Physical premiums with tax-wedge decomposition
Physical premiums with tax-wedge decomposition: for each venue (Shanghai/Tokyo/India/London) the gross premium over COMEX, the embedded import-duty/VAT/consumption-tax wedge, and the ex-tax 'market' premium — the real physical-demand signal after stripping tax distortion. Optional ?metal=gold|silver|platinum|palladium.
