Market Overview
The inflation repricing goes global, and Australia imports it.
The week's defining fact is where the repricing came from. Australian three-year yields rose ↑25 bps to 5.00% in a week when the domestic data was uniformly poor. Westpac consumer confidence fell ↓5.2% in September to 84.4, reversing a ↑6.0% gain. NAB business conditions fell from +4 to -1, their first negative reading in this dataset, and confidence slipped to -8. Consumer inflation expectations remained stuck at 4.9%. Australian bonds did not reprice on Australian news. They repriced because they are priced in a global market, and three things happened offshore.
First, US producer prices accelerated sharply. Final demand PPI rose to ↑5.4% YoY against ↑5.3% expected, up from a revised ↑4.8% YoY, with the core measure at ↑4.6% YoY from ↑4.3% YoY. Producer prices sit upstream of consumer prices, so this signals pipeline pressure rather than current inflation. The consumer data was better behaved, with headline CPI holding at ↑3.4% YoY and core easing to ↑2.4%. The pipeline is heating while the outlet cools, and we do not yet know which resolves.
Second, the ECB raised rates — the deposit facility ↑25 bps to 2.50% and the main refinancing rate to 2.65%, both as expected. Until this week higher-for-longer was a market forecast; it is now an observed central bank action. The ECB also tightened into improving growth, with euro area Q2 GDP revised up to ↑1.2% YoY and investor confidence firming.
Third, and least discussed, China stopped exporting disinflation. Chinese producer prices rose to ↑3.8% YoY against ↑3.6% expected, consumer prices to ↑0.8% YoY from ↑0.5% and core to ↑1.0%. For two decades Chinese factory-gate deflation was a persistent disinflationary force in global traded goods that Australian and US inflation benefited from without anyone arranging it. That channel has reversed, and with exports ↑25.0% YoY and imports ↑28.2% this is not weak demand but a genuine change in the cost of the goods the world buys. Add Brent up ↑8.65% to US$104.61 and the picture is complete.
The dominant narrative is therefore a change in the inflation regime rather than another data point within it. Energy, Chinese producer prices and US pipeline costs moved in the same direction at once, and a central bank acted. That is why bond markets repriced the entire curve rather than the next meeting, and why Australia was carried along despite domestic evidence pointing the other way.
For Australia this is the uncomfortable combination, and we need to revisit a view. Three weeks ago we described Australia as drifting toward a stagflationary configuration. Last week we withdrew that after the GDP beat. This week we raise it again, and we should be transparent that this is the second revision in three weeks. The data does not contradict itself: GDP measured the June quarter and was backward-looking, while confidence surveys are September readings and forward-looking. Surveys lead, national accounts lag, and both can be right about different moments. What has changed is the mechanism. The earlier concern was domestic demand keeping core inflation elevated; the concern now is an external shock arriving as domestic confidence deteriorates. That is the harder version, because the RBA cannot influence the price of oil or Chinese factory-gate prices — its only instrument works on domestic demand, which is already weakening.
Oil – Brent rose ↑8.65% to US$104.61 per barrel, following a ↑7.80% rise the previous week, for a two-week gain of roughly ↑17% and a twelve-month gain of ↑57.6%. With the conflict in the Middle East persisting and no apparent off-ramp, energy prices are unlikely to come off any time soon, remaining a persistent inflation and growth headwind.
Equity Markets
There was nowhere to hide — every major market we track finished lower, led down by the Hang Seng at ↓3.30% and the ASX 200 at ↓2.94%.
Australia was the worst performer in the developed world, for a reason we have flagged for five consecutive weeks. The equity risk premium had compressed to roughly 16 bps entering the week, leaving no valuation cushion between Australian shares and government bonds, so when the ten-year rose 19 bps there was nothing to absorb it. The market with the thinnest risk premium has the most to lose when the discount rate moves. We would stress this was an observation about the absence of a cushion rather than a forecast of a shock: we did not predict the repricing, only that Australian equities had no protection if one arrived.
The arithmetic has worsened again, and the twelve-month record has crossed an important line. The ASX 200 trades on 18.3x forward earnings for an earnings yield of 5.47% against a ten-year bond at 5.37%, an equity risk premium of approximately 10 bps and a fifth consecutive week of compression from 33 to 27 to 18 to 16 and now 10. Over twelve months the index has delivered a price return of -0.72%. With a 3.53% dividend yield the total return is roughly +2.80% before franking, against a cash rate of 4.35% that carried no volatility at all. Franking improves the comparison for domestic investors and we would not dismiss it, but the plain statement is that an investor who accepted full Australian equity risk for a year has been paid less than one who did nothing.
US markets held up comparatively well because core CPI eased to ↑2.4% YoY, so US equity investors received a better consumer inflation signal than bond investors received from producer prices. Even so, the NASDAQ at 29.6x against a ten-year Treasury at 4.97% is the tension we flagged last week, and it has begun to resolve against valuations. Dispersion remains wide — the S&P 500 on 21.3x, the ASX 200 on 18.3x, the STOXX on 15.4x and the Hang Seng on 11.4x — but the Hang Seng cautions against treating cheapness as an entry signal: already the cheapest major market, it fell furthest this week and is down 4.91% over twelve months.
