Proposal to launch Mexican steel HRC index, rebar price assessment, delivered Bajío

Fastmarkets proposes to launch a Mexican steel hot-rolled coil index and a price assessment for Mexican rebar, both delivered in Bajío, following ample feedback from the market suggesting we could provide additional clarity to the Mexican steel market with prices focused on the central region.

The central Mexican market, or the Bajío region, is a main hub for steel market activity in Mexico because of its proximity to ports on the Atlantic and Pacific coasts and because of the many participants in the region (one blast furnace, 12 electric-arc furnaces, four rolling mills and over 10 big traders). This market encompasses producers, distributors, service centers and many end-use consumers.

This price launch will enable the coverage of the Mexican market to be broadened, along with further adding to the suite of prices Fastmarkets has in Latin America. The new Bajío prices will add a reference point for Mexican market participants, separate from the influence of the US.

The specifications for the proposed index and assessment are as follows:

Steel hot-rolled coil index, delivered Bajío, Mexico, peso/tonne
Quality: 
SAE 1006-1008 commercial steel and corresponding grades, 48 inches wide, caliber 8-14
Quantity: Min 35 tonnes
Location: Mexico, Bajío region, delivered price
Timing: 4-8 weeks
Unit: Mexican peso/tonne
Publication: weekly, Thursday, 2-3pm ET
Notes: Standard packaging, raw materials surcharges included. Payment terms are typical commercial practice in the HRC market. Transactions that are conducted on different payment or credit terms will be adjusted back to the base specifications, taking into account discounts and standard commercial terms.

Steel reinforcing bar (rebar), delivered Bajío, Mexico, peso/tonne
Quality: 
Grade 42, diameter: 9.5-15.9 mm, length: 12,000 mm, NMX-B-506 and equivalent
Quantity: Min 35 tonnes

Unit: Mexican peso/tonne
Publication: weekly, Thursday, 2-3pm ET

These prices will be part of the Fastmarkets steel package.

The consultation period for this proposed launch starts from Tuesday September 30, 2025, and will end on November 4, 2025. The launch will take place, subject to market feedback, on November 6, 2025.

Fastmarkets’ index methodology screens outliers and applies a quantity-weighted model to ensure that the steel hot-rolled coil index, delivered Bajío is the most robust in the industry. Fastmarkets has no financial interest in the level or direction of the index.
