Bitcoin moved toward its weakest level in roughly eleven weeks after US consumer price data for October came in hotter than economists had projected. Wire reports on the release said US stocks also lost ground at first, as investors absorbed figures that pointed to inflation pressure proving stubborn.

The core measure, which strips out food and energy and is closely followed as a guide to underlying price trends, rose 0.3% on a month-on-month basis in October. That marked the third straight month at that pace. Forecasters had anticipated a smaller gain of 0.2%, so the print landed above consensus and reinforced the view that underlying price growth is not fading as quickly as hoped.

The headline index showed some cooling. Overall consumer prices climbed 0.4% over the month, a step down from the 0.6% increase recorded previously. Even so, coverage of the release indicated that the headline reading was also not as soft as had been expected, so the moderation did little to offset the surprise in the core figures. One description of the data in the reporting characterized the inflation beat as discouraging for risk assets.

The data matters because of its link to Federal Reserve policy. According to the reporting reviewed by FXMARE, traders were positioned for a quarter-point rate hike at the central bank's December meeting. Consumer price inflation is one of the main inputs the Fed weighs when setting borrowing costs, and an upside surprise in the core component tends to draw particular attention because it reflects price trends that are slower to reverse.

Bitcoin has often traded in sympathy with US equities around major macroeconomic releases, and the initial reaction followed that pattern, with both falling after the numbers crossed the wires. The sources do not provide specific price levels for bitcoin or for the stock indexes, and they describe the moves as initial reactions rather than a settled direction for the session.

The October report adds to a run of three consecutive 0.3% core readings, a sequence that underscores how persistent the underlying component of US inflation has been, even as the headline figure eased from the prior month's faster rise.

Why it matters for traders

Inflation data that exceeds forecasts can shift expectations for Federal Reserve policy, and that in turn influences appetite for risk assets such as bitcoin and equities. The reporting shows markets already leaning toward a December quarter-point hike, so the core reading's persistence is closely watched. Traders in crypto and stocks track CPI releases because they can move both markets at the same time.