Fixed Income & Credit
Australian government bonds and the RBA – three-year yields rose ↑25 bps to 5.00%, five-year ↑25 bps to 5.04% and ten-year ↑19 bps to 5.37%, with swaps in line. Every one of those levels is a one-year high, as is three-month BBSW at 4.67%. The curve bear-flattened to 37 bps from 43 bps, and short yields rising faster than long yields is the classic signature of an inflation scare rather than a growth upgrade.
The three-year now sits 65 bps above the cash rate and BBSW 32 bps above, up from 24 bps, so market pricing embeds a meaningful expectation of tightening. The RBA did not meet and the cash rate is unchanged over the month, quarter and year, however futures are now pricing a cash rate at 5.00%, suggesting almost three hikes left in the cycle (not our base case). We will not forecast, but we will describe the position plainly: the RBA faces an imported inflation shock it cannot influence arriving as domestic confidence deteriorates sharply. That is the hardest configuration a central bank can face, and it is why we would caution against positioning aggressively for either outcome — pricing has travelled a long way in one direction, which makes it vulnerable in both.
US Treasuries – the two-year rose ↑26 bps to 4.63% and the ten-year ↑18 bps to 4.97%, flattening the two-to-ten-year curve to 34 bps from 42 bps and reversing the prior week's steepening. The front end led because that is where policy expectations live. We flagged last week that a bear steepening said growth is holding while inflation repriced further out; this flattening says attention has moved back to near-term policy. Against it, core CPI easing to ↑2.4% and NY Fed inflation expectations easing to 3.58% are genuine counter-evidence. Producer and consumer prices point in opposite directions, and we would not pretend to know which wins.
Investment grade credit and Australian bank paper – this was the reassuring part of the week, with floating rate credit widening 1.1 bps to 61.5, fixed rate 0.6 bps to 79.5, major bank senior 2 bps to 70, and Tier 2 unchanged at 127. Credit barely moved while government yields rose ↑20 – 25 bps and equities fell around three per cent, and the reason is worth explaining carefully. A credit spread compensates for the risk that a borrower does not repay, and nothing this week suggested rising default risk: job advertisements rose 2.5%, US initial claims held at 206,000 and continuing claims fell. What repriced was the risk-free rate, the price of time and expected inflation, which is a different question entirely. This is the clearest illustration in months of why credit and government bonds are distinct instruments rather than variations on the same one.
One caution. Senior spreads are 7 bps wider over the month and now sit 7 bps above their one-year tight, so the drift is persistent rather than absent, and credit may be lagging the rates repricing rather than immune to it. The subordination premium compressed further to 57 bps against a one-year average near 64 bps, reinforcing our existing view: at approximately 6.56% all-in, Tier 2 is attractive in absolute terms, but the case rests on that absolute yield rather than on relative value.
What this means for income-focused investors – the arithmetic improved again, and for the right reason. Floating rate credit now yields approximately 5.28%, major bank senior 5.99% and Tier 2 6.56%, levels that rose ↑8 – 24 bps over the week driven almost entirely by higher base rates rather than wider spreads. Income investors were paid more without taking more credit risk.
The comparison we would put on the table is floating rate credit at 5.28% against an ASX 200 dividend yield of 3.53%: credit pays roughly 175 bps more than the share market, ranks ahead of equity, and carries a fraction of the volatility — as this week showed, with shares down 2.94% while spreads moved a single basis point.
Outlook
The central case. An inflation regime change is underway, driven by energy, the reversal of China's disinflationary exports and accelerating US producer costs. Developed market policy rates stay at or above current levels, with the ECB having already moved. Growth globally is adequate while Australia deteriorates in forward-looking measures. We attach the highest probability to this scenario while acknowledging the evidence within it is genuinely conflicting.
Key risks. The one we weight most heavily for domestic portfolios is imported stagflation in Australia, for the reasons set out above. Second, the equity valuation cushion is gone — with the risk premium at roughly 10 bps and the ten-year at a one-year high, nothing stands between Australian equities and a further de-rating if yields rise again.
Key opportunities. Income is the clearest, and it improved this week through higher base rates rather than deteriorating credit quality. Government bonds at one-year-high yields now function as genuine portfolio insurance rather than a drag, and equity valuation dispersion remains wide — though this week was a reminder that cheapness alone is not a catalyst.
Central banks. The ECB tightened into improving growth, which is the comfortable version. The Federal Reserve faces producer prices at ↑5.4% against core consumer prices easing to ↑2.4%, conflicting evidence we would not predict a response to. The RBA faces the hardest position of the three.
Inflation and growth. Inflation risk has shifted higher and the source has broadened: energy is now joined by China, and if the withdrawal of that long-standing disinflationary subsidy persists it matters more than any single central bank decision, because it changes the starting point from which all of them must work. Growth is adequate globally — Europe revised up, the US labour market stable, Chinese trade strong — leaving Australia the outlier on the downside, a reversal of the picture we described only last week.
What would change the narrative? A sustained retreat in crude, though we set that bar at US$85 last week and the price moved twenty dollars the other way, so we would treat any single threshold with humility. A US producer price reading that fails to pass into consumer prices would reverse the front-end repricing quickly. And an Australian labour market that confirms the confidence surveys would flip the RBA conversation back toward cuts and reward duration sharply from a one-year-high starting yield..
