The 2026 Federal Budget: What it means for your portfolio

The 2026 Federal Budget: What it Means for your Portfolio

The Treasurer has handed down the most consequential Budget in a generation — one that tries to do three difficult things at once: cushion an oil shock, repair the bottom line, and reform the tax system.

Here’s what investors need to know;

On Tuesday 12 May, Treasurer Jim Chalmers delivered the 2026–27 Federal Budget the first Budget of Labor’s second term, and the first to be framed entirely around the global oil shock now reshaping Australia’s economic outlook. 
 
It is, on its own terms, a fiscally cautious document. The savings package is the largest on record. Real spending growth across the next eight years is forecast to average just 1.5 per cent — the lowest in almost three and a half decades. Every dollar of upgraded revenue has been returned to the bottom line. 
 
But it’s also one of the most ambitious reform Budgets in 25 years — with material changes to capital gains tax, negative gearing, business tax, energy markets, and the National Competition Policy. 
 
So what does that mean for investors’ portfolios? And how does it fit into the broader macro story, stagflation, the Iran conflict, the slowing Chinese economy, and the RBA’s increasingly narrow set of options? 
 
That’s what this piece is about. 

What’s actually in the 2026–27 Budget?

The headline numbers tell a more reassuring fiscal story than many were expecting. The underlying cash deficit for 2025–26 has been revised down to $28.3 billion — an $8.5 billion improvement on the Mid-Year Economic and Fiscal Outlook released in December. The 2026–27 deficit is forecast at $31.5 billion, $2.8 billion better than previously projected. Over the five years to 2029–30, the budget position has improved by a cumulative $44.9 billion.

Gross debt sits at $982 billion at the end of this financial year. According to the Treasurer, it peaks lower, peaks earlier, and is lower in every year for the next 11 years than previously forecast.

That’s the fiscal repair side. The reform side is where things get more interesting.

The major measures include:

• A $14.8 billion “Strengthening Australia’s Fuel Resilience” package,  including a $10 billion investment in immediate fuel supplies and a permanent Australian Fuel Security Reserve, a $1.1 billion Cleaner Fuels Program, and a 20 per cent domestic gas reservation for Australian users.
• Cost-of-living relief including more than halving the fuel excise, reducing the heavy vehicle road user charge to zero, and a new $250 Working Australians Tax Offset for 13.3 million workers from the second half of 2027 (a $6.4 billion measure).
• A $25 billion top-up for public hospitals, $5.9 billion for new listings on the Pharmaceutical Benefits Scheme, and $1.8 billion to permanently fund the 137 Medicare Urgent Care Clinics.
• A record $47 billion housing investment: including 5 per cent deposits for first home buyers, $2 billion for enabling infrastructure (roads, drains, power), and an extended ban on foreign purchases of existing dwellings.
• Capital gains tax reform: the existing 50 per cent CGT discount will be [replaced with cost base indexation from 1 July 2027, with a minimum 30 per cent tax rate on net capital gains.
• Negative gearing changes: losses from established residential properties acquired from 7:30 pm AEST on Budget night will only be deductible against rental income or capital gains from residential property. New builds retain the existing treatment.
• A minimum 30 per cent tax on distributions from discretionary trusts from July 2028.
• A $53 billion increase to defence spending over the decade, plus $800 million for veterans.
• An additional $3 billion for aged care, $2 billion for the Thriving Kids program, and $37.8 billion in NDIS savings over the forward estimates.
• A productivity package the Treasurer described as the broadest since the 1990s — cutting regulatory costs by $10.2 billion a year, removing nearly 600 tariffs, and reforming the National Electricity Market.

That’s a lot. So let’s break it down into what it actually means for the Australian economy and, by extension, the assets in investors’ portfolios.

The Macro Tension: Stimulus Arriving into an Inflation Problem

Here’s the dilemma at the heart of this Budget.

Treasury is now forecasting inflation to peak at around 5 per cent in the middle of this year, largely because of the war in Iran and the Strait of Hormuz disruption. Growth is forecast to slow to just 1¾ per cent in 2026–27 — half a percentage point lower than expected before the conflict.

