Revenue vs. General Obligation
There have been recent debates within the industry about the "fading strength" of general obligation bonds. Some market participants now prefer revenue bonds, as one trader said "once you identify a revenue stream, it never goes away. I would call revenue bonds more dependable than GOs, as once you build tolls, people don't stop driving but with GOs, they cannot stay true to their 'full faith of credit' word."
Marilyn Cohen, chief executive officer at Los Angeles-based Envision Capital Management, said she believes the rules about state and locality GOs have changed from those she learned earlier in her career.
"There's been a big tectonic shift," Cohen said. "No longer are general obligation bonds the holy grail like we were taught."
Over the past two years, there has been more issuance of revenue bonds than GOs. In 2016 to date $246.8 billion of revenue bonds were issued, compared to $223.8 billion in 2015. Those numbers are well above the GO total of $175.9 billion this year and $153.8 billion in 2015, according to data from Thomson Reuters.
"About 95% of our funds are revenue bonds, but I think GOs have been mispriced in the muni market for a long time," said David Hammer, head municipal portfolio manager at PIMCO. "You get a wider value with revenue bonds and they tend to be more secure. In the stressed GOs you have seen some second guessing, but the stronger-credit GOs you don't second guess."
Bond Buyer Visible Supply
The Bond Buyer's 30-day visible supply calendar increased $474.6 million to $6.39 billion on Friday. The total is comprised of $1.27 billion of competitive sales and $5.12 billion of negotiated deals.
Primary Market
There are no deals larger than $100 million scheduled for the rest of the calendar year. On Friday, the market will be open for an abbreviated trading session, with an early 2 pm close.
