when the bank of Japan intervenes to prop up the yen that means that they are buying yen

they're buying it with t-bills of which they have an enormous stack, trillions of dollars worth

so they're selling t-bills to buy their own currency, trying to move it from 150 yen to the dollar to 140 yen per dollar

if they sell their t-bills, who buys them? is it a fire sale? because that would push down the value of those bonds which makes interest rates go up

Congress is creating a lot of debt which means lots of t-bills are getting created

what percentage of the market constitutes the bonds that Japan is selling?

help me Lyn Alden, you're my only hope
