Antisemitism is no longer reacting to events. When CST published its Antisemitic Incidents Report for 2025, we warned that the unprecedented levels of antisemitism seen since October 7 had not disappeared. Every month of 2026 has seen more than 200 incidents, while March, April and May each exceeded 350 reports. Antisemitism is no longer a temporary spike that flares up in response to major events before receding. For many British Jews, this is no longer an occasional concern.
