The rollercoaster ride of US tariff policy has dominated the headlines and airwaves in the last few weeks.
The US president announced taxes on goods imported into the US from around the world, then rowed back or delayed many, but doubled down on Chinese imports.
Some countries have hit back with tariffs of their own; others - such as the UK - are trying to negotiate.
We are in relatively unknown territory in modern economics and the picture seems to change almost every day, so predictions have to be taken with a large dose of salt.
In theory, when tariffs are announced, and retaliation comes, then higher taxes all round will make goods more expensive for consumers.
But, particularly for the UK, things are far more nuanced. The 10% tariff on UK goods imported by the US is lower than feared, and retaliation looks unlikely.
Indeed, there are heightened expectations of a UK-US trade deal, rather than a trade war.
So, any price rises would be limited.
China is facing massive 145% tariffs on all its goods bound for the US. If that puts up barriers to the US market, it may find other places to sell its - often cheaply manufactured - products, such as the UK.
A so-called dumping of cheap Chinese products in the UK will increase price competition and could slow the rate of inflation.
