TL;DR
The BIS chief warns that fiscal policy measures responding to the Iran conflict could exacerbate inflationary pressures globally. Central banks should be ready to act if needed, he says.
The General Manager of the Bank for International Settlements, Pablo Hernandez de Cos, warned on May 11, 2026, that fiscal policy responses to the ongoing Iran conflict could worsen inflation worldwide. He emphasized the need for central banks to be prepared to act if inflationary pressures escalate further.
Hernandez de Cos stated that the geopolitical tensions in the Middle East, particularly the Iran conflict, are expected to drive inflation upward and slow economic growth. He expressed concern that excessive fiscal measures aimed at countering the conflict’s economic impacts could intensify inflationary pressures. The BIS chief highlighted that central banks should remain vigilant and ready to implement monetary policy adjustments if inflation begins to accelerate beyond target levels. The warning comes amid ongoing debates among policymakers about how to respond to the economic fallout from the conflict, which has already disrupted global energy markets and supply chains.
Why It Matters
This warning underscores the delicate balance policymakers face in responding to geopolitical crises without fueling inflation further. The potential for fiscal expansion to exacerbate inflationary pressures could complicate efforts by central banks worldwide, especially as many are still managing the aftermath of recent inflation surges. The advice from the BIS chief highlights the importance of cautious fiscal responses and vigilant monetary policy to maintain economic stability amid geopolitical tensions that threaten to destabilize global markets.

Background
The Iran conflict has intensified in recent weeks, raising fears of broader regional instability and disruptions to global energy supplies. Central banks, including the Federal Reserve and the European Central Bank, have been gradually tightening monetary policy to combat inflation, but the current geopolitical situation adds new risks. The BIS has previously warned of the inflationary impact of geopolitical shocks, and Hernandez de Cos’s latest remarks reinforce that stance. Historically, conflicts in the Middle East have led to spikes in oil prices and inflation, prompting cautious policy considerations worldwide.

The BIS chief warns that aggressive fiscal measures could intensify inflation, making it harder for central banks to control prices and maintain economic stability amid geopolitical tensions.
How might central banks respond to rising inflation caused by these risks?
