“These changes are being made to address highly unusual disruptions in Treasury financing markets associated with the coronavirus outbreak,” the New York Fed said in an early afternoon announcement amid a washout on Wall Street that was heading toward the worst day since 1987.

Stocks were off their lows following the announcement though some of the gains were pared as the market digested the moves.

One part of the announcement saw the Fed widen the scale for its $60 billion worth of money the Treasury purchases, which to now had been confined to short-term T-bills.

Under the new regime, the Fed will extend its purchases “across a range of maturities” to include bills, notes, Treasury Inflation-Protected Securities and other instruments.
