Bitcoin Holds Near $81,500 as Iran Tensions Weigh on Markets
Bitcoin fell about 3% on Thursday, trading near $81,500 as renewed US-Iran tensions and weaker US stocks pressured risk assets. President Donald Trump said the US was “not negotiating” with Iran and suggested events could unfold soon. The S&P 500 fell 1.3% and the Nasdaq dropped 2.3% at the time of reporting.
Bitcoin hovered around the estimated cost basis of US spot Bitcoin ETFs. Bitfinex Alpha analysts expected BTC to remain in a range of $81,300 to $84,400 ahead of the Federal Reserve’s Oct. 28 meeting. A sustained move above $84,400, supported by ETF demand and stable leverage, could signal a breakout. A close below $81,300 could put Bitcoin at risk of testing the Oct. 15 low of $79,821.
The immediate outlook is sensitive to geopolitical headlines, US equities and interest-rate expectations. Traders are watching the ETF cost basis and the stated price levels for signs of whether Bitcoin will stabilize or extend its decline.
Bearish
The immediate market signal is bearish. Bitcoin fell roughly 3% as renewed US-Iran tensions coincided with declines in US equities, indicating weaker appetite for risk. Bitcoin’s position near the estimated $81,500 cost basis of US spot ETFs makes that level a closely watched reference, but it is not a guaranteed floor.
In the short term, traders may respond to geopolitical headlines with reduced exposure, tighter stop-losses or increased hedging. Bitfinex Alpha identified $81,300 as a key downside threshold; a daily close below it could increase the chance of a test of $79,821. Conversely, sustained ETF demand and stable leverage could help Bitcoin break above $84,400 and challenge the near-term bearish tone. The Oct. 28 Federal Reserve meeting adds another potential source of volatility through changing rate expectations.
Similar episodes of geopolitical stress have often prompted broad risk-off moves, with crypto trading alongside technology stocks rather than acting as a safe haven. However, the impact can fade if tensions ease or investors return to risk assets. Over the longer term, this article alone does not establish a lasting trend: ETF flows, macroeconomic conditions, Fed policy and the resolution or escalation of tensions will be more important. The bearish classification reflects the immediate pressure, not a prediction of sustained declines.
