Analysis based on tariff announcements up to September 1, 2025

The following charts only include projections based on US tariffs. They do not include retaliation by other countries/regions. They do not include country risk adjustments.

The results are presented as deviations from a baseline that has no increases in tariffs by any of the regions.

The shocks used for the high and low US tariff scenarios are documented in the following charts:
