In the thirty minutes after the FOMC decision on 18 Mar 2026, the Nasdaq 100 swung 0.36% from its high to its low, smaller than the typical 0.50% across all 25 the FOMC decision releases measured here (the 19th largest). It ended the half hour down 0.10% from the release price. By the 16:00 ET close it was down 0.92%, back across the release price from the first five minutes.

Signed moves from the release price, in percent. Usual distance is the median size of the Nasdaq move at that mark across all 25 the FOMC decision releases, without its sign; the swing row compares like with like.
The Nasdaq 100 index CFD, one-minute bars, as percent from the last price before the release. Above the centre line is up.
The first five minutes went up 0.10%. At the 16:00 ET close the Nasdaq 100 was down 0.92% from the release price, so by the measure on the the FOMC decision page this release was a reversal: the close was across the release price from the 5-minute mark. That compares two moments, not the path between them.
