Latest / Inflation Explained with Fexingo: CPI, Prices, and the Cost of Living for Everyday People / Why the Fed Ignores the Rent You Actually Pay
Transcript
- Lucas: So the May CPI came in at 334.0, up from 332.41 in April. Shelter inflation was 4.6 percent year-over-year — still uncomfortably high. But here's the thing that's been bugging me: the rent number the CPI reports is not the rent you actually pay. Luna: Right, because the BLS doesn't just go out and survey what new tenants are signing. They track what existing tenants are paying, and they use something called Owners' Equivalent Rent for homeowners. Lucas: Exactly. Owners' Equivalent Rent — OER — is about a quarter of the entire CPI basket. It's the BLS asking homeowners, 'If you rented your home, what would it rent for?' And that hypothetical number moves like molasses. Meanwhile, real market rents — the ones on Zillow, Apartments.com — have been jumping 8 to 12 percent in cities like Phoenix, Austin, and Nashville. Luna: I saw a report that Zillow's Observed Rent Index for Phoenix was up 11.2 percent year-over-year in May. The CPI rent index for the same metro? Something like 4.1 percent. That's a seven-point gap. Lucas: That gap matters because the Fed watches CPI and PCE to set rates. If the official data says shelter inflation is 4.6 percent, but real rents are running above 10 percent in major metros, then the Fed is making policy on a lagging signal. Luna: And that lag is structural. The BLS samples a panel of rental units and only rotates a sixth of them every six months. So a lease signed today at a higher rate won't even enter the index for maybe a year. Lucas: Let me give you a concrete example. There's a landlord in Phoenix — I'll call her Maria — who owns a 12-unit building. In June 2026, she raised rent on a two-bedroom from $1,400 to $1,550 — an 11 percent increase. That new lease won't be captured in CPI until her unit is surveyed, possibly in early 2027. By then, the Fed might have already cut rates based on misleadingly low inflation data. Luna: So the Fed could cut rates into a housing market where real rent inflation is still 8 or 10 percent. That's a recipe for a second wave of housing cost pressure. Lucas: And it's not just Phoenix. The Dallas Fed did a study last year showing that the gap between market-rate rent indexes and CPI rent was at a historic high — about 5 percentage points nationally. That gap has persisted into 2026. Luna: Why doesn't the BLS just use market-rate data? They have access to it. Lucas: Good question. The BLS is methodologically conservative — they want a consistent, unbiased measure that captures the experience of all renters, not just the ones who move. About 70 percent of renters stay in place year-over-year, and their rents increase more slowly. So CPI rent reflects that majority. But for the 30 percent who move, the increase is much steeper. The CPI just averages it out. Luna: Which means if you're a renter who moved in 2025 or 2026, your personal inflation rate is way above the official number. And you're probably frustrated when you hear 'inflation is cooling.' Lucas: Right. And this feeds into the broader narrative around the Fed's credibility. If the public perceives that official inflation understates their actual cost of living, you get an expectations problem. The New York Fed's Survey of Consumer Expectations last month showed one-year-ahead inflation expectations at 3.8 percent — well above the 2.2 percent breakeven in the bond market. Luna: That gap between household expectations and market expectations is exactly the kind of thing that makes the Fed's job harder. If people think inflation is higher than it is, they demand higher wages, and that becomes self-fulfilling. Lucas: Exactly. And the BLS methodology isn't wrong per se — it serves a purpose. But when you have a Fed that says 'we're data dependent,' we need to ask: which data? The lagging data or the real-time data? Luna: To be fair, the Fed does look at other indicators. Chair Powell has mentioned Zillow and Apartment List in press conferences. But the formal models still rely on CPI and PCE. Lucas: True. And the PCE — which is the Fed's preferred gauge — uses a different rent calculation. It incorporates more data sources, including the BLS' own tenant survey, but it still has a similar lag. The Core PCE just came in at 3.4 percent for May, the highest since October 2023. Shelter is a big part of that. Luna: So what's the takeaway for someone listening? Should they expect rent to keep outpacing CPI for the rest of 2026? Lucas: Probably, yes. The multifamily construction boom of 2022-2024 is delivering units now — completions hit a 50-year high last year. That should eventually cap rent growth. But the pipeline is slowing. Starts have dropped sharply as construction financing got expensive. So the supply relief may be short-lived. Luna: And meanwhile, demand is still strong. Wages are growing 4 to 5 percent, people need housing, and household formation is up. Lucas: Right. So the pressure is there. My bet is that CPI rent will gradually drift higher over the next 12 months as the market-rate increases bleed into the index. But by the time it peaks, the real market might already be cooling again. That's the lag problem in a nutshell. Luna: It's almost like the CPI is looking in the rearview mirror while the Fed needs a windshield. Lucas: That's a good way to put it. And it's not just rent — the same dynamic plays out in other sticky categories like insurance and medical services. But rent is the heavyweight, and it's the one with the most chronic lag. Luna: You know, I think a lot of our listeners are renters who feel gaslit by the official numbers. They see their rent go up $200 and then hear 'inflation is down to 3.3 percent.' Lucas: And that disconnect erodes trust. Which is why shows like this exist — to explain how the sausage is made. And if walking through the economy with us has made something click, it's worth mentioning that listener support is what keeps this show ad-free and independent. You can support us at buy me a coffee dot com slash fexingo. No pressure, but it helps us keep digging into these gaps. Luna: Yeah, even a small contribution goes a long way. We're not backed by a big network, so it really is listener-driven. Lucas: Absolutely. Now back to the lag — there's actually a proposal from some economists to create a 'real-time rent index' that the Fed could use alongside CPI. It would pull data from property management software and listing sites. But the BLS has resisted, citing quality control issues. Luna: Is there any movement on that? Or is it stuck in bureaucratic debate? Lucas: There's a pilot program at the BLS — they're testing a new rent index using data from Yardi Systems. Early results show the gap closing a bit, but they haven't published it officially yet. It could be a game-changer if they adopt it. Luna: So maybe in a year or two, we'll have better data. But for now, renters are stuck with a lagging official number. Lucas: Exactly. And that's the story we'll keep tracking. Next time, we'll look at how auto insurance inflation is behaving — another category where the official number and the real-world experience are miles apart. Luna: Looking forward to it.
