The usury point has exceptions for trade financing etc:
"ยง 5. Whoever lends money, transfers the dominion of the money to the borrower. The latter therefore holds it at his own risk, and is bound to restore the sum in its entirety: wherefore the lender ought not to exact any more. But he who entrusts his money to a merchant or manufacturer in the way of partnership, does not transfer the dominion of the money to him, but it remains his: so that at his risk it is that the merchant trades with it, or the manufacturer works upon it: and therefore at that rate he may lawfully demand a share of the profits thence arising as from his own property.1"- Thomas Aquinas
