(Bloomberg) -- Japanese consumer lender Aiful Corp. sold bonds with the world’s lowest coupon for a junk-rated issuer this year, as record low rates amid the pandemic redefine what high yield means.Aiful priced 15 billion yen ($144 million) of 1.5-year notes with a coupon of 1%, according to Nomura Securities Co., one of the underwriters. It’s the second-ever junk bond offered publicly in Japan’s local credit market, after Aiful priced the first such security last year at a lower coupon at 0.99%.Unprecedented stimulus from central banks amid the pandemic has dragged down rates, and left investors clamoring for debt that may help increase returns. The average yield on high-yield bonds globally has fallen 85 basis points this year to an all-time low of 4.83%, according to a Bloomberg Barclays index. A comeback in even the riskiest junk securities is gaining ground, narrowing the gap between lower-rated and higher-quality debt.Aiful, which teetered on the edge of bankruptcy a decade ago, has speculative-grade scores from local credit rating firms. The lender’s junk debt offerings are still the exception that proves the rule in Japan, where companies haven’t felt compelled to sell speculative-grade notes as they’ve traditionally found it easy to obtain bank loans.Read more about Japan’s nascent junk bond market hereAsiaAsian dollar bond spreads and credit-default swaps tightened Wednesday, with spreads on high-grade notes narrowing about 3 basis points, according to traders.
