The Week Inflation Gave Markets Permission to Breathe | Week Ending 15 August 2026

It was the kind of week that reminds you markets are two things at once: a forward-looking pricing machine, and a news-driven anxiety machine. Sometimes both show up in the same five days.

How the Week Unfolded

Monday and Tuesday brought mild selling. US-Iran tensions in the Strait of Hormuz pushed Brent crude above US$89 a barrel — a level not seen in months — and the broad indices slipped for two consecutive sessions. Tech diverged. Energy stocks surged. The mood turned defensive.

Then Wednesday arrived with the July CPI print.

Headline inflation came in at 3.4%, with the monthly read a quiet +0.1%. Core CPI — the number the Fed actually watches — rose 0.2% for the month. Neither figure was a surprise. But “not a surprise” was exactly what markets needed. By Wednesday’s close, the S&P 500 and Nasdaq had clawed back into the green. The Dow, dragged by energy-sensitive industrials, stayed slightly lower.

Thursday was the breakout session. Producer prices came in flat — a reading that effectively told the market the September rate hike was dead. The S&P 500 hit a new all-time high, gaining 0.7% to close at a fresh record. The Nasdaq added 0.8%. Oil reversed, giving back a chunk of its earlier gains as the geopolitical noise dialled back.

Friday was a modest consolidation. The S&P slipped 0.2%, the Nasdaq gave back 0.3%, and the Dow dipped in line. Weaker-than-expected July retail sales data added a note of caution, but the pullback was not a reversal — just the market pausing at altitude. Importantly, it was still the third consecutive weekly gain for the S&P 500 and Nasdaq (the Dow lagged and finished the week lower).

What It Means

The inflation-to-rate-cut story that’s dominated 2026 is still intact, but it’s running on diminishing margin. The market has largely priced in a “soft landing” scenario. What it hasn’t priced in is any serious escalation of the Iran/oil situation — and that’s the residual risk.

Brent crude at $89 is not a crisis. Brent crude at $95+ starts to reintroduce cost-push inflation into the picture, which would complicate the Fed’s next move considerably. Watch the Strait of Hormuz.

On the earnings side, reports were broadly constructive. No blow-ups. Tech pulled its weight midweek before fading Friday. The consumer discretionary names largely held, suggesting the American consumer hasn’t cracked — yet. The soft retail sales print on Friday is a reminder that this remains a watchpoint.

The Aussie Lens

For Australian investors holding unhedged US equities, this was a mixed week in real terms. The AUD held relatively steady against the USD, meaning currency wasn’t a meaningful headwind or tailwind. The equity gains from Thursday’s record session translated fairly cleanly into AUD-equivalent returns for Aussie holders.

The bigger watch: if the Fed stays on hold while the RBA navigates its own inflation dynamics, the interest rate differential between the US and Australia narrows. That tends to apply modest upward pressure on the AUD — which, all else being equal, works against unhedged US exposure. Not dramatically. But it’s the direction of travel worth tracking.

Sectors to Watch Next Week

• Energy — Iran headlines remain the swing factor. If tensions ease, expect a reversal.
• Tech/AI — Mega-cap earnings season is winding down, but the AI infrastructure spend thesis is still being tested.
• Consumer — Retail earnings begin rolling through next week. Post-CPI and after the soft sales print, these will be closely watched for margin signals.
