Bitcoin’s slide below $100,000 is a price threshold, not a single-cause explanation. CoinDesk reported that on October 1, 2026, Bitcoin was just above $83,700 after briefly moving above $85,500; that rebound faded while U.S. Treasury yields remained near recent highs. Separate reporting on the wider 2026 downturn points to overlapping pressures, including interest-rate expectations, geopolitical uncertainty, earlier spot Bitcoin ETF outflows and corporate selling. None of those factors, alone or together, establishes a definitive cause or guarantees a bottom.
What happened when Bitcoin fell below $100,000?
The $100,000 mark is a round-number threshold that can attract attention, but crossing it does not identify why the price moved. CoinDesk’s October 1, 2026 report put Bitcoin just above $83,700 after a Wednesday rally briefly lifted it above $85,500. The recovery lost ground as Treasury yields stayed elevated. These are dated market snapshots, not current quotes.
In that same report, CoinDesk cited a 10-year Treasury yield around 5.28% and a 30-year yield around 5.62%. The outlet’s account linked persistent yields and dollar strength with pressure on assets that do not pay interest. That is a market explanation of the session, not a rule that predicts Bitcoin’s next move.
Why did the rebound fade?
Inflation expectations and interest rates
CoinDesk reported that softer-than-expected inflation initially helped risk assets, including Bitcoin. But the optimism did not persist while Treasury yields remained elevated. Investors weigh expected returns across asset classes; higher yields can make interest-bearing investments more attractive by comparison. That mechanism helps explain why a favorable inflation signal did not necessarily translate into a lasting Bitcoin rally. It does not establish that yields caused every part of the decline.

Risk appetite and uncertainty
For the broader downturn, IG’s June 2026 retrospective described changing rate expectations alongside geopolitical uncertainty. Those are wider-period explanations, distinct from CoinDesk’s account of the October 1 session. Uncertainty can make investors less willing to hold volatile assets, but the reviewed reporting does not quantify how much any one factor contributed.
What other pressures have been associated with the wider 2026 decline?
ETF flows and corporate selling
IG cited a period of substantial spot Bitcoin ETF outflows and corporate selling during the earlier decline. Those claims describe that reporting period, not necessarily October conditions. Flows change: BetaShares reported renewed ETF inflows in a September 2026 note. Without a dated, current flow figure, earlier outflows should not be treated as an ongoing explanation for the October move.

Leveraged liquidations
A Bitcoin.com market report associated a price decline with liquidations of leveraged positions. When a leveraged trade moves against a trader, an exchange or lender may close it, adding forced buying or selling to market activity. The report’s association is not proof that liquidations caused the wider downturn; leverage is better understood here as a possible amplifier of short-term moves.
Mining economics
The Block reported a Bitcoin mining difficulty reduction in June 2026 and attributed it to pressure on miners’ margins. This is context for how market conditions can affect mining economics, not evidence that mining caused the broader selloff.

The reviewed coverage does not provide a statistical breakdown that assigns a share of the October move to yields, ETF flows, selling, or any other factor. The figures above therefore describe reported market conditions; they do not prove a causal percentage.

Dan Khus, chief analyst at LVRG Research, told CoinDesk: “A sustained drop in that yield is the move that would give the next rally room to hold.” That is Khus’s market view, not a forecast or a guaranteed condition for a recovery. A lower yield would not by itself establish that Bitcoin had found a durable floor.
Rank #4
More broadly, any judgment about whether selling pressure is easing depends on fresh price, yield and flow data. The cited October prices and yields are snapshots, while the cited ETF-flow coverage spans different periods. None of the explanations establishes a dependable bottom or promises a rebound.
