Q1 2026 Market Updates

Geopolitical Impact of Iran, US, and Israel War on the South Korea HVAC Market

United States: The South Korea HVAC Market, a key segment of the global economy, is experiencing a complex operating environment in Q1 2026 as a direct consequence of the US-Israel-Iran war. South Korea imports over 80% of its oil from the Middle East, making it among the most structurally exposed Asian economies to the Strait of Hormuz closure. The government released strategic reserves to cushion the shock. Qatar provides a significant share of South Korea's LNG imports. QatarEnergy's force majeure has created acute LNG supply uncertainty, pushing electricity costs higher for industrial and commercial users. Rising industrial energy costs are filtering through to all manufacturing and consumer sectors in South Korea, while the government's emergency reserve release provides partial but temporary buffer.

Iran: Iran's domestic South Korea HVAC sector has been effectively suspended by the conflict. US-Israeli strikes on industrial and civilian infrastructure across Tehran, Mashhad, Isfahan, and other major cities have disrupted all commercial activity. Power outages from attacks on electricity generation facilities have halted manufacturing operations, and the collapse of the commercial banking and logistics system has eliminated any residual trade flows. The broader humanitarian crisis, with over 1,900 casualties and 4,000+ civilian buildings damaged, has redirected the entire Iranian economy toward survival rather than production or consumption.

Israel: Israel's South Korea HVAC sector is experiencing near-term disruption from wartime conditions. Consumer spending on non-essential categories has declined as millions of Israelis regularly shelter from missile and drone alerts. Supply chain logistics are disrupted by regional airspace closures, elevated war-risk insurance premiums, and the suspension of major carrier services through the region. International business partnerships with Israeli companies have been temporarily suspended. Post-conflict reconstruction and recovery demand is expected to provide meaningful demand acceleration across affected market segments once operational conditions normalise.

Key Takeaways

Government

• South Korean infrastructure agencies should revise capital project cost estimates upward by 20-30% to account for steel surcharges, bitumen inflation, and elevated energy costs, preventing budget overruns from invalidating project approvals.
• Governments should consider temporary import duty relief for critical construction materials including structural steel and aluminium, partially offsetting European and Asian surcharges of up to 30% that are inflating project costs.
• Public-private partnership frameworks should incorporate conflict-related force majeure and cost escalation provisions that allow project developers to manage unprecedented input cost volatility without contract termination.

Market

• The combination of 30% steel surcharges, 25-40% bitumen/asphalt price increases, and 40% diesel cost inflation represents the most severe simultaneous construction input cost shock in recent history, requiring mandatory project cost estimate revisions.
• Gulf construction activity has effectively halted with NEOM contracts cancelled and FDI down 60-70%, temporarily removing a significant source of global demand for construction materials and equipment from the market.
• Post-conflict reconstruction across Iran, Israel, Lebanon, and Gulf states will generate substantial demand for construction materials and services, creating a medium-term demand pipeline that partially offsets the near-term market disruption.

Procurement

• Construction procurement managers should lock in structural steel and aluminium supply contracts at current pricing before further conflict-driven surcharges are implemented by European and Asian steel mills facing elevated energy costs.
• Project developers should build contingency reserves of 25-30% into construction tender estimates for petroleum-derived materials including bitumen, sealants, coatings, and plastic pipe systems that are all experiencing 20-40% cost inflation.
• Procurement teams should evaluate domestic sourcing alternatives for construction inputs where available, as locally produced materials are less exposed to the freight cost surcharges and war-risk insurance premiums affecting imported goods.
