FAQ
Does Bhutan get paid for sharing a currency with India?
The comparison is the Common Monetary Area in southern Africa, where the rand circulates across four states and the three smaller members are paid a formula-driven share of the seigniorage — the profit a central bank earns from issuing currency. Bhutan has run the same arrangement with India since 1974 and has never raised the question.
The book is careful here: the roughly Nu 855 million a year figure is a constructed estimate built on soft inputs, not an audited entitlement, and the argument is explicitly not that India owes Bhutan money. It is that an arrangement which is currently implicit could be made explicit and indexed — a diplomatic question Bhutan has not yet put on the table.
The full reasoning is in Paradox #61, with the related currency-peg cost examined in Paradox #62.
