Weaker dollar and lower Treasury yields drove Bitcoin to its strongest weekly gain in over three years.
Bitcoin climbed 23.6% for the week ending 21 August 2026, marking its second-largest weekly advance since February 2021. The rally followed a decline in U.S. Treasury yields and a softer dollar, fueled by expanded bond buybacks.
The cryptocurrency’s performance outpaced most traditional assets, reflecting heightened risk appetite. The prior week’s gain was modest, and the last comparable rally occurred during Bitcoin’s 2021 bull run. Market participants attributed the move to shifting liquidity dynamics.
No immediate market reaction data was provided, but the surge underscored Bitcoin’s sensitivity to macroeconomic shifts.
