## Prediction

Over the coming week, the unfolding retaliatory tariff conflict flagged by PM Carney will likely lead to a discernible downgrade in UK growth expectations and mild but persistent downward pressure on GBP. Markets will start to price in lower export volumes, higher import costs, and an adverse terms-of-trade shock, especially if tariffs hit automotive, agriculture, or steel. This will complicate Bank of England policy by mixing imported inflation with falling real incomes, raising the risk of policy missteps. Confirmation would be analyst forecast revisions, widening UK CDS spreads, and weaker sterling vs USD and EUR; denial would be rapid de-escalation of the tariff dispute or narrow, symbolic measures with minimal economic footprint.

## Drivers

- National address by PM Carney explicitly warning of 'tough times ahead' from retaliatory tariffs
- Trend: Western economic blocs weaponizing tariffs and trade rules as strategic tools
- Existing Brexit-related sensitivity of UK trade flows
- Heightened geopolitical tensions making trade disputes more politically salient
