The National Association of Realtors® (NAR) released the latest monthly data for its pending home sales index. The index rose 3.4% in March to 78.2, its highest level in over a year and more than the forecasted 0.3% growth. Pending home sales are up 0.1% from one year ago.
"March's Pending Home Sales Index – at 78.2 – marks the best performance in a year, but it still remains in a fairly narrow range over the last 12 months without a measurable breakout," said NAR Chief Economist Lawrence Yun. "Meaningful gains will only occur with declining mortgage rates and rising inventory."
"Home sales have lingered at 30-year lows, and since 70 million more Americans live in the country now compared to three decades ago, it's inevitable that sales will rise in coming years," explained Yun. "Inventory will grow steadily from more home construction, and various life-changing events will require people to trade up, trade down or move to another location."
Pending Home Sales Background
The pending home sales index (PHSI) was created by the National Association of Relators to track home sales where the contract is signed, but the transaction has not yet closed. An index of 100 is equal to the level of contract activity in 2001. The PHSI is a leading economic indicator of future existing home sales.
The chart below gives us a snapshot of the index since 2001, the first year data was analyzed. 
Over this time frame, the US population has grown by 18.5%. For a better look at the underlying trend, here is an overlay with the nominal index and the population-adjusted variant. The focus is pending home sales growth since 2001.
The above chart shows the percent off turn-of-the-century values. The index for the most recent month is currently 39% below its all-time high from August 2020. The population-adjusted index is 46% off its high from April 2005.
