ABS Lending Indicators March Quarter 2026: Investor Loans Down 5.3% — The First Post-Hike Mortgage Snapshot

The Australian Bureau of Statistics released its Lending Indicators bulletin for the March quarter 2026 on 13 May 2026. It is the first Tier-1 mortgage dataset that captures the full impact of the early-2026 policy regime change — two RBA cash rate hikes (to 3.85% on 3 February and 4.10% on 17 March), APRA's debt-to-income cap activated on 1 February, and the first quarter in which the cumulative effect of three years of supply-side tightening, regulator action, and macroeconomic crosswinds shows up in mortgage origination volumes.

The headline is clear: new lending fell across every segment. Total new dwelling loan commitments dropped 6.2% by number and 3.8% by value over the quarter. Owner-occupier volumes fell 6.9%, investor volumes 5.3%, first home buyer volumes 4.3%. On the surface, this is the slowdown the macroprudential settings were designed to produce.

But the headline obscures the texture. New investor commitments are still 18.8% higher than a year ago by volume, and 25.3% higher by value. Internal refinancing by investors is up 30.3% year-on-year — the largest YoY move in any series in the bulletin. Construction lending is up 58.1% year-on-year. The quarter-on-quarter print looks like a slowdown; the year-on-year print looks like a market still running hot, just less hot than the December quarter.

This piece reads the 13 May release three ways — q/q, y/y, and against the policy backdrop — then walks through the investor and owner-occupier breakdowns, examines state-level loan sizes, decodes the refinancing surge, reconciles the lending data against the Cotality, PropTrack and SQM releases we have already covered, and sets out the cohort-by-cohort read-through. We covered the macroprudential lever activation in our APRA DTI Rules 2026 blog; the rate decisions that bracket this quarter are covered in our February 3.85% hike analysis and March 4.10% hike analysis. The 13 May ABS data is where those policy moves first show up in the borrower behaviour.

1. The Headline Numbers, Read Three Ways

A single quarter's lending data can be read several ways, and the right reading depends on what question the investor is trying to answer. We read this one against three reference points: the prior quarter, the prior year, and the cumulative policy stack that defined Q1 2026.

Quarter-on-quarter: a clean step down across every segment

The seasonally adjusted Q1 2026 print produced negative q/q changes in every dwelling-finance segment. Volumes fell harder than values, which means the loans that did settle in Q1 were larger on average — visible in the average loan size data later in this piece.

The q/q fall reverses three consecutive quarters of growth that ran through most of 2025. It is the cleanest directional reversal in the lending data since the early 2023 cycle, and it arrived in the precise window — February to March 2026 — when monetary and macroprudential settings tightened simultaneously.

Year-on-year: still well above March 2025

The same dataset reads very differently on a y/y basis. Total dwelling loans are +8.6% by number and +18.5% by value compared to March 2025. The investor segment alone is +18.8% by number and +25.3% by value. First home buyer values are +17.9% y/y. Construction lending is +58.1% y/y.

This is not a market in retreat. It is a market that grew strongly through 2025, peaked in the December quarter, and has now taken its first step back. The level of activity in Q1 2026 is still materially higher than the same quarter a year ago — particularly on the investor side, where YoY value growth (+25.3%) is now running nearly three times the rate of owner-occupier value growth (+14.3%).

Against the policy stack: every lever pushed the same way

Three policy levers tightened during the period the dataset captures:

1. RBA cash rate +25bps to 3.85% on 3 February 2026 — ended Australia's brief 2025 cutting cycle and reset the borrower-serviceability assumption. The serviceability buffer (3 percentage points above the actual rate) lifted lender assessment rates from ~9.0% to ~9.25%.
2. APRA DTI cap activation on 1 February 2026 — banks restricted to 20% of new lending at DTI ≥6×, measured separately for owner-occupier and investor portfolios. New dwelling lending exempt.
3. RBA cash rate +25bps to 4.10% on 17 March 2026 — second hike in six weeks, with serviceability buffers re-stepping again by quarter end.

All three pulled in the same direction. The −6.2% headline fall is the borrower behaviour response to that combined push. What the data does not yet capture — and which we will track in the next release — is the impact of the 6 May 2026 hike to 4.35% (which sits in Q2) and the 12 May 2026 Federal Budget changes to negative gearing and CGT (also in Q2). Q1 is the first post-hike snapshot; Q2 will be the full post-hike-and-post-Budget snapshot.

2. Investor Loans — The Number That Matters Most for This Audience

The investor segment is the one we read most closely on this site, and it has three features worth unpacking.