In other words, the economy is heading into exactly the kind of “running hot and cold at the same time” environment we described last week— where central banks have fewer easy options than they’ve had in decades.

Into that environment, the government is injecting an estimated $18.3 billion in additional spending in 2026-27. The fuel excise cut, the tax offset, the hospital funding and the housing infrastructure spend all flow into the real economy. So even though the deficit is shrinking on paper, the fiscal stance — the change in spending and revenue from one year to the next — is mildly expansionary.

That’s the part that may complicate the RBA’s job.

On one hand, halving the fuel excise will mechanically reduce headline inflation. On the other hand, putting $54 a week back in the average earner’s pocket adds to demand at a time when supply constraints are precisely what’s driving prices higher. The Treasury itself acknowledges a more severe scenario in which oil peaks at US$200 a barrel — a path on which inflation would peak above 7 per cent and unemployment would spike to pre-pandemic levels.

So what looks fiscally responsible in the abstract may, in practice, mean interest rates stay higher for longer than the market is currently pricing.

And that has direct implications for both bonds and shares.

A historical comparison: this is not 1975, and it’s not 2014 

There’s a temptation, when a Budget lands in the middle of an inflation problem, to reach for the most dramatic historical analogy. But it’s worth being careful about which analogy you reach for. 
 
This isn’t the 1974–75 Whitlam Budget, which was handed down with inflation already at 16 per cent, a highly centralised wage system, and government spending growing at double-digit rates. Wage growth today is contained at around 3 per cent. Real spending growth across the forwards averages 1.5 per cent. The fiscal architecture is fundamentally more disciplined. 
 
Nor is this the 2014 Hockey Budget, which tried to repair the bottom line through politically explosive spending cuts. Chalmers has done his repair largely through NDIS reform and revenue gains, not through frontal assaults on Medicare or social security. 
 
The closer parallel is probably the Costello Budgets of the early 2000s — fiscally cautious headline numbers paired with substantial structural tax reform (the GST then; CGT and negative gearing now). What’s different is that Costello had a mining boom to ride. Chalmers has an oil shock and a slowing China. 
 
The lesson here is that Budgets don’t move markets on the night they’re delivered. They shape the medium-term path of growth, inflation, taxes and bond supply — and it’s those second-order effects, playing out over the next 12 to 24 months, that investors should be positioning for. 

Three things’ investors should be watching 

1. The bond supply story is changing — but more slowly than feared

The 2025–26 issuance program was already large — around $125 billion in Treasury Bonds — and gross debt is now sitting just shy of a trillion dollars. With deficits continuing through the forwards and a $53 billion defence top-up, AOFM will need to keep issuing at scale.

That matters because, all else equal, more bond supply pushes yields up. 

But there are offsetting forces. Real spending growth is restrained. The deficit profile is improving. And the structural shifts in the global investor base for sovereign debt mean Australia’s strong relative position — one of the lowest debt-to-GDP ratios in the OECD — remains an asset.

The upshot is that Australian government bond yields may stay elevated for some time, which is unhelpful for borrowers but useful for income-focused investors who can lock in coupons at levels not seen since before the GFC.

2. The tax changes will reshape capital flows 

This is the part of the Budget that may have the most enduring market consequences.

Replacing the 50 per cent CGT discount with indexation, and limiting negative gearing to new builds, doesn’t just affect property investors. It changes the relative attractiveness of leveraged residential property versus other asset classes — including shares, fixed income, and productive business investment.

Existing investments are grandfathered, so the immediate effect is muted. But on the margin, capital that would have flowed into a second or third investment property after 12 May may now flow elsewhere. Some of that will go into new construction (which retains the existing concessions). Some may go into the share market, into super, or into other income-generating assets.

Combined with the $3.5 billion in business tax measures — including a permanent two-year loss carry-back for companies up to $1 billion in turnover, expanded venture capital incentives, and a better-targeted R&D Tax Incentive — the overall direction of travel is toward rebalancing investment incentives away from passive asset accumulation and toward productive capital.

The 30 per cent minimum tax on discretionary trust distributions from July 2028 is also worth watching closely, given how widely trusts are used by Australian families and SMEs.

