When a Growing Number Isn't the Same as a Growing Economy

A Strong GST Number Can Still Be a Weak Economic Signal

Fifteen-point-four percent sounds like an economy firing on all cylinders. The composition of that number says otherwise. Two very different engines can produce the same headline growth rate. One engine is domestic production expanding, incomes rising and consumption broadening - the kind of growth an ad valorem tax like GST is actually designed to capture.

The other engine is a weaker rupee making imported crude, electronics and machinery cost more in rupee terms and wholesale prices rising fast enough that even flat physical output generates higher nominal tax collections.

India's July numbers are running almost entirely on the second engine: import IGST grew nearly six times faster than domestic GST revenue, while the HSBC Manufacturing PMI recorded its weakest reading in five years. This distinction matters because the two engines have opposite implications for where the Indian economy actually stands.

If domestic production were driving this buoyancy, it would signal firms selling more, hiring more and consumers spending more - durable growth. If currency depreciation and wholesale inflation are driving it instead, the same 15.4% figure signals something closer to fragility dressed as strength: the same physical goods simply cost more in rupee terms, both to import and to price domestically, without any underlying expansion in what the economy is actually producing.
