Bitcoin slips below $80,000 as Federal Reserve meeting begins

Bitcoin fell 0.4% to about $79,700 after midnight UTC on Tuesday, slipping back under $80,000. Ether lost 0.5% and CoinDesk’s DeFi index dropped 1.8%, the steepest decline among its indexes. Crypto did not follow a 3.1% rally in South Korea’s Kospi, even as U.S. crude approached $102 a barrel. The break stands out because it arrived as the Federal Reserve opened a two-day meeting and traders reduced risk into the rate decision.

Bitcoin has probed $80,000 several times since last week’s high near $84,777. U.S. spot bitcoin ETFs took in $110 million on Monday after $774 million of withdrawals over the prior two sessions, leaving October still negative by about $202 million. Strategy bought no bitcoin last week and spent $204.9 million on STRC preferred-share buybacks, holding 848,517 BTC. The Crypto Fear & Greed Index slipped to 48, still in neutral territory.

Futures open interest rose as prices fell and funding stayed positive, so leveraged longs have not fully exited. The most traded bitcoin option was the $72,000 put expiring Dec. 25, and 25-delta skews remained positive, showing demand for downside protection. Retail deposits of bitcoin to Binance nearly doubled over 30 days to $10.8 billion, while large-holder deposits fell. The open question is whether $80,000 holds through Wednesday’s decision or whether ETF and retail selling force a deeper break.

Fed prices a hold on Wednesday with an 80% chance of a December hike

The Fed began its Oct. 27–28 meeting with the funds rate at 3.75%–4.00% after a September increase. CME FedWatch showed about a 90% chance of no change on Wednesday and roughly an 80% chance of another hike in December. Chair Kevin Warsh’s press conference is the main event for rates markets. The Bank of Canada also decides Wednesday, the ECB on Thursday and the Bank of Japan on Friday.

September CPI surprised to the upside, with a broader core print than the prior month. Core PCE, previously 3.0% year-on-year, is due Thursday—the day after the FOMC—alongside the Q3 GDP advance estimate, expected at 3.2% annualized. Oil above $100 has kept transport and goods inflation from cooling as cleanly as earlier in the year. That mix leaves the committee with hot energy prices and incomplete inflation data at the moment of the vote.

A hold is widely priced, but the December path is not. Higher crude feeds the inflation channel even if the committee stays put this week. Because PCE arrives after the statement, markets will parse Warsh’s language without the latest official print. The tension is a pause that markets treat as temporary while still assigning high odds to a year-end hike.

Oil stays above $100 as Tehran talks collide with U.S. strike reports

Crude eased after reports that Saudi, Turkish and Pakistani officials travelled to Tehran, but prices remained elevated. Brent traded near $115–$116 a barrel and WTI near $101–$102, down from more than $117 and $103 at the end of last week. CoinDesk recorded U.S. crude approaching $102 as bitcoin slipped. Profit-taking met a still-intact war premium.

Houthi attacks on Saudi energy infrastructure continued, and Iranian strikes on tankers in the Strait of Hormuz have been frequent this month, with at least 28 vessels reported attacked in October. The IEA has said the supply disruption will extend into next year. India’s crude basket hit $123.29 last week. Those physical constraints, not only headlines, are what keep the floor under prices.

CNN reported that U.S. forces could strike Iran within 96 hours of an order from President Trump, offsetting the diplomatic visit. Oil futures funding stayed negative, pointing to a persistent short bias even as open interest rose. The market is pricing de-escalation hopes and a strike option at the same time. Whether Brent holds above $110 into the Fed decision is the near-term test for inflation expectations.
