Kernel, Ukraine’s top vegetable oil producer, has placed 7-year Eurobonds at 6.75% — 105 basis points below the yield for a sovereign bond. Deemed a better risk than the country it operates in, Kernel placed $300 million worth of Eurobonds on Tuesday. By contrast, Naftogaz, the state energy company, aborted a Eurobond sale Monday, saying the offered yield of 8.95% was too high.
