Argentina will announce on Monday a new round of emergency government measures, including raising interest rates 600 basis points to 97 per cent, to try to stave off the country’s worst economic crisis in two decades.

The Peronist government is desperate to avoid a big devaluation before elections in October. But the South American country is also running out of foreign exchange reserves as Argentines abandon the fast-devaluing peso and embrace the US dollar.

Fuelled by money-printing to finance a large government deficit, Argentine inflation hit 109 per cent a year in April, the highest level since 1991. The economy ministry said the new measures, to be announced Monday, would involve the central bank stepping up intervention in the foreign exchange market to try to slow the peso’s fall.
