Hyphens, En Dashes, Em Dashes

Q. A bill has been proposed dealing with price gouging. Would it be correct to write Anti-Price Gouging Act or Anti-Price-Gouging Act? I have seen it both ways.

A. Although hyphens are often optional, I would hate to see a Gouging Act, even if it were an anti-price one, so I would use both hyphens. A fancier fix would be to use an en dash after “anti”: Anti–Price Gouging Act (per CMOS 6.80), although to my eye that still suggests a somewhat gory scene.

[This answer relies on the 17th edition of CMOS (2017) unless otherwise noted.]
