What happens if a basic income were adjusted for those price increases? One would think it would be linked to CPI and living costs.

I'd expect people to buy (more) imported products rather than (the same amount of more expensive) domestic products.

It would probably be worthwhile to give people part money and part vouchers for certain eligible (i.e. domestic but some international treaties might not allow this discrimination of imported goods) products, in order to keep the purchases of domestic goods at a high level.
