The municipal-bond market has shown some optimism recently that Illinois and Chicago will ultimately tackle their huge pension burdens. But one of the biggest buyers of state and local government debt isn’t so sure, Bloomberg News reported. Franklin Templeton Investments, which manages more than $60 billion in municipal securities, said it won’t buy uninsured general-obligation bonds from Illinois and any debt from Chicago and the city’s public school system, citing the threat from “pension beasts.” “Will Illinois’ governor and Chicago’s mayor eventually impair bondholders rather than push for sensible pension reforms? We think it’s more likely than not, unfortunately,” Franklin analysts led by Sheila Amoroso wrote in a blog post. The comments buck the broader sentiment in the market, where Illinois bonds have rallied this year on optimism about Governor J.B. Pritzker’s plans to mend the state’s finances, in part by scrapping the flat income tax to raise more revenue. But state and local politicians’ focus on levying new taxes or selling assets such as land won’t make the math work to solve a pension problem that for Illinois is a “fire-breathing monster that dwarfs Illinois’ revenue-generating capacity,” the Franklin analysts wrote.
