POSCO Announces Sharp Stainless Steel Price Hikes for April 2026 Amid Surging Input Costs

SEOUL, South Korea — POSCO, one of the world’s leading stainless steel manufacturers, has officially announced a significant price increase for its April 2026 shipments. Effective April 16, 2026, the hike addresses a convergence of mounting cost pressures that have heavily impacted the mill’s margins throughout the first quarter of the year.

Strategic Price Adjustments: 300 & 400 Series

Following a challenging Q1, POSCO has moved to raise list prices across its primary stainless steel product lines. The adjustments reflect a broader industry trend where producers are shifting toward more aggressive pricing to restore profitability.

• 300-Series Products: Prices for the 300-series (including standard 304 grades) will increase by at least KRW 100,000/tonne (~$72/t).

• 400-Series Products: Prices for the ferritic 400-series have also been adjusted upward by approximately KRW 100,000/tonne, driven by rising ferrochrome and energy expenses.

Core Drivers: Why Prices Are Climbing

Industry analysts highlight three critical “macro-economic pillars” that forced POSCO’s hand this month:

1. Surging Raw Material & Energy Costs

The cost of nickel, ferrochrome, and coking coal has remained volatile. Recent disruptions in global supply chains—exacerbated by ongoing tensions in the Middle East—have driven oil and logistics costs to unsustainable levels. For POSCO, which operates major works in Pohang and Gwangyang, the rising cost of industrial electricity and natural gas has added further strain to production overheads.

2. Currency Devaluation & Exchange Rates

The South Korean Won (KRW) has seen significant depreciation against the U.S. Dollar in recent weeks. Since raw materials like nickel ore and scrap are primarily traded in USD, the weak local currency has effectively spiked the “landed cost” of essential inputs, leaving the mill with zero flexibility to absorb further losses.

3. Inventory Drawdown & Market Leverage

Evidence shows that global steel inventories at major industrial enterprises fell by 7.6% in late March. With distributors’ “stock-on-hand” reaching multi-month lows, POSCO and other major Asian mills (like Yusco in Taiwan) now have the necessary market leverage to implement these hikes without dampening immediate demand.

Market Outlook: A Ripple Effect Across the Supply Chain

The POSCO hike is expected to trigger a ripple effect across the South Korean and wider Asian markets. Domestic competitors and downstream industries—including automotive, construction, and home appliance manufacturers—are already bracing for higher procurement costs in Q2.
