Hi, I'm Alex Kersley, portfolio manager here in Sydney, and this is Market Week in Review for the week ending 18th of September, 2026. So, this week was really about one thing, the Federal Reserve. So, we had the Fed meeting where they raised interest rates as was largely expected by the market. The key interest and key focus heading into this meeting was whether this was going to be a a one-and-done kind of interest rate increase or a start of a protracted interest rate increasing cycle. I think that it seems that the Fed is largely landing on the a couple of interest rate hikes, but not a protracted. So, when we look at the dot plots, which is the projection of interest rates by each member, uh we see one more rate hike in December. Uh and then a hold from there. And that is in line with our view. So, we think that we'll probably see another interest rate hike before December, and they'll be on a protracted pause. And there are a couple of really important differences to 2021-2022 and the inflation that we saw then. So, there is a bit of a pick-up of inflation pressure at the moment. A lot of that is being driven by what is happening with energy prices around the Middle East conflict. But when we look more broadly, we don't see the same sort of inflationary pressures that we saw in '21-'22. And there are two real dominant drivers there. The first is the wages story. So, the labor market has been resilient as we've been highlighting, and it's actually showing some signs of improvement. But we aren't seeing wage pressure picking up at this point, and so we think that's a pretty healthy I pretty friendly environment for um not a great deal of inflation pressure. And the second is the housing market. The housing market is still uh quite soft in the US. And so, those two dynamics aren't going to lead to um sustained inflation pressure in our opinion. And so, we should see a slow disinflation trend coming through over the next 12 months. That we'll see the Fed raise interest rates again in December, and then be on hold as that disinflation starts to come through. From a market's perspective, we think that US government bonds look attractive from a valuation perspective right now given the re-rate or the re-pricing of interest rates, but we haven't seen any signs that sentiment has become dislocated that would really represent a tactical opportunity to add to government bonds. We also had the Bank of England meeting where they kept rates unchanged. Um we think that we're likely on a path of just protracted holds from the Bank of England. The economy there is still under some pressure. There's always that inflation pressure from the Middle East and energy prices, but the economy is still quite soft. Finally, it was uh the next bit is in China where we have continued to see this softening in the economy. And the most recent data put we got this week was the credits numbers. So, we see a continued softness in credit demand both from businesses and from individuals. So, if you think that household demand for for credit is largely in the form of mortgages, Chinese house market is still quite soft. And so, there isn't much appetite to be going out and buying new property right now. And on the business side, they're taking their cue from the consumer confidence and the broader economic trends. And there isn't a huge amount of demand for capital expenditure or expansions expansion plans outside of a couple of sectors related to high-tech. And so, that remains fairly soft. Local government side of bond financing has been still a bit of a a bulwark for the credit numbers, but it isn't enough right now. And so, we think that China's going to remain this world where growth is not very strong. We're looking at like 4.5% GDP thereabouts, but it hasn't materially weakened enough to see the government come out aggressively with stimulus. And if we stay in this world where likely to see a continuation of that 4.5 to 4% GDP growth out of China. I think just the final bit is on equity markets. So, point-to-point where we're calling this as a Thursday close. US global equity markets look relatively unchanged. We had some weakness earlier in the week and then a rebound on Thursday. And think I think it's really important is to go from a cycle value and sentiment, which is our framework at Russell, how we're thinking about global equity markets right now. Uh it's from a cycle perspective, we think the economy is quite resilient and it's going to remain that way. Uh and importantly, corporate earnings uh are even stronger. So, we've seen really robust corporate earnings around the world over the last 6 months. Uh profit margins are improving. We have this wave of AI capital expenditure. And we're starting to see early signs of that AI is starting to improve business uh operations. So, that should further improve profit margins. Uh valuation for equities uh they aren't cheap right now. Uh US is still a little bit more expensive than the rest of the world, but they aren't at points that we would describe as extremely expensive. So, not a huge headwind in the short term. So, that leaves us with sentiment. And our sentiment models are still relatively close to neutral. We aren't seeing any signs of euphoria or haven't seen any signs of euphoria over the last couple of months. Uh we're a long way away from panic, obviously. The market is is still quite um robust. Um but for that with that combination of cycle being supportive, valuations not being very expensive or extremely expensive, and sentiment being fairly close to neutral, that's still a fairly constructive backdrop for risk. And so, we think that leaning into equity markets a little bit is still a a prudent place to be. With that, thank you for your time uh and look forward to speaking to you next time.

Key takeaways

  • Hotter U.S. inflation keeps another Federal Reserve rate hike in play
  • Renewed concerns around AI investment and financing pressure weighed on technology stocks
  • Falling Treasury yields despite hotter inflation highlight the market’s flight to safety

Hotter inflation keeps the Fed in focus

Our Global Chief Investment Strategist Paul Eitelman sees markets caught between two competing forces this week: hotter U.S. inflation and renewed concerns around the artificial intelligence trade.

Both consumer and producer price inflation for September came in above expectations. Core PCE inflation is now tracking at roughly 3.1% year-over-year, a level that has remained stubbornly elevated through much of 2026.

That persistence helps explain why the Federal Reserve raised rates at its September meeting and keeps the possibility of another hike firmly on the table.

As Eitelman explains, the question may now be less about whether the Fed tightens again and more about when. Policymakers could move at the end of October or wait until the December meeting, with upcoming Fed communication likely to provide more direction.

There is more behind the inflation story than a single hotter reading. Persistent price pressures leave policymakers balancing the need to contain inflation against the risk that additional tightening weighs too heavily on growth and financial markets.

AI concerns outweigh the inflation story

The bigger market reaction this week came from renewed questions around the AI investment cycle.

Investors are increasingly scrutinizing whether the enormous levels of capital being committed to AI infrastructure are generating sufficient returns. At the same time, higher interest rates are drawing greater attention to leverage and financing risks among some of the more indebted companies tied to the AI buildout.

Those concerns translated into meaningful selling pressure.

Through Thursday’s close, the Nasdaq 100 Index was down roughly 3%, while the Philadelphia Semiconductor Index had fallen around 8%. South Korea’s KOSPI Index, another market with concentrated AI exposure, declined close to 16%.

As Eitelman notes, the reaction in fixed income was particularly telling. Hotter inflation would normally be expected to push Treasury yields higher. Instead, the 10-year Treasury yield fell roughly 16 basis points as investors moved toward safer assets amid the risk-off move in technology.

That suggests concerns around AI and market positioning outweighed the immediate inflation signal, at least for this week.

Midterms move closer into view

Investors are also beginning to look ahead to the U.S. midterm elections on November 3.

Russell Investments’ recent analysis examines how different congressional outcomes could affect policy and markets, as well as what political scrutiny of the AI data center buildout could mean for investors.

For Eitelman, the broader message is to look beyond short-term political headlines and focus on the policy and economic backdrop that ultimately drives markets.
