Bitcoin's price reaction to scheduled macroeconomic announcements follows a predictable playbook: sharp intraday spikes that fade fast, then a return to baseline.

Fed chair speeches at Jackson Hole conferences move Bitcoin two to three times its normal volatility within the first 30 minutes, according to market data spanning January 2018 to October 2026. Fed press conferences come second at 2.6x normal movement, followed by jobs reports at 2.2x and rate decision statements at 2.0x.

CPI reports generate 1.9x normal volatility in that critical first half-hour. Jackson Hole speeches also produced the highest daily volatility among all events studied—2.5 times an ordinary day—but this elevated activity typically subsides within one to three hours.

The 2022 CPI cycle was an outlier. When inflation and rate expectations dominated market psychology, CPI days registered 79 percent more volatility than other weekdays. Outside that window, daily volatility around announcements does not exceed typical levels.

Options expiries—long flagged as potential flash points—tell a different story. Since U.S. spot Bitcoin ETF launches in January 2024, expiry Fridays have run 25 percent less volatile than other Fridays. The December 26, 2025 Deribit settlement, a record $28.5 billion in combined Bitcoin and ether contracts, moved BTC just 0.31 percent in the 30 minutes after 8 a.m. UTC execution.

European Central Bank decisions showed mild but statistically insignificant impact on Bitcoin price movement. Bank of Japan decisions registered no measurable effect.

U.S. tax deadlines did not correlate with increased volatility, though Bitcoin weakness tended to precede April in years following major rallies.
