Key takeaways
- The US interest rate outlook has become notably more benign. The Federal Reserve now expects solid growth, low unemployment and inflation returning to target, with only a little more tightening to come.
- At its September 2026 meeting the Fed lifted rates by 0.25%, its first hike since 2023, and its projections point to just one more increase before rates peak.
- The Fed sees inflation easing back toward its 2% goal over the next few years, even with unemployment staying low.
- Morgans' view is that stronger productivity, driven by heavy investment in data centres and AI, is the engine behind this rare mix of high growth, low inflation and a rate cycle near its peak.
- For investors, a clearer rate path with contained inflation is generally supportive, though the near term still carries uncertainty.
For investors, few things matter more than the direction of US interest rates. They influence everything from share valuations to the Australian dollar. So the latest US interest rate outlook from the Federal Reserve is worth a close look, because it paints a far more encouraging picture than the higher‑for‑longer scenario many investors had feared. In this article we explain what the Fed released, how it compares with its previous projections, what is driving the change, and what it could mean for your portfolio.
What the Fed actually released
Alongside its September 2026 interest rate decision, the Federal Reserve published its Summary of Economic Projections, or SEP. This is a quarterly snapshot of where the central bank's own officials expect growth, unemployment, inflation and interest rates to head over the next few years. It is the closest thing the market gets to official forward guidance, even from a chair like Kevin Warsh who is publicly sceptical of the practice.
At the meeting itself, the Fed lifted its benchmark rate by 0.25% (25 basis points) to a target range of 3.75% to 4.00%. It was the first rate rise since 2023. What made the projections striking was not the hike, but how comfortable the medium‑term outlook looked.
A stronger outlook, with rates near the peak
Compared with its June projections, the Fed now expects stronger growth and lower unemployment, while still seeing inflation return to target. It nudged its projected rate path a little higher to deal with near‑term inflation, but the peak is close and cuts are expected to follow. The table below sets the September medians against the prior June figures.
The pattern is unusual. Growth stays above its long‑run trend of 2%, unemployment holds around 4.1% right through to 2029, and yet inflation still drifts back to the 2% target. Normally, an economy running this hot would generate more inflation, not less.
Near the peak on rates
The rate path is the good news for borrowers and investors. After this month's increase, the Fed's projections suggest it will need only one more 0.25% hike, likely in December, taking the rate to a peak of around 4.1%. That would mean just two rate rises in the entire cycle.
From there, the Fed expects to start cutting. Its projections show rates easing through 2028 and 2029 toward a longer‑run level of about 3.2%. In short, the market is close to the top of the rate cycle, with gradual relief expected to follow.
The engine: productivity and the data centre boom
How does the Fed expect strong growth and low unemployment without an inflation problem? Morgans' view is that the answer is productivity.
Productivity is simply how much the economy can produce for a given amount of work. When it rises, businesses can grow and pay wages without pushing prices up. The Fed appears to believe the enormous wave of investment in data centres and artificial intelligence is lifting productivity, and that this is what allows faster growth and softer inflation to sit side by side. It is this productivity effect, on Morgans' reading, that underpins the rare combination of high growth, low inflation and a rate cycle that peaks early and eases over time.
It is worth noting the Fed's official statement also pointed to elevated inflation from energy prices as a reason for tightening now. The benign medium‑term picture, then, rests heavily on productivity continuing to deliver.
What it means for Australian investors
US interest rates set the tone for global markets, so this outlook matters well beyond America. A world where US inflation is contained and the rate cycle is near its peak is generally a more supportive backdrop for shares and bonds over the medium term. It can also influence the Australian dollar and the returns available on income assets.
That said, the near term still carries risk. Inflation is elevated today, energy prices are volatile, and the benign path depends on productivity gains holding up. A few sensible principles apply:
- Do not position a whole portfolio around a single forecast, even a central bank's.
- Stay diversified across shares, bonds and other assets so no one outcome dominates your result.
- Match your investments to your timeframe and tolerance for risk.
- Review your strategy with a professional who watches both global and local drivers.

Frequently asked questions
What is the US interest rate outlook after the September 2026 Fed meeting?
The Fed raised rates by 0.25% to a range of 3.75% to 4.00% and its projections point to one more hike before rates peak near 4.1%. The US interest rate outlook then shifts to gradual cuts from 2028, easing toward a longer‑run level of around 3.2%.
What is the Fed's Summary of Economic Projections?
The SEP is a quarterly report in which Federal Reserve officials publish their forecasts for growth, unemployment, inflation and interest rates. Investors watch it closely because it signals how the central bank expects policy to evolve.
Why would the Fed cut rates if it is hiking now?
The current hike is aimed at bringing today's elevated inflation back to target. Once the Fed is confident inflation is under control, its projections show it easing rates gradually, which is why a near‑term rise and later cuts can appear in the same outlook.
How do US interest rates affect Australian investors?
US rates influence global borrowing costs, share valuations, bond yields and the Australian dollar. A stable, contained US rate outlook is generally supportive for markets, while surprises in either direction can drive volatility here at home.
What is driving this stronger, lower‑inflation outlook?
Morgans' view is that rising productivity, led by large‑scale investment in data centres and AI, is allowing the US economy to grow strongly while inflation still falls. Sustained productivity gains are central to the outlook holding.
The bottom line
The latest US interest rate outlook is about as constructive as investors could reasonably hope for: solid growth, low unemployment, inflation heading back to target and a rate cycle near its peak. The key risk is whether the productivity story that supports it continues to deliver. As always, the smart move is to understand the drivers and build a strategy that can handle a range of outcomes.
