European Central Bankers Fear Turbulence Amid US Treasury Interventions

Europe's central bankers left the annual Jackson Hole Economic Symposium with growing concerns about their relationship with Washington. Sources familiar with the discussion revealed that Federal Reserve policymakers had to reassure their European counterparts that they would honor all commitments, despite being separated from the administration.

The recent US Treasury interventions in the Japanese yen and long-term US borrowing costs have raised eyebrows among European officials. They felt left out of the loop when the US did not give them a customary heads-up about selling euros for the Japanese currency.

US Treasury Secretary Scott Bessent explained that the transaction was 'just a reallocation of resources,' but European officials were infuriated by the lack of communication. Some saw it as a message from the US that they would do whatever they want, while others attributed it to an honest oversight due to the unusual nature of the transaction.

The sources also expressed concerns about Bessent's plan to increase buybacks of longer-dated bonds, which may need to be financed by issuing more shorter-term maturities. This move was seen as a sign that the administration is willing to take unusual measures to cap borrowing costs, potentially leading to market upheaval beyond the US.
