The 30-year Treasury yield touched 5.323 percent on 18 August 2026, its highest since 2007, as Bloomberg and Yahoo Finance reported, with the 10-year near 4.7 percent against roughly 4.2 at the start of the year per CNN. This is a global move: Japanese 10-year debt at a three-decade high, German 30-year bonds costliest since 2011, French 30-year borrowing at pre-2008 levels. The framing most coverage reached for was that Japan was dumping Treasuries. It is the opposite of what happened. The US and Japan ran their first joint yen-buying intervention since 1998, roughly 85 billion dollars over two days per OMFIF, and Tokyo financed it through the Federal Reserve FIMA repo facility specifically to avoid selling Treasuries, with the New York Fed selling euros rather than dollar assets. On 19 August the Treasury said it would at least double buybacks of 10, 20 and 30-year bonds, from two billion to four billion dollars per operation. Those operations do not begin until 9 September. Nothing has been bought back yet, and the relief lasted about a day. In the same week, Freddie Mac survey put the 30-year fixed mortgage at 6.65 percent, down from 6.67 and falling for a second consecutive week.
