Too tough or not tough enough? Developing Basel III banking rules

Under the auspices of the Bank for International Settlements (BIS), banks around the world are working their way towards implementing tougher capital requirements. These tougher rules, known as ‘Basel III’, are due to come fully into operation by 2019.

This third version of international banking rules was agreed after the financial crisis of 2008, when many banks were so undercapitalised that they could not withstand the dramatic decline in the value of many of their assets and a withdrawal of funds.

Basel III requires banks to have much more capital, especially common equity capital. The point about equity (shares) is that it’s a liability that does not have to be repaid. If people hold bank shares, the bank does not have to repay them and does not even have to pay any dividends. In other words, the money raised by issuing shares carries no obligation on the part of the bank and can thus provide a buffer against large-scale withdrawal of funds.

Under Basel III, banks have to maintain sufficiently large ‘capital-adequacy ratios’. As Essentials of Economics (7th edition) explains:

Capital adequacy is a measure of a bank’s capital relative to its assets, where the assets are weighted according to the degree of risk. The more risky the assets, the greater the amount of capital that will be required.

A measure of capital adequacy is given by the capital adequacy ratio (CAR). This is given by the following formula:

Common Equity Tier 1 (CET1) capital includes bank reserves (from retained profits) and ordinary share capital (equities), where dividends to shareholders vary with the amount of profit the bank makes… Additional Tier 1 (AT1) capital consists largely of preference shares. These pay a fixed dividend (like company bonds), but although preference shareholders have a prior claim over ordinary shareholders on the company’s (i.e. the bank’s) profits, dividends need not be paid in times of loss.

Tier 2 capital is subordinated debt with a maturity greater than 5 years. Subordinated debt holders only have a claim on a company (a bank) after the claims of all other bondholders have been met.

Risk-weighted assets are the total value of assets, where each type of asset is multiplied by a risk factor. Under the Basel III accord, cash and government bonds have a risk factor of zero and are thus not included. Interbank lending between the major banks has a risk factor of 0.2 and is thus included at only 20 per cent of its value; residential mortgages under 60% of the value of the property have a risk factor of 0.35; personal loans, credit-card debt and overdrafts have a risk factor of 1; loans to companies carry a risk factor of 0.2, 0.5, 1 or 1.5, depending on the credit rating of the company. Thus the greater the average risk factor of a bank’s assets, the greater will be the value of its risk weighted assets, and the lower will be its CAR.

Basel III gives minimum capital requirements that are higher than under its predecessor, Basel II. Thus, by 2019, banks must have a common equity capital to risk-weighted assets of at least 4.5% and a Tier 1 ratio of at least 6.0%. The overall CAR should be at least 8%. In addition, the phased introduction of a ‘capital conservation buffer’ from 2016 will raise the overall CAR to at least 10.5 per cent.

Over the past few years, banks have increased their capital cushions significantly and many have exceeded the Basel III requirements, even for 2019.

But the Basel Committee has been reconsidering the calculation of risk-weighted assets. Because of the complexity of banks’ asset structures, which tend to vary significantly from country to country, it is difficult to ensure that banks’ are meeting the Basel III requirements. Under proposed amendments to Basel III (which some commentators have dubbed ‘Basel IV’), banks would have to compare their own calculations with a ‘standardised’ model. Their own calculations of risk-based assets would then not be allowed to be lower than 60–90% (known as ‘the output floor’) of the standardised approach.

While, on the surface, this may seem reasonable, European banks have claimed that this would penalise them, as some of their assets are less risky than the equivalent assets in other countries. For example, Germany has argued that mortgage defaults have been rare and thus German mortgage debt should be given a lower weighting than US mortgage debt, where defaults have been more common. If all assets were assessed according to the output floor, several banks, especially in Europe, would be judged to be undercapitalised. As The Economist article states:

Analysts at Morgan Stanley estimate that global, non-American banks could see risk-weighted assets rise by an average of 18–30%, depending on the level of the output floor. Extra capital of €250bn–410bn could be needed, a tall order when earnings are thin and investors wary. The committee’s reviews of operational and market risks would add even more.

This question of an output floor was a sticking point at the Basel Committee meeting in Santiago, which ended on 30 November. Although some progress was made about agreeing to rules on risk weighting that could be applied globally, a final agreement will have to wait until the next meeting, in January – at the earliest.

The outlook for emerging markets

Are emerging markets about to experience a credit crunch? Slowing growth in China and other emerging market economies (EMEs) does not bode well. Nor does the prospect of rising interest rates in the USA and the resulting increase in the costs of servicing the high levels of dollar-denominated debt in many such countries.