Volume down 5.3%, value down only 3.0% — the bifurcation signal

New investor loan commitments fell 5.3% by number to 57,342 in the quarter, but only 3.0% by value to $41.5 billion. The implication: the average investor loan grew. The seasonally adjusted national investor average loan size now sits at $709,000, up from $696,000 in December 2025 — a 1.9% q/q increase in loan size even as volumes fell.

This is the bifurcation signal. The investors who exited the market in Q1 — or who were declined under tighter serviceability and DTI tests — were skewed toward the lower end of the loan-size distribution. The investors who remained were larger borrowers, or were borrowing in higher-priced markets where average ticket sizes are structurally larger. For comparison, the same series two years earlier averaged ~$640,000 nationally. Even with volume softer, average ticket size is materially higher.

Investor share of new lending edged higher

Despite falling in volume, investors took a larger share of new lending in Q1 than in Q4. By value, investors accounted for ~40.3% in Q1 2026, up from ~39.6% in Q4 2025. This is the third consecutive quarter of investor share expansion.

The DTI cap was designed in part to slow this share growth. The Q1 data suggests it tempered the absolute volume but not the relative share — owner-occupier lending fell harder (−6.9% volume) than investor lending did (−5.3%). One reading: investors with stronger income profiles, larger equity bases, and access to portfolio refinancing options were less constrained by the cap than marginal owner-occupier borrowers.

Year-on-year +18.8% — the long-run trajectory has not broken

Despite the q/q fall, investor commitments are still 18.8% higher than the same quarter a year ago. That is not a statistical artifact — it reflects the genuine acceleration of investor activity that ran through 2025 as interest rates fell, rental yields rose, and capital growth in supply-constrained markets compounded. The structural drivers have not gone away. Vacancy rates remain ultra-tight (1.2% nationally per our SQM April vacancy analysis). Asking rents are still up 7.3% YoY. The supply pipeline remains constrained. What changed in Q1 2026 was the cost of accessing investor finance, not the underlying yield arithmetic.

3. Owner-Occupier and First Home Buyer Breakdown

If investors held up better than the headline suggests, owner-occupiers and first home buyers absorbed the harder share of the slowdown. OO volumes fell 6.9% q/q to 82,453 commitments. The OO value fell 4.3% to $61.4 billion. That gap — bigger volume drop than value drop — again suggests it is the lower end of the OO distribution that fell out, not the top.

First home buyers fell 4.3% by volume and 6.7% by value — the only segment where the value drop exceeded the volume drop. The implication: FHBs who did transact in Q1 borrowed less than FHBs who transacted in Q4. The mix is shifting to smaller properties and tighter loan sizes, consistent with a serviceability-constrained cohort facing a 9.25% assessment rate.

The non-first home buyer owner-occupier cohort — upgraders, downsizers, relocations — fell 6.4% by volume and 5.0% by value. This cohort is typically the most rate-sensitive because their move is discretionary in a way an FHB's first purchase is not. When rates move 50bps in six weeks, the upgrader who was going to extend their loan by $300,000 reconsiders. Many appear to have deferred.

4. State-by-State: Where the Loan Sizes Sit

The ABS bulletin reports average loan sizes by state for both owner-occupier and investor cohorts. The geographic spread is wider than the national averages suggest.

Owner-occupier average loan sizes, March 2026

NSW is now $125,000 above the national average and $339,000 above Tasmania. Queensland has overtaken Victoria — Brisbane house values have run hard through 2025–26, and the average OO loan size now reflects that. WA has also overtaken Victoria; this is the first quarter on record where the WA OO loan size exceeds the Victorian equivalent.

Investor average loan sizes, March 2026

NSW investor average is $857,000 — only $3,000 less than the NSW OO average. In every other state, investor averages run materially below owner-occupier averages, sometimes by $50,000–$70,000. The NSW gap closure is a Sydney-specific story: investors transacting in Sydney are paying a price that approximates what owner-occupiers pay, because Sydney's investment stock and owner-occupier stock now sit in the same price bands at the entry level.

The DTI cap, the rate hikes, and the serviceability buffer all bite differently at $857,000 versus $427,000. A NSW investor at $857,000 is far more exposed to the 6× DTI ceiling than an NT investor at $427,000. If the Q2 print shows NSW investor loan sizes falling and NT/SA/QLD investor loan sizes rising, that is the macroprudential cap doing its work. If NSW continues to grow even as other states soften, the cap is being navigated rather than enforced — likely through new-dwelling exemptions and non-bank lender flow.

