AI Safety Takes Center Stage While Central Banks Follow Through on Their Inflation Fight

For the week ending 18 September 2026

As of midday Friday, global equities were modestly lower on the week as a surge in bond yields — driven by persistent inflation and hawkish central banks — weighed on risk sentiment. The US 10-year Treasury yield briefly surpassed 5% for the first time in nearly three years, while the 2-year yield reached its highest level since mid-2024, reflecting expectations for additional Fed rate hikes. The price of a barrel of West Texas Intermediate crude oil rose roughly $2 on the week to $102.10, with elevated energy costs adding to inflation concerns. Volatility, as measured by futures contracts on the CBOE Volatility Index (VIX), eased slightly to 15.31 from 15.84 a week ago, even as equities struggled for direction.

MACRO NEWS

Calls to slow AI development intensify

Over the weekend, several prominent AI and tech leaders — including Dario Amodei, Sam Altman, and Elon Musk — called to slow the pace of development of advanced AI models on the grounds of safety, urging the industry to take the necessary time to develop models responsibly. These appeals were met by pushback and scrutiny from Nvidia CEO Jensen Huang, Meta’s Mark Zuckerberg, and US Vice President JD Vance, who argued that market forces are already sufficient, new regulation is not necessary, and any self-limitation could damage growth and set back US AI global leadership ambitions. Chips stocks sold off sharply on Monday in response, with the Philadelphia Semiconductor Index down ~6% before recovering most of those losses later in the week. Conversely, software and cybersecurity stocks, typically seen at risk of AI disruption, rallied on Monday in response to the heightened debate.

Energy prices surge in fallout from drone attack

Drone strikes launched from Iraq’s Maysan province struck Saudi Arabia’s East-West Pipeline on September 10, forcing a shutdown of the kingdom’s key crude export route that bypasses the Strait of Hormuz. Brent crude initially surged 3.7% to above $108 per barrel before retreating to ~$102 as Saudi Arabia rerouted exports and targeted partial pipeline restoration within days. Iran-backed militias are suspected of the attack, and markets have partially stabilized as diplomatic efforts are underway to contain further escalation, but geopolitical risk remains elevated.

Fed raises policy rate, signals more to come

Citing a booming economy and inflation above the 2% target, the FOMC unanimously voted to raise the benchmark Federal funds rate by 25 basis points, bringing the target range to 3.75%–4.00%. This marks the first increase since 2023. The majority of Fed officials expect one additional rate hike by year end, with four members anticipating two more hikes. Stocks initially rallied on the decision but reversed course as Warsh’s commentary was interpreted as hawkish, with the S&P 500 closing Wednesday at its lowest level since July and the Dow falling 1.2%. Short-dated Treasuries underperformed — the 2-year yield hit its highest level since 2024 — while the dollar climbed broadly. Notably, investment-grade credit spreads tightened in both Asia and the US, as markets interpreted the Fed’s pivot as a credible inflation-fighting signal.

Bank of England holds rates steady, for now

The Bank of England’s Monetary Policy Committee voted 6–3 to hold the bank rate at 3.75% but signaled that a future hike may be warranted if geopolitically driven inflationary pressures intensify. Governor Andrew Bailey stated in prepared remarks that the global energy shock has had a “quite subdued” pass-through into inflation so far, but he also cautioned: “the longer these high energy prices go on, the more difficult this becomes.” In a surprise move, the BOE also announced that it has decided to scrap plans to sell long-dated gilts as part of its quantitative tightening program. This triggered a significant gilt market rally, with 30-year gilt yields initially falling 12 basis points to 5.74%. 

Bank of Japan raises rates in split decision

In a split decision, the Bank of Japan raised its benchmark interest rate by 25 basis points to 1.25% and signaled future tightening to prevent inflation from overshooting its 2% target. While the rate hike was largely priced in, the degree of dissent among policymakers was not, creating uncertainty around the pace of additional increases. The yen weakened following the announcement as markets appeared disappointed that Governor Ueda did not strike a more hawkish tone.

QUICK HITS

Canada’s August CPI held steady at 3.0% year over year, in line with expectations, with the Bank of Canada’s core measures averaging 1.95% (near the 2% target). Underlying inflation ex gasoline accelerated, however, signaling persistent price pressures. With the Bank of Canada holding its policy rate at 2.25% and warning it may hike if elevated energy costs broaden, the report presents a cautiously mixed outlook for Canadian monetary policy.

The UK labor market showed further signs of softening, with payrolled employees falling by 26,000 in August — well below expectations of a 5,000 decline. The unemployment rate held steady at 4.9%, near a five-year high.

The US Senate failed to advance the Digital Asset Market Clarity Act in a 49–50 procedural cloture vote — well short of the 60 votes required — over unresolved ethics and national security concerns. Bitcoin fell more than 5% during the vote before recovering, while crypto-related stocks remained under pressure, with Coinbase and Robinhood posting notable declines.

Treasury Secretary Scott Bessent testified before the House Financial Services Committee on September 15, defending the US role in a coordinated yen intervention as being in America’s national interest, arguing that a stronger yen boosts US export competitiveness and reduces Japan’s need to sell US Treasuries to fund its own currency operations. Bessent characterized the US contribution to the intervention as “nominal,” and markets largely shrugged off the testimony.

Intel shares rallied mid-week amongst reports that they are in talks with SK Hynix about a deal that would see it manufacture memory chips in the US for the first time — potentially leasing part of Intel’s Ohio facility or forming a joint venture with major cloud firms.

US retail sales surged +1.2% month over month (m/m) in August, the largest monthly gain in five months and well above the +0.8% consensus estimate, driven by broad-based strength across autos, gasoline, and online retail. The control group, a key GDP input, rose +1.4% against a +0.5% estimate, reinforcing the picture of a resilient American consumer.

US industrial production was flat in August 2026 (0.0% m/m), missing the consensus estimate of +0.3%, as a 0.3% decline in factory output offset gains elsewhere. Year-over-year growth held at +1.42%, while capacity utilization remained unchanged at 76.3%, signaling muted inflationary pressure from the industrial sector.

UK retail sales surged 0.5% m/m in August, far exceeding the consensus estimate of -0.2% and fully reversing July’s decline, driven by warm weather, strong online retail, and promotional activity. The better-than-expected print pushed the annual rate to +2.4%, suggesting UK consumer spending remains resilient despite elevated energy costs and inflation.
