Moments ago the gates arrived, when following a close 3-2 vote (with republican commissioner Piwowar and democrat Stein dissenting), the SEC adopted new rules designed to curb the risk of investor runs on money market funds, capping the end of a years-long heated debate between regulators and the industry dating to the financial crisis according to Reuters.

Among the changes, funds will have to switch to a floating share price instead of the current $1/share (hence the term breaking the buck). But the key part: "The SEC's rule will require prime money market funds to move from a stable $1 per share net asset value, to a floating NAV. It also will let fund boards lower redemption "gates" and fees in times of market stress."

And therein lies the rub, because the very presence of the "gate" effect will be enough to send money market investors rushing out (as they are all sophisticated enough to know that this fake, rigged market is a house of cards just waiting to come down) and into other asset classes.
