Gold exports are usually not really "exports"Gold. We exported gold to get us there on that list. Is gold a natural resource in UK? Corrected for inflation, 'goods' exports have not increased since 2016.
Some gold hidden away in the vaults of the Bank Of England stays in the same rack, but is labelled in the books "property of Elon Musk" or whoever has bought it. It subsequently stays in the same racks when he sells it. It might belong to Barclays Bank tomorrow and Fidelity the day after.
It might have been in the same rack for 50 or 100 years and changed ownership numerous times.
For this reason gold "exports" and "imports" are often noted as excluded from import/export figures. At times the values of transactions can be so high that they temporarily overwhelm real export and import values but are not part of any real export and import trends.
