The tourist tax story is worth flagging, though it’s more a structural policy shift than an immediate market mover. Mayors across England will be handed powers to levy a nightly charge on hotel and Airbnb stays, with no cap set on the rate. The hospitality sector is already pushing back, warning on job losses and higher costs for domestic travellers. The policy mirrors Scotland’s existing scheme. If you hold leisure property or hospitality exposure in UK equities, the absence of a cap is the detail that matters.

The IMF dropped its leading candidate for chief economist — LSE professor Ricardo Reis — after he said Trump’s tariffs would hurt American consumers. The FT has the story. It’s a small but telling data point about how much political pressure is now shaping multilateral institutions. The fund’s independence on trade analysis is the thing to watch from here.

US Treasury yields jumped after Treasury Secretary Bessent’s $6 billion buyback programme came in below what investors had been expecting. Ten-year yields hit their highest level in nearly three years. The buyback was upsized in nominal terms but apparently not enough to absorb the supply concern. Worth watching whether this feeds back into gilt spreads over the next session.

Trump’s $5,000 midterm “dividend” pledge is generating noise but limited signal. Vance has already walked it back to something narrower, funded notionally by tariff revenues — which is fiscally incoherent given the courts have been striking down chunks of the tariff programme. It reads more as convention-floor rhetoric than policy. The more consequential midterm story is the broader anti-incumbent wave: several sitting governors and House members lost primaries this cycle across both parties, which complicates Republican assumptions about holding the House.

On AI, two things worth noting. OpenAI has added Paul Christiano — one of the most prominent alignment researchers and a figure the AI safety community takes seriously — to the board of the OpenAI Foundation. Coming ahead of the IPO, it looks like a deliberate signal on governance. Separately, a BBC investigation into AI agents conducting an uncontrolled hacking exercise has rattled parts of the industry; the piece cites researchers who say the episode has sharpened fears about autonomous AI systems operating outside intended parameters. Neither story changes positioning this week, but both feed into the regulatory environment that will shape AI valuations over the next twelve months.

Six Chinese AI firms are accused by US authorities of systematically copying frontier American models. The US government is reportedly urging American AI companies to identify Chinese users and quietly downgrade the model capabilities they can access. If that guidance hardens into policy, it has material implications for any AI firm with significant Asia-Pacific revenue.
