Market briefing — 25 September 2026

AI-generated market briefing from 25 September 2026. It reflects information available at the time and has not been updated retrospectively.

1. Bond anxiety escalates; markets start talking about 6%

The global bond sell-off continued, with long US yields near two-decade highs. After the 10-year yield passed 5%, investors began discussing whether 6% could be the next pain threshold. The dollar was heading for a gain of about 1% on the week, while Asian stocks had so far held up relatively well. Source: Reuters

Why it matters: This is currently the most important variable for stocks. Rising long-term rates depress valuations—especially in AI and technology—and increase financing costs worldwide. For today’s trading, the US 10-year yield is at least as important to watch as Nasdaq futures.

2. Riksbank holds rates but sees future increases

Sweden’s central bank left its policy rate unchanged at 1.75% yesterday, but raised its projected path substantially and now expects hikes to begin this year. Stronger Swedish growth, a weaker krona and continued pressure from energy and the Middle East were factors. The bank lifted its 2026 GDP-growth forecast from 2.2% to 2.8%. Source: Riksbank

Why it matters: This marks a change for Swedish investments. Banks may benefit relatively, while highly indebted property companies and other rate-sensitive shares face a less favourable outlook. The Swedish krona also becomes particularly interesting to follow.

3. Trump–Xi brings a truce but no major breakthrough

Yesterday’s summit between Donald Trump and Xi Jinping ended without a major agreement on the hardest questions of trade, AI, critical minerals and Taiwan. The main concrete market effect was a two-month extension of the existing trade arrangement, delaying the risk of an immediate new tariff escalation. Source: Reuters

Why it matters: Avoiding an escalation helps semiconductors, European industrial companies and firms exposed to China in the near term. But the summit resolved few structural conflicts, so US–China tensions remain a significant market risk.

4. US limits UK safety testers’ access to new AI models

According to Politico, as reported by Reuters, the White House asked OpenAI and Anthropic to withhold new models from British AI-safety testers until US authorities had conducted their own reviews. It is a concrete sign that advanced models are increasingly treated as strategic technology rather than ordinary software. Source: Reuters

Why it matters: AI regulation is acquiring the geopolitical characteristics of semiconductor policy. This could affect how quickly models launch internationally and which countries and businesses get early access—relevant to AI investments and companies building on frontier models.

5. Google sends AI chips into space

Google plans to launch a prototype satellite next week under Project Suncatcher to test its AI chips in space for the first time. The long-term question is whether solar-powered satellites could perform AI computing and bypass some constraints on power and land faced by data centres. Source: Reuters

Why it matters: It sounds futuristic, but addresses perhaps the most physical constraint on the AI boom: energy. If it works, AI infrastructure could become a market not only for chips and data centres but also for power generation, satellites and space infrastructure.
