Mortgage Rates Fall to One-Week Lows After Trump Cancels Iran Strikes

US mortgage rates fell to a one-week low on Thursday after President Trump cancelled a fresh round of strikes on Iran and said both sides had approved final details of a permanent ceasefire, ending a session that had begun with inflation and war headlines pushing yields higher. The average 30-year fixed rate landed at 6.60%, down 0.07 percentage points on the day, the lowest level for the average lender since last Thursday.

Mortgage lenders normally set rates once a day and rarely change them mid-session. Thursday’s bond market move on the ceasefire news was large enough to push the bulk of lenders into a friendly mid-day reprice, leaving the average borrower with the lowest rate sheet in a week. The pattern on June 11: the war in Iran, not the morning’s inflation data, was the force moving the US housing market.

The Day’s Pivot at 1:30 PM

Mortgage rates opened the session in uneventful fashion, with the average lender right in line with yesterday’s latest levels, per the June 11 mortgage rate report. Higher producer-price inflation in the morning’s economic data and discouraging war-related headlines put upward pressure on bond yields. The bulk of the morning remained uneventful. That changed abruptly at the 1:30 p.m. inflection point, Eastern time, when news circulated that Trump had cancelled the day’s planned air strikes and said both sides had approved final details of a permanent ceasefire.

Markets moved in seconds. Stocks rallied, oil fell, and bond yields dropped, pulling mortgage rates lower with them.

The size of the move was unusual. Within a few hours, the bulk of US mortgage lenders had revised their daily rate sheets lower, a step most take only once per day. By the close, the average lender’s rate sat at its lowest level since last Thursday, per the same daily report.

We just made a great settlement of the war with Iran. We’re going to be subject to finalisation of documents. It should get done over the next few days.

Trump told reporters in the Oval Office on Thursday afternoon, hours after cancelling the day’s planned air strikes on Iran. The remarks were carried alongside the Kharg Island threat report Trump had posted hours earlier.

Why Geopolitical News Moved US Mortgage Rates

US mortgage rates follow the 10-year Treasury yield more closely than any other benchmark, and the 10-year moves on the same inputs as oil, equities, and the dollar. On June 11, the war in Iran sat at the top of that input list, above the morning’s inflation data in the bond market’s hierarchy of concerns. The mechanism runs through oil. Iran has choked shipping through the Strait of Hormuz for months, an action wire services reported had “crimped global energy supplies” and pushed fuel prices higher well beyond the region. When ceasefire news breaks, the bond market reads it as a near-term path to lower energy prices, a near-term path to lower inflation, and a near-term path to a less restrictive Federal Reserve. Yields fall, and mortgage rates follow.

The 10-year Treasury yield closed at 4.448% on June 11, down 0.107 percentage points, a meaningful one-day drop in a market where weeks often pass without a 10-basis-point move. The reaction was broad: Brent crude fell 4.75% to below $90 a barrel, per the live account of the oil price slide, and the major US stock indices closed up across the board. The Dow Jones finished up 1.86%, the S&P 500 up 1.75%, and the Nasdaq up 2.54%.

The 30-year fixed rate now sits in the same band it did at the start of the year, but the path it took to get there has been shaped as much by the Iran war and oil as by the Federal Reserve. The pattern shows up in the Treasury market itself: foreign holders trimmed their exposure in March as the war moved from headline risk to portfolio risk. Per March’s $41 billion China Treasury sale, that was a defensive move against the same oil-driven inflation pressure the bond market is now pricing in reverse. A ceasefire is the flip side of that trade, with lower oil, lower inflation pressure, and a slightly easier ride for the 10-year.

Hotter Inflation Was Pushing Rates Up Before the News

The ceasefire news didn’t land in a vacuum. For most of the morning, the bond market was bracing for a hotter inflation print and more war headlines, both of which would have pushed yields higher. The Producer Price Index for May, released at 8:30 a.m., came in at 1.1% headline PPI month-over-month, well above the 0.7% forecast.

The core PPI reading was 0.4%, down from 0.7% the prior month, a softer read that the bond market treated as energy-driven headline noise rather than a broader inflation reacceleration, with energy and goods inflation running higher than they have been in the post-pandemic period. The morning bond market commentary laid out the tension directly: Trump comments on the Iran war had pushed oil and yields higher in the eight minutes before the PPI data, and the hot headline added fuel. By the time the ceasefire news hit, the day’s direction had been set by the data, then overturned by the news, per the morning bond market wrap on the PPI release.

The Mid-Day Reset Most Lenders Made

US mortgage lenders prefer to set rates once per day, usually in the morning, and they rarely revisit the decision before the next session. June 11 was one of those rare sessions where the bond market moved enough mid-day to force a reset. The move after 1:30 p.m. was “easily big enough,” per the daily mortgage rate report, and the bulk of lenders issued friendly revisions to their rate sheets in short order.

