Just ten days ago, in the aftermath of the BOJ's -0.1% NIRP announcement, we reported that after more than one year after the ECB unleashed NIRP, the total number of government bonds with negative yields to a staggering $3 trillion, a number which nearly doubled overnight to $5.5 trillion.

Overnight in a historic event, the latest consequence of the BOJ losing control, the yield on Japan's 10Y JGB dropped below zero for the first time, in the process joining Switzerland as the only other country (for now) with a NIRPing benchmark 10Y treasury.

And, as Bloomberg calculates, this means that as of this moment, $7 trillion or about 30% of all sovereign bonds, are yielding negative rates, implying "investors" have to pay governments for the privilege of holding their money. It also means that in the past 10 days a record $1.5 trillion in global treasurys have gone from having a plus to a minus sign in front of their yield.
