Domestic rebar demand has declined for several years amid a prolonged construction slump, and, per one industry tally, this year's rebar demand is estimated at 6.59 million tons for the first half, the lowest for a third consecutive year.
Eugene Investment & Securities noted in a May 2026 report that domestic rebar demand has declined since 2021 due to the construction downturn, and the industry's average utilization rate plunged from 82% in 2021 to 50% in 2025, resulting in structural oversupply with roughly 5 million tons of idle capacity.
To offset this domestic shortfall, Korean rebar makers have ramped up exports, and Korean rebar exports to the US surged from 90,000 tons for all of last year to 270,000 tons in the first quarter of this year.
The same report projected that 2026 Korean rebar exports to the US would reach 800,000 tons, equal to 8% of US rebar demand. Driven by export growth, domestic rebar industry utilization improved to 61% in January-April 2026, up 11 percentage points year-on-year, easing the per-ton fixed-cost burden.
Even so, rising steel scrap costs meant the three major dedicated rebar makers - Daehan Steel, Korea Steel, and Hwanyoung Steel Industries - remained in the red in the first half of 2026.
Meanwhile, China's production cuts have been easing global steel oversupply, creating a favorable external environment for Korea's steel industry.
The government's 2026 SOC budget was set at KRW 27.5tn, up KRW 2tn (7.9%) year-on-year, providing some support to public-sector demand, but the 'K-shaped' divergence in private-sector activity suggests regional gaps between the Seoul metro area and other regions could widen for rebar and other major steel products as well.
