MARKET AT 7
Good evening. AI's fingerprints were all over markets today: pushing US tech stocks to a fresh record, pushing Australian inflation higher according to the country's own central banker, and raising real questions about whether it's also inflating a bubble.
In tonight's newsletter:
Bullock says AI data centre boom is adding to inflation
Wall Street closes at record highs, rally flows into Asia
Oil drops below $100 a barrel on US-Iran diplomacy hopes
Bitcoin whipsaws as Binance faces Iran sanctions probe
RBNZ governor warns oil prices could push inflation higher
Bullock says AI data centre boom is adding to inflation
RBA governor Michele Bullock told a Committee for Economic Development Australia lunch in Sydney on Tuesday that the global rush to build AI data centres is "adding" to Australia's demand-driven inflation problem, because the technology's supply-side productivity gains haven't shown up yet while its construction spending already has. She said unemployment sitting between 4.5% and 5% would probably "take enough heat out of the labour market" to ease inflation pressure, and flagged that a disorderly unwind of what "might be" an AI bubble could hit the financial system. Her comments land a week before the RBA board meets on 29 September, with markets pricing hike odds above 85%. Source: ABC News, 22 Sep 2026 → · Source: Capital Brief, 22 Sep 2026 →
OUR TAKE:
A central banker saying unemployment needs to rise a little to fight inflation is about as blunt as this language gets. Bullock isn't hedging anymore. She's telling parliament and business lunches the same hawkish story on repeat.
Wall Street closes at record highs, rally flows into Asia
The Nasdaq Composite jumped 2.26% to 27,122.09 on Monday, its first record close since June, as AI chipmakers rebounded from last week's sell-off. The S&P 500 rose 1.49% to 7,764.70 and the Dow added 0.71% to 52,048.83, the Washington Post and Yahoo Finance report, with falling oil prices and easing Treasury yields also lifting sentiment. The rally carried into Tuesday's Asian session, pushing Taiwan's market to a record high and South Korea's KOSPI up as much as 2.3%.

OUR TAKE:
Last week's AI sell-off looked like it might be the start of something bigger. One record session later, traders have decided it wasn't.
Oil drops below $100 a barrel on US-Iran diplomacy hopes
Brent crude briefly fell below $100 a barrel in early Tuesday trade, its lowest level in weeks, before steadying back near $101, as traders weighed progress toward US-Iran diplomacy at this week's UN General Assembly alongside a partial recovery in Saudi Arabia's crude exports, ABC News and Yahoo Finance report. Satellite data shows Saudi loadings from the Persian Gulf have picked up, suggesting the kingdom is shifting exports back through the Strait of Hormuz, even though Iran maintains the strait itself stays closed until Washington meets its conditions. Barclays still says prices could jump another 50% if the standoff drags on. Source: ABC News, 22 Sep 2026 → · Source: Yahoo Finance, 22 Sep 2026 →
OUR TAKE:
A price drop doesn't mean the crisis is over, since the strait Iran is blockading hasn't reopened. What eased today was the market's fear that it never will.
Bitcoin whipsaws as Binance faces Iran sanctions probe
Bitcoin fell 1.4% to about $85,730 by Tuesday afternoon in Australia, pulling back after climbing more than 6% over the prior 24 hours on a wave of short covering and fresh spot ETF inflows, CoinDesk and ABC News data show. The reversal came as US federal prosecutors confirmed they're investigating whether crypto exchange Binance violated Iran sanctions by failing to prevent certain trading on its platform, Reuters and Bloomberg report via ABC News. Binance says it has "zero tolerance" for sanctions violations and is cooperating with investigators. Source: ABC News, 22 Sep 2026 → · Source: CoinDesk, 22 Sep 2026 →
OUR TAKE:
A short squeeze can push bitcoin up in a day. A federal sanctions investigation into the world's biggest exchange is the kind of headline that can send it straight back down.
RBNZ governor warns oil prices could push inflation higher
eserve Bank of New Zealand governor Anna Breman said Tuesday that if recent gains in oil prices persist, they would push inflation "somewhat" higher than the bank's own forecast, even as she expects the broader economic recovery to strengthen through exports and household spending, FXStreet reports. New Zealand's cash rate sits at 2.75% after this month's quarter-point hike, and inflation ran at 4.1% in the June quarter on Middle East-driven fuel costs, with the RBNZ due to review the rate again in October.

OUR TAKE:
New Zealand and Australia are being squeezed by the same oil shock from opposite ends, one bank already hiking, the other about to. Neither has much room left before higher rates start doing real damage to growth.
QUICK HITS
CBA joins NAB in tipping a September RBA hike, as fixed mortgage rates jump. Commonwealth Bank brought forward its call for the next RBA rate rise to September, from November, citing persistently high inflation and oil prices, while also lifting fixed mortgage rates for new customers by up to 0.48 percentage points, ABC News and Canstar data show. Sixteen lenders have now raised fixed rates this month. Our take: the banks aren't waiting for the RBA to confirm anything. They're pricing in the hike and passing the cost straight to borrowers.
Australian household spending slows as fuel costs bite. CBA's Household Spending Insights index rose just 0.1% in August, down from 0.6% in July, with annual growth easing to 4.7% from 5.2%, as households diverted more of their budgets to petrol and diesel prices sitting at multi-month highs, ABC News reports. Our take: this is what a rate hike is supposed to do before it's even delivered. Households are already pulling back.
Trump and Xi head into a high-stakes Washington summit Thursday. President Trump will host Chinese leader Xi Jinping in Washington on 24 September, the first visit by a Chinese leader to the US capital in more than a decade, with trade, AI safeguards and the Iran war on the agenda, according to Bloomberg and CSIS. Expectations for a major breakthrough are low, with analysts framing regular leader-level contact as the real marker of progress. Our take: nobody's expecting a grand bargain this week. Just showing up and talking normally now counts as a genuine milestone in this relationship.
