Japan’s rate rise puts a price on financing Indian assets in yen

The Bank of Japan’s December increase matters to India even where the investor buying an Indian asset never sends money directly from Tokyo. A position can be funded in yen, hedged in another market and settled in dollars. When Japanese rates rise, the cheapest-looking leg of the trade may become more expensive at the same time that the exchange rate moves. For India, the useful question is how much leverage is sensitive to that combination and where a quick unwind could meet thin liquidity.

What changed in Japan

On 19 December the Bank of Japan directed the overnight call rate towards around 0.75%, effective 22 December, and raised the complementary deposit facility rate to 0.75%. Its statement cited a rising likelihood of sustained wage and price increases consistent with the 2% target. The Federal Reserve, by contrast, lowered its policy target range in December. These moves show how two central banks facing different domestic conditions can shift a funding relationship even when each changes its rate by a modest amount.

The simplest carry position borrows a low-yielding currency and holds a higher-yielding asset elsewhere. The interest differential is one source of return. The price of the funding currency at repayment can dominate it. Japanese policy affects both expectations and the cost of short-dated funding. The direction of the yen also depends on what investors had already priced, so a higher policy rate does not give a mechanical forecast of the exchange rate.

A return that can disappear quickly

Assume an investor borrows the yen equivalent of ₹100 crore for one year at 1% and buys a rupee asset yielding 7%, with no fees, defaults or price movement. At the original exchange rate, the position earns ₹6 crore before costs. If the yen strengthens 6% against the rupee, the amount owed becomes ₹107.06 crore and the asset is worth ₹107 crore. The interest margin is exhausted by the exchange-rate move. If the position is hedged, the result depends on the forward rate, funding terms and basis rather than the change in the spot rate.

Institutional exposures vary. An Indian company with stable yen receipts can match part of its liabilities to them. A fund borrowing short to finance long assets may face repeated collateral calls even when it expects its investment eventually to pay. A foreign insurer can reallocate because domestic Japanese yields have become more attractive without having borrowed any yen at all. These channels have different implications for the speed and durability of outflows.

What to watch from India

The strongest argument for treating the decision as a small event is that markets anticipated much of Japan’s policy normalisation and investors have several funding currencies. The yen also represents just one part of the financing system for Indian assets. That is good reason to test market outcomes before attributing a move in the Nifty or the rupee to Japan. It is also good reason to track short-dated foreign exchange hedging costs and the depth of rupee markets during unsettled sessions.

A broad decline in Indian assets accompanied by yen strength could reflect a common shift in risk appetite. Evidence for a funding channel would be more specific. Look for stress in yen-funded hedges, unusually large changes in futures positioning, reduced turnover where leveraged investors normally trade, and pressure concentrated in positions with little capacity to absorb a quick exit. Comparing those episodes with domestic bond flows and company earnings revisions would help separate forced selling from a change in Indian fundamentals.

One useful comparison is the loss an investor can absorb without selling. A fully funded holder can wait for a hedge to mature. A position supported by a small collateral buffer can run out of cash while its expected terminal return is still positive. India’s aggregate inflow figures will struggle to distinguish the two.

The policy implication is modest and useful. Track funding currency and maturity alongside the nationality of the buyer. An investor’s passport describes where it is domiciled. Its liabilities tell India more about when it might have to sell.
