Key Takeaways
- • BIS General Manager Pablo Hernandez de Cos warns that broad-based, persistent fiscal stimulus risks triggering inflation and forcing central banks to raise interest rates, advocating instead for targeted, temporary spending measures.
- • Prolonged Middle East conflict poses dual financial stability risks: rising public debt is increasingly intermediated by nonbank financial institutions and highly leveraged hedge funds, creating systemic vulnerabilities if geopolitical tensions persist.
- • Market sentiment driven by AI optimism and expectations of rapid Middle East conflict resolution creates vulnerability to "abrupt market corrections" if these expectations fail to materialize, according to the BIS chief.
- • Central banks should selectively "look through" temporary negative supply shocks from energy disruptions only if they do not destabilize inflation expectations or trigger harmful second-round wage and pricing effects.
- • Countries including Japan have responded to Middle East volatility by ramping up fiscal spending to offset surging oil prices, creating tension between growth support and inflation control for monetary policymakers.
Summary
The Bank for International Settlements is calling for fiscal discipline as geopolitical tensions and market optimism create competing inflationary pressures across major economies. In an interview with Japan's Nikkei newspaper published May 11, BIS General Manager Pablo Hernandez de Cos emphasized that governments must maintain targeted and temporary fiscal spending rather than deploying broad-based, persistent stimulus that could elevate inflationary risks and necessitate higher interest rates from central banks.
The BIS chief flagged two concurrent macro risks. First, prolonged Middle East disruptions threaten global financial stability, particularly given the structural shift in how public debt is now intermediated. Over the past 15 years, rising public debt increasingly flows through nonbank financial institutions and highly leveraged hedge funds rather than traditional banking channels, amplifying systemic fragility. Second, current market sentiment is buoyant but fragile, driven by optimism around artificial intelligence developments and market expectations of rapid Middle East conflict resolution. De Cos cautioned that "if these expectations prove wrong, I can easily see the potential for abrupt market corrections."
The Middle East conflict has already prompted fiscal responses. Countries including Japan have increased government spending to cushion economic damage from surging oil prices, creating a policy dilemma for central banks that face simultaneous pressure to raise rates to combat inflation risks even as growth cools. De Cos outlined a nuanced approach: central banks should selectively "look through" temporary negative supply shocks if they do not destabilize inflation expectations or trigger harmful second-round effects such as wage-price spirals. This guidance suggests the BIS sees merit in central banks maintaining policy patience on certain energy-driven inflation, provided inflation expectations remain anchored and wage pressures remain contained.
The commentary reflects heightened macro policy tensions in 2026, where geopolitical shocks, technological optimism, and structural changes in financial intermediation are creating cross-currents for both fiscal and monetary authorities.
