Five Indian banks have together raised $3.55 billion through dollar-denominated bonds as lenders move quickly to draw on the Reserve Bank of India's (RBI) concessional swap window, CNBC-TV18 reported. The industry expects total fundraising through such bonds to reach as much as $15 billion. How close actual issuance comes to that figure — and how it compares with the RBI's last major dollar-attracting programme — will show how heavily banks come to rely on this route.

How the swap window works

The RBI, India's central bank, operates swap facilities through which banks can exchange US dollars for Indian rupees, with the transaction reversed at an agreed future date. By issuing dollar-denominated bonds overseas and swapping the proceeds into rupees through the concessional window, banks can obtain rupee funding on terms more favourable than prevailing market rates. The RBI, in turn, receives dollars, which add to its foreign exchange reserves — the country's principal buffer against external shocks. The central bank has deployed special swap facilities in the past to attract dollar inflows, most notably the FCNR(B) swap window of 2013, which was opened during a period of sharp depreciation pressure on the rupee and drew roughly $34 billion through deposits from non-resident Indians.

Dollar bonds as a funding route

Dollar-denominated bonds allow Indian lenders to tap a broad pool of global investors. Once the proceeds are converted into rupees via the swap, the foreign-currency borrowing becomes usable domestic funding. Overseas fundraising of this kind by Indian banks and companies falls under India's foreign-currency borrowing regulations, including the External Commercial Borrowings (ECB) framework administered by the RBI, which prescribes rules on borrowing amounts, minimum maturity, and permitted end use of funds.