3. The AUD remains the swing variable 

The Australian dollar tends to behave as a high-beta proxy for global growth and commodity prices. None of those forces are working in its favour right now.

China’s growth is slowing. Iron ore prices remain volatile. Oil — which Australia imports heavily — is elevated. And the interest rate differential with the US is unlikely to widen meaningfully in our favour, given Treasury’s growth downgrade.

A weaker AUD imports more inflation, particularly in fuel and tradeable goods, and complicates the RBA’s task further. It can be a tailwind for unhedged international equity holdings, and for ASX-listed exporters with US-dollar revenue streams. But it’s also a reminder that currency risk in 2026 deserves more attention than it did in 2021.

Three things to consider 

So what can investors actually do? The temptation after a Budget is to do something dramatic. That’s almost always the wrong instinct. But there are some practical, considered moves worth thinking about.

1. Don’t underweight defensive income 

If the macro backdrop is genuinely one of sticky inflation, slowing growth and elevated geopolitical risk — and the Budget itself does very little to change that — then the case for a meaningful defensive allocation is stronger now, not weaker.

When equity markets price the same future earnings at lower multiples (because higher discount rates compress valuations), the portfolio role traditionally played by bonds becomes more valuable, not less. Quality actively managed fixed income is one of the few asset classes currently offering meaningful real income.

Yields on Australian credit are at levels that haven’t been available for the better part of two decades. That doesn’t make fixed income a substitute for growth assets, but it does mean the defensive sleeve of investors’ portfolios can finally do some serious heavy lifting again.

The Skyring Fixed Income Fund is one way to access actively managed Australian credit, with a focus on income reliability through volatile cycles. 

2. Reassess the tax structure of investments 

The tax changes don’t take effect until 1 July 2027 (for negative gearing on properties acquired after Budget night) and 1 July 2027 (for the CGT changes). That gives investors time to think clearly rather than react emotionally.

For property investors, the key questions are: which assets are grandfathered, what’s the appropriate balance of new versus established stock, and how does the change in CGT treatment affect the hold-versus-sell decision on existing holdings?

For investors with significant unrealised gains in shares or other CGT assets, the question is whether realisation prior to 1 July 2027 makes sense — but the answer will depend on individual circumstances, including marginal tax rates, the inflation-adjusted cost base, and the timing of intended sales anyway.

This is precisely the kind of decision where professional tax and financial advice tends to pay for itself many times over. Skyring doesn’t provide that advice — but we’d encourage anyone with material exposure to these areas to seek it before making changes.

3. Stay focused on portfolio structure, not the headlines 

The single most important thing to remember about a Budget — any Budget — is that it doesn’t change the fundamental discipline of good portfolio construction.

A well-built portfolio is diversified across asset classes that don’t all move in the same direction at the same time. It’s rebalanced periodically so target allocations don’t drift. It generates income through the cycle, rather than relying solely on capital appreciation. And it’s built to withstand uncertainty, not to predict it.

The 2026 Budget doesn’t change any of that. What it does is reinforce why those principles matter — because the macro environment it’s responding to (elevated inflation, slowing growth, geopolitical risk, structural change in tax and energy) is precisely the kind of environment in which discipline pays and dramatic moves don’t.

The bottom line: a careful Budget for an uncertain time  

Taken together, the 2026–27 Budget is fiscally cautious, structurally ambitious, and politically considered. It does meaningful repair on the bottom line. It introduces the most significant tax reforms in a quarter of a century. And it acknowledges, without flinching, that Australia is dealing with its fifth major economic shock in less than 20 years.

But it doesn’t change the underlying macro picture. Inflation is still elevated. Growth is still slowing. The RBA still has a difficult job. And the global backdrop — oil, China, geopolitical fragmentation — remains genuinely uncertain. This puts a lot of pressure on the everyday investor, new and seasoned.

That means the same things it meant before Tuesday; Stay diversified. Don’t overpay for growth. Let defensive allocation do its job. And remember that what matters is not what happens on Budget night, but how the economy and markets evolve over the next 12 to 24 months.

A portfolio built for uncertainty doesn’t need a perfect Budget. It just needs to still be standing — and still be balanced — when the dust settles.
