✍️ Kalshi's March CPI market just spiked to 0.8% -- and it's not hard to see why

THE CPI BET JUST WENT VERTICAL

GM. This is flowframe, the only newsletter that watches CPI futures the way your mechanic watches that "check engine" light -- knowing something expensive is about to happen.

Two weeks ago, Kalshi's "CPI in March" market was sitting around 0.3%.

Today? The forecast is 0.8%. Up 0.5 percentage points in less than three weeks.

That's a huge jump.

Look at that chart. Flat, flat, flat through most of February. Then around February 28 -- the day the Iran war started -- the line rips straight up and doesn't come back down.

Bettors are now pricing a 78% chance that March CPI comes in above 0.6% month-over-month. A 56% chance it tops 0.7%. And a 38% chance it blows past 0.8%.

For context: February's CPI print was 0.3%. The one before that was 0.2%. A 0.8% monthly reading would be the hottest since 2022.

"But wait, what happened on February 28th?" -- you, probably.

That's when the U.S. and Israel struck Iran. And everything changed.

Here's the chain reaction 👇

1. Oil went nuclear.

Brent crude went from about $70 a barrel before the war to $119.50 at its peak. It's settled around $90-100 now, but that's still 30-40% higher than a month ago. The Strait of Hormuz, which handles roughly 20% of the world's oil supply, is essentially shut down.

This is the largest oil supply disruption in history. Not an exaggeration. Production from Kuwait, Iraq, Saudi Arabia, and the UAE dropped by at least 10 million barrels per day as of March 12.

2. Gas prices followed. Kalshi noticed.

The national average hit $3.58 per gallon this week, up from about $3.00 before the war. That's a 20% jump in two weeks. In California, prices blew past $5 a gallon.

Kalshi's gas price market is pricing a 60% chance that the U.S. average exceeds $4.00 this month. Three weeks ago that would have been a joke bet. Now it's the favorite outcome.

Gas is the single most visible price in the economy. When it moves this fast, people feel it immediately. And the BLS counts it.

3. It's not just gas.

Brian Bethune, an economics professor at Boston College, told CNN: if higher oil prices persist, "you're going to see a persistent cost shock." Airlines are already raising fares after jet fuel spiked. Fertilizer prices are climbing because the Strait is a major shipping route for agricultural inputs. Food prices were already up 3.1% year-over-year in February, and that was before the war.

Sonu Varghese, chief macro strategist at the Carson Group, called February's CPI number "the calm before the storm."

WHY THIS NUMBER DECIDES WHAT HAPPENS NEXT

"Ok, inflation goes up. Bad for groceries. But why should I care beyond the gas pump?"

Because this number decides what the Fed does. And the Fed decides where markets go.

Here's the situation. The Fed cut rates by 1.75 percentage points over the last cycle. Markets were pricing in at least one more cut by September. But if March CPI prints at 0.8%, more than double what we saw in January, that changes everything.

Kalshi's Fed market has a 98%+ chance they hold rates at 3.5%-3.75% next Wednesday. That's as close to locked as it gets. But the real question isn't March. It's what comes after.

If oil stays above $100 and CPI keeps running hot, the Fed is stuck. Cut rates and inflation spirals. Hike rates and you crush an economy already absorbing tariffs and war costs. Neither option is good.

And the economy is already wobbling. Kalshi's recession market jumped above 34% this week, its highest since November, after oil topped $100. Late last week it was under 25%. That's a 9-point move in days. Unemployment is at a four-year high of 4.6%.

So you've got inflation spiking, recession odds rising, and the Fed pinned to the floor. That combination has a name: stagflation. And it's the one word that makes every portfolio manager reach for the Pepto-Bismol.

The S&P 500 is down about 1% since the war started. Treasury yields spiked after the February CPI report, even though the number came in exactly as expected. Traders weren't looking at February. They were looking ahead to March.

Deutsche Bank analysts wrote in a March 10 note that higher energy prices could "lead to higher headline inflation" in the months ahead, and called the path toward disinflation "murkier."

Mark Zandi, chief economist at Moody's, put it this way after the February report: "I don't get any sense that inflation is decelerating. It feels like it's uncomfortably and persistently high."

And that was before a single day of war-driven gas prices showed up in the data.

The Takeaway:

The March CPI number drops April 10. That's 27 days from now. The Kalshi market is telling you to brace for a hot one.

If it comes in at 0.8% or higher, the 2.4% annual inflation rate we saw in February is about to look like a relic. CNBC cited analysts estimating inflation could hit 3.5% by year-end if oil averages $100 for the rest of the year.

Here's the Kalshi scoreboard right now:

- March CPI above 0.6%: 78% chance - Gas above $4/gallon this month: 60% chance - Fed holds rates next week: 98% chance - U.S. recession in 2026: 34% chance

Every one of those numbers was lower two weeks ago. Every single one. The market is pricing in pain across the board.

Watch the oil price, the gas pump, and Jay Powell's press conference next Wednesday. The Fed decision itself is a foregone conclusion (they hold). But Powell's words matter. If he even hints at the possibility of rate hikes, expect stocks to sell off hard. If he stays dovish, markets breathe. Either way, April 10 is the real test.
