Investors face a pivotal week as US inflation, the ECB rate decision and Australian data test expectations for further global monetary tightening.
United States (US) equity markets are on track for a second consecutive week of gains. The bulk of the advance came after Federal Reserve (Fed) Governor Christopher Waller sounded dovish and took some of the heat out of rate hike concerns.
Waller noted that recent inflation data had improved and that, if incoming data continued to point in that direction, he would be inclined to hold the federal funds rate at the 16 September meeting. This saw the probability of a September Fed rate hike fall to about 50% from 68% earlier in the week. Investors also took some comfort from the fact that nothing in the latest Middle East flare-up has warranted fresh US strikes on Iran since Wednesday.
Closer to home, ASX 200 is trading 70 points (-0.70%) lower on the week and is set to lock in a third week of losses in the past four. The decline followed this week's resilient second quarter (Q2) gross domestic product (GDP) print, with annual growth at 2.1%, coming on the heels of the prior week's sticky trimmed mean inflation report. That combination has pushed up the probability of a fourth Reserve Bank of Australia (RBA) rate hike this year.
Together with falling housing prices and profit-taking in the big mining stocks, it has been too much for the index to withstand.

Last month the Westpac-Melbourne Institute Consumer Sentiment Index rose to 88.9 from 83.9 in July, the highest reading since March. The lift was concentrated among mortgage holders after the RBA held the cash rate at 4.35% on 11 August, following three hikes earlier in the year. Despite the bounce, it was still viewed as a weak result.
'While consumers are feeling less pessimistic than last month, pessimists still outnumber optimists, especially about their current finances. The improvement in forward-looking views was also much less pronounced than for the questions covering current conditions. This suggests that pervasive uncertainty, including about the Middle East, is still weighing on sentiment to some extent.'
September's print must digest a much harsher backdrop. Last week's 3.6% trimmed mean inflation reading and this week's resilient Q2 GDP print, with annual growth at 2.1%, have pushed up the odds of a fourth rate hike this year while falling housing prices continue to dominate the headlines.
That is likely to provide a direct hit to sentiment and, in particular, mortgage rate expectations, which is usually what moves this survey around. A drop back into the low 80s is expected.
The Australian interest rate market is set to end this week pricing in 16 bp, or around a 66% chance of a 25 bp rate hike for the 29 September RBA Board meeting, with a full 25 bp hike priced for the RBA's 3 November Board meeting.

Last month China's annual headline CPI slowed to 0.5% in July from 1.0% in June, a six-month low and below the 0.8% expected. Core inflation, excluding food and energy, eased to 0.9%, also a six-month low.
The decline has raised concerns that deflationary risks are re-emerging. Those concerns sit with policymakers tightening fiscal policy as export growth strengthens. That is landing while the property market remains a heavy drag and household deleveraging has intensified. In a nutshell, if households keep paying down debt at this pace and the fiscal squeeze holds, deflationary pressure can come back.
August is expected to show a rebound with estimates clustered around 0.9% YoY, driven by oil's rise during August.

At its June meeting, the ECB delivered a 25 bp hike, the first since 2023, lifting the deposit rate to 2.25%. In the updated staff projections, headline inflation on the Harmonised Index of Consumer Prices (HICP), the official euro area measure and the one the ECB targets at 2% over the medium term, was revised higher, largely on a higher assumed path for energy prices and their indirect effects on food, goods and services.
At the 23 July meeting the Governing Council held all three key rates steady. ECB President Lagarde said the energy outlook was still close to the June baseline and well above pre-conflict levels: 'Uncertainty remains high and the full inflationary impact of the energy shock has yet to play out. We are therefore closely monitoring the intensity and duration of the shock, as well as its indirect and second-round effects.'
Earlier this week annual HICP inflation accelerated to 3.3% in August from 2.9% in July, the highest since September 2023, driven by energy inflation that jumped to 14.3%. Markets have fully priced a 25 bp hike next week to 2.50% and are also fully priced for a second 25 bp hike at the ECB's December meeting.

July's CPI report showed the annual inflation rate slowing for a second month to 3.4% from 3.5% in June, in line with expectations and further below the 4.2% high reached in May 2026. Core CPI rose 0.2% after a flat June, taking the annual core rate down to 2.5% from 2.6%, matching forecasts and the softest reading in five months.
Last week Fed Chair Kevin Warsh sounded hawkish in his speech at Jackson Hole, noting that the Fed's 2% inflation target is not up for negotiation and that recent Personal Consumption Expenditures (PCE) and CPI readings were better than expected, but they do not tell him that underlying trends have meaningfully improved.
August's figures will be scrutinised for evidence of whether that core moderation is sustained, or whether energy starts leaking into the rest of the basket. Consensus expects core inflation to rise about 0.2% MoM, taking the annual core rate to 2.4%. Headline CPI is expected to remain at 3.5% YoY.
A hotter print, for example core inflation back at 0.3% MoM, would likely push hike probabilities higher again ahead of the 16 September Federal Open Market Committee (FOMC) meeting. The US rates market is set to finish this week pricing 13 bp of hikes for the Fed's 16 September meeting and 57 bp of hikes between now and June 2027.
