The new home affordability crisis is showing signs of ending for the first time in nearly three-and-a-half years. The median sale price of a new home sold in the United States has dropped below the upper threshold of affordability that determines whether the typical American household can afford the monthly mortgage payment on the typical new home sold in the U.S.

That threshold is defined by having a mortgage payment that represents no more than 36% of household income, which lenders have historically used to determine whether they will loan money to a household that has no other debt. For October 2025, a household earning the median household income would that bought a new home at the month's median sale price of $392,300 would see their mortgage payment consume 34% of their monthly household income, which puts the typical new home within affordable reach.

For households that do carry other debt, lenders prefer their monthly mortgage payments consume no more than 28% of their pre-tax household income to ensure they have financial resilience to deal with unexpected expenses when their mortgage payments fall below these affordability thresholds. At 34% of its monthly household income, the median new home sold in October 2025 would be affordable for median income-earning households that carry low levels of other debt, the first time that's even been possible since March 2022.

The latest update of our chart tracks the changing relative affordability of the typical new home sold in the U.S. is for the typical American household with respect to the mortgage lending industry's key affordability thresholds from January 2000 through October 2025.

Mortgage Payment for a Median New Home as a Percentage of Median Household Income, January 2000 - October 2025

The National Association of Realtors explains the main factor why new homes have suddenly dropped into the range of affordability:

Prices for newly built homes fell to a four-year low in the fall as builders cut prices, according to a report delayed by the government shutdown.

The median sales price for new homes that went under contract in October was $392,300, down 8% from a year earlier and the lowest level since 2021, the U.S. Census Bureau reported on Tuesday.

New-home prices have been trending down since late 2022, after the affordability crisis priced many potential buyers out of the market. Homebuilders responded by cutting prices and boosting incentives.

This month, 40% of builders reported cutting prices, while 67% reported using sales incentives such as mortgage rate buydowns, according to the leading survey of homebuilder sentiment.

Meanwhile, sales of new homes improved year-over-year as mortgage rates were also lower on average in October 2025, contributing to the improved affordability of new homes for the typical American household:

Sales of new single-family houses were at a seasonally-adjusted annual rate of 737,000 in October, little changed from the prior month but up 19% from a year earlier.

Transactions rose as falling mortgage rates and prices both contributed to making new homes more affordable for prospective homebuyers.

Mortgage rates averaged 6.25% in October, down from 6.43% in October 2024, according to Freddie Mac.

The average price of a new home sold in October 2025 was $498,000, which was three percent higher than September 2025's average sale price of $483,500.

Looking at what that means for new home builders, we find time-shifted (centered) trailing twelve month average of the total value of new homes sold in the United States is $29.11 billion. We find the lower sale prices of new homes is contributing to an upward trend in the number of sales, but we find the average sale price of a new home is relatively stable, or flat.

The following charts present the U.S. new home market capitalization, the number of new home sales, and their sale prices as measured by their time-shifted, trailing twelve month averages from January 1976 through October 2025.

Following up our coverage of August 2025's potential statistical fluke increase in the number of new home sales, revisions to the sales data released on 13 January 2026 confirms the August 2025 sales figures were indeed a fluke.

Trade between the U.S. and China has been almost fully cut in half since its October 2021 peak. The latest available trade data for October 2025 reveals the combined value of all goods exchanged between the two nations stood at $32.8 billion, which compares with the record peak of $64.7 billion in October 2021.

October is a significant month for U.S.-China trade because U.S. exports of soybeans to China typically peak during the month. In 2025 however, even though China has been buying U.S. soybeans, sales have been muted with the result exports have significantly lagged the typical seasonal boost seen in previous years.

That outcome is a direct consequence of the tariff war between the two nations. Part of China's trade war strategy has been to purchase soybeans from other nations, with Brazil gaining much attention from China's soybean purchasers.

The following chart shows how the combined value of trade between the U.S. and China stands through October 2025 in the context of how trade between the nations has developed since January 2017.

Combined Value of U.S. Exports to China and U.S. Imports from China, January 2017 - October 2025

The chart features a counterfactual of how the rolling twelve month average value of goods exchanged between the U.S. and China would have grown in the absence of the global tariff war between the two nations. Through October 2025, we find the gap between that counterfactual and the actual trajectory of U.S.-China trade has opened up to $11.5 billion, with a cumulative loss of $43.4 billion since February 2025.

Looking forward, the U.S. and China reached a one-year trade deal on 1 November 2025. We'll see over the next several months how that deal might change the overall trajectory of the rolling twelve month average. Assuming that deal is not disrupted by President Trump's just-announced 25% tariff on nations trading with Iran because of that nation's repressive government's crackdown against protestors.

All this discussion emphasizes a critical point. Rather than a tool to raise revenue, tariffs have become a tool for addressing geopolitical concerns during President Trump's second term. They've become more than a means of regulating trade.

The U.S. Bureau of Labor Statistics released its employment situation data through December 2025, resuming their regular reporting schedule after the delays caused by 2025's Senate Democrats' government shutdown fiasco.

The jobs data was mixed for working U.S. teens. Older teens, Age 18-19, saw their numbers among the ranks of the employed rise in December 2025. With a seasonally-adjusted 3,547,000 older teens earning wages, the percentage of the older teen population rebounded to 42.9%.

