Bitcoin Breaks Above $86,500 as Nasdaq Hits Records and Oil Slides on Iran Signals

Bitcoin clears resistance as crypto market tops $3 trillion

Bitcoin traded near $86,559 on Tuesday, up 12.2% over the past week, after pushing through the resistance band between $79,673 and $84,144 that had capped its rally through most of September. The move lifted total crypto market capitalization above $3 trillion. The Crypto Fear & Greed Index stood at 79, deep in "greed" territory, while the Altcoin Season Index sat at 49, indicating Bitcoin still leads even as altcoins begin to move.

Key numbers behind the move

• Bitcoin: ~$86,559, up 12.2% over seven days
• Total crypto market cap: above $3 trillion
• Crypto Fear & Greed Index: 79 (Greed)
• Altcoin Season Index: 49
• Of the top 100 coins, 97 posted gains over the past week

Wall Street rallies alongside crypto

The breakout coincided with a broad risk-on mood on Wall Street. The Nasdaq Composite closed at a record on Monday, up 2.26% for its best day since June, driven by AI-linked chipmakers. Intel jumped 12%, and AMD gained roughly 10%, crossing a $1 trillion market cap. Chipmakers extended their rally into Tuesday, marking their longest winning streak since April. On Tuesday, the Nasdaq was up about 0.4%, touching a fresh intraday high, while the S&P 500 barely moved.

Oil falls as Iran signals possible reopening of Hormuz

Oil did the heavy lifting in markets on Tuesday. Brent crude briefly slipped below $98 a barrel and WTI fell under $93, their lowest levels since September 8, after reports that Iran offered to reopen the Strait of Hormuz within days if Washington eases pressure. President Donald Trump told the U.N. General Assembly he expects a deal with Iran "right after the election," referring to the November midterms. Saudi Arabia was also working to restart its East-West pipeline by the weekend.

The Federal Reserve's unusual policy mix

The Federal Reserve raised its benchmark rate by 25 basis points to 3.75%-4% on September 16, its first hike since 2023, approved unanimously 12-0. Hot inflation data forced the move: the Producer Price Index accelerated to 5.4% annually in August, with gasoline driving roughly a third of that month's CPI gain. However, even while hiking, the Fed has not stopped injecting money into the system. It resumed regular purchases of short-term Treasury bills in December 2025 to keep bank reserves "ample." These purchases absorb Treasury supply and channel cash toward buyers of risk assets, partially offsetting the tightening effect of higher rates. The Fed's bond holdings sit near $6.7 trillion, well below the $9 trillion peak of 2022 but no longer shrinking.

What the Bitcoin chart shows

Bitcoin's daily chart supports the rally. Price cleared the $79,673-$84,144 zone and is now testing a trajectory toward $90,000. The cryptocurrency has also entered a "golden cross," a pattern traders widely recognize as bullish, which forms when the 50-day average price crosses above the 200-day average price. Using Fibonacci extensions, the next resistance targets if bulls hold control are $90,763 and $95,074. If the $79,673 zone fails on a pullback, the next support levels sit at $75,436 and then $73,617.

Prediction markets and altcoin activity

On Myriad, a prediction market developed by Decrypt's parent company Dastan, traders priced in a 48% probability that Bitcoin reaches $90,000 this month, against a 25% probability it heads to $92,500. Altcoins also caught a bid: XRP climbed to $1.57, Solana gained 18.2% over the week, and Zcash extended its multi-month rally to $1,551, up 36.7% over seven days.

What is still unclear

Whether September's rate hike is a one-off response to an oil-driven inflation spike or the first of several planned increases this year remains uncertain. The Fed's next policy meeting lands October 27-28, when markets will look for clarity. The median 2026 projection from the Fed puts the federal funds rate at 4.1% by year-end. It is also unclear whether Bitcoin can sustain its position above the $86,500 level or whether it will face pullback pressure at the Fibonacci resistance zones ahead.

Why this matters

The simultaneous strength in Bitcoin, tech stocks, and the broad risk-on mood in markets reflects a combination of factors: favorable technical patterns, continued liquidity from Fed balance sheet purchases despite higher rates, and falling oil prices easing inflation concerns. The fact that 97 of the top 100 coins are green over the week suggests broad-based strength across crypto, not just a Bitcoin-only move.

What happens next

Traders will watch the Fed's October 27-28 policy meeting for signals on whether September's hike was a one-time event or the start of a series. Bitcoin's ability to hold above the $84,144 former resistance zone and push toward the $90,763 Fibonacci target will be closely monitored. Oil prices and any progress on the Iran nuclear deal will also remain key market drivers.
