White House Insider Trading Again? Day Before US Treasury's Surprise Move, Long-Duration Treasury ETF Sees 'Largest Single-Day Net Inflow in History'

The day before the US Treasury announced a major expansion of its long-duration bond buyback program, a highly sensitive long-duration Treasury ETF recorded a record single-day net inflow of $123 million, with trading volume nearly doubling. Following the announcement, the 30-year Treasury yield fell as much as 10 basis points in a single day, and the ETF surged 3.2%. The unusual timing of the capital inflows has once again raised market suspicions of insider trading, echoing the earlier "White House insider trading" controversy.
