ATLANTA — Industrial real estate construction across the Sun Belt's major distribution markets has, in the most recent quarter, outpaced tenant absorption for the first time since 2017, marking a turning point for the sector that has been one of the most consistent stories of the post-pandemic real-estate cycle.

Vacancy rates have ticked up across Atlanta, Phoenix, and Dallas, the three markets that have been the dominant absorbers of new industrial supply through the past four years. The increases are modest in absolute terms but they break a pattern that had, for sixteen consecutive quarters, been one-directional.

What the data shows

The aggregate Sun Belt industrial vacancy rate moved from 5.4 percent at the end of last quarter to 6.2 percent at the end of the most recent quarter, the largest single-quarter increase since the pandemic-onset disruption of 2020 distorted normal market behaviour for several quarters in succession.

The increase is concentrated in newly-completed buildings of larger size brackets — properties above 750,000 square feet have absorbed the largest share of the increase. Smaller buildings continue to lease at a pace closer to the pattern of the past several years.

Why the shift

The shift reflects the working-out of two patterns that had been visible in the underlying data for at least eighteen months. The first is the cooling of the post-pandemic logistics demand surge that had, in the immediate aftermath of the disruption, produced absorption rates that were always going to be unsustainable.

The second is the catch-up of the industrial construction pipeline, which had, in 2022 and 2023, produced building starts at rates that priced in continued strong absorption. The construction pipeline, having been started, has continued to deliver buildings even as the demand environment that justified the starts has cooled.

The pricing implication

Industrial rents have, on the markets-tracker data, moved from sustained increases to a flatter pattern over the past two quarters. Renewal rents in the affected markets have, in some cases, moved below the rates achieved on the prior leases — a development that the sector had not seen in any meaningful volume during the past four years.

The pricing softening is, on the underlying analysis, more consequential for the next cycle of construction starts than for current operating economics. Lenders who underwrite industrial development have begun to apply more conservative rent assumptions to new project pro-formas; the resulting reduction in starts will, on its own, eventually rebalance the supply-demand picture.

What this means for the longer cycle

The longer-cycle implication is that the industrial market has entered a phase of more normal-cycle behaviour. The post-pandemic period produced absorption and rent dynamics that resembled boom conditions in past cycles; the current quarter is the first to suggest that the boom phase has ended and that the sector is entering a more standard middle-cycle pattern.

Whether the middle-cycle pattern resembles the cycles that preceded the pandemic distortion or whether it produces its own distinctive characteristics is one of the analytical questions the next several quarters will sharpen.
