a cash-and-bond reserve that lets you avoid selling stocks in a bad stretch is not timidity — it is the mechanism that makes the rest of the plan work.

The second is the purchasing-power problem we've already named. A fixed pension with no cost-of-living adjustment is wonderfully stable in dollars and quietly vulnerable in what those dollars buy. The answer is not to fear it but to plan around it — to pair it with assets that have a chance of growing faster than prices over decades, so the whole picture keeps pace even when one piece doesn't.

The third is concentration. Many of the families we serve hold a meaningful position in a single utility or energy-adjacent employer's stock. An energy shock can cut in surprising directions for such companies, helping some lines of business and hurting others. A position that represents a large share of a household's net worth deserves a deliberate decision, not a default.

Closer to home, and happening now

This is not only history, and it is not only an abstraction. The company at the center of so many plans here is, at this very moment, making the largest capital commitment in its modern history — and the Iran shock reaches into it directly.

Driven by a surge of data-center and artificial-intelligence demand across the Southeast, Southern Company has raised its five-year capital plan to roughly $81 billion, with about half of that going to new power generation — up from $48 billion as recently as late 2024. Georgia Power alone has proposed some $16 billion to add roughly 10 gigawatts of new capacity, the majority of it natural gas. By any measure it is one of the largest build-outs in the company's history, and the bet runs heavily through a single fuel.

Two of those forces matter most. The first is the fuel itself. The same closure of the Strait of Hormuz that moved oil also struck natural gas: roughly a fifth of the world's liquefied natural gas normally passes through that strait, mostly from Qatar, and Asian and European gas benchmarks spiked by roughly 60 to 90 percent in the weeks after the war began. The American market was largely spared this time — abundant domestic shale held the U.S. benchmark to a single-digit rise — but that cushion is thinning as the country ships more of its gas onto the world market each year. A company placing a multi-decade, multi-billion-dollar bet on gas is, in effect, deepening its exposure to a fuel whose geopolitical vulnerability was just put on vivid display.

The second force is the cost of money, and it is the more immediate one. An $81 billion plan is financed largely with debt, and the same inflation the Iran shock revived — the jump back above three percent we noted earlier — is what keeps borrowing costs from falling. Southern Company names the danger plainly in its own filings, flagging the “capital access and revenue recovery risks” that come with funding so much new construction. The larger the build, the more a stretch of high rates compounds its cost — and this build is the largest the company has ever attempted.

A third pressure ties the first two together: affordability. A build-out already projected to lift monthly bills, layered on top of any fuel costs passed through to customers, sharpens the question of how much of this investment regulators will ultimately allow the company to recover — and how customers, and voters, respond. None of this is a prediction that Southern Company stumbles. The demand is real, the contracts are long, and the company is well run. It is, rather, a reminder that even a strong, essential enterprise has its fortunes shaped by forces it does not control — energy prices and interest rates chief among them — and never more so than in the middle of a commitment this size.

Which brings the point home. For a household whose net worth leans heavily on Southern Company stock, that exposure is not abstract: the same external shock now moving through fuel costs and borrowing rates is the shock that shapes the value of the very holding. Believing in the company — even having given it a career — is not the same thing as wanting your retirement to rise and fall with it. The prudent response is not to predict how the bet turns out. It is to make sure that no single holding, however trusted, carries more weight in your plan than it can safely bear.

An interim framework is good news, and a strait that reopens is better news still. But a passage that opened and then, within days, was declared shut again is a vivid reminder that the path from a ceasefire to a settled peace is neither short nor straight — and the lesson the episode leaves is durable: the systems we rely on are more fragile, and recover more slowly, than a headline suggests. A retirement plan does not need to predict the next strait to close. It needs to be built so that when one does, you can wait it out.
