What macro decision moved the market?

TLDR

The move was driven mainly by the US Federal Reserves upcoming policy decision, with markets focused on a possible 25 bp rate cut and balance?sheet signals.

1. Rate?cut odds and balance?sheet hints lifted risk appetite per a MarketWatch preview.
2. Liquidity tone improved as analysts flagged QTs end and RRP depletion as a tailwind in a Delphi analysis.
3. Secondary driver: Bank of Japans rate decision and carry trade risks, with a hold seen as risk?on per a market wrap.

Deep Dive

1. Fed Cut and Guidance

Markets are keyed to a potential 25 bp cut and, critically, any hint about balance?sheet or asset?purchase policy that could amplify liquidity transmission. A preview noted the Feds biggest decision might be the balance sheet, not just rates, a setup that tends to favor risk assets including crypto if dovish signals emerge. See the MarketWatch preview. Bitcoins tone improved as cut bets stayed firm into the week, framing near?term crypto moves as a function of policy easing probabilities, per an early session update on Investing.com.

2. Liquidity and QT Shift

Analysts highlighted a structural liquidity turn: quantitative tightening ending, the Treasurys cash balance drawing down, and the reverse?repo well largely depleted. That mix creates a marginal tailwind for risk assets relative to earlier headwinds, according to Delphi Digitals macro read (summarized in a community post). The same thesis appeared in broader crypto coverage, framing 2026 as a gentler policy backdrop rather than a sudden pivot, consistent with a controlled descent in policy tightness.

3. BoJ and Carry Trade

The Bank of Japans stance matters through the yen carry trade. A steady policy stance tends to support global risk appetite, while a hawkish surprise can unwind carry and pressure risk assets. Commentary flagged the BoJ as a key monthly decision, with a hold seen as supportive for equities and crypto via risk appetite, per a December outlook on Yahoo Finance.

Conclusion

The dominant catalyst was the Federal Reserves impending decision, especially the combination of rate?cut odds and balance?sheet signaling, with liquidity dynamics turning less restrictive. A supportive BoJ outcome reinforces risk?on, while a hawkish twist from either central bank could quickly cap cryptos bounce and revive volatility.
