The U.S. Treasury 10-year bond yield just closed its third consecutive declining session, according to data from the U.S. Treasury Department (compiled via FRED). This is not an isolated drop worth noting, but rather an extended downward trend spanning three straight periods, bringing the 10-year yield to 4.63% as of August 13, 2026, down 0.05 percentage points from the previous session (4.68%). For millions of Vietnamese Americans with floating-rate mortgages tied to long-term bond yields, or those considering refinancing, this continuous downward trend matters more than any single data point.
10-year U.S. Treasury bond yield
Looking at a broader timeframe, the current 4.63% level is actually the lowest point across the entire recent tracking period, 0.05 percentage points below the 4.68% average for this period. However, compared to a year ago when the yield stood at 4.24% (August 13, 2025), the current 4.63% is still 0.39 percentage points higher. In other words, the three-session decline is merely a correction within a trend where yields remain higher than a year prior. Examined across a longer data spectrum spanning 259 periods from August 1, 2025, the current 4.63% still sits at the 93rd percentile, meaning it is higher than most yield levels recorded during this period, which has ranged from 3.97% to 4.75%.

Notably, the 10-year Treasury bond yield does not move in sync with the Federal Reserve's policy rate. According to the Federal Reserve (FRED), the federal funds rate currently stands at 3.63% as of July 1, 2026, down 16.17% from a year ago, a much sharper decline than the movement in the 10-year yield. Meanwhile, the 30-year fixed mortgage rate, according to Freddie Mac, stands at 6.67% as of August 13, 2026, even rising slightly 1.37% compared to a year ago. For a specific home purchase loan, this means that although the Fed's policy rate has declined significantly, Vietnamese American homebuyers in the United States are still paying mortgage interest rates that are nearly unchanged, or even slightly higher than a year ago. The dataset does not specify the exact reason for this gap, so we can only note: the two interest rate lines are moving in different directions.
For those considering buying a home or refinancing in the coming weeks, the figure to watch is not how much the Fed rate has fallen, but rather the 6.67% rate that Freddie Mac just announced for 30-year loans, as that is the number that determines actual monthly mortgage payments.
The 10-year Treasury bond yield fell for three consecutive sessions, down to 4.63%, but still remains 0.39 percentage points higher than one year ago.
