Puerto Rico triggers historic default as austerity spiral deepens

America’s home-grown “Greece” is trapped in a vicious circle as a shrinking economy and an exodus of workers pushes the debt ratio through the roof

Puerto Rico has triggered the biggest municipal default in US history, risking years of bitter legal warfare with creditors and an austerity “death spiral” with echoes of Greece.

The island Commonwealth finally ran out of money on Monday after a desperate effort to stay afloat, and missed a final deadline for a $58m payment – handing over just $628,000.

It implies a sweeping default on much of its $72bn debt burden, equal to 100pc of Puerto Rico’s gross national product (GNP) and more than five times the debt ratio of California or Texas.
