Aircraft-Part Licensing Slowed for China

Commerce is reportedly delaying aircraft-parts licensing for China, using access to U.S. aviation supplies as leverage in trade negotiations. Slower approvals and limits on quantities licensed raise delivery risks in a market that bought $15.9 billion in U.S. civilian aircraft, engines, equipment and parts in 2025.

Diesel Export Ban Could Backfire; White House Denies Preparing Embargo

The White House’s denial that it is preparing a diesel export ban leaves the proposal a political demand rather than an announced policy. An embargo could briefly lower prices near Gulf Coast refineries but offer limited relief at the pump: reduced refinery output could raise gasoline and jet-fuel costs, while import-dependent West Coast markets face higher international prices.

Treasury’s first outbound-investment penalty exceeds value of underlying investment

The case shows that even a small investment through an overseas subsidiary can expose a U.S. parent to substantial penalties.

Treasury Withdraws Crypto Mixing and Self-Hosted Wallet Proposals, Citing Privacy and Reporting Concerns

The withdrawals reflect Treasury’s broader shift toward easing digital asset regulation, giving greater weight to financial privacy and compliance costs despite documented use of mixers in illicit finance. Alongside the department’s removal of Tornado Cash sanctions, the move signals a retreat from some preventive measures aimed at cryptocurrency abuse.

G7 Reserve Deal Defuses U.S. Diesel Export Threat

President Donald Trump stepped back from threatening a U.S. diesel export ban Friday after the Group of Seven agreed to release 100 million barrels of crude oil and fuel from emergency reserves. The agreement reduces the immediate risk of a supply disruption for Europe and Mexico, while shifting attention to whether reserve releases can bring sustained relief to American consumers.
