The Cost Index · week of 2026-06-18 · 5 min read · By Don Goldstein
Where the basket stands this week. What's flashing.
The restaurant cost index for the week of 2026-06-18: the weighted basket reads +3.2% against its baseline, 36 of 82 tracked ingredients above their own window. These are public wholesale levels, never your delivered price — a read on the market, so you can tell a real move from a vendor markup.
Here is the read I run on a Tuesday between the produce drop and the pre-shift, and it is the same read this dispatch carries. The cost index for the week of 2026-06-18 has the weighted basket sitting at +3.2% against its baseline, at medium confidence across 16 contributing ingredients. You already watch your own invoices — this is the wholesale market underneath them, so a delivered-price jump can be checked against whether the market actually moved or your vendor did.
One honesty line before the numbers, because it changes how you read every one of them. Each ingredient's percentage here is its read against its own tracked baseline window — the gap, not a price. New: the dispatch now carries a permanent edition archive, so it can show the honest move since last week where the rulers match. The basket's data anchor has not refreshed since the prior edition (still 2026-05-01), so there is no new basket move to report — rather than invent one, I say so. The weekly panel underneath it did move, and the per-ingredient reads below are current. And every figure is a public wholesale level, never your delivered price: this is a read on the cost index, not a line for your food cost sheet. The point is direction and gap, not a number to paste into a cost sheet.

What's moving the basket
The basket is not one number — it is a weighted blend of 16 staples, so the headline +3.2% is really a tug-of-war. A heavy line barely moving anchors it: Chicken breast (boneless) is 17% of the basket, so it steadies the whole read. But the swing comes from elsewhere. This week Romaine lettuce, at just 5% of the basket but reading +111.4% against its baseline, adds about +5.6 pts — the pressure read is building, led by shipment volume on a 0–3 week lead, while Butter (AA, bulk) pulls back −0.6 pts (the pressure read is easing, led by cold-storage stocks on a 4–8 week lead). Here is the headline taken apart, so +3.2% is a story you can see rather than a figure to take on faith.
That is the honest shape of an index: a couple of volatile lines do most of the talking, and the steady staples keep it from whipping around. So read +3.2% as “Romaine lettuce pushing, Butter (AA, bulk) easing” — not as every shelf in the walk-in moving together. If the line doing the pushing is not one you carry, the basket may be louder than your own invoice this week.
What's flashing this week
The panel sorts into a short action list: 17 re-price signals, 3 on watch. A re-price flag means the move looks structural — elevated and sustained against the baseline. A watch flag means a real move that has not persisted long enough to act on yet. Neither is advice; both are calibrated, low-regret reads off the measured index.
- Re-price — Avocado. It reads +68.6% against its baseline — about $56.50/carton wholesale (range $53.25–$59.75); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Acorn squash. It reads +56.1% against its baseline — about $39.13/carton wholesale (range $35.75–$43.50); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Red leaf lettuce. It reads +45.9% against its baseline — about $39.13/carton wholesale (range $34.38–$51.75); elevated and sustained — the increase looks real. It has flagged 8 weeks running. This one is seasonal, so it eases when the season turns.
- Re-price — Cilantro. It reads +37.6% against its baseline — about $26.75/carton wholesale (range $25.38–$29.00); elevated and sustained — the increase looks real. It has flagged 6 weeks running.
- Re-price — Chicken thigh. It reads +31.5% against its baseline — about $1.42/lb wholesale (range $0.75–$2.29); elevated and sustained — the increase looks real. It has flagged 5 weeks running.
- Re-price — Collard greens. It reads +30.0% against its baseline — about $18.63/carton wholesale (range $16.81–$19.69); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Iceberg lettuce. It reads +28.2% against its baseline — about $57.50/carton wholesale (range $51.25–$63.75); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Lemon. It reads +24.7% against its baseline — about $48.00/carton wholesale (range $46.53–$49.63); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Parsley. It reads +18.5% against its baseline — about $31.50/carton wholesale (range $27.19–$32.56); elevated and sustained — the increase looks real. It has flagged 6 weeks running.
- Re-price — Cabbage. It reads +16.7% against its baseline — about $21.25/carton wholesale (range $19.97–$24.38); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Pears. It reads +13.0% against its baseline — about $40.25/carton wholesale (range $38.12–$42.94); elevated and sustained — the increase looks real. It has flagged 4 weeks running.
- Re-price — Ribeye. It reads +12.9% against its baseline — about $13.14/lb wholesale (range $12.61–$13.67); elevated and sustained — the increase looks real. It has flagged 4 weeks running.
- Re-price — Red potato. It reads +8.9% against its baseline — about $31.75/sack wholesale (range $29.75–$34.25); elevated and sustained — the increase looks real. It has flagged 6 weeks running.
- Re-price — Habanero pepper. It reads +5.8% against its baseline — about $37.63/carton wholesale (range $34.63–$41.31); elevated and sustained — the increase looks real. It has flagged 5 weeks running.
- Re-price — Artichoke. It reads +2.2% against its baseline — about $51.13/carton wholesale (range $47.00–$55.13); elevated and sustained — the increase looks real. It has flagged 8 weeks running.
- Re-price — Blueberries. It reads −4.2% against its baseline — about $30.38/carton wholesale (range $27.38–$33.50); reading well below baseline and holding — the move looks structural. It has flagged 5 weeks running.
- Re-price — Green beans. It reads −6.2% against its baseline — about $30.25/carton wholesale (range $27.75–$32.75); reading well below baseline and holding — the move looks structural. It has flagged 8 weeks running.
- Watch — Corn on the cob. It reads +39.7% against its baseline — about $28.00/carton wholesale (range $22.00–$32.50); a real move that has not persisted yet — watch the next read. It has flagged 2 weeks running.
- Watch — Cantaloupe. It reads +34.2% against its baseline — about $35.32/carton wholesale (range $27.00–$43.25); not enough history to tell a spike from a real trend — treat as real.
- Watch — Ground beef. It reads −2.3% against its baseline — about $5.51/lb wholesale (single-source); not enough history to tell a spike from a real trend — treat as real.
If nothing here matches a line on your own menu, that is fine — only act where the flashing item is something you actually buy. The whole panel is filtered to the index's shippable set, so every name above is an ingredient the hub can show a live reading for.
The widest gaps from baseline
Beyond the action flags, here is the full spread of movement. Reading above baseline this week: Avocado +68.6% · Acorn squash +56.1% · Red leaf lettuce +45.9% · Corn on the cob +39.7%. Reading below: Cauliflower −56.4% · Yellow squash −50.0% · Broccoli −48.8% · Serrano pepper −45.0%. The bars below scale to the largest mover so the gaps are legible — rust where cost is building, teal where it is easing.
Read these as gaps, not verdicts. A wide rust bar on a seasonal item often unwinds when the season turns; a wide teal bar can be a vendor clearing inventory rather than a durable easing. The bar tells you where to look; your delivered invoice tells you whether it reached your back door.
What's behind the moves
A percentage tells you what moved; it does not tell you why. The cost index carries a second, slower read for that — the pressure layer, which infers whether each staple is building or easing from the public lead indicators underneath it: feed grain and cattle-on-feed placements for proteins, cold-storage stocks for dairy, shipment volume and drought for produce, diesel for freight. It points a direction on a lead, never a price.
Where the panel's tracked staples sit this week, as of 2026-06-08:
- Ribeye — building, led by cattle-on-feed placements (16–26 week lead), moderate confidence.
- Beef tenderloin — building, led by cattle-on-feed placements (16–26 week lead), high confidence.
- Romaine lettuce — building, led by shipment volume (0–3 week lead), high confidence.
- Onions — building, led by shipment volume (0–3 week lead), high confidence.
- Cheddar cheese — building, led by cold-storage stocks (4–8 week lead), moderate confidence.
- Chicken breast (boneless) — easing, led by feed grain (corn) (6–9 week lead), high confidence.
- Whole chicken — easing, led by feed grain (corn) (6–9 week lead), high confidence.
- Pork loin — easing, led by market-hog supply (8–26 week lead), moderate confidence.
- Pork shoulder — easing, led by market-hog supply (8–26 week lead), moderate confidence.
- Tomatoes (round) — easing, led by shipment volume (0–3 week lead), moderate confidence.
- Russet potatoes — easing, led by shipment volume (0–3 week lead), moderate confidence.
- Butter (AA, bulk) — easing, led by cold-storage stocks (4–8 week lead), moderate confidence.

