After the storm

In the midst of a crisis, it's easy to forget that eventually some kind of normality will return. However, by examining the causes of this crisis, a clearer picture of the future financial landscape emerges.

In the midst of a crisis, it's easy to forget that eventually some kind of normality will return. To understand what the financial sector might look like once the current financial crisis has passed, it is valuable to identify the causes of the crisis. At the risk of oversimplification, it can be attributed to four major factors.

The first is the growth of financial products and practices which involved high leverage and were sustainable only under conditions of increasing asset prices and investor confidence.

Sub-prime mortgage lending in the US is the obvious example which triggered the crisis, but the problem was more pervasive due to the second factor –uncontrolled (and not well recognised) liquidity creation. Financial engineering has prompted the growth of liquidity creation techniques based around collateralised lending (such as repos, securities lending, margin lending), where active securities markets for the collateral meant that lenders did not themselves feel exposed to significant liquidity or counterparty risk. Although asset price inflation was high, central banks, focused on consumer price inflation targets and real sector activity and did not respond by attempting to restrict liquidity and 'pricking the bubble'.

A third factor was the growth of the largely unregulated 'shadow banking' sector, involving investment banks, hedge funds, SIVs, conduits etc., and the construction of complex financial instruments and techniques which saw risk spread throughout the global financial sector and significant interdependencies created.

Finally, there was an absence of public information about the level and distribution of risk in the financial system. Inability to assess the risk positions of potential counterparties meant that a crisis-induced response for many institutions was simply to cease extending credit.

Indeed analyst Gary Gorton links the onset of the sub-prime crisis to the introduction of the ABX indices in 2006 which provided the first aggregate, market-based estimates of sub-prime linked securities values. While concerns about US house prices and sub-prime mortgage defaults were also emerging, the indices enabled market participants to express, and trade on, views about the implications for CDOs, whose values were ultimately linked to US house prices via intricate relationships involving complex securitisations of sub-prime mortgages.

Closer to home, the lack of public information has been seen in the absence of reliable public data about short selling and securities lending. Given the role these techniques play in linking equities and funding markets, both market participants and policy makers have been flying blind in making important decisions where knowledge about aggregate positions taken by other participants is valuable information.

Knee-jerk responses

Crisis-induced responses by governments have focused primarily on offsetting the immediate effects of the crisis rather than addressing the underlying causal factors.

First, there have been actions to shore up public confidence in national banking sectors, involving broad extensions of deposit insurance, guarantees, and government equity injections into or full or partial nationalisations of banks.

Second, there have been actions to unfreeze and/or restore liquidity to asset markets and financial institutions, via widening of acceptable collateral in central bank repurchase agreements, and government purchases of particular types of assets (including mortgage backed securities).

Central banks have also increased aggregate liquidity through their open market operations to cater for the fear-induced increase in demand for liquidity and to lower official interest rates to offset adverse effects on the real economy arising from higher credit spreads on private sector lending.

A third response has been the "bail out” of systemically important non-bank financial institutions such as investment banks in the US.

The interdependencies within the financial system have been reflected in their roles as prime brokers for hedge funds, significant counterparties in derivatives transactions, and providers of credit through collateralised lending techniques. Ultimately, the disruption to asset markets from disorderly failure was deemed (with the aid of hindsight from the Lehman example) to be unacceptable.

A fourth response has been the introduction of new, temporary, regulations on financial markets and institutions. Particularly notable here has been the introduction of bans on short selling of (some or all) equities on national stock exchanges, driven by concerns about destabilising speculation.

Run on the non-banks

These responses (and the crisis itself) have had significant short term, and potentially lasting, impacts on the competitive position of various financial institutions. Non-bank investment vehicles (finance companies, managed funds etc) have suffered outflows, partly due to nervous investors being attracted to government guaranteed deposits, but also reflecting the desire to avoid further losses on risky investments in such a bear market environment.

Hedge funds (and others) using trading strategies based on taking short positions have found their business models undermined by bans on short selling.

Looking ahead, a number of changes in the financial sector and in policy approaches can be anticipated.

First, it's worth considering some likely policy and regulatory changes.

It is likely that central banks will be tasked with focusing also on asset price inflation as a policy goal, rather than the previous, failed, approach of attempting to ensure a "soft landing” from the bursting of speculative bubbles.

Also, to have greater effects on financial markets, new instruments of policy will be needed. 'Macro-prudential” policy can be anticipated, in which capital requirements of prudentially regulated institutions are varied depending on economic and financial conditions. This may also include changes to allowable provisioning for losses, involving building up of loss reserves in good times and consequent smoothing of reported profits.

Combined with concerns about the impact of mark to market (or model) accounting requirements on financial institutions in this period of market disruption, recently agreed international accounting standards will be subject to scrutiny.

Deposit insurance arrangements and the scope of prudential regulation will be subject to review.

A 'safety haven' for unsophisticated investors is required, but recent events have reinforced the perception of 'too big/too important to fail', extending perceived protection to a vastly expanded range of financial products and institutions.

Paradoxically, investment banking activities are being increasingly linked with traditional banking, worsening this problem. While holding company structures can notionally separate different types of activities, the potential for allowing failure of one part of the structure (such as the investment banking arm) while maintaining confidence in the rest (including commercial banking) seems limited.

