Easy does it. Federal Reserve Governor Christopher Waller said he'd back a quarter-point rate cut at September's meeting and more easing over the next three to six months. Further clues on the rate path are expected in today's inflation data, which may show the central bank's preferred gauge of price pressures rose in July at the fastest pace in five months. A dissenter at the last meeting, Waller has pressed for looser policy to support jobs—and is seen as a potential candidate to succeed Jerome Powell as Fed chair.

The Trump administration's campaign against Fed Governor Lisa Cook intensified after FHFA Director Bill Pulte filed a new criminal referral alleging mortgage fraud. She'll seek an emergency hearing this morning to block her removal. Cook has signaled an unintentional "clerical error" may have been behind the dispute. Read more on the potential fallout from Trump's unprecedented attacks on the Fed in our Big Take below. Unhealthy obsession. The administration is tapping a deputy of Health Secretary Robert F. Kennedy Jr. to lead the Centers for Disease Control after firing its recently-confirmed chief in a clash over vaccine policy. Jim O'Neill will serve as acting director, though it's unclear how closely he'll align with Kennedy's push to remake immunization policy. Earlier this year, he called vaccines "one of the greatest public health interventions in human history." One thing's clear: out-of-pocket costs for Covid shots aren't getting any smaller.

Super Micro Computer flagged concerns about its financial controls.

Chinese President Xi Jinping's closest allies may find little reassurance at the Shanghai Cooperation Organization summit, which kicks off Sunday. He's expected to focus on the bloc's future as Donald Trump tries to hem in Beijing's ambitions and generally upends US relationships. Meanwhile, Brazil isn't taking Trump's trade war lying down as President Luiz Inacio Lula da Silva prepares retaliation. Japan is taking the opposite tack; its top trade negotiator plans at least one more US visit before tariffs are finalized.

Deep Dive: Feeling the Heat

A participant during a heat stress trial inside a climate chamber at the University of Sydney. Photographer: Mridula Amin/Bloomberg Scientist Glen Kenny spent three days in a chamber heated to 104F (40C) to study heat stress—research that's reshaping how governments and companies respond to a hotter world. The 61-year-old tested his own body against the kind of brutal indoor temperatures seen during a 2021 Canadian heat wave that killed hundreds. He felt fine the first day, but on the second his internal temperature approached dangerous levels. By day three, he'd shed about 10 pounds. The findings are helping rewrite public health standards and guide firms from Adidas to United Airlines in protecting workers and reducing losses. While the true toll remains elusive, extreme heat in Europe has become a killer, despite new laws. Read our explainer on how rising temperatures are testing the human body's limits.
