Bitcoin Faces Volatility Risk as Asian Holidays and U.S. Shutdown Collide

The world’s largest cryptocurrency enters October under unusual pressure, with analysts at K33 Research warning that seasonal trading lulls in Asia, combined with disruptions from the U.S. government shutdown, could unsettle Bitcoin’s price action in the coming days.

Golden Week Historically Brings Flat Performance

China’s Golden Week holiday, which began October 1 and runs through October 7, coincides with South Korean market closures from October 3–9, as well as other Asian breaks. This lull in regional participation has historically dragged on Bitcoin performance, with K33 data showing that the first week of October typically delivers flat or negative returns.

“BTC typically behaves flat during the early October Asian holiday season,” wrote Vetle Lunde, Head of Research at K33, noting that volatility often compresses toward local lows. The 2021 rally, however, was a rare exception, bucking the seasonal pattern with outsized gains.
Lunde also pointed out that this isn’t just about holidays: August through mid-October tends to be one of Bitcoin’s weakest stretches of the year in terms of directional momentum.

Shutdown Adds Fuel to Uncertainty

This year, the macro environment adds further complexity. On Wednesday, the U.S. government entered a partial shutdown after lawmakers failed to pass a funding bill. The move halts non-essential services, furloughs federal workers, and delays critical economic data releases such as jobs reports and inflation numbers.

According to K33, the lack of timely U.S. macro data may thin order books further, exposing traders to sudden swings. “Erratic price action” is particularly likely during overlapping sessions in the first half of October, Lunde warned.

Asia’s Consistent Underperformance

K33’s research highlighted that Asia has been a persistent drag on Bitcoin returns. Year-to-date, compounded returns during Asian trading hours are –9.7%, with the region underperforming both Europe and the U.S. every year since 2021, except for a brief outperformance in 2022.

Much of Bitcoin’s upside momentum has instead emerged during U.S. trading hours, particularly after the launch of spot ETFs. “Profit-taking and mean reversions in Asian hours amid lower relative liquidity may explain the Asian session’s clear underperformance,” Lunde explained.

Outlook for October

As Bitcoin navigates a quiet Asian backdrop and delayed U.S. economic signals, the early weeks of October could set the tone for Q4 trading. With order books thinner than usual, even modest inflows or outflows may produce outsized volatility — leaving traders to watch whether this October resembles the flat lulls of prior years or breaks the pattern, as it did in 2021.
