Mortgage applications in the United States fell 4.2% in the week ending 2 October 2026, according to the Weekly Mortgage Applications Survey that the Mortgage Bankers Association (MBA) released on Wednesday 7 October. The figure is seasonally adjusted and compares the week with the one before it. Without the adjustment, the association's Market Composite Index was down 4%.

A day later, on Thursday 8 October, the trade publication HousingWire reported a second MBA measure. The association's Mortgage Credit Availability Index fell 0.2% in September, to 107.1. The two numbers describe different sides of the same market: one counts the borrowers who asked for a loan, the other tracks how readily lenders were prepared to grant one. In early October both moved down, the first sharply and the second only a little.

For agents, loan officers and anyone with a sale waiting on finance, the weekly survey is the more immediate of the two. It also carries the detail that explains the fall: the average contract rate on the conforming 30-year fixed loan rose to 7.49%, which the MBA's Joel Kan described as the highest level in almost three years.

Mortgage Bankers Association: Weekly Mortgage Applications Survey for the week ending 2 October 2026, and the September 2026 Mortgage Credit Availability Index as reported by HousingWire.

A second weekly fall in a row

The decline did not arrive alone. Axios reported on 1 October that applications had fallen 6% in the previous survey week, the one that ended on 25 September. Set side by side, the two readings give a drop of 6% followed by a drop of 4.2%. Applied one after the other, those two falls would leave the volume of applications roughly 10% below where it stood a fortnight earlier, although that sum is this magazine's arithmetic and not a figure the association has published, and the Axios report does not say which version of the index its 6% refers to.

The MBA measures applications against a fixed starting point: its index is set at 100 at 16 March 1990. The association's NewsLink article on the latest survey gives the weekly percentage changes but not the level of the index itself, so the release says how fast activity is moving and not how it compares with earlier years in absolute terms. What it does give is a year-on-year comparison for each of the two main kinds of application, and those comparisons are where the gap between buyers and existing owners shows most clearly.

Refinancing takes the larger hit

The survey splits applications into two groups: loans to buy a home, and loans to replace an existing mortgage. They did not fall by the same amount.

The Refinance Index dropped 8% from the previous week and stood 56% below the same week one year earlier. The seasonally adjusted Purchase Index fell 2% on the week. The unadjusted Purchase Index also fell 2%, and was 15% lower than in the same week of 2025.

So refinancing fell four times as fast as purchase applications over the week, and its annual decline was close to four times as deep. Kan, who is the MBA's vice president and deputy chief economist, said in the release that very few homeowners have an incentive to refinance at current rates. The survey's own breakdown bears that out: refinancing made up 37.0% of all applications, down from 38.3% a week earlier, a loss of 1.3 percentage points in seven days.

Purchase demand looks steadier week to week, but the annual comparison has slipped. HousingWire reported on 3 October that purchase applications in the previous survey week were down 4% on the week and 14% on the year. The latest reading puts the weekly fall at a smaller 2% and the annual gap at a slightly wider 15%. In other words, the pace of the weekly decline halved, yet purchase applications ended the week further below their level of a year earlier than they had been seven days before.

Within purchase lending, one segment stood out. Applications for purchase loans backed by the Federal Housing Administration (FHA) fell 6%, which the MBA said was the largest decline of any loan type.

What borrowers were quoted

The rates in the survey are average contract rates. The MBA reports them by loan type, together with the points charged, and for the 30-year conforming loan it specifies a loan-to-value ratio of 80%. The dividing line between a conforming and a jumbo balance in the survey is US$832,750.

Four of the five rates rose. The largest move was on the conforming 30-year loan, up 0.19 of a percentage point in a week. The FHA rate rose 0.17 of a point and crossed 7%, the 15-year rate rose 0.15 and the jumbo rate 0.12. Because the conforming rate climbed faster than the jumbo rate, the gap between them widened from 0.03 of a point to 0.10, with the larger loans still the cheaper of the two.

