Why are tariffs on trade with others, worse than tariffs on access to bank credit for your own?

Sir, I refer to Martin Wolf’s spirited defense of free trade and not less spirited attack on Donald Trump for having turned the US into “a rogue superpower, hostile, among many other things, to the fundamental norms of a trading system based on multilateral agreement and binding rules.” “The US-China clash challenges the world” May 22.

Do I disagree? Not really, except noting that at least Trump follows the instinct to protect his own.

But where was/is Martin Wolf when bank regulators, for instance, with Basel II, require banks to hold 8% in capital when lending to their own unrated entrepreneurs, but allow his banks to lend to any other sovereign AAA to AA rated against no capital at all, or to any other foreign AAA to AA rated entrepreneur against only 1.6% in capital?

Sir, anyone who argues those differences in capital requirements are not de facto tariffs on the access to bank credit, have no idea of what they are talking about.

Truth is that since trade is about today, but credit is about tomorrow, I truly believe the Basel Committee and their affiliate regulators are, with their tariffs on the access to bank credit, doing much more damage than a Donald Trump.

But of course you dare not to favor the opinion of little me over that of your own chief economic commentator.
