Bitcoin extended its decline on Oct. 8, briefly approaching $82,200 — its weakest level since Sept. 21 — with the asset trading near $82,400 at the time of publication. BTC has fallen from the $86,000–$87,000 region as spot ETF redemptions and macroeconomic pressure weighed on crypto markets.

The pullback coincided with another surge in crude oil prices and elevated U.S. Treasury yields. Together, those developments have reinforced inflation concerns while tightening financial conditions for risk assets such as cryptocurrencies.

Bitcoin ETF Outflows Accelerate

Bitcoin's retreat came as American investors began selling their ETF holdings. Spot Bitcoin ETFs recorded more than $487 million in outflows on Thursday, erasing all of the gains made since the start of the month.

In total, spot Bitcoin ETF outflows have climbed to $165 million this month, a sharp reversal from the trend of the previous three months. The funds added $2.65 billion last month, after attracting $3.5 billion in August. Because these vehicles report their flows each trading day, the figures are widely tracked as a gauge of institutional demand for Bitcoin, and the coming daily reports will show whether Thursday's redemption pace persisted.

The funds now hold $107 billion in combined assets, with BlackRock's iShares Bitcoin Trust (IBIT) commanding the largest market share at more than $67 billion in assets under management. The outflows indicate that investors are starting to book profits after the recent rally that carried Bitcoin from $57,800 in July to $82,465.

Crude Oil and US Bond Yields Surge

Bitcoin is also retreating as crude oil prices rebound. Brent, the global benchmark, jumped to $105, while West Texas Intermediate (WTI) rose to $92.

Oil is climbing amid the ongoing US–Iran crisis, as Iran has intensified its attacks on ships in the region. On Thursday, the Islamic Revolutionary Guard Corps (IRGC) attacked a tanker the coast of Qatar, and there are reports that it has struck another vessel near Fujairah in the United Arab Emirates.

The attacks have triggered a sharp decline in the volume of crude passing through the Strait of Hormuz, a critical transit chokepoint for global oil shipments that has long carried roughly a fifth of the world's oil, after flows surged in September. According to Kpler, average flows jumped to as much as 15 million barrels per day in late September, but have now fallen to about 4 million barrels. Updates from shipping-analytics providers such as Kpler will offer the clearest near-term read on whether traffic through the chokepoint stabilizes.

There are also concerns that the United States could launch attacks against Iran even before the midterm elections. According to The Atlantic, Trump and some of his officials believe such strikes would help to bring oil prices down.

Bitcoin often drops when oil prices are in a strong upward trend, because elevated energy costs signal that inflation will continue climbing. Indeed, recent data show that gasoline and diesel prices have continued rising this month.

Rising oil prices have also driven a surge in U.S. bond yields. Data show that the ten-year yield rose to 5.327%, while the 30-year yield jumped to 5.7% — a level approaching the important resistance point of 6%. In most cases, Bitcoin tends to underperform the market in such an environment because it pays no monthly reward, making yield-bearing government debt comparatively more attractive.

US bond yields continued rising after the Federal Reserve published hawkish minutes, which showed that most officials expect the central bank to hike rates. Attention now turns to upcoming inflation readings and further Fed communications, which will indicate whether that rate outlook firms up.

Bitcoin Technical Analysis: Double-Top Neckline Comes Into Play

The daily chart shows that Bitcoin has pulled back over the past few days, moving from $87,198 last week to the current $82,414. The current level is notable because it coincides with the highest swings recorded in May and September this year.

The price is also testing the neckline of a double-top pattern a formation that typically develops after two failed attempts to advance and is widely regarded as a bearish reversal signal in technical analysis. The Relative Strength Index (RSI) has moved down from the overbought reading of 86 in August to the current 49.

As a result, the price may continue falling in the near term, with sellers targeting the key support level of $74,840 — Bitcoin's lowest point on Sept. 16. How the price behaves around these reference levels, particularly on a daily closing basis, is commonly how chartists confirm or invalidate such a pattern.
