Bitcoin was trading at $85,736 on Tuesday, 22 September, defending the $85,500 level after a minor 0.97% correction cooled its advance above $85,000 for the first time in eight months. The move took the cryptocurrency to its highest level since January. The rally followed Brent crude’s decline from above $109 a barrel the previous week to below $100, while the 10-year Treasury yield eased to roughly 4.96% from 5.04%. Lower yields can reduce the opportunity cost of holding a non-yielding asset such as Bitcoin and support risk-on markets, helping lift the S&P 500 1.5% and the Nasdaq Composite 2.1% in the same session. Bitcoin traded between $81,724 and $87,330 before settling near $85,435, with a market capitalization of around $1.7 trillion. Reported spot Bitcoin ETF inflows and short covering may have added to the advance, although no verified figures accompanied those claims. The retreat in oil and yields represents relief from an inflation shock, not confirmation of a sustained downtrend. Oil and yields remain historically elevated, and the geopolitical signs of de-escalation around the Strait of Hormuz do not amount to a settlement. Traders will be watching whether both measures continue falling through the week or whether Monday’s move was temporary, including ahead of President Trump’s meeting with Xi on Thursday.
