What changed

Watch next
Sunday’s Atlético Madrid derby will show whether Madrid can convert early chances and maintain control without requiring another late attacking overload.[9]

Why now
Warnings from AI executives and researchers intensified as the House approached a recess lasting until after the early-November midterm elections.[1][4][6]

The U.S. 10-year Treasury yield breached 5% on Sept.

Cheatsheet for Why does a 5% Treasury yield matter beyond the bond market?. Text equivalent is attached.

Watch next
Watch the Fed’s Sept. 16 rate decision and dot plot, plus demand at the Treasury’s US$13 billion 20-year bond sale and US$19 billion 10-year inflation-protected securities sale.[3]

Cheatsheet for How the EPA rollback dismantles power-sector climate controls. Text equivalent is attached.

Why it matters: Power plants are the second-largest source of U.S. climate pollution, so the action follows the administration's repeal of rules covering vehicles, the largest source. If the rollback survives expect…