The feed market is the clearest of these chains. This week, Corn (feed) reads +10.4% against its baseline, and Soybeans (feed) reads +19.8% against its baseline, and Imported seafood reads +1.9% against its baseline — a feed read that flows through to the proteins it sits behind on a lag:
-
1
Corn (feed) reads +10.4%
A tracked feed input, read against its own baseline window this week.
-
2
It sits behind 7 proteins on the panel
Including Chicken breast (boneless), Whole chicken, Pork loin, Pork shoulder — the items whose cost the feed market helps set.
-
3
The read flows through on a lag
A building feed market is the context behind those proteins' own reads — directional, not a forecast.
Read the pressure layer like a forecast, not a thermometer: it tells you which way the wind is blowing on a multi-week lead, so a vendor quote moving the other way is worth a question. The dollar level above is today; this is the direction underneath it.
What's driving the flags
The flags above are measured reads; this layer adds the public, standing context behind clusters of them — what an item moves with, sourced and pitched as association, never a measured cause. A driver appears only where this week's read agrees with it, so the page never tells a supply-shock story over a number that is easing.
- Avian influenza (HPAI). Chicken thigh. Laying-flock and broiler losses from HPAI detections tighten egg and poultry supply — the standing context behind these reads, an association and not a measured cause of this week's prints.

Go deeper
This dispatch is the surface read. The layers underneath it are addressable, so an analyst — or an answer engine — can descend without the top read bloating:
- Per-ingredient pages — every flagged item has its own live page with the full reading and its sources, e.g. the Cost Index hub.
- This edition as data — week-2026-06-18.json and .csv: the frozen per-ingredient snapshot behind this page.
- The full series & feed — feed.json (machine catalog) and the edition archive (every week).
- Methodology & confidence — the versioned methodology (v1.3.0), including why nothing here is rated high (that needs two independent dollar sources) and the published band-coverage backtest.
How to read this, and what it is not
Three rules keep this honest. First, every number is a public wholesale level, never your delivered price — freight, contract, and pack size all sit between this panel and your invoice. Second, each percentage is a read versus that ingredient's own tracked baseline window, a state-of-play snapshot of what is flashing; where this dispatch reports a move since last edition, it says so explicitly and only where the basket's ruler has not changed. Third, the panel is drawn from public USDA, BLS, and FRED data; when an input cannot earn a credible reading, it stays off the page rather than showing you a guess. Watch your own delivered invoices against these reads — the gap between the two is where a vendor conversation lives, and it is the first place a moving prime cost shows up.