The 5/1 adjustable-rate mortgage (ARM) was the exception: its contract rate eased by 0.04 of a point. That left it 1.06 points below the conforming 30-year rate, compared with 0.83 points a week earlier. The headline rate is not the whole price, however. Points on the ARM rose from 1.20 to 1.69, by far the largest change in points of any loan in the survey, and the MBA said effective rates rose for all loan types, the ARM included.

Points moved up elsewhere too: from 0.75 to 0.84 on the conforming loan, from 1.18 to 1.36 on FHA loans, from 1.02 to 1.05 on the 15-year loan and from 0.50 to 0.52 on jumbo balances. A borrower comparing two weeks of quotes would therefore have seen a higher rate and a higher upfront charge on every fixed-rate product in the table.

How the mix of applications shifted

Besides the indexes and the rates, the survey reports what share of all applications each kind of loan represents. These shares overlap, since a single application can be both a refinance and a government-backed loan, so they are not parts of one total.

The movements behind the chart were small, apart from the refinance share already described. The FHA share slipped from 16.7%, a fall of 0.3 of a point that fits with the 6% drop in FHA purchase applications. The share of loans backed by the Department of Veterans Affairs (VA) edged down from 11.9%. The share for the Department of Agriculture's programme (USDA) did not change.

Nor did the adjustable-rate share, which held at 10.3%. That is worth a second look, because Kan said in the release that a higher share of borrowers are opting for ARMs to lower their initial payments. The two statements are not in conflict: the weekly share was flat between the last week of September and the first days of October, while Kan's remark describes a movement the single weekly comparison does not capture. The release as reported does not give the earlier ARM share he was comparing with, so the size of that shift cannot be stated here.

Credit availability edges down in September

The second MBA measure looks at lenders, not applicants. HousingWire reported on 8 October that the Mortgage Credit Availability Index fell 0.2% in September to 107.1. The index is benchmarked to 100 in March 2012, so the September reading sits 7.1% above that starting point.

The components did not all move together, according to the HousingWire report. The Conventional index decreased 0.4%, the largest change of the four. The Jumbo index declined 0.3%, its second monthly decrease in a row. The Conforming index fell 0.2%. The Government index was unchanged.

Kan described the overall move as a slight decrease, and attributed it to lenders tightening documentation requirements on conventional loans. That matches the pattern in the components: the Conventional, Conforming and Jumbo indexes all fell, while the Government index held still.

One caution about the source. The association's own release on the index was not among the pages this article could draw on; the figures come from HousingWire's report, which carries an automation byline and states that it was generated with artificial intelligence and reviewed by an editor.

Another gauge points the same way

HousingWire's coverage of the weekly survey, published on 7 October, set the MBA figures beside a separate measure from the company Xactus. Its Mortgage Intent Index fell 5.69% week over week to 102.7. Thomas Lloyd, the chief strategy officer of Xactus, linked the decline to elevated mortgage rates weighing on borrower activity, HousingWire reported.

The two series are built by different organisations and are not interchangeable, and the Xactus figure is a company's own index, not an official statistic. But they agree on direction: both recorded fewer households moving towards a mortgage in the same week, by 4.2% on the MBA's count and by 5.69% on the Xactus one.

What the figures do and do not show

Taken together, the week's releases describe a market in which the cost of borrowing rose quickly and demand fell with it, while the supply of credit barely changed. A 0.2% fall in an index that stands at 107.1 is a small adjustment beside an 8% weekly fall in refinance applications. On these numbers, the early-October slowdown is a story about what loans cost far more than one about lenders closing the door.

There are limits to what can be read from them. An application is a request, not a completed loan, and the survey as reported says nothing about how many of the week's applications will reach closing. The percentage changes are national averages, with no breakdown by state or city in the material published. The index levels were not given, so the size of the market in absolute terms is not something this release settles. And the two MBA measures cover different periods: the applications survey a single week ending on a Friday in October, the credit index the whole month of September.

Both are regular series. The applications survey is published weekly and the credit availability index monthly, so each will be updated on that rhythm. What the next readings will show is not something the sources predict, and neither does this article.
