Earlier
this month all eyes were on Reserve Bank Governor Duvvuri Subbarao.
Every statement of his was read as signalling whether he would raise
interest rates and by how much he would do so this time. With the
economy having bounced back and GDP growth approaching previous peaks,
the presumption was that the focus of the governor’s attention would
be the persistent and unacceptably high inflation. He would, therefore,
be willing to sacrifice investment and growth, the pundits argued,
by raising interest rates so as to moderate inflation.
There is no single interest rate in any economy. To raise interest
rates, the central bank has to select and change a particular rate,
which, in turn, is expected to move other rates in the same direction.
For some time now the relevant rate in India has been the repo rate
or the rate at which banks borrow money from the Reserve Bank of India
(RBI). An increase in the repo rate by increasing the cost at which
banks can access short-term capital is expected to induce them into
raising their lending rates and the rates they pay the depositors
from whom they mobilise much of their capital. Besides this, a change
in the interest rate would affect variables such as the prices of
assets (stocks and housing) and the exchange rate. But the main channel
through which interest rate adjustments are expected to work their
way through the economy to reduce inflation is through the impact
that the policy rate has on various commercial interest rates, such
as those for mortgages, for consumer loans, as well as for deposits.
In its most recent monetary policy statement, the RBI has met analyst
expectations by raising the repo rate by half a percentage point (or
50 basis points) from 6.75 to 7.25 per cent. It has not opted for
any other measures such as attempting to pre-empt lendable resources
by raising the cash reserve requirement (CRR) imposed on banks. The
central bank is clear about the intent of its manoeuvre. Its statement
issued on May 3 notes: “Over the long run, high inflation is inimical
to sustained growth as it harms investment by creating uncertainty.
Current elevated rates of inflation pose significant risks to future
growth. Bringing them down, therefore, even at the cost of some growth
in the short-run, should take precedence.”
To those not familiar with the discourse on economic policy, this
move must have been surprising for just one reason. Over recent months,
the Governor has more than once raised interest rates in order to
rein in inflation. Yet inflation, especially food price inflation,
has been stubbornly high, even if moderating in recent months. Clearly,
monetary policy in the form of a hike in the interest rate has not
been an effective weapon against inflation.
According to its advocates, a hike in interest rates is expected to
have a number of effects, including a fall in investment because of
the higher cost of capital, a rise in saving because of more attractive
returns, and a reduction in credit-financed consumption because of
the rise in the cost of credit. The resulting contraction in demand
(and growth) is what is expected to moderate inflation. The argument
is premised on the grounds that the central bank can influence the
relevant interest rates with its policies and that high inflation
is the result of an excess of expenditure relative to supply, determined
by the volume of available output and imports, which a hike in interest
rates could correct. To the extent that these premises are not valid,
monetary policies in general and interest rate changes in particular
will fail to have any impact on the rate of inflation.
There are three reasons why they could be wrong. The first is that
the presumed transmission of the effects of changes in the repo rate
to other commercial rates that matter may not occur. The RBI has in
the past been concerned that there is inadequate transmission of the
effects of interest rate policy, though it feels that matters have
improved considerably recently.
The second is that even if the rate hike is more-or-less generalised,
its impact on investment, savings and consumption may be too weak
to make a difference. However, in recent years the belief has been
that even if the impact of an interest rate hike on productive investment
is limited, it would substantially squeeze credit-financed investment
in housing, and credit-financed purchases of automobiles, durables
and commodities, dampening demand and growth, with attendant effects
on prices.
The third reason is that price increases may not be the result of
demand-supply imbalances caused by excess expenditures relative to
available supplies. This does seem substantially true in India, especially
with respect to food. It cannot be denied that the long-run neglect
of the food economy in India has slowed production increases and provided
the basis for supply-demand imbalances when growth recovers or accelerates.
But two factors have limited such potential imbalances. To start with,
when GDP growth occurs, its benefits tend to be unequally distributed,
with households whose consumption basket is dominated by food items
being the selective victims of budgetary cuts. Further, in recent
years India has had ample reserves of foreign exchange to import commodities
in short supply and correct supply-demand imbalances.
If the economy has still been experiencing inflation, it seems to
be the result of two other factors. One is that domestic prices are
increasingly tied to global prices partly because of the liberalisation
of trade and partly because administered prices are increasingly calibrated
to correspond to international prices. This link between domestic
and international prices has meant that the rise in the prices of
fuel, food and intermediate prices in international markets has been
transmitted to India as well, with the government doing little to
restrain this “imported” inflation. As the RBI’s Third Quarter Review
of Macroeconomic and Monetary Developments notes: “High global crude
oil and other commodity prices pose the biggest risk to India’s growth
and inflation. Persistently high inflation has kept inflation expectations
elevated. Fresh pressures from commodity prices do make 2011-12 a
challenging year for inflation management.” If inflation is influenced
by global developments, adjusting domestic interest rates may do little
to redress the problem.
The second reason for persisting inflation is that the liberalisation
of domestic trade, a reduced emphasis on public distribution and the
freedom given to traders in commodities and futures markets, have
encouraged speculation and induced an element of upward buoyancy in
prices. It is indeed true that a hike in interest rates, by increasing
interest costs on borrowing to finance speculation, could help dampen
speculation. But if the hike in interest rates is small relative to
the returns expected from speculation this may be an inadequate disincentive.
Factors like these could explain not just the persistence of inflation,
but also the failure of past attempts to hike interest rates to rein
in inflation. If inflation is imported and has little to do with immediate
demand-supply imbalance, contracting demand would not help. What the
hike in interest rates would do is increase the repayment burden on
loans taken to finance household investment and consumption, especially
investment in housing. The evidence shows that personal loans that
were an important driver of growth before the financial crisis of
2008 have seen a revival recently. Aggregate personal loans provided
by the commercial banking sector rose by 17 per cent in 2010-11, as
compared with 4.1 per cent in 2009-10. Within this category, the growth
during 2010-11 in housing loans stood at 15 per cent and in loans
against consumer durables at 22.4 per cent, as compared with 7.7 and
1.3 per cent respectively in 2009-10. Those taking on these loans
would have in recent months been faced with significant increases
in the equated monthly instalments they pay. This would not only discourage
further borrowing and new borrowers, but can lead to defaults. Given
the relatively high shares of personal loans in the aggregate advances
by banks, it could discourage lending as well. So a contraction of
demand and growth is a real possibility.
Thus, while the RBI’s interest rate manoeuvre may end up being successful
in contracting demand and growth, it is likely to fail to rein in
inflation. If that transpires it would be the result of using not
just an inadequate but a wrong instrument to address the problem at
hand.
