Stiglitz Warns U.S. Could Face Stagflation Amid Tariffs and Geopolitical Tensions
Nobel laureate economist Joseph Stiglitz of Columbia University warned that the United States could face a period of stagflation—a combination of high inflation and slow growth—as tensions in the Middle East and tariff policies weigh on the economy. He spoke in a Money Matters podcast interview that was released recently.
Stiglitz said price increases are being driven first by tariffs and now by broader geopolitical tensions, while economic growth has slowed. He argued that the U.S. economy has relied on AI as a short-term engine rather than building a healthy, diversified foundation for long-term prosperity.
He cautioned that the United States could confront multiple macro shocks, including shocks to the stock market, oil markets, and food prices, in addition to tariff-related pressures. Taken together, he said, these forces could push the economy into a difficult period.
On energy, Stiglitz noted that the United States being a net exporter of oil does not shield the economy from higher international crude prices. He suggested that while the energy sector might benefit from rising prices, the prospect of broader gains being passed to consumers was unlikely.
The economist drew a historical parallel to the 1970s oil shocks, describing them as a major disruption that caused a long global downturn before the world economy recovered. He used the analogy to stress the potential severity and duration of today’s risks.
Regarding artificial intelligence, Stiglitz argued that firms pursuing a few “final winners” have encouraged over-investment and that a malfunctioning macroeconomy could prevent AI firms from delivering large profits. He warned there could be an AI bubble, with a burst potentially producing significant macroeconomic consequences.
For U.S. readers, the implications extend to inflation expectations, monetary policy, energy markets, and technology investment. The concerns highlight how overseas geopolitics and commodity prices can spill over into American markets, supply chains, and financial stability, underscoring the need for balanced growth and resilient macro policy.

The discussion was featured in a Korean media outlet’s coverage of his remarks on an international podcast, reflecting ongoing global interest in how U.S. policy, energy dynamics, and AI development intersect with macroeconomic risk.