Basel II review

The recently introduced Basel II capital accord will also need further review. Although some of the regulatory failings exposed by the sub-prime crisis can be traced to inadequacies in the original Basel accord (such as allowing banks to provide 364 day liquidity facilities to their SIVs and conduits without capital requirement implications), there are many new banking practices not well covered by the accord.

Indeed, the foundations of the new accord have been severely shaken. Bank internal risk models have not performed well – raising questions about the merits of relying on them for determination of capital requirements as done in the advanced approach of Basel II. Similarly, the credibility of ratings agencies has suffered, also raising questions about the fundamental role of ratings in determining capital requirements under the standardised approach of Basel II.

Whether the 'shadow banking sector' is likely to be subject to regulation is an unknown. But it is almost certain that it will be subject to greater reporting requirements to ensure that in future policy makers and market participants will have better information on which to base decisions.

Balancing the requirements between protecting commercially valuable private information and generating socially valuable aggregate information is challenging – but enforcing information disclosure should be relatively simple by linking it to AFS licensing requirements.

Greater information is also available when financial claims are traded in organised exchanges rather than over-the counter markets involving bilateral trades where only the participants are aware of prices and quantities. Reporting requirements for OTC trades (by AFS licensees) can rectify that, but it may be expected that organised exchanges will experience growth.

A further rationale for the growth of organised exchanges arises from the inherent faults in the business models of a variety of unlisted investment vehicles. Unlisted property and mortgage trusts claim to offer investors liquidity, via redemption facilities, but hold illiquid assets which can lead to a need to freeze redemptions when substantial outflows occur.

Similarly, investors in finance company debentures and a range of other investments rely on the issuer/manager determination of exit prices prior to maturity. Not only do investors face the risk of unfavourable pricing in those circumstances, but there is no mechanism for aggregation and expression of public information about the value of the underlying assets – as occurs (albeit imperfectly) when securities are traded on an organised exchange.

At the same time, organised exchanges appear to be subject to excessive short term trading and potentially destabilising speculation, reflecting the dramatically reduced trading costs due to modern technology. While it is desirable for valuable private information about economic fundamentals to be incorporated into asset prices by the actions of traders, modern asset markets have, arguably, become much like casinos. Much trading appears to be based on perceptions of likely short term changes in market psychology or mood or on profit opportunities arising from liquidity needs forcing other participants to unwind current positions (such as short selling based on perceptions that price points leading to margin calls will be reached).

The Tobin tax

Reflecting these concerns, there may be renewed interest in some variant of the "Tobin tax”, a proposal by Nobel prize-winning economist James Tobin originally suggested for application to foreign exchange markets. The proposal (often described as "throwing sand in the wheels”) envisages some small tax rate on asset transactions which penalises, and thus inhibits, short term trading, but has little effect on long term position taking.

Increased attention is also likely to be given to the inherent agency problems in the financial sector. The sub-prime crisis reflects, at least in part, the lack of accountability and wrong incentives for mortgage originators and securitisers who were not exposed to the risk associated with mortgages and structured products created and on-sold.

Many investors were sold products with unsuitable risk characteristics by financial product sellers and financial advisers with remuneration structures linked to sales volume, which generated conflicts of interest.

Focusing solely on the sellers of financial products, however, only addresses part of the problem. There is a fundamental disjuncture between the sophistication of financial products created and the competence of both investors and borrowers to fully understand the risk and return (or cost) characteristics. And the lack of financial sophistication applies at both retail and wholesale level!

Finding mechanisms for inducing (or preventing) the financially unsophisticated from allowing greed to outweigh common sense is indeed challenging. Compulsion, prohibitions, specification of default options, taxes and subsidies, are tactics which warrant attention (and some of which have been used in dealing with retirement financing).

Going forward, the financial system is bound to be a more subdued place for at least a few years. The excesses of financial engineering will not return for a while, although relatively simple financial innovations, such as basic securitisation techniques, should eventually recover. But even here, there is the potential for improvements on the basic model such as use of the 'covered bond' approach common in Europe, where the securities issued remain a liability of the bank originating the mortgages. And quickly winding down the role of governments in purchasing mortgage backed securities (at prices that cannot be assessed as appropriate for the risk involved, given the current absence of a private market) is an important agenda item.

But probably the major dilemma lies in the likelihood of increased concentration and inter-linkages in the financial sector. Major banking groups dominate not just banking, but also funds management, financial advising and planning, and securities businesses. Most of the other participants in the financial sector are dependent upon them for at least some services crucial to their business. Payments services, prime brokerage, and stand by liquidity facilities are some examples.

In these circumstances, as has so recently been demonstrated, governments are simply not able to adopt a caveat emptor posture and allow such institutions to fail. And permitting a relatively small number of such institutions to dominate the entire financial sector brings with it the problems of concentration of power, inadequate competition, and excessive profits.

There is no hard evidence that a concentrated banking sector is more conducive to financial stability. And there is no good evidence as to whether a concentrated banking sector leads to adequate or inadequate competition in financial services.

Finding the appropriate regulatory structure and framework for the financial sector which generates financial stability, adequate competition, and promotes value adding financial innovation is the challenge that lies ahead.
