The Central Bank That Says It Makes Money by Subsidizing Deposits

Most retirement money questions come down to a simple one: where is the cash coming from, and can it keep showing up? That same question applies to countries, and to the institution that runs a country's money. Right now the Reserve Bank of India is asking it of itself, in the largest currency defense India has ever staged — and the answer its governor is giving has analysts arguing with a straight face over a ten-billion-dollar ledger.

Here is the headline that started the argument, on September 11: RBI Governor Sanjay Malhotra said the central bank's foreign-currency deposit drive has not cost India money, as critics estimate, but will generate additional revenue once the dollars it collected are deployed abroad. A short version, in the voice of a banker trying to reassure shareholders: "Net, net, it will only result in additional revenues, additional income." If that sounds like a polisher's spin, it is worth seeing what the cash is actually doing — because the answer, once you trace it, is a genuinely useful lesson in where central-bank income comes from and when an apparently free deal is a bill instead.

What the RBI actually did

The story begins with a weak rupee. To prop it up, the RBI opened a special window on June 8, 2026, offering banks a cheap way to raise dollars from non-residents who live abroad — mostly the Indian diaspora. These are FCNR(B) deposits, foreign-currency accounts that let an Indian living in, say, New York hold dollars with an Indian bank for three to five years.

The catch is currency risk. A bank that takes in dollars and lends or swaps into rupees bets that the rupee will not move against it. To remove that worry, the RBI offered banks a concessional swap: it absorbs the hedging cost, so banks can raise dollars and convert them into rupees without fear of the exchange rate. In plain terms, the central bank agreed to eat the cost of protecting everyone else from a falling rupee.

The deal was generous enough that the money poured in. Dollars attracted rose from about $65 billion in late August to a record $127.2 billion by the August 31 close, a month ahead of schedule. Roughly half of those deposits carry a five-year tenor, with banks paying the most — over 7% on the longest terms — to lock funds in. It was, in scale, the re-run of a 2013 playbook under a different governor, but bigger: 2013 drew about $34 billion; this time India blew past even the late estimates of $90–100 billion.

Where the ten-billion-dollar bill comes from

Now follow the cash on both sides of the ledger, because that is where the argument lives.

The cost. The concessional swap is not free. Market hedges for three-to-five-year money cost banks roughly 2.8% to 3.3% a year; the RBI stepped in to absorb that spread, on top of paying the deposit rates themselves. Analysts who add this up arrive at a bill of as much as $10.6 billion over five years — money India effectively spends to make its own currency cheaper to hold. That is the number Malhotra is disputing.

The revenue. Here is his counter. The dollars the RBI collects do not sit idle. They join India's foreign-exchange reserves, which have already climbed to record levels this year, and the RBI invests those reserves overseas — largely in foreign government securities. The dollars earn interest. If that interest, on the roughly $127 billion raised, comes to more than the subsidy India handed out to attract it, then India is ahead, not behind.

Seen through that lens, the RBI is running a giant covered carry trade on the nation's behalf: borrow dollars from its own expatriates at a subsidized hedge, on-lend them into foreign bonds, and pocket the spread. Whether Malhotra or the analysts are right reduces to one empirical question — does what the reserves earn exceed what the subsidy costs? — and neither side has yet shown the full worksheet in public. That is precisely the sort of claim an income investor should want to see the receipts for before believing it.

The part that decides whether the income is real

There are two honest reasons to be skeptical, and knowing them is the actual investing takeaway.

First, a central bank's revenue is not a retiree's dividend. The RBI's "additional income" comes from interest on the foreign assets it already holds, and the swap program's subsidy is one more claim on that same pot. It is reasonable income, but it is earned only if the maturity profile lines up: half of these dollars are locked for five years, and global rates can fall between now and then. If the foreign bonds the RBI buys pay less later, the "net-net" surplus shrinks.

Second, the subsidy does not disappear — it migrates. The cheapest reading of the trade is that Indian banks raised dollars at a subsidized cost and promptly on-lent them abroad at higher rates through their offshore units at GIFT City, the special finance hub; public-sector banks had disbursed over $52 billion of such loans by the reporting period's end. The carry that Malhotra claims for the RBI has a twin sitting on bank balance sheets. That is not a criticism of the move by itself, but it is why "we earn more than we spend" deserves scrutiny: in a chain where a subsidy becomes one bank's spread and another's deposit, the cost is real even when the headline is positive.

What this means for your portfolio

For a U.S. investor, the temptation is to treat this as exotic background noise. It is not — it is the mechanics behind a real decision about whether to own Indian exposure at all. The FCNR(B) drive is, at bottom, India choosing to spend reserve policy to buy a stable rupee while GDP grows at a brisk 7.8%. A subsidized deposit window that genuinely earns its keep is a sign of a country financing itself smartly; one that quietly transfers ten billion dollars to banks and expatriate depositors is a tax on the rest of the economy. The rupee, the dollar flows, and the payout math above are the checks that tell you which one you are looking at — and they are the same checks to run on any income idea that hands you a yield and asks you to trust the source.

Watch the receipts, not the reassurance. If the RBI ever publishes the yield on its deployed reserves against the subsidy it paid, the argument settles itself. Until then, treat the "$127 billion raised" as a real number and the "additional income" as an unverified claim — a reminder that in investing, and in a central bank's bookkeeping, the cash source is always the question that matters, and the answer has to survive inspection rather than rhetoric.
