Financial Markets - An Assessment of Reforms

Credit Risk, Capitalisation and Efficiency

The relationship between credit risk, capitalisation and efficiency has been tested empirically using regression analysis (simultaneous equation system). The empirical specification examining these issues in respect of three size classes of PSBs, viz., large, medium and small1 is addressed in Box VI.3. The broad findings emerging from the analysis are set out below:


Box VI.3
Credit Risk, Capitalisation and Bank Efficiency : Evidence from India

Keeping in view the theoretical observations on the interlinkages among the reform of credit risk, capital and efficiency, an attempt has been made to empirically examine the same for the 27 Indian PSBs for the period 1995-96 to 2001-02.1 These banks were disaggregated into three size classes (large, medium and small), based on their total assets at the beginning of the sample period. The size class classification permitted an equal number of banks within each of the three categories.

A banking firm can achieve a certain level of overall risk exposure by choosing one of the several alternative convex combinations of credit risk and capital. As a consequence, these two types of risks have been modelled as simultaneously determined. Credit risk has been measured by the ratio of gross non-performing loans to gross advances (GNPA). In a sense, credit risk is measured ex-post. Capital adequacy, on the other hand, is measured by the ratio of capital to risk-weighted assets (CRAR). The inefficiency (INEFF) was derived following the intermediation approach.

The empirical specification in the simultaneous equation system comprised the following three equations:

GNPA = f1 (CRAR,, INEFF, NPRIOL, ADVGR, ADVGRSQ) (1)
CAPITAL= f2 (GNPA, INEFF, RoA, RPL, RPH, SIZE) (2)
INEFF = f3 (GNPA, CRAR, ADVGR, ADVGRSQ, DIVEST) (3)

where,

NPRIOL = ratio of loans given to non-priority sector to total loans;
ADVGR = annual growth rate of total loans; ADVGRSQ=square of ADVGR;
RoA = return on assets;
SIZE = natural logarithm of total asset;
DIVEST = Government ownership, defined as a variable which equals 1 in the year in which the bank has made an equity offering (and all subsequent years) and zero, otherwise;
Low regulatory pressure: RPL=[(1/Stipulated CRAR)-(1/Actual CRAR)];
High regulatory pressure: RPH=[(1/Actual CRAR) - (1/Stipulated CRAR)]

GNPA, CRAR and INEFF are the three exogenous variables. The model is closed by including endogenous variables that have explanatory power for each of the exogenous variables.

GNPA is expected to be related to the loan portfolio composition. Accordingly, the ratio of non-priority sector loans to total loans (NPRIOL) has been included as an explanatory variable. The effect of loan growth on the quantity of bad loan is controlled by using the one-year loan growth rate (ADVGR). To allow for the possibility of a U-shaped relation between loan growth and bad loan, the square of loan growth term (ADVGRSQ) has also been included.

The CRAR is expected to exhibit positive relation with profitability, owing to the plough back of earnings into reserves. This suggests the RoA as a plausible explanatory variable. In addition, the effect of bank size is controlled by including the natural logarithm of total assets (SIZE). In order to capture the effects of capital regulation, regulatory pressure variables, denoted by RPH (high) and RPL (low) was included (Jacques and Nigro, 1997). By construction, RPH should have a positive effect on capital ratios, because one of the options available to banks to meet the prescribed capital standards is simply to raise capital. As regards RPL, although banks with risk-based capital ratios in excess of the stipulated minimum are not explicitly constrained by the prescribed capital standards, it might turn out that the risk-based standards induce them to reduce their ratios (the opportunity cost of holding additional capital might be high).

Finally, in the INEFF equation, the effect of loan growth is controlled by introducing ADVGR and ADVGRSQ. To the extent that a low to moderate loan growth rate partially reflects on managerial quality, while a high growth rate is reflective of managerial entrenchment, the relation between growth and efficiency may turn out to be U-shaped. Finally, the effect of Government ownership is controlled by DIVEST. The variable intends to ascertain whether the divestment of Government ownership in state-owned banks has had an effect on efficiency.

The estimation procedure employed was pooled time-series, cross-section observations using the two-stage least squares (2SLS) procedure separately for each size class.

The choice of public sector banks is dictated by two considerations. The first is the availability of a consistent and published dataset. Second, given the wide heterogeneity across state-owned banks in terms of their product sophistication and customer orientation and the fact that these account for the majority of banking assets, a study of the state-owned banks enables to draw broad inferences about the banking sector as a whole.

