People in my new workplace hold that "should" is less definitive than "would," for e.g., in the sentence:
Commodity prices could be depressed in 2016 due to oversupply, which should pressure power prices.
To me, "should" here indicates a certainty (that oversupply has a relation to power prices) given some condition (that has been (naturally) left unsaid).
Which word/verb/mood of the two is more preferable if the author's intention is to play safe?
