A market-mover headline needs two separate pieces of evidence: the event happened, and the asset moved over a specified interval. The Fed’s September 16 statement documents the event. It does not, by itself, establish how much of any later crypto or equity move was caused by that decision.

What the evidence shows

The word 'because' is a strong editorial claim. A release followed by a move establishes sequence, not exclusive causation. To attribute a catalyst responsibly, compare the asset with peers, inspect the minute-by-minute timing and rule out simultaneous macro or project news.

Volume and order-book depth help assess whether a move had broad participation. A small token may show a large percentage swing on little notional turnover. A rate announcement can already be reflected in prices, so the surprise relative to expectations matters more than the calendar event alone.

Why it matters

Measure the asset on the same venue and in the same time window as the claimed catalyst. Compare peers, liquidity and broader market direction. If a token moves in thin trading while similar assets do not, the cause may be idiosyncratic or unverified.

Deeper context and limits

Market reactions also depend on what was expected. A company can beat its own prior result yet miss investor forecasts, or a regulator can announce a widely anticipated measure that produces little immediate movement. Before writing 'asset surged on news,' compare the event time with the first notable price and volume change and ask whether the market had advance signals.

An order-book snapshot can help identify whether reported capitalization is supported by executable bids. For thin tokens, a small trade may produce a dramatic percentage quote. The more responsible presentation is a timestamped observed move, a named potential catalyst and a stated alternative explanation, rather than a confident causal claim without testing.

Confirmation and invalidation

State the baseline, interval, venue and comparison basket. Invalidate causal language if the timing or broader market contradicts it.

Publish price source, timestamp, baseline and competing explanations. If the causal link is uncertain, describe the coincidence without claiming proof.