5. The Refinancing Surge — A Quiet Counter-Signal

The lending data table that nobody quotes in the news headlines is refinancing. It is where the Q1 2026 release tells its most interesting story.

Investor internal refinancing +30.3% YoY

Internal refinancing — where a borrower switches loan product with their existing lender rather than moving to a new lender — surged for investors. Volume up 3.3% q/q and 30.3% year-on-year. Value up 3.6% q/q and 41.2% year-on-year. This is the largest YoY move in any single series in the bulletin.

It is also the cleanest evidence that lenders are competing aggressively for retention of existing investor borrowers. As serviceability buffers tightened, lenders that would otherwise lose marginal investor business to a competitor responded with internal refinancing offers — fixed-to-variable conversions, interest-only term extensions, offset structure changes, and discounted variable rates.

Investor external refinancing softened

External refinancing — where a borrower moves to a new lender — fell 0.2% q/q in volume terms and 0.8% in value terms, although it is still up 10.9% and 17.7% YoY. The slight q/q softening of external refi alongside a strong internal-refi quarter is the signal: borrowers are being held in place by their existing lender rather than shopping the market. For investors evaluating whether to refinance in Q2 or Q3, the implication is direct. The market is competitive again. Existing lenders will negotiate. Brokers reporting that 2026 is a "harder refi market" because of the rate cycle are reading the headline; they are not reading the internal-refi sub-series.

6. Construction Lending +58.1% YoY — Pre-Budget Distortion or Structural Shift?

Business finance for construction came in at $12.2 billion in Q1 2026 — up 4.8% q/q and 58.1% year-on-year. This is the biggest YoY move in any single series across the entire bulletin.

Construction lending sits in the business finance table, not the dwelling commitments table, so it captures lending to developers and builders rather than to households buying off the plan. A +58.1% YoY move in this series is consistent with a meaningful step-up in new project starts — exactly what HIA modelling and ABS Building Approvals data have flagged through late 2025 and early 2026.

It is also consistent with the supply response that the 2024–25 negative gearing reform debate, the Housing Australia Future Fund deployment, and state-level build-to-rent policies were designed to encourage. By March 2026, the pipeline was clearly responding. The 12 May 2026 Federal Budget then exempted new builds from the negative gearing carve-out — established stock purchased post-7:30pm on 12 May 2026 has rental losses quarantined; new builds remain fully geared. That policy lever applies after the quarter this dataset captures. But the Q1 construction lending move suggests builders, developers, and their financiers were positioning ahead of that policy change.

Business finance for property purchase (commercial property acquisitions by businesses, not residential) fell 4.0% q/q to $26.0 billion, although it is still up 21.9% YoY. Commercial property buyers paused harder than residential developers in Q1 — a pattern that typically front-runs broader business investment cycles by one to two quarters.

7. Cross-Source Reconciliation

The ABS lending data does not exist in isolation. It needs to be read against the price, rent, vacancy and bank-specific datasets that have already landed for the same window.

Versus Cotality and PropTrack. Cotality's Housing Chart Pack May 2026 showed combined-capitals national index up just 1.6% over three months — the softest 3-month print since April 2025 — with Sydney and Melbourne in monthly decline by April. PropTrack's Home Price Index April 2026 recorded the first national monthly fall of 2026 at −0.1%. The price softness in those datasets is consistent with the volume softness in the ABS data. Fewer transactions, slightly smaller average tickets, and price growth flattening or reversing in the largest two capitals — these all move together.

Versus NAB Housing Monitor. NAB's April Housing Monitor called ~5% growth for the 8-capital index in 2026, with Perth +30% vs Melbourne −2.5% on 3-month annualised. The ABS lending data does not show a national contraction — it shows a moderation. Both can be true: the 8-capital index can grow ~5% on the year while quarterly lending volumes step back from the December peak. NAB is forecasting the annual outcome; ABS is reporting the quarterly trajectory. The Q1 step-back is fully consistent with a ~5% annual outcome if Q2–Q4 reaccelerate modestly from this base.

Versus SQM rental data. SQM's April vacancy at 1.2% was the first material monthly rise in 12 months. The ABS lending fall and SQM vacancy rise are not contradictory — they are different sides of the same story. Fewer purchases mean more rental demand at the margin; tighter serviceability means more tenants stay tenants for longer; and the cumulative supply response that started in 2025 is now beginning to add stock to the rental pool, lifting vacancy from 1.0% to 1.2% even as transaction activity slows.

