The King of Risky Hometown Bonds Is Back

It seemed as though John Miller’s luck was running out.

Buying the riskiest bonds in the $4 trillion market for state and local debt had made Miller a power player in a corner of Wall Street often derided as staid and boring. But the 2022 bond rout drained billions from his flagship high-yield fund at Nuveen. Last year, on Miller’s 56th birthday, the trillion-dollar asset-management company abruptly announced plans for his departure.

Now, Miller is on the rebound. He joined forces with a boutique firm, recruited a handful of analysts and traders and, earlier this year, started a fund from scratch. Money is pouring in: about $3 billion this year through August, according to Morningstar Direct.

The lanky fitness buff, whose latest hobby is riding an electric hydrofoiling surfboard, reflected on the changes on a recent Thursday from his new office at First Eagle Investments’ Chicago location. It’s just a few blocks south of Nuveen’s glass tower, where Miller used to supervise more money in municipal bonds than First Eagle manages in total. That fits with his new investing philosophy, he said: Bigger isn’t always better.

“I think that I could have the best team and best job in muni high-yield once again,” he said. “That’s very feasible.”

One big question is how Miller will fare in a shakier, higher-rate economy. The new First Eagle fund has trounced many other high-yield muni investments so far by leaning into risk. Morningstar data show that, as of June 30, more than 8% of the fund was invested in the Brightline, a private railroad running up the coast of car-centric Florida.

That kind of move helped Miller build Nuveen into the biggest manager of muni junk bonds—controlling about a fifth of high-yield mutual fund holdings—during a decade of cheap money and economic expansion. Investors frustrated by low rates on ultrasafe city and school debt warmed to munis backed by nursing homes, charter schools and casinos. But analysts say credit is weakening. According to Municipal Market Analytics, a 10th of outstanding nursing-home debt is currently in default.

“John Miller runs, and has historically run, a fairly high-octane muni strategy,” said Nicholos Venditti, head of munis at Allspring Global Investments. “If you believe ‘economic slowdown,’ if you believe ‘recession,’ if you believe that kind of thing, you may want a strategy that is less high-octane all the time.”
