Amazon is planning to sharply cut the number of packages it ships through the U.S. Postal Service, a move that could cost the agency billions of dollars of much-needed revenue, the WSJ’s Esther Fung writes.

Long the Postal Service’s biggest customer, Amazon has already begun ratcheting down its postal volume and wants to reduce it by at least two-thirds by this fall, when its current contract with the agency expires, according to people familiar with the matter. 

USPS delivered more than a billion packages for Amazon last year, close to 15% of all the packages it delivered in the U.S. Amazon disclosed the plan to the Postal Service in a confidential bidding process for its last-mile delivery service. USPS solicited bids for the service for the first time, aiming to help it determine the true market value of the last-mile service.

Results of the last-mile bidding competition will be released in the second quarter, and contracts will be finalized by the end of the third quarter. That left Amazon concerned that it would have little time to make changes to its network if its bid weren’t accepted, the people said.

Amazon delivered 6.7 billion packages last year, while USPS delivered 6.6 billion, according to ShipMatrix. It was the first year Amazon’s parcel volumes exceeded the Postal Service’s volumes.

Ship movement across the Strait of Hormuz remains very limited, with only three tankers and a handful of general cargo vessels crossing since the weekend, the Journal’s Costas Paris writes.

Marine tracking and intelligence firms Windward and Kpler said the seven-day average ship crossings were around two a day, compared with more than 100 transits in peacetime. The few tankers leaving the Persian Gulf through Hormuz are mostly China-bound, though the oil volumes flowing out are substantially lower than normal. 

Despite the tension, Kpler estimates that 12 million barrels of crude have moved to China since the end of February—mostly from Iran, but also from other countries in the region. Some 1,100 ships are currently trapped in the Persian Gulf, according to ship brokers Clarksons and Braemar.

A Michigan battery factory once meant for General Motors’ electric vehicles has a new partner: Tesla.

South Korea's LG Energy Solution said it would produce battery cells for Tesla’s energy-storage business at a new factory in Lansing, Mich. Those cells will eventually power utilities and AI data centers, the WSJ’s Christopher Otts writes.

LG once planned to make batteries for GM’s EVs at the factory, but as the automaker pulled back on its electric ambitions, it sold its stake in the venture to LG last year. The new $4.3 billion LG-Tesla tie-up was part of a Trump administration announcement on Tuesday, among dozens of other deals, as part of its “energy dominance agenda.”
