**December 9 – Deribit officials confirmed today’s largest Bitcoin (BTC) options block trade: a user bought a $90,000 put option with January-end expiry and sold a $90,000 put option with February-end expiry, with each leg involving 375 BTC.** **The trade signals the user’s bet: BTC will fall by late January, then rebound above $90,000 before February concludes. Per Deribit, current market optimism is largely exhausted; some traders are wagering on a downturn due to risks tied to the January Strategy (linked to potential index exclusion), but remain clearly bullish on a post-February market recovery.**

On December 9th, Russell Investments Chief Investment Strategist Paul Eitelman said in a report that the Federal Reserve’s rate decision this Wednesday is a tough call—with FOMC members split on how much "insurance" to offer the economy amid a rare mix of solid growth and weak job gains. Russell Investments expects the Fed to deliver a hawkish 25-basis-point rate cut, with its forward guidance on future rate moves likely to remain cautious. "We anticipate the Fed will slow or pause its easing cycle in early 2026, with a terminal rate of 3.25% to 3.5%," Eitelman noted. He also pointed out that the current 10-year Treasury yield stands at 4.1%, above Russell Investments’ fair value estimate—supporting a strategic allocation to duration risk in portfolios.
