Dangers of falling rupee

Published : Jun 06, 2018 12:30 IST

THE rupee, which has been sliding in value for some time now, depreciated sharply in recent weeks, giving some cause for concern. The depreciation is largely against the rising dollar, relative to which its value has fallen by more than 7.5 per cent since the beginning of the year. The Reserve Bank of India’s reference rate, which stood at Rs.63.4 to the dollar on January 5, 2018, reached Rs.68.4 by May 24 2018 (see chart). Depreciation relative to other major currencies such as the British pound, the euro and the yen has been much less. Yet, the fall vis-a-vis the dollar is of significance, especially since much of India’s trade and its foreign debt is denominated in dollars.

Discussions on the rupee’s decline, which is projected to continue, focus on its proximate determinants. Prominent among these is the rise in the current account deficit on India’s balance of payments, intensified by the recent sharp rise in the international price of oil.

The current account deficit rose from $41.6 billion in 2016 to $73.3 billion in 2017. Further, the $23.2 billion deficit recorded in the last quarter of 2017 was significantly higher than that recorded in the previous July-September quarter ($14.4 billion) and in the last quarter of the previous year ($15.5 billion). The effects of this net outflow of foreign currency were enhanced by the retreat of investors because of rising interest rates in advanced countries and the still-hesitant recovery from the global recession.

There was a net outflow of portfolio investments of $8.44 billion in the January 1-May 25 period this year, with $7.95 billion flowing out in May alone. Since some of these trends are not triggered by developments internal to India, the problem is seen as not being India-specific, especially since the trends correspond to those in emerging markets across the world, with matters being far worse in countries such as Turkey and Argentina. While these proximate explanations are indeed valid, the emphasis on them implicitly underplays what the tendency really reflects. Periodic bouts of rupee depreciation that sometimes even trigger panic are a symptom of India being a bubble economy. There are many features that warrant it being characterised as one.

The first, and most obvious, is the fact that the purported success of liberalising “reform” lies not in the fact that India has been transformed, as intended, into an internationally competitive manufactured-exports-driven economy, but in its emergence as a favoured destination for international financial investors. The resulting large capital inflows have had a number of effects, all of which together define the bubble on which economic growth rides.

The inflows resulted in a medium-term spike in stock market values accompanied by significant volatility, with stock market valuations of many companies now at levels not warranted by potential earnings. Moreover, flows into debt markets have meant that India’s bond market—which was earlier restricted largely to government bonds—is now seeing much activity in the corporate segment, adding to the exposure to foreign debt of firms looking to benefit from low interest rates abroad.

Since money borrowed at low interest rates in the advanced economies finances a large part of the foreign financial investment, and since borrowing by Indian corporates is at low interest rates, the level of capital inflows is extremely sensitive to the interest rate in the developed countries. If interest rates in the source countries were to rise because of changed circumstances, new flows would dry up and investors may choose to book profits and exit. This could not only unwind equity and debt markets but also weaken the currency, making depreciation a reflection of the speculative investments that preceded the tendency.

Large inflows of foreign capital, by enhancing liquidity in the system, also trigger a credit boom with increased lending to the private sector (both households and firms). It is such lending that spurs demand and drives domestic market growth. Since debt-financed consumption and investment in this scenario is driven by the pressure exerted by excess liquidity on banks to increase lending, the chances are high that agents unable to service their debts will be drawn into the universe of borrowers. This increases the probability of default which, given the credit boom, can lead to systemic fragility. And such fragility can intensify the capital flight that generates exchange rate volatility.

Occurring in the context of import liberalisation, the demand fuelled by debt is likely to be more import-intensive than would otherwise have been the case. Since liberalisation in the case of countries like India does not substantially enhance exports, the import-intensive consumption and investment that accompany capital inflows generates a third source of potential pressure on the rupee in the form of a widening current account deficit. If the foreign exchange outflow on account of imports of goods and services and other payments to non-residents exceeds the inflows from exports of goods and services and remittances, the deficit, even if financed by capital inflows, sends out signals that the currency is vulnerable.

A country that cannot earn the foreign exchange needed to finance its current needs and must borrow to meet them is vulnerable to balance of payments difficulties and cannot sustain the value of its currency. However, until recently this problem was not visible because low oil prices had depressed and kept low the outflows on account of imports of goods. And when that was not true, capital inflows helped finance large deficits. That is changing now as oil prices have risen to $80 a barrel, breaching a number of “psychological barriers”. The reality that India is a country that is vulnerable on the balance of payments front is asserting itself.

In sum, liberalised trade and liberalised capital flows have substantially enhanced India’s vulnerability, of which periodic episodes of currency depreciation are a symptom. Ironically, this tendency has been concealed by the large capital inflows spurred by liberalisation and by the benefits that India derived from low oil prices. Both those advantages are now under threat as is the unsustainable growth that capital flows and liquidity infusion stimulated.


Moreover, currency depreciation has effects that enhance pre-existing vulnerability. One form that takes is inflation. If trade liberalisation has increased dependence on imports for consumption and investment, depreciation by raising the rupee cost of imports would aggravate inflation. Since one of the factors underlying depreciation is an increase in the price of a universal intermediate like oil, the potential for inflation is much higher. Inasmuch as the proximate factors underlying the depreciation of the rupee also create an environment where the growth generated becomes unsustainable, the joint effect of those factors and depreciation is a tendency to stagflation, or slow growth combined with inflation.

Inflation also forces the central bank to withdraw from the cheap money policies of the high liquidity years and raise interest rates. Since low interest rates are the only macroeconomic instrument, howsoever effective, acceptable to neoliberal policymakers committed to fiscal austerity, the situation is one where there are no means to pull the economy out of the stagflation that envelopes it.

There is one other development flowing from currency depreciation that can compound these difficulties. As noted earlier, an aspect of the surge in capital flows to markets like India is an increase in private foreign debt, as corporations seek to exploit the low interest rates prevailing in developed countries and the greater freedom to borrow abroad that liberalisation provides. Since large capital inflows make the domestic currency appear strong, much of this borrowing in foreign currency is not hedged for possible losses stemming from any currency depreciation.

When depreciation actually occurs, however, the rupee costs of servicing foreign debt rise sharply. This is also the time when the stagflation afflicting the economy hurts corporate profits, making the burden of servicing foreign debt too much to bear. The distress sale of assets that follows bankruptcies results in asset price deflation, which worsens the problem. Depending on the intensity of these effects, the bubble can burst and the game of speculation can unravel. It is for this reason that this round of currency depreciation is likely to be scrutinised carefully. It could be the round in which the bubble economy becomes unsustainable.
