India's asset-backed securities market reached a record as global banks increased purchases to gain exposure to one of the world's fastest-growing major economies. Crisil Ratings chief rating officer Krishnan Sitaraman said foreign banks' share of total bond issuance rose to about 35% in the fiscal year to March, up from roughly 28% and 30% in the prior two years. With annual ABS issuance of 1.53 trillion rupees (about $16bn), that implies overseas lenders purchased roughly $5.6bn of bonds. People familiar with the matter said Barclays, Citigroup, JP Morgan and Standard Chartered were among the foreign banks boosting allocations to the sector.