Unfortunately, younger teens, Age 16-17, saw their numbers fall again, dropping to a seasonally adjusted 1,938,000 and continuing a multi-year, long-running trend. That downward trend is most evident when looking at the share of the younger teen population with jobs. The employment-to-population statistic for this demographic dropped to 20.3%, its lowest level since January 2021's 20.4%.

The following chart visualizes these trends along with the seasonally-adjusted total Age 16-19 employment level:

US Teen Employment and Employment to Population Ratio, January 2021 through December 2025

Sharp-eyed readers will catch that the number of employed Age 16-17 teens and Age 18-19 teens doesn't add up to the combined Age 16-19 figures in these charts. That's because each age demographic gets its own seasonal adjustment. If you want numbers that do add up within a small margin of error, you'll want to access the BLS' non-seasonally adjusted employment figures.

Really sharp-eyed readers will also note the seasonally adjusted data presented in the charts doesn't match our last edition in this series. The BLS revised its seasonally adjusted data with the December 2025 employment situation report, with the revisions affecting all previously reported data from January 2021 onward. The revisions do not affect the nonseasonally adjusted data, which remains unchanged from their previously reported figures.

As expected, the first full trading week of January 2026 was an exciting one for the S&P 500 (Index: SPX), which closed out the week at 6,966.28, a new record high and 1.6% higher than it ended the previous trading week.

Although we anticipated the week would be a good one for oil and gas industry stocks because the U.S.' successful extraction of Venezuela's dictator from power during the preceding weekend, there were two other big news events to push stock prices higher across the board during the week that was.

The first of those additional headlines that moved the markets originated at the annual Consumer Electronics Show in Las Vegas on Tuesday, 6 January 2025. Nelson Huang, the CEO of Nvidia (Nasdaq: NVDA) announced the company was in full production of its next generation AI-industry leading computer chips and that data storage was becoming a constraint on the sector's growth, which prompted the stocks of hard drive and memory storage to surge.

The second additional headline came on Friday, 9 January 2025 with the release of the December 2025 employment situation report. At first glance, it contained the bad news that 2025 closed out with anemic job growth. But here, this bad news increased the likelihood the Fed will cut the Federal Funds Rate in 2026 after a pause, which benefits the companies that will be borrowing big to support their investments in AI technologies. The CME Group's FedWatch Tool projects the Fed will hold the Federal Funds Rate steady until 17 June (2026-Q2), when it anticipates a quarter point rate cut. The tool forecasts another quarter point reduction on 16 September (2026-Q3).

Investor attention however appears to remain focused on the current quarter of 2026-Q1, given the potential the Fed will announce its next rate sometime during the quarter. The latest update finds the trajectory of the S&P 500 falling within the middle of the chart's redzone forecast range, which assumes investors would be focused on 2026-Q1 while it runs.

There was a lot of new information investors had to absorb during the trading week ending on Friday, 9 January 2026. Here are the week's market-moving headlines:

At its core, the expression "outside-the-box thinking" refers to ideas that break out of the bounds of convention. This series features innovations that, somehow or another, do just that. In the case of today's featured example of inventiveness, quite literally.

Imagine you are carrying a briefcase as you walk in a public setting. The briefcase contains very important documents and valuable objects. Now imagine you've just realized that you're being followed by a shady character, who will soon make their move to take that briefcase and all its contents away from you. How will you keep from becoming just another robbery statistic? Better still, how will you avoid becoming the victim of an assault in the process?

Although it was never patented, inventor John H.T. Rinfret came up with a unique invention to address the problem of being robbed by thieves seeking to acquire briefcases and their valuable contents. Here's the story of his innovative "anti-bandit bag" from Atlas Obscura:

In 1963, The Manager and other publications described a spinoff—the Pug anti-bandit bag—that, rather than smoke, ejected the contents of a bag once a thief grabbed it.

Invented by John H. T. Rinfret, who was purportedly a frequent target of robberies, the Pug anti-bandit bag featured a spring attached to the handle. If a thief tried to steal the bag, the courier needed only to crook their thumb, and the bag flew open, its contents spewing everywhere. Presumably, this would frighten away the robber, and the day would be saved.

Necessity, as they say, is the mother of invention and by this account, Rinfret truly had the need. The following video shows how his innovation, the Pug Anti-Bandit Bag, worked in action after its proverbial panic button was pressed:

Alas, Rinfret's innovation never reached the marketplace. Weird Universe theorizes why not:

From what I can gather, Rinfret hoped to rent his anti-bandit bags to companies that used couriers to carry important documents or money. He definitely put a lot of work into promoting his invention. He even came out with a new and improved version of the bag the following year. But evidently few companies were interested in using his bag.

Possible reasons why: 1) a bandit might pick up the money instead of running away; or 2) what if the spring was activated by accident, spraying money everywhere?

If you've ever had to pick up the contents of a briefcase or suitcase that wasn't securely closed and came open, dumping its contents on the ground, you well understand why Rinfret's anti-bandit briefcase never caught on. Even if it worked exactly as intended, you would be guaranteed to still have a mess to clean up. A mess that you could expect to have to deal with far more often than you might ever have your briefcase attempted to be stolen from you.

In that sense, it was too outside-the-box to be successful.
