Bitcoin Hits $81,000 as Oil Woes Drive US Bond Yields Higher

Bitcoin Hits $81,000 — Bitcoin surged past $81,000 on Friday, September 18, 2026, as rising US bond yields, fueled by global oil supply concerns, triggered a sharp rally in crypto markets.

Data from TradingView showed BTC/USD reaching local highs of $81,034 on Bitstamp, marking a 6% gain for the day. The move liquidated approximately $250 million in cumulative cross-crypto short positions over a four-hour period, according to CoinGlass.

The price action coincided with renewed uncertainty in energy markets. The International Energy Agency warned that constrained oil flows through the Strait of Hormuz, now at 7.6 million barrels per day, could force demand reductions. This pushed US 30-year bond yields up 90 basis points to 5.34%.

Analysts noted Bitcoin has reclaimed its True Market Mean cost basis of $76,660, putting it back into a “bullish regime.” However, trader Rekt Capital highlighted $82,000 as a key resistance level that must be broken to avoid a double rejection pattern similar to the one seen in mid-May.
