Bitcoin climbed to $86,734 on Tuesday, September 22, its highest level since late January, after breaking resistance near $82,000 the previous day. Analysts attributed the advance to easing macro pressure, lower Treasury yields, falling oil prices, renewed institutional demand and $433 million in spot Bitcoin ETF inflows recorded Friday. The rally also accelerated as traders covered short positions. Paul Howard of Wincent said Bitcoin could face near-term resistance between $88,000 and $90,000, while Jeff Anderson of STS Digital said $90,000 and the year-to-date high of $97,500 were in view. Market observers are watching for regulatory guidance from the SEC (U.S. securities regulator) and CFTC (U.S. derivatives regulator) after the Clarity Act failed a crucial Senate vote the previous week.
