Historical backfill: prepared on October 4, 2026; observations stop at the article date, using the US close and same-day yield observations.
On August 21, the two-year Treasury yield rose from 4.19% to 4.24% and the ten-year from 4.69% to 4.74%. Both increased five basis points, leaving their spread at 50 basis points. Yields rose without steepening between these two maturities. That does not establish a parallel move across every segment of the curve or identify a common cause.
The ten-year real yield rose from 2.35% to 2.40%, matching the nominal increase. Their simple difference stayed at 2.34 percentage points: approximate inflation compensation containing risk and liquidity effects, rather than a pure forecast of inflation over the coming decade. The nominal move cannot be assigned wholly to higher inflation expectations when the real yield rose too.
Long-Treasury ETF TLT lost about 0.4%, SPY and QQQ each gained 0.4%, and gold ETF GLD rose 2.0%, without a uniform hawkish response. Five basis points is a small change that daily noise may overwhelm. The next regular FOMC meeting was September 15–16; August had no regular policy meeting.