Three variables were selected as inputs: total funds (deposits plus borrowings), fixed assets and total number of employees. The relevant outputs are loans and investments. In order to mitigate the price effects, the variables were deflated by the relevant deflators. Accordingly, the cost of funds, repairs and maintenance and per employee cost was taken as the relevant input prices. A stochastic frontier cost function with composite error terms and standard distributional assumptions was specified. The total cost was approximated by a translog function with multiple inputs and outputs

The adjusted R2 in case of the INEFF equation was found to be the lowest. The result was, however, in consonance with evidence for the US banking industry, wherein the explanatory power of this variable was also found to be quite low (Kwan and Eisenbis, 1997).

The disadvantage of such a variable, however, lies in the fact that it does not consider the extent of divestment. In other words, a bank, which has divested 20 per cent of its equity capital is treated at par with a divestment of, say, 35 per cent. Notwithstanding its limitations, DIVEST enables an inference of the impact of Government shareholding on efficiency

The 2SLS procedure performs the reduced-form regression of the dependent variable on all the pre-determined variables in the system (stage 1), obtaining the estimates of the dependent variable and thereafter replacing the dependent variable in the original equation by its estimated value and applying ordinary least squares to the transformed equation (stage 2). The estimators thus obtained are consistent, i.e., they converge to their true values as the sample size increases.


  • Greater soundness (higher capital position) leads to improvement in efficiency, particularly in the case of small banks. Improvements in efficiency, especially in respect of small banks, also have a positive effect on their soundness. Furthermore, the positive impact of efficiency on soundness is reinforced as higher profitability was found to be leading to increased soundness in the case of small and medium-sized banks.

  • Better asset quality (greater stability) promotes greater efficiency in the case of medium-sized banks but not in case of other two bank size classes. However, the relationship between asset quality and efficiency was not found to be mutually reinforcing for any of the bank groups.

  • Soundness and stability were found to be reinforcing each other. In other words, adequately capitalised banks in the small and medium categories are less prone to credit risk. In the case of latter category, in particular, improvements in credit risk management also had a beneficial effect on stability through improvements in the capital position.

  • On the whole, the empirical findings suggest that capital, credit risk and efficiency are interlinked, and to a certain extent, they reinforce and complement one another.

To conclude, various reform measures introduced in the banking sector have resulted in remarkable improvement in banks’ capital position as reflected in the overall increase in their capital adequacy ratio. Asset quality of the commercial banking sector on the whole also improved markedly inspite of gradual tightening of prudential norms and the slowing down of the economy in recent years. There is evidence to suggest that competition in the banking industry has intensified. Significant improvement was also discernible in the various parameters of efficiency, especially intermediation costs, which declined significantly. Profitability of commercial banks, on the whole, improved significantly despite a decline in spread and higher provisioning following the introduction and subsequent tightening of prudential norms.

It was found empirically that in the case of the Indian banking sector, ownership did impinge on the efficiency of banks as old private sector banks performed better, in terms of various parameters, than those PSBs which divested their equity in the 1990s, which, in turn, performed better than the fully Government-owned banks. The performance of new private sector banks was well above all other bank groups. At the same time, however, it needs to be noted that the fully Government-owned banks showed remarkable improvement in almost all parameters in recent years and that their performance is gradually converging with that of better performing banks. Finally, financial soundness and stability tended to reinforce each other in the case of Indian banking sector and that there was no evidence of various stability measures impinging on the efficiency of financial institutions.

Notwithstanding significant improvements as set out above, there are several challenges that lie ahead. Much of the improvement in the capital position of banks in the initial years, especially in the case of PSBs, was due to recapitalisation support from the Government. This is not a sustainable option. Banks, therefore, need to further improve their profitability so that they can increase their capital funds through internal generation. Improved financial performance is also necessary when banks enter the market for raising capital. Notwithstanding improvement in the asset quality, the level of NPAs appears high by international standards. A major challenge in the years ahead, thus, lies in bringing down the non-performing assets. Alongside, provisioning for non-performing assets also needs to be enhanced. Tightening of the provisioning norms and a switch-over to the forward-looking provisioning would further enhance the stability of the Indian banking sector. A related issue concerns a large amount of loss assets being carried by banks in their books. Such assets, which ideally should be written off, still constitute about 10 per cent of the gross NPAs mainly for the reason that many of the accounts are under litigation and cannot be written off before resolution of such cases. Profitability in India is still low as compared to several developing countries and banks need to make concerted efforts to improve their profitability by diversifying their business, especially into non-fund-based activities.

