A couple of quarter of all US infrastructure is prone to critical flooding, new analysis reveals, which might hit costs within the $4tn municipal bond market and jeopardise the creditworthiness of metropolis and state issuers.
New York-based local weather analysis agency First Road Basis this week published data exhibiting that US infrastructure — together with roads, hospitals and energy stations — is at a larger threat of flooding than has beforehand been estimated. This has critical implications for state and metropolis coffers, for property values, and for mortgage-backed securities and municipal bonds.
Louisiana, Florida and West Virginia have a few of the worst flood prospects within the contiguous US, the First Road Basis information present. In Louisiana, 45 per cent of all crucial infrastructure amenities, a class which incorporates hospitals, fireplace stations, airports and energy crops, are prone to being rendered inoperable by flooding this yr.
Additionally prone to shutdown are 39 per cent of roads and 44 per cent of social infrastructure — colleges, authorities buildings and homes of worship. In some cities in Louisiana, comparable to Metairie and New Orleans, the danger for all these classes is close to 100 per cent.
Municipal debt has lengthy been a haven asset class, well-liked with long-term buyers together with pension funds and insurance coverage firms. Whereas the default fee on muni bonds has traditionally been low, it might rise as cash-strapped cities wrestle to maintain up with the prices of maximum climate injury.
Muni bonds additionally are inclined to have maturities between 15 and 30 years; the typical muni maturity issued final month was 18.6 years, based on the Securities Business and Monetary Markets Affiliation. With the local weather altering so shortly, that leaves a variety of time for catastrophe to strike.
Buyers additionally face the danger of geographic focus. Proudly owning munis issued by the state wherein you reside affords buyers sure tax advantages, so muni buyers are inclined to have excessive levels of publicity to sure areas. A extreme climate occasion might due to this fact shortly wipe out an enormous quantity of worth in a muni portfolio.
“It’s clear (local weather) is a threat issue” within the municipal debt market, mentioned Peter DeGroot, head of municipal bond analysis at JPMorgan. “The growing frequency and depth of climate occasions is a expensive and sophisticated subject for the federal authorities — and for state and native governments as nicely.”

Flooding can have an effect on municipal debt in numerous methods. There’s the direct impact: a muni bond issued to fund the development of a hospital might fall in worth or threat default if its income stream ends abruptly when the hospital is destroyed in a storm.
Pure disasters can even drive individuals and companies away and decrease the worth of current property, diminishing a state or metropolis’s tax base, one other means that muni bonds are paid off.
Widespread flooding can be enormously costly. Between 1980 and 2020, pure disasters brought about $1.8tn price of harm, based on the Government Accountability Office, roughly half of which was associated to hurricanes and tropical storms. Municipalities need to borrow extra with the intention to pay to rebuild, and to construct new local weather adaptation infrastructure. That raises the credit score threat of current bonds in addition to the price to borrow new funds.
Research led by Paul Goldsmith-Pinkham at Yale College reveals that municipal bond markets have already begun to cost within the dangers of upper sea ranges.
The federal authorities has till now stepped in to assist cities rebuild after main disasters. However as these occasions turn into extra frequent, assets could be strained and native governments could bear extra duty for funding restoration efforts.
Of the highest 10 states with the best infrastructure flood threat, two are additionally among the many most indebted: Connecticut and New York. Connecticut has the best web tax-supported debt per capita out of all 50 states, the second-highest web tax-supported debt as a share of private earnings and the second highest web tax-supported debt as a share of state gross home product, based on credit standing company Moody’s. New York is inside the prime 10 in every of these classes as nicely.

One of many two municipal debt defaults in 2020 — albeit not pushed by local weather prices — was in New Orleans, town with the second-highest flood threat within the nation. In Stockton, California, one of many largest cities to ever declare chapter, 75 per cent of crucial infrastructure amenities and 94 per cent of its social infrastructure is prone to flooding this yr.
“With a variety of these local weather dangers, we’d not need to purchase a small metropolis on the coast that has a excessive threat of flooding, however we may be comfy with proudly owning a bigger title with a greater steadiness sheet for a shorter interval, as a result of we’ve got to consider learn how to truly value that calculated threat,” mentioned Alexa Gordon, a portfolio supervisor and head of muni ESG at Goldman Sachs.
All three main US score businesses — Moody’s, S&P and Fitch — have begun to include local weather threat into their municipal debt evaluations.
“Our analytical view has been that flooding is akin to different dangers {that a} state or native authorities may very well be challenged with,” mentioned Marcy Block, senior director of sustainable finance at Fitch Scores.
“To the extent the danger of flooding turns into a credit score threat because it’s past administration’s means to successfully management, that will be mirrored in our scores and our ESG relevance scores.”
