Fuel, shipping capacity, surcharges and currency move in the market months before they reach an invoice. sirius measures that pressure every Friday across the ten corridors most of the world's freight moves through, and tells you what to do about it.
Simulation · Strait of Hormuz disruption
Close one strait and the cost of it arrives somewhere that has never shipped through it.
Published weekly by
Only part of a freight bill moves with the market. The rest is a rate you agreed months ago. sirius tracks the part that moves, and how long it takes to arrive.
Fuel jumps, a chokepoint closes, carriers pull capacity, a currency slides. It happens in public, and it happens first.
Nothing changes on your bill yet. How long you wait depends on how you buy: spot in about thirty days, an annual contract in ninety.
By the time it shows up, the market event is two to three months old and the budget conversation has already happened.
What a reading is not
A reading of 134 does not mean your freight bill is up 34 percent. Your base rate is contractually fixed. Only the variable part moves, and depending on how the freight travels that is between 25 and 70 percent of the bill.
What a reading is
January 2026 sits at 100. A lane at 208 means the inputs to that corridor have roughly doubled since then. It tells you what is coming, and roughly when.
Every reading is built from the same four pressures, measured separately so a lane can say which one is carrying it. Fuel and capacity behave differently from surcharges and currency, and a carrier conversation goes differently depending on which is moving.

Read off the ten readings above, and rewritten every Friday. Nothing here is written in advance.
Under most pressure
Middle East → Far East is the heaviest lane on the board at 339.3, and surcharges is what is carrying it.
Moved most this week
North America domestic fell 2.1 percent against last week, the largest move on the board.
Already on its way
On the heaviest lane, 62 percent of this pressure has reached spot rates, 86 percent short term contracts and 98 percent annual ones. The rest is still in transit to your invoice.
Some readings were revised after Friday as later data arrived. The board always shows the current reading.
02Week 40The report for this week
The board above is what the market did this week. The report is what to do about it: where costs are heading over the next eight weeks, which lanes are worth moving on, and the same week rewritten for the job of the person reading it.

Past crisesFreight costs go up faster than they come down, and they reach your invoice long after the market has moved. Those two facts are why a weekly reading is worth having at all.
A shock takes weeks to arrive and months to clear. The buyer who locks on the way up pays for the whole descent.
How you buy decides when you feel it. The same market week lands on three different invoices, weeks apart.

The index, in one sentence
sirius is TetriXX AI's weekly freight cost pressure index: 300+ market signals across 10 global trade lanes, combined into one reading per lane across fuel, capacity, surcharges and currency, and published every Friday.
Earlier material calls the same index the freya Cost Pressure Index (FCPI).
A sirius reading of 118 means the cost pressure inputs on a lane are running 18% above the January 2026 baseline, which is not the same as a freight bill 18% higher. This article explains what that number means in practice, what drives it, and how to act on it.
By the time your CFO sees a freight cost spike on the P&L, the market event that caused it is already 30-90 days old. sirius shows you what is coming - before it arrives in your invoices.
How you buy your freight decides when a market move reaches your bill: about 30 days at spot, 60 on a 6 to 12 month contract, 90 on an annual one.
When sirius detects a pattern that resembles a past crisis, it surfaces the match with a confidence score and the trajectory from the previous event. Here is what that output looks like in practice - and how the best-matching analog shapes the forward projection scenarios.

A freight cost outlook is not a forecast. It is a structured view of the pressure signals that will drive your freight costs over the next 1 to 12 months. Here is how to build one that holds up in a board review.
