The European Union drew record demand for its debut green bond, in the sector’s biggest-ever offering. The bloc registered more than 135 billion euros ($156 billion) in orders Tuesday for a sale of 12 billion euros of securities maturing in 2037. Both the demand and size eclipse last month’s debut from the U.K. The transaction is just the first in a 250-billion-euro program of EU green-bond sales earmarked for the coming years. “This will be the largest green bond out there and it will provide investors with one of the most -- or the most -- liquid green bonds,” said Julian Kreipl, a credit analyst at UniCredit SpA in Munich. EU pulls in record $156 billion orders for debut green bond The jostle for orders was an “absolute riot,” according to Kerr Finlayson, the head of the frequent borrowers group syndicate at NatWest Markets Plc in London. The EU also holds the overall debt-market record, with 145 billion euros of orders for a social bond debut last year.