8. What the Data Does Not Yet Show

Three material events sit outside the window the 13 May ABS release captures, and each will reshape the Q2 print due in mid-August 2026.

The 6 May rate hike to 4.35%. The third RBA hike of 2026 landed in the first week of Q2. The ABS data captures lending to 31 March 2026. The full impact of the cumulative 75bps of hikes on borrower serviceability — assessment rates now approaching 9.6% — will not appear until the Q2 release. Expect a continuation of the q/q step-down, possibly steeper, particularly in the FHB and marginal-OO cohorts.

The 12 May Budget changes. Negative gearing quarantined on established stock acquired after 7:30pm on 12 May 2026. CGT 50% discount replaced with cost-base indexation and a 30% minimum rate, applying to assets sold after 1 July 2027 (with grandfathering for assets acquired before the 12 May trigger). Build-to-rent and new-dwelling carve-outs preserved. Widely-held trusts and superannuation funds exempt. The Q2 ABS data will show whether the carve-outs create a measurable shift in investor lending toward new dwellings and toward SMSF structures.

The 1 July 2026 Division 296 commencement. The $3M super tax commences 1 July 2026, with first measurement at 30 June 2027. SMSF property-acquisition activity in Q2 — particularly via LRBA structures — will be visible in the next ABS print. Our Division 296 action guide covers the strategy framework.

9. Cohort-by-Cohort Read-Through

The Q1 2026 lending data does not produce a single uniform implication. Each investor cohort should read it differently.

The yield-led investor (sub-$700K, regional or outer-metro)

For the investor targeting sub-$700K stock in tighter-yield markets (regional QLD, SA, outer-metro Perth/Adelaide), the lending data is broadly neutral. Average loan sizes in SA ($639K), WA ($654K), and QLD ($711K) sit close to the national investor average. The DTI cap is less of a binding constraint at these ticket sizes for a moderate-income borrower. The 5.3% q/q fall in investor volume is more likely a Sydney/Melbourne-led phenomenon than a regional one. Read-through: continue to pursue, but expect tighter assessment rates and broker-led lender selection to matter more in Q2 than they did in Q4 2025.

The capital-growth investor (Sydney/Melbourne, $850K+)

For the NSW investor running at the $857K average, the picture is harder. DTI cap exposure is real. Serviceability buffer compression is real. Cotality and PropTrack are both flagging Sydney monthly declines. Asset prices may continue to soften through Q2. Read-through: this is the cohort the macroprudential settings are most explicitly targeting. The Q1 data shows the pinch; the Q2 data will likely show it more clearly. For long-horizon investors, this may represent the cleanest entry window since 2023 — but timing within that window depends on rental holding cost vs capital growth expectation.

The SMSF investor

The SMSF cohort is largely shielded from the headline lending data. SMSF property acquisitions through LRBA structures are a small share of total investor lending, and the cohort is exempt from the post-Budget NG/CGT regime. With Division 296 commencing 1 July 2026, the binding question for this cohort is balance management and cost-base election timing — not lending availability. Read-through: the lending data is not the main signal. The Division 296 mechanics are.

The new-build investor

For the investor specifically targeting new dwellings, the data is positive on three fronts. First, new dwellings are exempt from the APRA DTI cap, so lender capacity is unconstrained at high DTI ratios. Second, new builds are exempt from the post-Budget NG carve-out. Third, construction lending up 58.1% YoY signals a supply pipeline that is responding — more product, more competition among developers, and likely better terms for buyers in late 2026 and into 2027. Read-through: the policy stack now actively rewards new-build investment over established-stock investment. The Q1 lending data is the first datapoint that begins to quantify the shift.

10. What to Watch in the Q2 Release

The Q2 2026 Lending Indicators release will land around 13 August 2026. Three things will matter most.

1. Investor share of new lending. Did the Budget shift investor capital toward new builds at a measurable rate? Watch the gap between OO and investor volume changes — if investor volumes hold up better than OO, the carve-outs are working as positioning.
2. NSW vs Queensland/WA investor loan size. If NSW investor average loan size falls and QLD/WA/SA rise, the DTI cap is redistributing capital to lower-priced markets. If NSW continues to expand, the cap is being navigated.
3. Construction lending continuation. A second consecutive +50%+ YoY print in construction lending would signal a genuine supply-side response. A reversion to ~+20% YoY would suggest the Q1 print was a one-off positioning move ahead of the Budget.

We will publish the Q2 2026 analysis in mid-August 2026 alongside the August Cotality Chart Pack, NAB Housing Monitor, and the first Cotality HVI release reflecting the post-Budget month of June.
