CPI Fell 0.4% in June. Check Which of Your Leases Noticed.
The print
The consumer price index fell 0.4% in June on a seasonally adjusted basis, the biggest monthly decline since April 2020. Energy dropped 5.7% as oil gave back part of its spring rise. The annual rate came in at 3.5% against a 3.8% forecast. Core inflation was flat for the month. The Fed left rates alone, the CRE Finance Council's sentiment index steadied at "cautious," and office demand finished its second positive quarter after four years of losses.
What a negative month does to an indexed lease
Most CPI escalations adjust annually using the index value from a reference month, often the month before the anniversary. A single negative monthly print does not lower the annual figure below zero, so a lease adjusting on a July anniversary still sees an increase of about 3.5%. A lease with a 3% cap gets 3%. A lease with a floor gets whichever is higher.
The traps are in the details. Some leases use the "CPI-U, All Items" index and some use "All Items less Energy." Those two indexes moved in opposite directions this spring. Some leases adjust on the change from the base month at lease commencement rather than year over year, which means a tenant who signed in 2020 has accrued a 25% cumulative increase and is not going to like the reminder. And some leases, particularly older retail leases, adjust only upward and never downward, which the tenant's lawyer will find the first time the index falls.
What to do before the anniversary dates
Pull every lease with an index clause and put four things in a table: the index named, the reference month, the cap or floor, and the adjustment date. Then compute the adjustment yourself before the accounting system does. We have seen property management software apply the wrong index series for years without anyone checking, because the number looked plausible. A 3.5% versus 2.5% error on a $500,000 rent is $5,000 a year, compounded for the rest of the term.
Lease abstraction tools produce that table from the lease files in a day, with each clause linked to its page. Then the calculation runs from the abstract rather than from memory, and the wrong-index error stops happening. For a portfolio with 80 indexed leases, that is a week of property accounting time returned every year and a class of billing error removed for good. The audit that used to find it three years later, with interest, no longer has anything to find.
Send tenants the calculation with the notice. A one-page memo showing the index values, the formula and the result prevents the dispute that a bare "your rent is now $X" letter invites. Tenants who can check the math pay it.
For the leases you are negotiating now
Inflation at 3.5% with a Fed leaning toward a hike is a market where a fixed 3% bump favors the tenant and an uncapped CPI clause favors the landlord. The compromise that gets signed this year is CPI with a 2% floor and a 4% cap. Landlords should also push for the All Items index rather than the core index, because energy is the component doing the moving, and a landlord's own costs move with it.
