New customs might incite them

TRADEWARS

Think of conflicts that arise when countries impose tariffs or restrictions on imports and exports, often leading to economic tension.

"New customs" hints at tariffs—taxes on imported goods—while "might incite" suggests conflict or rivalry. Combine the idea of trade disputes with the word "wars," and you get TRADEWARS, a term for economic battles sparked by changes in trade policies or tariffs. The clue plays on both the literal meaning of customs (trade duties) and the figurative "war" that can follow.
