It would have been better to spell out "basis points" in the title, but the term is not at all obscure -- it's very widely used in the finance sector.
The original article doesn't even use bps. It just says "In support of these goals, the Committee decided to raise the target range for the federal funds rate to 5-1/4 to 5-1/2 percent"
The title could have just said "Fed raises rate from 5.25 to 5.50". That'd contained a lot more information.
How many times have you seen a post when the submitted article was scorned for not using accurate terminologies?
