Bonds issued by the region's non-financial borrowers are headed for their best quarter since 2009, returning 3.33 percent since the end of December, according to the Bank of America Merrill Lynch index. Similar securities in the U.S. have gained 0.19 percent, a separate index shows.

The extra yield investors demand to buy euro-region company debt instead of German government securities narrowed 61 basis points since December to 140, or 1.4 percentage points. Spreads in the U.S. have dropped by 45 to 160.

The flood of issuance continued today with BAA Funding Ltd., owner of London's Heathrow airport, Neste Oil Oyj and RCI Banque SA, Renault SA's financing unit, in the market with bond sales.

“What we're seeing right now is a continuation of that positivity after the Greek deal,” said Juan Esteban Valencia, a credit strategist at Societe Generale SA in London. “Spreads are tightening and yields are very low so it's making it very attractive for issuers to come to the market.”

Elsewhere in credit markets, American Express Co. plans to sell $1.5 billion of five-year notes, according to a person with knowledge of the transaction. The notes may yield 130 basis points more than Treasuries of similar maturity, said the person, who declined to be identified because terms aren't set.

Noble Group

Noble Group Ltd., Asia's biggest listed commodities trader by sales, will delay marketing a $1.5 billion loan in general syndication, according to three people familiar with the matter.

The company had planned to start marketing the loan in general syndication today however some lenders approached to be arrangers or senior banks requested more time to prepare, the people said, asking not to be identified because the details are private. The original deadline for potential arrangers to respond to terms sent by Noble was last week. Some banks requested extensions in order to process internal credit approvals, the people said.

“There is no delay in our timetable,” Jeanny Kim, Noble's Hong Kong-based director of capital markets, said in an e-mail today. A public announcement will be made in due course, she said.

ECB President Mario Draghi gave banks more than 1 trillion euros ($1.31 trillion) of three-year loans in December and February through its Long-Term Refinancing Operation bolstering the financial system.

At the same time, an auction to settle outstanding credit- default swaps tied to Greece debt this week ended more than two years of speculation over whether the derivatives are reliable for insuring sovereign debt after European policy makers sought to prevent payouts on concern they'd worsen the region's crisis.

“Europe has put in place a multi-pronged effort to buy time and address the core issue of sovereign indebtedness and embedded losses in bank balance sheets,” said Marrinan at Royal Bank of Scotland.
