The CEO of a leading bank recently caused a flutter in the banking
community by demanding the abolition of the Cash Reserve Ratio (CRR).
RBI has promptly appointed a committee to look at this issue. The reserve
ratios, CRR and SLR (Statutory Liquidity Reserve), are an important
feature of Indian banking regulation. Alongside the debate about CRR,
and new thinking about how monetary policy should be conducted, we
should also review the SLR. SLR is a much
bigger burden on the banking system and has no role in monetary
policy.
What is SLR?
SLR is the requirement imposed by the regulator on commercial banks
that compels them to invest a percentage (currently 24%) of their Net
Time and Demand Liabilities (NDTL) in approved government securities.
Through this, today, 24% all the resources - deposits and
borrowings - mobilised by commercial banks are invested in
government securities. Currently bank deposits and borrowings are Rs.7
trillion which means that SLR places Rs.1.8 trillion
into purchases of government securities.
SLR creates a significant captive
source of financing its borrowing program. This has three important
implications:
- SLR reduces the resources available for commercial lending by
banks. Every rupee deployed in SLR is a rupee not invested in a private
enterprise that needs capital. There is no free lunch: when capital
given to the government, it comes at the cost of capital available to
the private sector. Any reduction in the SLR (as in the CRR) will
yield more capital for the Indian private sector. It is hence
important to critically analyse both.
- By creating a large captive source of deficit financing,
SLR effectively subsidises government at the cost of
savers and commercial borrowers. When a government has to borrow at
a competitive rate in the market, the market exerts
a check on irresponsible fiscal behavior of the
government. When there is a large captive source of borrowing, the
government is shielded from the pressures of the bond market and
is more likely to engage in fiscal imprudence.
- Such a large scale preemption of savings by the government through SLR
fundamentally distorts the interest rate structure in the economy by
artificially depressing the yield curve. This complicates the pricing of all assets in the economy.
If we want to "right-size" SLR we have to ask some important
questions:
- What is the rationale for imposing SLR?
- What
is the right level of SLR, that is consistent with this rationale and
does not result in preemption of resources from the banking
system?
- Are there other conditions that need to be imposed on SLR so
that it achieves the objectives?
The rationale for SLR
What is the conceptual foundation for
the regulator to impose SLR? The answer is: prudence. Banks raise
public deposits with a promise to redeem them at par or more. To reduce the risk of the portfolio of the bank, the regulator ensures
through SLR that at least some part is deployed in the safest assets
available. But if prudence is the reason, what is the right level of
such reserves that will ensure adequate prudence? Could it be that
imposing a requirement as high as 24% is beyond prudence, and is
actually a means for the government to preempt savings in the economy?
It is hence important to ask the next question: What SLR do we need?
What is the right level of the SLR?
Banks are in the business
of taking risk. These risks are taken by deploying public
deposits. The most potent weapon that the regulators have used against
excessive risk taking is "risk capital" which the equity capital
committed by the banks owners. In fact, the entire edifice of modern
day bank regulation is based on provision of risk capital as a buffer
against risk taking by banks. If we believe, as do most
regulators, in risk capital as the buffer against risks, then it makes
eminent sense for banks to hold this capital safely. This would
logically lead us to conclude that prudence should demand that the
bank's risk capital be held in very safe assets. In India, the risk
capital requirement is 9% of risk assets which translates roughly to
6.5% of NDTL (given that the risk assets are typically 70% of
NDTL). Therefore, the policy prescription should be: Banks must
hold their entire risk capital in safe assets which should include
both CRR and SLR.
Even if we assume the CRR is zero, this means
that the theoretically right level of SLR would be around 6.5% of
NDTL. If we scan the international landscape, this is the sort of
number that we see in most countries. It is reasonable to argue that
an SLR value above 6.5% of NDTL is motivated by pre-emption and not
prudence. When the regulator prescribes a level of 24% for SLR, 6.5
percentage points are for prudence and the remaining 17.5 percentage
points is really preemption by the government.
The composition of
SLR
The next important question about SLR is about its
composition - what investments should qualify as SLR investments?
Currently securities issued by the sovereign (Central and State
Government bonds) are the only ones that are allowed as SLR
investments. But if we accept prudence as the logic for
SLR, then the regulation must make sure that these investments are as
safe as they can be. This raises concerns about the rating threshold
and of concentration risk. If Indian government securities are rated
BBB and that of New Zealand government are AAA, it makes sense for banks to hold SLR in New Zealand Govt
securities. Also, there should be limits on any individual issuer of
securities, reflecting the standard risk management practice followed
by any portfolio manager.
The ideal SLR
Putting all the
arguments above provides us an ideal construct of SLR as follows:
- SLR is imposed for the purpose of prudence and hence the
operative principle is that banks should hold all the regulatory
required risk capital in SLR - The level of SLR should be consistent
with the objective of prudence and anything over such a prudential
level should be considered as preemption, which should be gradually
eliminated. - SLR should be invested in top rated
securities available globally; furthermore there should be
concentration limits on single security and issuer
Dual limits structure for SLR
In the short term, it would be hard
to come close to the ideal SLR outlined above. But there are
some incremental changes that can be made without fundamentally altering the
current framework that could provide banks with much greater
flexibility.
The regulator could prescribe 2 separate limits as
follows:
- L1: is the minimum level of SLR that a bank would
normally maintain - L2: "core" SLR - a minimum below L1 that the
banks can go down on SLR as long as the difference is only through
repo arrangement on SLR with another bank
What does this mean?
Let us assume that L1 is pegged at the currently prescribed level of
24%. We then define another limit, L2, which is closer to the
prudential requirement of 6.5%. For simplicity, let us assume that L2 is
set at 10%. This policy would demand that all banks maintain SLR at 24%
but could go down this level upto 10% if and only if they enter into a
repurchase agreement (repo) with another bank. Such a policy will
mean that the banking system as a whole will continue to hold 24% SLR
and so the government will continue to have access to this captive
source of funding deficit. However, individual banks would be able to go down to
lower levels if they have commercially viable opportunities to do
so. Without diluting the overall investment by the banking system in government
securities, it would provide significant flexibility to individual
banks on commercial lending. In this respect, it is analogous to the
idea of tradeable certificates for priority sector lending.
