Bitcoin traded below $79K as U.S.-Iran tensions and a rise in Treasury yields pressured prices

Bitcoin was reported trading below $79K, with one report citing a move to about $78,299 amid heightened U.S.-Iran geopolitical tensions and a rise in U.S. 10-year Treasury yields to a three-year peak this week ^[1].

Another report also tied the BTC dip under $79K to the same set of factors—U.S.-Iran tensions and Treasury yield strength—though it did not provide additional quantified market details in the provided excerpt ^[2].

CryptoPotato reported that the U.S. Treasury Department had earlier announced it would double liquidity-support buybacks for longer-dated government debt, producing an immediate BTC lift at the time, but that a subsequent Treasury change—tripping it to $6 billion—was followed by BTC staying flat and even dipping instead ^[3].

Separately, Coindoo said BTC faces two weekly technical barriers, citing a 50-week SMA near $79,600 and a main breakout zone around $82,000–$82,800, while also reporting that ETF flows turned negative on September 8 ^[4].

For Ethereum, Blockonomi reported that ETH has remained confined within a narrow trading corridor around $2,486–$2,500 for more than three weeks and highlighted resistance at $2,525–$2,535 and downside levels at $2,478 and $2,435 ^[5].