According to the Bank for International Settlements (BIS) (see also), the stock of dollar-denominated debt in emerging market economies has doubled since 2009 and this makes them vulnerable to tighter US monetary policy.

Weaker financial market conditions combined with an increased sensitivity to US rates may heighten the risk of negative spillovers to EMEs when US policy is normalised. …

Despite low interest rates, rising debt levels have pushed debt service ratios for households and firms above their long-run averages, particularly since 2013, signalling increased risks of financial crises in EMEs.

But there is another perspective. Many emerging economies are pursuing looser monetary policy and this, combined with tighter US monetary policy, is causing their exchange rates against the dollar to depreciate, thereby increasing their export competitiveness. At the same time, more rapid growth in the USA and some EU countries, should also help to stimulate demand for their exports.

Also, in recent years there has been a large growth in trade between emerging economies – so-called ‘South–South trade’. Exports from developing countries to other developing countries has grown from 38% of developing countries’ exports in 1995 to over 52% in 2015. With technological catch-up taking place in many of these economies and with lower labour and land costs, their prospects look bright for economic growth over the longer term.

These two different perspectives are taken in the following two articles from the Telegraph. The first looks at the BIS’s analysis of growing debt and the possibility of a credit crunch. The second, while acknowledging the current weakness of many emerging economies, looks at the prospects for improving growth over the coming years.

Cleaning up the foreign exchanges

According to latest evidence from the Bank for International Settlements, in April 2013 some £3.2 trillion ($5.3 trillion) of foreign exchange was traded daily on global foreign exchange (forex) markets. About 40% of forex dealing goes through trading rooms in London. This market is highly profitable for the UK economy. But all is not well with the way people trade. There is a scandal about rate fixing.

Exchange rates on the forex market are freely determined by demand and supply and fluctuate second by second, 24 hours a day, except for weekends. Nevertheless, once a day rates are fixed for certain trades. At 4pm GMT a set of reference rates is set for corporate customers by banks and other traders. The rates are set at the free market average over the one minute from 16:00 to 16:01. The allegation is that banks have been colluding, through text messaging and chat rooms, to manipulate the market over that one minute.

Since the early summer of 2013, the Financial Conduct Authority (FCA) in the UK, along with counterparts in the USA, Switzerland, Hong Kong and elsewhere, has been looking into these allegations. Last week (4/3/14), the Bank of England suspended a member of its staff as part of its own investigation into potential rigging of the foreign exchange market. The allegation is not that the staff member(s) were involved in the rigging but that they might have known about it.The Bank said that, “An oversight committee will lead further investigations into whether bank officials were involved in forex market manipulation or were aware of manipulation, or at least the potential for such manipulation.”

Meanwhile, the House of Commons Treasury Select Committee has been questioning Bank of England staff, including the governor, Mark Carney, about the scandal. Speaking to the Committee, Martin Wheatley, head of the FCA said that the investigation over rigging had been extended to 10 banks and that the allegations are every bit as bad as they have been with Libor.

Watering down liquidity

In the wake of the financial crisis of 2007/8, the international banking regulatory body, the Basel Committee on Banking Supervision, sought to ensure that the global banking system would be much safer in future. This would require that banks had (a) sufficient capital; (b) sufficient liquidity to meet the demands of customers.

The Basel III rules set new requirements for capital adequacy ratios, to be phased in by 2019. But what about liquidity ratios? The initial proposals of the Basel Committee were that banks should have sufficient liquid assets to be able to withstand for at least 30 days an intense liquidity crisis (such as that which led to the run on Northern Rock in 2007). Liquid assets were defined as cash, reserves in the central bank and government bonds. This new ‘liquidity coverage ratio’ would begin in 2015.

These proposals, however, have met with considerable resistance from bankers, who claim that higher liquidity requirements will reduce their ability to lend and reduce the money multiplier. This would make it more difficult for countries to pull out of recession.

In response, the Basel Committee has published a revised set of liquidity requirements. The new liquidity coverage ratio, instead of being introduced in full in 2015, will be phased in over four years from 2015 to 2019. Also the definition of liquid assets has been significantly expanded to include highly rated equities, company bonds and mortgage-backed securities.

This loosening of the liquidity requirements has been well received by banks. But, as some of the commentators point out in the articles, it is some of these assets that proved to be wholly illiquid in 2007/8!

Basel III – tough new regulations, or letting banks off lightly?

