Outgoing IMF Chief Economist Warns: Fragile Ceasefire, Trade Reshaping, and Long-Term Sanctions Ineffectiveness
Claire Weston
Outgoing IMF chief economist Pierre-Olivier Gourinchas warned that the U.S.–Iran ceasefire is extremely fragile, with strategic petroleum reserves largely depleted — leaving the global economy far less cushioned if conflict reignites, even as trade deals increasingly bypass America.
Why is the ceasefire "fragile" enough for the IMF's top economist to flag it?
Gourinchas noted that rapid reserve releases and refinery adjustments kept actual oil removal to about 3% of global supply — far below the initially feared 10%–15%.
This means → the last shock was contained by burning through reserves, not because supply held up on its own.
He warned that reserves are now severely depleted. If the ceasefire collapses and supply tightens again, countries will have far fewer tools to cushion the blow.
On the same day, Trump accused Iran of attacking a vessel near Oman, calling it a ceasefire violation. In plain terms = the deal is signed, but either side could walk away at any moment — and the fallout this time would be harder to contain.
How is global trade rerouting around the United States?
Gourinchas pointed to the EU completing trade deals with Latin America and India in under a year, stressing it was "no coincidence."
His words: "You cannot not deepen trade relationships with other countries."
This means → Trump's tariff policy is driving a clear outcome: other economies are grouping together, and most new trade agreements exclude the U.S.
This reflects a deeper signal — tariffs are not just a cost imposed on others; they are also pushing America out of the emerging trade network.
Do sanctions actually work? What does the IMF's chief economist think?
Gourinchas was blunt: tariffs and sanctions do carry short-term leverage, but targets do not sit still.
Sanctioned parties quickly find workarounds, accelerate domestic innovation, and cultivate new trading partners.
His conclusion: "Over the medium to long term, these tools have almost never worked."
In plain terms = sanctions are a strong drug — they hurt in the short run, but the target builds resistance fast, and the effect eventually drops to zero.
What will IMF's July 8 forecast say?
Gourinchas revealed that the IMF will release a new round of global economic projections on July 8 — by which time he will have returned to teaching at UC Berkeley.
He hinted the Fund may move from April's three-scenario framework back to a single baseline forecast, but disclosed no figures.
He explained that 2025 and 2026 lack historical precedent, forcing economists to "stay humble" — but scenario ranges should not become the norm.
Last month, spokesperson Julie Kozack said the global economy was sliding from the 3.1% reference forecast toward the 2.5% adverse scenario. The July 8 release will be the key checkpoint for whether that judgment has shifted.
