Last week I wrote that the easy market was over. That prices were falling, inventory was rising, and the Fed had threatened to make it worse. I did not expect to be back this week with an even harder message.
Yesterday, President Trump declared the Iran ceasefire “over.” US forces struck Kharg Island — Iran’s primary oil export hub. Oil prices spiked more than 5% within hours. Brent crude briefly topped $97 per barrel. The EU Aviation Safety Agency told airlines to avoid the airspace of Iran, Iraq, and Lebanon through August 31. The Strait of Hormuz, which had been partially reopened under the June memorandum of understanding, is now effectively closed again to Western-allied commercial shipping, with Lloyd’s List Intelligence reporting no Western-allied transits since early May.
This is not background noise for the real estate market. It is a direct input. And if you are a buyer or seller in Boston or on Cape Cod, you need to understand why.
What the Iran War Has Already Done to the Economy
The conflict that began on February 28 — when US and Israeli forces launched Operation Epic Fury and killed Supreme Leader Khamenei — has already produced what analysts are describing as the largest supply disruption of the global oil market in history. Energy prices surged. Inflation, which had been slowly retreating toward the Fed’s 2% target, reversed course and accelerated. CPI hit 4.2% in May. PCE hit 3.8% in April. Consumer confidence — already under pressure from tariffs and federal job restructuring — collapsed to its lowest level in seventy years.
Every one of those data points flows directly into the housing market. Elevated energy prices feed through to construction costs, transportation, and household budgets. Compressed household budgets mean less purchasing power for buyers. Collapsed consumer confidence means buyers who have the means to purchase are choosing to wait. And an inflation environment that forces the Fed to hold — or raise — rates means the mortgage rate relief that buyers have been counting on is not coming.
That was the situation last week, when the ceasefire was nominally holding. This week, the ceasefire is over.
What Yesterday’s Escalation Changes
The June memorandum of understanding had given markets something they desperately needed: a plausible path toward lower energy prices. If the Strait of Hormuz fully reopened, oil supply would normalize, energy prices would ease, inflation would decelerate, and the Fed would have the cover it needs to at least stop threatening hikes. That scenario is now off the table — at least temporarily.
What replaced it yesterday is the worst possible combination for consumer confidence: active military escalation, oil prices spiking toward $100 per barrel, closed shipping lanes, and a president who said the deal is over before walking it back slightly the following morning. Trump’s statement that the recent fighting “would not lead to long-term military action” provided some relief — markets partially recovered — but the damage to confidence is real, and it will not be repaired overnight.
The IRGC’s “Persian Gulf Strait Authority” is now actively collecting fees of up to $2 million per vessel on ships transiting the Strait, payable in Chinese yuan, Bitcoin, or USDT. That is not a ceasefire. That is a fee-based blockade. And a fee-based blockade means elevated energy prices are not a temporary spike — they are becoming a structural feature of the global economy.
Why This Hits Consumer Confidence So Hard
I wrote last week about the OECD Composite Consumer Confidence Index sitting below 48 — lower than COVID, lower than the 2022 inflation shock, lower than any reading in recent history. The reason that number is so extreme, and so different from previous downturns, is that consumers cannot identify a clear end point.
During COVID, the source of anxiety was specific, and the response was massive and immediate. During the 2022 inflation shock, the Fed raised rates aggressively, and the market understood the mechanism by which it would bring inflation down. Today, consumers are facing a war with no clear resolution timeline, an inflation problem driven in part by geopolitical factors the Fed cannot control, a new Fed chair who has signaled he will not blink, and a trade environment that remains unpredictable.
Yesterday’s escalation adds another layer of uncertainty to an already fragile psychological environment. When people cannot see a clear path to stability — when the news each morning brings a new variable they cannot plan around — they do not make large, long-term financial commitments. They wait.
The housing market is the most direct casualty of that waiting.
What This Means for Mortgage Rates
Here is the mechanism that connects Kharg Island to your monthly mortgage payment.
Oil prices drive energy costs. Energy costs drive inflation. Inflation drives bond yields. Bond yields drive mortgage rates. Yesterday’s spike in oil prices — Brent crude above $97, a 5% single-day move — is not yet reflected in mortgage rates because bond markets are still processing whether this is a temporary escalation or a sustained return to active conflict. But if oil holds above $90 and the Strait remains functionally closed, the disinflationary trend that had been quietly supporting a modest decline in bond yields reverses.
The 30-year fixed mortgage rate was sitting at 6.52% going into this week. The scenario where that number declines meaningfully in the second half of 2026 — which many buyers had been counting on — just got materially less likely. The scenario in which Warsh’s nine hawkish Fed officials make good on their rate-hike projection just got materially more likely.
What This Means for Cape Cod and Boston Right Now
I want to be direct with you about what I am seeing on the ground because aggregate data always lags lived experience by several weeks.
The buyers I am working with are not panicking. But they are recalibrating. The buyers who were close to a decision last month are asking more questions. The buyers who were already cautious are pulling back further. The buyers who were waiting for a signal that conditions were improving just got the opposite signal.
On Cape Cod, where the entire market is discretionary — nobody has to buy a vacation home — the psychological environment matters more than anywhere else. A buyer from Wellesley or Newton who was considering a summer property purchase does not need any specific news to decide to wait. They need a sense that the world is stable enough to make a large, long-term financial commitment with confidence. Right now, they do not have that sense. And yesterday made it worse.
In Boston, the necessity-driven segment of the market — corporate relocations, life transitions, career moves — continues to function. Those buyers move because they have to. But the discretionary luxury buyer, the move-up buyer, the buyer who could buy now or wait another year — that buyer is recalibrating.
For sellers, the implication is the same as last week, but sharper. The buyers who are in the market right now are more deliberate, more data-driven, and more willing to walk away than any buyer pool I have seen in my career. A property priced for 2024 is unlikely to find a 2026 buyer. The adjustment is not optional. It is arithmetic.
The Longer View — And Why It Still Matters
I am not going to end this article without saying something I believe is true even in difficult moments: the long-term case for owning real estate in Boston and on Cape Cod has not changed.
Wars end. Straits reopen. Inflation cycles resolve. Consumer confidence recovers. The structural supply constraints that make Boston and Cape Cod real estate valuable — the finite land, the desirable communities, the proximity to one of the great economic engines on the East Coast — do not change because oil spiked yesterday.
What changes is the timeline and the price. The buyers who move through this period with patience, precision, and a clear-eyed understanding of the actual conditions will position themselves well for the recovery that will eventually follow. The sellers who adjust their expectations to match today’s reality — rather than waiting for yesterday’s conditions to return — will transact. The sellers who hold out for a market that has changed will wait a long time.
The easy market is over. The smart market — for both buyers and sellers — is the one that operates clearly within the existing market.
That is the only market available right now. And we navigate it well every day.
