THE BASLE II ACCORD is expected to be implemented in
2007 as the basis for global bank regulation, directly
affecting the capital required to support an estimated $50
trillion of global credit exposures. Like Basle I in 1988,
Basle II will have consequences for a wide range of banking
activities, and has already led to extensive political
lobbying and pre-emptive strategic positioning.
We estimate that banks will spend around $25 billion (five basis
points of assets) preparing for implementation, with the largest
banks typically investing $50 million to $200 million over five
years. Investments in credit risk measurement and management (which
have the strongest impact on risk-weighted assets - RWAs) and
supporting IT will be the most significant. Maximizing value from
these expenditures should be a key element in any bank's strategy,
and is increasingly being given priority at the highest levels in
leading banks.
The changes in capital requirements that are likely to result
from the better alignment of regulatory capital with banks' risk
profiles - the core purpose of Basle II - along with the impact of
the apparently softer Pillars 2 and 3 will drive structural changes
in the financial services industry. The relative changes in capital
costs will alter the perceived attractiveness of individual
products, countries and businesses, leading to strategic and
tactical shifts as players respond to the new environment.
The part of Basle II discussed most often concerns the
minimum capital requirements spelt out in Pillar 1, which forces
capital to be more closely aligned with the risks of portfolios
held. Banks are offered two general approaches for calculating
capital requirements: standardized and internal ratings based
(IRB). IRB has two further sub-approaches: foundation and advanced.
We summarize the differences between these with respect to risk
weights, parameters and mitigation in Figure 1.
We have calculated the impact of these requirements across
geographies, bank types, retail product types and corporate
customer segments using all three compliance standards as laid out
in the most recent quantitative impact study (QIS 3).
In total, for banks in North and Latin America and in Europe,
aggregate credit risk capital requirements will be about 3% higher
than currently, if all banks remain at standardized level, but with
a reduction for foundation IRB of around 12% and a larger reduction
for advanced IRB of around 17%.
In addition, the new operational risk capital charge (not yet
finalized) will add an expected average 12%, so that under the IRB
foundation approach the total banking industry requirement is
roughly unchanged.
Asset management, advisory and custodial services, which are
currently treated as "risk-free", will thus become subject to
explicit capital requirements, forcing banks to reassess the merits
of allocating capital to such operations.
Winning and losing lending portfolio segments stand out clearly.
The major losers are sovereigns and banks, which enjoyed very low
risk weightings under Basle I, and small and medium-size
enterprises (SMEs), whose lower average credit quality will attract
higher capital requirements. Coincidentally, all three of these
segments are to some extent distressed and currently feeling the
credit crunch. This will have a negative impact on the funding of
SMEs, a concern that drove the German government's successful
lobbying of the EU on this topic.
Also, public funding debates will need to take note of the
structural impact caused by a likely disincentive for banks to
provide credit to local and national governments, combined with a
possible reduction in inter-bank liquidity.
One of the questions raised after earlier impact studies
concerned the incentives for banks to develop more sophisticated
risk methodologies for SMEs, since IRB approaches appeared to
assign these significantly increased capital requirements.
It appears this has been resolved in QIS 3, since reaching IRB
advanced will give a smaller increase in capital requirements for
this important customer segment than standardized. However
sovereigns are still subject to such a misalignment of incentives,
a problem exaggerated by the recently introduced maturity
adjustments implicit in the capital calculation.
The frequently complex structures and importance of collateral
for many types of specialized lending - for example commercial real
estate, asset finance and project finance - will mean that unless
institutions can reach IRB advanced, they will be significantly
disadvantaged from a regulatory capital perspective. For project
finance, our results confirm that the modified foundation approach
(there is no standardized approach for project finance) has risk
and capital weights, effectively forcing players to develop
sophisticated risk tools or suffer heavy regulatory capital
penalties, leading to the possibility that they will exit the
market.
In response to the better alignment of regulatory capital with
underlying risk, it is possible that super-monolines will emerge,
with retail or large corporate portfolios taking advantage of
capital requirement reductions, as more homogeneous portfolios make
IRB advanced more easily achievable.
Similarly, many banks will come under increasing pressure to
scale down or exit businesses in which they hold only relatively
small portfolios. Only the most sophisticated of the banks are
likely to manage broad portfolios and compete successfully on this
basis.
Geographical gainers and
losers
Looking across geographies, North America and the Nordic
region look set to gain most from the new regulations. The fact
that they have relatively large retail markets (compared with
sovereign and interbank exposures) and higher recovery rates
primarily drives these results. In general, across all geographies,
the relative size of retail portfolios is the key driver of the
observed differences.
The overall impact on capital levels nationally across Europe
could have serious ramifications for competitiveness. As the EU
presses for regulatory harmonization, banks will be liberated from
national regulatory protection and banks in northern Europe look to
be getting an advantage in a more competitive environment via lower
regulatory requirements.
Incentives for banks in emerging markets are a potential worry,
as IRB assigns these a lot of capital. Following the most recent
debate and the interest that is being taken by the IMF, Basle II is
very much on the agenda for the emerging markets, albeit with
possible delays.
This will also have an obvious knock-on effect on western banks
that have emerging-market subsidiaries, not least Spanish banks in
Latin America (all numbers in Figure 2 exclude non-domestic
subsidiaries), and a possible disincentive to invest in developing
countries might have negative implications for their general growth
prospects.
