Governments have been hit hard, too. Fitch has made a record number of sovereign downgrades -- 32 rating actions affecting 26 sovereigns -- including pushing two of the biggest borrowers, Italy and Mexico, into the danger zone. More than a third of its 118 sovereign grades are also still on downgrade warnings.
S&P has made 19 sovereign downgrades and 31 outlook cuts, while Moody's estimates the virus will push up debt in the world's richest nations by close to 20 percentage points on average, almost double the damage done by the financial crash.
S&P's count of fallen angels, or issuers downgraded to junk ("BB+" or lower) from investment grade ("BBB-" or higher) has hit 34 issuers with over $320 billion in rated debt among them, including Ford, Rolls-Royce, Kraft Heinz, Renault, Delta Air Lines, Lufthansa, British Airways and Macy's.
