Hong Kong home sales fell 21.0% from a year earlier in October to 4,512 residential sale and purchase agreements, the Land Registry said on Tuesday, as the market lost more of the momentum it built in the first half of the year. The value of those deals dropped 17.1% to HK$42.3 billion.

For investors in the city's developers and banks, the figures point to a market that is still active but no longer accelerating. Volumes fell 5.2% from September, and the value of residential agreements slid 9.5% on the month, a larger drop than the count. That suggests buyers are moving into cheaper flats. The average October agreement worked out at roughly HK$9.4 million, down from about HK$9.8 million in September, based on the registry's totals.

Land Registry data show a second weak month

Residential deals have now run below year-earlier levels for three straight months. In September, the registry counted 4,761 residential agreements, 15.6% fewer than a year before, according to The Standard. That figure was itself a rebound of 18.5% from a quiet August.

Across all building units, including shops, offices and car parks, the registry received 5,795 agreements in October, down 10.0% from September and 19.4% from a year earlier. Their combined value was HK$50.0 billion, 13.6% below October 2025.

The longer-run picture is firmer. The 12-month moving average of all agreements stood at 7,566 in October, 16.7% above its level a year earlier, though 1.5% below September's reading. Residential deals for the first 10 months of 2026 totalled about 58,560, roughly 14% more than in the same period of 2025, based on registry figures compiled by the Rating and Valuation Department.

Much of that lead was built in the spring. Residential agreements peaked at 7,650 in June, worth HK$75.6 billion, before dropping to 4,462 in July and 4,019 in August, the department's figures show. The second quarter alone produced 22,156 residential deals, against 13,242 in the third quarter. October's total was the third-lowest monthly count of 2026, ahead of only July and August.

Timing matters when reading the data. Deeds can reach the registry up to 30 days after a sale, so October's count largely reflects deals struck in September.

Developer sales slump after a busy first half

The slowdown has been sharpest in the primary market, where developers such as Sun Hung Kai Properties, Henderson Land and New World Development sell new flats. The Rating and Valuation Department's November supplement, released this week, shows primary agreements fell to 3,240 in the third quarter from 6,997 in the second quarter. That was about 42% below the 5,620 recorded in the third quarter of 2025.

July was especially thin, with just 796 primary agreements, the lowest monthly total in the department's table going back to early 2025. New-home deals recovered to 1,502 in September as developers brought fresh projects to market, but their share of all residential sales, at 24% in the third quarter, was well below the 32% of the second quarter.

The secondary market has held up better. Resale agreements numbered 10,002 in the third quarter, down from 15,159 in the second quarter but still close to the 11,080 of a year earlier. The department's breakdown does not yet cover October.

Prices have so far absorbed the cooling in volumes. The department's index showed private home prices up 9.3% from a year earlier in September, as Capital Times reported last week, while rents reached a record. Supply is the main risk for developers, with the pipeline of new private flats now about 100,000 units.

What to watch

For developers, the question is whether sharper pricing on new launches will be needed to clear that stock. Banks will watch mortgage demand: lower average deal sizes mean smaller loans, even if the number of buyers holds steady.

The next data points arrive within weeks. The Rating and Valuation Department is due to publish its October price index later this month, and the Land Registry releases its November transaction figures in early December.
