Bitcoin Reaches Two-Year Quarterly High with 43.1% Q3 Gain

Bitcoin has seen its best quarterly performance in over two years, with a gain of 43.1% so far in Q3 2026.

This surge coincided with the US Treasury's announcement to increase buybacks of long-dated Treasuries on August 19.

Since then, Bitcoin has risen by 29.8%, with US spot Bitcoin ETFs posting $2.4 billion in inflows for the week ending September 25 - their largest weekly intake since October 2025.

This marks a sharp reversal from July's total outflows of $5.0 billion, with year-to-date inflows now standing at $1.0 billion.
