Significant Drawdown from Friday

Newbie question here. Advise if this is more appropriate in the Beginner Questions.

I’m experiencing a significant drawdown from Friday on the USDJPY pair. Attached is an M30 session showing when the news hit (red vert line). News is also attached. Looks like the drawdown didn’t take place immediate, instead about an hour after. Does news typically impact immediately or can there be a delay?
