The global economy entered 2025 expecting tariffs to cause a major slowdown. Six months later, the damage is more complicated.
Businesses have not simply stopped trading. They have changed when and where they trade.
The IMF's latest July update later showed why this distinction matters: it raised its 2025 global growth forecast to 3.0%, up from its April projection, partly because companies brought imports forward before higher tariffs took effect.
That sounds like good news.
It is not necessarily.
Imagine an American company knows tariffs on an imported component are likely to rise in August. It has an incentive to import six months of inventory in July.
GDP rises because imports surge and companies accumulate stocks.
But the underlying demand for the product has not necessarily changed.
This is called front-loading.
It can make economic data look stronger before tariffs take effect while creating weaker activity later.
That is one reason the global economy in 2025 cannot be judged simply by looking at headline GDP growth.
Trade policy is changing the timing of economic activity.
There is another adjustment happening.
Companies are diversifying supply chains.
A manufacturer that previously sourced 90% of a component from one country may now decide that paying slightly more for suppliers elsewhere is worthwhile if it reduces the risk of sudden tariff increases.
That creates a strange economic trade-off.
Diversification can make supply chains more resilient, but resilience costs money.
A company may deliberately choose a more expensive supplier because certainty has become more valuable than the lowest possible production cost.
That could mean a structurally more expensive global trading system.
The IMF's July forecast still warned that tariffs, geopolitical tensions and fiscal pressures remained major risks.
The lesson is therefore not that tariffs have failed to damage the economy.
It is that businesses are adapting faster than the headline numbers suggest.
The next question is what happens when the stockpiled inventories run down. If imports fall sharply later in the year, the apparent resilience of global growth could prove to have been partly borrowed from the future.