Co-operative Banks

The co-operative banking sector in India comprising urban co-operative banks (UCBs) and rural co-operative banks such as state co-operative banks (StCBs) and district central co-operative banks (CCBs) has an extensive branch network and reach in the remote areas. Though much smaller as compared to scheduled commercial banks, co-operative banks constitute an important segment of the Indian banking system and have traditionally played an important role in creating banking habits among the lower and middle-income groups and in strengthening the rural credit delivery system.

The reform process has tried to achieve regulatory convergence among various financial intermediaries in view of their systemic importance. Therefore, the basic objectives and instruments of reforms for co-operative banks have been the same as for SCBs. However, given the special characteristics of co-operative banks, they have been extended certain dispensations in terms of pace and sequencing of reforms.

Parameters Relating to Stability

Information on CRAR of co-operative banks is not available. Therefore, for analysing the capital position of co-operative banks, alternative measures, viz., share capital to asset ratio, owned funds to asset ratio and compliance with minimum capitalisation norm under Section 11(1) of the Banking Regulation Act, 1949 were examined. Movements in share capital to asset ratio as well as owned funds to asset ratio indicate that there was very little perceptible improvement in capitalisation of co-operative banks between 1998 and 2002. Asset quality of co-operative banks during the same period also did not show any discernible improvement in any segment. Gross NPAs in absolute terms increased significantly in respect of all types of co-operative banks. However, NPAs as a ratio of total loans outstanding remained more or less unchanged for all types of co-operative banks barring scheduled UCBs, in respect of which they increased sharply from 2001. The increase in the stock of NPAs over the years reflected partly the impact of gradual tightening of income recognition and asset classification norms and partly general deterioration of recovery performance.

Parameters Relating to Efficiency

During the period from 1997-98 to 2001-02, interest spread of scheduled UCBs declined sharply and remained in alignment with those of commercial banks, while there was no significant change in spread of rural co-operative banks. This reflected greater competition between scheduled UCBs and commercial banks and general insulation of rural cooperative banks from such competition. Operating expenses as a proportion of assets, however, declined significantly across all segments of co-operative banks with the movement in respect of scheduled UCBs closely following those of SCBs. Profitability of scheduled UCBs, however, deteriorated, while there was some improvement in profitability of rural co-operative banks between 1997-98 and 2000-01.

The foregoing analysis, thus, shows that since the introduction of reforms, there has been very little perceptible improvement in either stability or efficiency of co-operative banks. In particular, the asset quality and profitability of scheduled UCBs showed some deterioration in the reform period. Positive impact of reforms, as has been witnessed in the case of commercial banking sector, may take longer to get manifested for co-operative banks given the late start of the reform process in this sector. Unless such a positive scenario evolves for the co-operative banking sector in the near future, the financial health of many of these banks would continue to remain a cause of concern.

It is significant to note that introduction of reforms and the consequent increase in competition has resulted in some convergence in operations of commercial banks and co-operative banks, especially scheduled UCBs. However, in the face of lower spread, while the commercial banking sector could maintain its profitable status, scheduled UCBs as a group incurred losses. Furthermore, while most of the loss-making commercial banks are relatively small, in the case of UCBs some of the large banks are incurring losses and this increases the vulnerability of the whole segment.

Detection of irregularities in a few UCBs in the recent past has raised concerns about the conduct of the management in co-operative banks. Although remedial measures have been taken to limit the contagion effect of such disturbances spreading to other segments of the financial sector, and mechanisms have also been put in place to avoid recurrence of such developments, the current duality of control over co-operative banks is an impediment to effective supervision of such entities. For this purpose, the Reserve Bank has suggested the establishment of a unified supervisory authority for UCBs and the related amendment of the Banking Regulation Act, 1949 is currently under consideration of the Central Government.

Between 1996-97 and 1998-99, deposits of UCBs grew much faster than those of commercial banks. Co-operative banks are allowed to offer higher interest rates than SCBs on saving and current account deposits. This, coupled with the same deposit insurance protection for co-operative and commercial banks, might have resulted in the higher deposit growth in co-operative banks. Such a situation, however, might create a moral hazard problem since in order to compensate for the higher cost of deposits mobilised by them, co-operative banks could deploy such funds in riskier avenues. Steps such as stricter entry point norms, enhanced internal control and corporate governance norms, effective supervision and increased market discipline through greater disclosure for co-operative banks are required to address the problem.
