US Housing Inventory Edges Up Year-Over-Year Amidst Rising Mortgage Rates

US housing inventory has experienced a modest year-over-year increase, reaching 871,063 single-family homes by the week of August 14, 2026. This figure represents a slight uptick from the 865,709 homes recorded the previous week (August 7–August 14, 2026), and compares favorably to the 860,055 homes observed during the same week of the prior year (August 8-15, 2025). The current inventory levels are gradually approaching the historical average for seasonal peak periods, which typically hovers around 1 million single-family homes. This contrasts sharply with the record-low inventory levels that characterized the housing market during the COVID-19 pandemic, a period marked by unprecedented demand and supply chain disruptions. The current, albeit light, growth in inventory is primarily attributed to the interplay of higher mortgage rates and a subsequent softening in housing demand. This phenomenon, where elevated borrowing costs tend to cool buyer activity, has been a consistent trend observed in housing data for years. Specifically, demand typically begins to soften when mortgage rates exceed the 6.64% mark. In 2026, while mortgage rates have been closer to yearly highs, they have largely remained below the 7% threshold, preventing a more significant surge in inventory. The easier year-over-year comparisons also contribute to the observed growth; in the previous year, mortgage rates were declining towards 6%, which spurred increased demand and consequently limited inventory growth. As the current year progresses, these year-over-year comparisons will become even more favorable for showcasing inventory increases. New listings, a crucial component of overall housing supply, are currently following their traditional seasonal trajectory, exhibiting a decline as the market transitions towards the fall and winter months. During peak periods, weekly new listings typically range between 80,000 and 100,000 homes. While these figures have not yet fully rebounded to the levels seen between 2013 and 2019, they have now reached the lower end of what is considered a normal range for new listings. The article also provides historical context, differentiating current new listing trends from those observed during the housing bubble years, when new listings saw a more pronounced increase. The ongoing geopolitical situation, specifically the "Iran conflict" now in its sixth month, and the persistent upward pressure on mortgage rates are additional macroeconomic factors influencing the dynamics of the housing market. The analysis suggests that despite the subdued nature of inventory growth, the market is incrementally moving towards more normalized levels, with the possibility of further slight increases before the onset of the typical seasonal decline in housing activity.
