IMF, what are tariffs on billions of trade, when compared to tariffs and subsidies on trillions of bank credit?

Sir, Chris Giles, James Politi and Stefania Palma write about concerns during recent IMF meetings in Bali, “With the world’s two largest economies slapping tariffs on $360bn of goods so far this year, and possibly more to come” “Geopolitical tension casts pall over annual IMF meeting” October 15.

Last year I read somewhere that the just world’s 10 largest banks combined had over $25 trillion in assets. So when I think on how much the allocation of those assets might be dangerously distorted by the risk weighted capital requirements, I find it hard to understand that “the world’s two largest economies slapping tariffs on $360bn of goods so far this year”, was of so much concern during the recent IMF meetings

Sir, get it, the risk weighting of banks’ capital requirements, for bank protection purposes, translates de facto into tariffs and subsidies that will steer the allocation of bank credit.

The damage, by promoting banks way too much to be into banks “safe” AAA rated securities, residential mortgages and loans to sovereigns, while de-incentivizing loans to “risky” entrepreneurs and SMEs, is immensely worse than what the current trade-wars, sort of Lilliputian vs. Blefuscu in comparison, could produce.

Sir, again, for the umpteenth time, what the risk weighted capital requirements for banks guarantee is: 

Especially large exposures to what’s perceived as especially safe, against especially little capital, which dooms or bank system to especially severe crises. 

Especially low exposures to what is perceived as risky, like loans to entrepreneurs and SMEs, which dooms our economies to weakness and to not being able to reach their potential.
