​For more than a decade, Argentina was a financial pariah. A long-running dispute with holders of its defaulted debt left it shut out of global credit markets and shattered its reputation as a place for business. President Mauricio Macri’s decision to pay $9.3 billion to the creditors resolved the first problem. But the flood of foreign investment that he promised would follow has so far proved more of a trickle. Last week the government organised a “mini Davos” in Buenos Aires, hosting executives from around the world. The proactive approach is bearing fruit: today the Export-Import Bank of the United States will resume offering financing in Argentina after a 15-year absence. But more needs to be done. Although foreign firms have announced $30 billion of investments since December, only $1.3 billion materialised in the first half of the year. Rehabilitating Argentina’s image is taking longer than Mr Macri had hoped.
