Iron Market on September 9, 2026; Continued Pressure from Steel Billet on Rebar Prices
The iron and steel market on September 9, 2026 entered today’s trading session under conditions where steel billet prices, supply levels on the Iran Mercantile Exchange, and rebar buyers’ behavior have become the key variables shaping the market.
In the first weeks of September, price increases began at the early stages of the steel supply chain and gradually became visible in the billet, rebar, and other steel product markets.
An analysis of trading activity during the second week of September shows that sponge iron prices increased by approximately 3.1%, steel billet prices by around 2%, and rebar prices by nearly 6%.
These figures indicate that the Iranian steel market remains under pressure from rising raw-material costs, while rolling mills are facing higher prices when sourcing billets.
Meanwhile, billet trading data shows that approximately 127,000 tons of Bloom billet were offered on the Iran Mercantile Exchange between September 8 and 10, with demand reaching nearly twice the offered volume.
In these transactions, the weighted average price of steel billet reached approximately 667 million tomans per ton, representing an increase of around 3.6% compared with the previous week.
The rise in steel billet prices is highly significant for the market, as billets are the primary raw material for many rebar manufacturers, and higher billet prices can increase the production costs of steel products.
In today’s market, the prices of many types of construction rebar also remain at elevated levels, with price differences between manufacturers based on brand, size, standard, and loading location.
Some market price lists for September 9 show opening rebar prices from major producers at more than 80,000 tomans per kilogram.
However, today’s key issue is not only rebar prices in the open market; the Iran Mercantile Exchange has once again become one of the main indicators of the market’s direction.
According to today’s supply information for September 9, Sirjan Jahan Steel offered several A3 rebar baskets in different sizes in the industrial trading hall of the Iran Mercantile Exchange.
These offers included rebar in sizes 14–20 and 22–32, and buyers’ response to these offerings could provide an important signal for the long steel products market in the coming days.
Under these conditions, the gap between billet and rebar prices has become increasingly important for rolling mills, as a rapid increase in billet prices without a corresponding rise in finished-product prices could reduce rebar producers’ profit margins.
At the same time, the market continues to face a significant challenge on the consumption side; rising prices do not necessarily indicate increased real consumption in the construction and infrastructure sectors.
Trading activity during the second week of September also indicates that the upward trend has not been uniform across all steel products, with some segments continuing to face weak demand.
Therefore, the current market can be viewed as one in which production-cost pressures on one side and limited real demand on the other are shaping the direction of prices.
If steel billet prices remain elevated in upcoming Iran Mercantile Exchange transactions, upward pressure on rebar, I-beam, and other steel products may continue.
Conversely, continued stagnation in the construction sector and reduced purchasing power could prevent production-cost increases from being fully reflected in final product prices.
The exchange rate also remains an important variable in the iron and steel market, as fluctuations affect inventory replacement costs, sellers’ expectations, and manufacturers’ decisions regarding domestic sales or exports.
As a result, market participants should closely monitor four factors in the coming days: steel billet prices, Iran Mercantile Exchange transactions, the exchange rate, and actual rebar demand.
Overall, Iran’s iron and steel market in mid-September 2026 has entered a sensitive period. Rising raw-material prices are supporting an upward trend, while weak consumer demand remains a significant obstacle to a broad-based price surge.
For rebar buyers and construction-industry participants, monitoring today’s rebar prices, steel billet prices, and the latest Iran Mercantile Exchange transactions can play an important role in determining the appropriate timing for purchases.
