How Today’s Energy Crisis Compares to Past Shocks
As of April 17, 2026, senior Irish government officials have described the current global energy crisis as “the worst the world has ever seen” and “the biggest energy shock in history.” Though, energy experts consulted by RTÉ Clarity note that this assessment depends on how the crisis is measured.
The current crisis has been driven by escalating conflict in the Middle East, particularly disruption to energy infrastructure and key shipping routes like the Strait of Hormuz, through which a significant share of the world’s oil passes. This has caused unprecedented levels of supply disruption globally.
Although supply chain interruptions are at historic highs, experts say the economic impacts—such as price increases and broader economic strain—have not yet surpassed those of past shocks like the 1970s oil embargoes. According to RTÉ Clarity’s analysis published on April 17, 2026, the current crisis, though severe in terms of supply disruption, has not exceeded the economic consequences of those earlier events.
The International Energy Agency’s Executive Director, Dr Fatih Birol, has characterized the situation as “the greatest threat to global energy security in history,” underscoring concerns about long-term vulnerabilities in global energy systems despite current economic impacts remaining below those of previous major shocks.