Under the Basel II arrangements, banks were required to maintain particular capital adequacy ratios (CARs). These were to ensure that banks had sufficient capital to allow them to meet all demands from depositors and to cover losses if a borrower defaulted on payment. Basel II, it was (wrongly) thought would ensure that the banking system could not collapse.

There were three key ratios. The first was an overall minimum CAR of 8%, measured as Tier 1 capital plus Tier 2 capital as a percentage of total risk-weighted assets. As Economics 7th edition page 509 explains:

Tier 1 capital includes bank reserves (from retained profits) and ordinary share capital, where dividends to shareholders vary with the amount of profit the bank makes. Such capital thus places no burden on banks in times of losses as no dividend need be paid. What is more, unlike depositors, shareholders cannot ask for their money back. Tier 2 capital consists largely of preference shares. These pay a fixed rate of interest and thus do continue to place a burden on the bank even when losses are made (unless the bank goes out of business).

Risk-weighted assets are the value of assets, where each type of asset is multiplied by a risk factor. Under the internationally agreed Basel II accord, cash and government bonds have a risk factor of zero and are thus not included. Inter-bank lending between the major banks has a risk factor of 0.2 and is thus included at only 20 per cent of its value; residential mortgages have a risk factor of 0.35; personal loans, credit-card debt and overdrafts have a risk factor of 1; loans to companies carry a risk factor of 0.2, 0.5, 1 or 1.5, depending on the credit rating of the company. Thus the greater the average risk factor of a bank’s assets, the greater will be the value of its risk weighted assets, and the lower will be its CAR.

The second CAR was that Tier 1 capital should be at least 4% of risk weighted assets.

The third CAR was that equity capital (i.e. money raised from the issue of ordinary shares) should be at least 2% of risk weighted assets. This is known as the ‘core capital ratio’.

Before 2008, it was thought by most commentators that these capital adequacy ratios were sufficiently high. But then the banking crisis erupted. Banks were too exposed to sub-prime debt (i.e. debt that was excessively risky, such as mortgages on property at a time when property prices were rapidly declining). Much of this debt was disguised by being bundled up with other securities in what were known as collateralised debt obligations (CDOs). On 15 September 2008, Lehman Brothers filed for bankruptcy: the largest bankruptcy in history, with Lehmans owing $613 billion. Although its assets had a book value of $639, these were insufficiently liquid to enable Lehmans to meet the demands of its creditors.

The collapse of Lehmans sent shock waves around the world. Banks across the globe came under tremendous pressure. Many held too much sub-prime debt and had insufficient capital to meet creditors’ demands. As a result, they had to be bailed out by their governments. Clearly the Basel II regulations were too lax.

For several months there have been discussions about new tighter regulations and, on 12 September 2010, central bankers from the major countries met in Basel, Switzerland, and agreed the Basel III regulations. Although the overall CAR (Tier 1 and 2) was kept at 8%, the Tier 1 ratio was raised from 4% to 6% and the core Tier 1 ratio was raised from 2% to 4.5%, to be phased in by 2015. In addition there were two ‘buffers’ introduced.

As well as having to maintain a core Tier 1 ratio of 4.5%, banks would also have to hold a ‘conservation buffer’ of 2.5%. “The purpose of the conservation buffer is to ensure that banks maintain a buffer of capital that can be used to absorb losses during periods of financial and economic stress. While banks are allowed to draw on the buffer during such periods of stress, the closer their regulatory capital ratios approach the minimum requirement, the greater the constraints on earnings distributions.” In effect, then, the core Tier 1 ratio will rise from 2% to 7% (i.e. 4.5% minimum plus a buffer of 2.5%).

The other buffer is a ‘countercyclical buffer’. This will be “within a range of 0% – 2.5% of common equity or other fully loss absorbing capital and will be implemented according to national circumstances.” The idea of this buffer is to allow banks to withstand volatility in the global economy. It will be phased in between 2016 and 2019.

The Basel III agreement will still need to be ratified by the G20 countries meeting at Seoul on 10 and 11 November this year. That meeting will also consider other elements of bank regulation.

So will these extra capital requirements be sufficient to allow banks to withstand any future crisis? The following articles discuss this question.

  2. For what reasons may the Basel III regulations be considered too lax?
  3. When there is an increase in deposits into the banking sector, banks can increase loans by a multiple of this. This bank deposits multiplier is the inverse of the liquidity ratio. Is there a similar bank capital multiplier and, if so, what determines its size?