That is a smaller disruption than it sounds, but it is also a useful signal. A mid-day reprice happens when the bond market breaks an internal threshold lenders use to protect their rate sheets, often tied to a meaningful move in MBS prices.

June 11 cleared that threshold by a wide margin. The UMBS 30-year 5.0 coupon, the most-traded mortgage bond, closed up 0.62 in price, per the same daily report. The move left most borrowers quoted a friendlier rate than they woke up to. The 10-year Treasury yield dropped 10.7 basis points in the same session, the kind of one-day move that resets the mortgage rate conversation for the next several days.

Where Rates Sit Now and How to Read Them

The June 11 close left the average lender quoting 6.60% on the 30-year fixed and 6.15% on the 15-year fixed, per the daily mortgage rate report. The 10-year Treasury yield closed at 4.448%, and the UMBS 30-year 5.0 bond closed at 98.16 in price, up 0.62 on the day.

The day’s drop was led by the 10-year Treasury yield, which fell nearly 11 basis points; the 30-year fixed followed with a 7-basis-point move, per the same daily report. The 15-year fixed, which tracks shorter-dated yields more closely, fell by less, consistent with the bond market pricing the move as a longer-dated repricing rather than a broad shift in Fed expectations. The Freddie Mac weekly survey, released the same day, put the 30-year fixed at 6.52% for the week ending June 11, up from 6.48% the prior week, a wider lens that captures the trend before and after Thursday’s session, per the latest weekly mortgage rate survey. The Freddie Mac number is a weekly average and runs behind the daily lender figure, which is why the two diverge by 8 basis points on the same day.

The Iranian Caveat to the Ceasefire

Nothing has been finalised.

Iran’s Foreign Ministry spokesperson Esmail Baghaei told Iranian state television on Thursday evening, accusing the US of making “excessive demands” and adding “new requests” to the negotiations, per the same live account. The majority of the text had been “finalised,” Baghaei said, but the US was causing “turbulence” in the process.

Iran’s parliamentary speaker, Mohammad Bagher Qalibaf, had earlier warned that “wrong strategies and impulsive decisions” would wreak havoc on energy markets and “create an endless quagmire.” Iran’s Foreign Ministry separately said the US attacks had “effectively rendered the ceasefire … meaningless,” without saying it was abandoning it.

The 10-year Treasury market and the mortgage lenders who follow it priced the US version of the story on June 11. The next market-moving event is the signing itself, with the US naval blockade of the Strait of Hormuz set to be lifted “immediately upon signing,” per Trump’s Oval Office remarks. Iran hasn’t confirmed the same timeline.

Frequently Asked Questions

What happened to mortgage rates on June 11, 2026?

President Trump cancelled a new round of air strikes on Iran on June 11 and said both sides had approved final details of a permanent ceasefire, a development that pushed the average 30-year fixed mortgage rate down 0.07 percentage points to 6.60%, its lowest level in a week. The drop was the largest single-session move lower in a week, per the same daily report.

Why did mortgage lenders change rates in the middle of the day?

Lenders usually lock in mortgage rates once per morning, but the bond market’s move on the June 11 ceasefire news was large enough to force the bulk of them into a second rate-sheet revision the same day. The benchmark UMBS 30-year 5.0 mortgage bond finished up 0.62 in price, per the same daily report. A vast majority of lenders made friendly revisions to their rate sheets in short order, the report noted.

What is the current 30-year mortgage rate?

Two benchmarks are useful: the Mortgage News Daily average lender figure, which updates throughout the day, closed June 11 at 6.60% on the 30-year fixed, while Freddie Mac’s weekly survey averaged 6.52% for the week ending June 11, up 4 basis points from the prior week. The two diverge because they answer different questions; the MND number is a daily snapshot, the Freddie Mac number is a weekly average. The 15-year fixed was 6.15%, down 0.05 percentage points on the day, per the same daily report. The 10-year Treasury yield closed at 4.448%, down 0.107 percentage points.

Will the rate drop hold?

The June 11 rate move is the bond market pricing in a US-Iran ceasefire, not a finalised agreement. Trump told reporters a deal “may” be signed this weekend, possibly in Europe; Iran’s Foreign Ministry spokesperson said the same evening that the deal is not yet finalised and that the US is making “excessive demands,” leaving the rate drop exposed to any news that hardens the Iranian position.

Is now a good time to lock a mortgage rate?

Locking decisions depend on a borrower’s timeline, the rate at offer, and the news cycle. A 7-basis-point move in a single session is meaningful, but the move rests on a ceasefire that Iran hasn’t confirmed, so the rate drop is contingent rather than structural. Any individual mortgage quote depends on credit score, loan size, property type, down payment, and lender; the average figures cited in this article are benchmarks, not offers.
