UBS: Mortgage Subsidy Expectations Drive Property Stocks Up 10%, but Sustainability in Question
nashnova research
Chinese property stocks have rallied 10% since September 18 on bets that a mortgage interest subsidy will land before the National Day holiday; UBS says the actual impact may fall short, with subsidy scope and duration as the two key unknowns.
What is the market betting on?
The expected policy: an interest subsidy of 40 to 100 basis points on new mortgages for first-home new-build purchases.
This means → on a one-million-yuan mortgage, annual interest could drop by roughly ¥10,000 at most.
UBS flags two uncertainties: existing mortgages and second-hand home loans may be excluded, and how long the subsidy lasts remains unclear.
Is the subsidy enough to turn renters into buyers?
The current first-home mortgage rate is 3.05%. A 40–100 bp subsidy would bring it to 2.05%–2.65%.
Rental yields in tier-1 cities sit at about 1.7%; tier-2 at 2.4%. In plain terms = "buying beats renting" only works once the mortgage rate drops to — or below — the rental yield.
UBS sees signs that rents are stabilizing: less new supply from completions and social housing, plus falling vacancy in tier-1 suburban areas. This reflects a possible floor forming on the rental side.
If second-hand homes and existing mortgages are left out, how much does the effect shrink?
Second-hand transactions made up roughly 50% of all home sales in 2025, and listings remain elevated — still the main drag on prices.
This means → subsidizing only new-build mortgages covers just half the market; the other half — where the most pressure sits — stays untouched.
The fiscal math makes the gap starker: subsidizing existing mortgages costs about 10 times as much as new-build-only support. Outstanding mortgage balances total roughly ¥38 trillion; at 100 bp, that is ¥380 billion a year — versus about ¥40 billion for new-build subsidies alone.
Could a housing-fund rate cut be the stronger card?
UBS argues that cutting the Housing Provident Fund loan rate — a state-managed low-interest mortgage facility — may work better than a subsidy, for two reasons: the effect is more durable, and it could cover both new and second-hand homes.
Since 2016, the Provident Fund rate has been cut only three times, by a cumulative 65 bp; over the same period the LPR — the benchmark for commercial mortgages — has been cut nine times, by a cumulative 140 bp.
In plain terms = the Provident Fund rate has far more room to fall than commercial rates do — and the policy lever is sitting right there.
Which stocks could benefit — and what to watch next?
UBS notes that if the subsidy lands, developers trading at low price-to-book stand to gain most, including Vanke, Longfor, Yuexiu Property, and Seazen.
Whether the sector's 10% rally can extend hinges on two verification points: subsidy scope (does it include second-hand homes and existing mortgages?) and subsidy duration.
This reflects where the market stands right now: expectations have run ahead of the policy — the details of delivery will determine whether this rally is a starting point or the finish line.
