Can banks reconcile all Basle II, IAS 39, and other home-host regulatory issues?
Almost all large banks currently run large and expensive projects whose
aim is to implement new so called “Basle II” new regulatory framework. The main
goal of the regulation is to improve calculation of regulatory capital
requirements related to credit risks and to motivate banks to manage their
risks better and more efficiently. The regulation sets new standards on so
called credit rating process, assessment of expected and realized credit
losses, recognition of default, as well as on credit risk monitoring and back testing.
The regulatory capital is on a receivable level mathematically calculated from
own or regulatory estimations of so called probability of default, loss given
default, and other parameters. The total regulatory capital then reflects
potential credit losses in low probability pessimistic scenarios. The banks are
required to hold sufficient (real) capital to cover such potential losses. The new
regulation will become fully effective in 2007 and the banks will run a
parallel process in 2006.
The banks also already had to implement new accounting standards set by
another well known regulation called IAS 39 effective since the beginning of
2005. One of the important new requirements is to set provisions, i.e. amounts
adjusting the book value of impaired banking receivables, based on discounted
expected cash flows. Although all publicly quoted banks must already comply
with the IAS 39 requirements a lot of fine tuning work needs to be done, in
particular in relation to the new Basle II framework.
Different
words, different meanings?
The two regulations use different words and definitions for related concepts which sometimes turn
out to be difficult to reconcile. For example Basle II uses the concept of
Expected Loss while IAS 39 systematically avoids (and essentially forbids) the
notion using rather the words “Incurred Loss” computed on the basis of the
discounted net value of expected future cash flows from impaired receivables.
Impairment must be based according to IAS 39 on an objective evidence and the
modeled future cash flows should reflect some expected problems, for example
future bankruptcy proceedings. Basle II on the other hand uses a not exactly
identical concept of default. While Basle II works with basic probability theory
tools admitting existence of different scenarios, IAS 39 wants to base the
incurred loss on only one fixed future scenario. The total IAS 39 provisions must be also compared with the total
expected loss according to Basle II. If the latter exceeds the former, the
difference will generate an additional capital requirement. However, these two
aggregates, produced for different purposes and through different processes, might
actually turn out to be quite different.
Local
regulatory interpretation and home-host issues
The international regulation is in fact implemented through local
regulations prepared by the Czech National Bank for Basle II and by Ministry of
Finance regarding IAS 39. To make things even more complex the Czech banks
belonging to international groups have to deal with different interpretations
of the two regulations coming from the local regulator and from the mother
company regulator as the financial group needs to deal with all the issues in a
consistent manner.
The Czech National Bank for example continues to use the five grade
classification scale introduced in the Nineties in order to force banks to
monitor properly financial situation of their clients and to book sufficient
provisions. According to Basle II the Banks must establish a rating scale (with
at least 8 grades) which should be used not only for credit origination but
also for an ongoing monitoring of client financial situation. The two scales
seem sometimes duplicit and a simple relationship is not so easy to find. The
classification scale is not moreover used in all European countries.
Provisioning has been traditionally tied to classification in the Czech
banking environment. Currently the banks are expected to charge specific
provisions against receivables classified as Watch, Substandard, Doubtful and
Loss. The banks may create so called portfolio provisions for selected groups
of Standard receivables. Specific provisioning however Basle II considers as a
sign of default, hence category Watch clients should be already marked as defaulted
ones. But this is not definitely the case according to the definition and usual
interpretation of the category Watch. This shows only one of many contradictions
found when all the regulations and requirements are put together.
Will the
regulations positively change the banking sector?
The banks seeking advanced Basle II standards definitely need to reshape
their credit process, quality of databases, monitoring and back testing
analyses. At the same times the banks must face and solve a number of
inconsistencies highlighted above. This will lead hopefully to an alignment between the different areas,
between the accounting world and a more mathematical world of the risk
management, and among different national regulatory environments. The key
responsibility lies with the regulators to clean up many of the old and
outdated regulations and to establish a new simple and efficient framework. The
effort of the banks should then be spent more on real improvement of their
processes rather than on puzzle solving of contradictions between different
regulations. The new and consistent regulation implemented by the banks may
then bring significant benefits to the financial community and to the whole
economy.
