Bitcoin climbed back above $91,000 in Asian morning trading on January 4, 2026, reaching its highest level in nearly three weeks. The move did not come with the usual signs of speculative overheating. Data cited in the source points to a quieter structure: restrained futures pricing, lower open interest, and price momentum led largely by spot demand.
Futures basis near 4% points to a restrained derivatives market
According to the source material, Bitcoin pulled back on January 3 after news of a U.S. military strike on Venezuela, then recovered the decline within roughly 20 hours. Even with that rebound, derivatives activity stayed contained. CryptoQuant data showed annualized futures basis across major exchanges at only about 4%, well below the levels seen at the October 2025 peak, when it often ran above 15%.
Open interest was also reported to be down by nearly $40 billion from its earlier high. That matters. After the heavy deleveraging at the end of 2025, the market appears to be carrying far less speculative leverage, yet Bitcoin still pushed to a short-term high. The price advance, in that setup, looks more tied to outright spot buying than to leveraged chasing in futures.
Spot Bitcoin ETF flows reversed quickly after year-end selling
In the last two weeks of December, U.S. spot Bitcoin ETFs recorded $1.29 billion in net outflows, a move that raised questions about whether institutional buyers were stepping back. The source describes that selling as more consistent with technical year-end activity, including tax-loss harvesting and balance-sheet adjustments, rather than a broad bearish shift in positioning.
After the calendar turned, the flow picture changed fast. On January 2 alone, net inflows reached $470 million, with BlackRock accounting for the largest share. Within two days, flows had returned to levels seen before Christmas, suggesting that the longer-term institutional allocation case had not materially changed.
Options markets stayed calm with activity clustered near current prices
Signals from options were similarly subdued. The source said Bitcoin’s 30-day put-to-call ratio stood at 0.48, below the 0.5 threshold, indicating stronger demand for calls than puts. Professional traders were not aggressively adding downside protection, a sign that concern over an immediate retest remained limited.
Implied volatility held around 45%, far below the triple-digit readings seen during the more extreme conditions of October 2025. Trading activity was concentrated around strikes between $88,000 and $91,000, showing positioning near the current range rather than a scramble for protection or a rush into high-volatility bets.
Taken together, the source presents a market where Bitcoin at $91,000 is not being driven by excessive leverage or panic hedging. Low futures basis, renewed ETF inflows, and muted options insurance demand all point to a rebound shaped mainly by spot capital after a broad cleanup in positioning.
