In 1991, Alberto Echegaray Guevara was an advisor to the Argentinian economic minister who pegged the country’s currency at a 1:1 rate with the US dollar — a move some say contributed to the 2001 economic crisis, significantly devaluing the Argentine peso. Now it seems Echegaray has come full circle. His artistic debut at the arteBA fair last month under the pseudonym Cayman took on inflation as its subject.
