Expect governments to pay close attention. “Financial regulators in the United States and other countries could stop Libra before it is even released,” Mr. Isaac and Mr. Popper write, given their worries about its potential use in crime or its ability to amplify Facebook’s power. Politico has more on what that could look like.

Companies don’t want more tariffs. Tough.

Businesses, from toymakers to port officials, testify this week in seven days of hearings about the Trump administration’s plan to impose tariffs on $300 billion worth of Chinese imports. Those companies think their efforts will be largely futile, Ana Swanson of the NYT writes.

• Toymakers are worried, because 85 percent of all toys sold in the U.S. are now made in China, and the tariffs would hit just as they’re stocking up on holiday-season products. (One lobbyist, Rebecca Mond, clutching a Pikachu doll, said, “This guy is not a security threat.”)

• Mark Corrado, the president of a women’s underwear maker, testified that America no longer has enough people who can sew to make brassieres as well as they’re made in China.

• John Reinhart, the head of the Virginia Port Authority, warned that the proposed new tariffs could raise prices for the cranes that unload ships: “The cost of imposing tariffs on gantry cranes poses a significant risk to continued economic growth for the communities of Virginia and beyond.”

Several companies testified at previous tariffs hearings only to see the levies imposed anyway.

Prospects of dodging tariffs this time look shaky. President Trump is set to meet with President Xi Jinping of China at the Group of 20 gathering later this month. But White House officials say that they are unlikely to strike a deal then, and it remains unclear what would persuade Mr. Trump to back off.
