STRESS-TESTS: EU FINANCIAL REGULATORS COMPLY WITH POLITICAL BIAS MORE THAN BASEL II

basel carnival.jpg
Stress-tests are supposedly harmonised, at least for banks in the banking sectors of each country, but not across all EU member states, to test for shocks to a country's banking system when current risk assessments are suddenly inverted by falls in investment, in consumer demand, savings, loans, and by fast rising long term bond yields, and when presumably wholesale financial markets become 'one-way' (either buy-buy or sell-sell)!  The indicator values of sudden change are provided by the EU regulatory authorities, but in a narrative form and using an abstractionist, sometimes over-coy, language that is farcical.

This is not how the CRD and BIS Basel II regulations and guidelines specified the laws for this.

In the original regulations, stress-test calculations are expected to be conceived by the banks from their own macro-economic models including their own models of their banking sectors and of how and where their banks fit within those sectors. Instead, the regulators of today provide precise values by which asset class prices and some macro-economic variables are expected to adversely move according to a shock scenario, according to a narrative that cannot make sense to bankers or economists! Moreover, they do not provide models for how to assess the whole scenario. Consequently, banks must assess balance sheet impacts on a line by line basis and not worry about whether the overall picture or its timeframe is realistic or if there are allowances for effective risk mitigations, merely the summing of capital losses (nominal, as if crystallised instantly in full).

The reason for this is that banks proved to be extremely reluctant to invest time and resources in building macro-models of their business and of their banking sectors, largely because they also wished strenuously to avoid accepting responsibility for what happens in  underlying macro-economies, nationally and internationally. They are suspected of being likely to game any degrees of freedom given to them to try and intelligently work it out for themselves. This way no one will learn anything new and really useful.

Stress Tests - A New Modeling Paradigm & a Pragmatic Approach

I have been reviewing the papers from a recent conference;-

The ESRB at 1

SUERF/Deutsche Bundesbank/IMFS Conference

& I think there is a crystallisation of a theme at that conference reflected in one particular presentation which articulates a narrative that we have been developing here on asymptotix in regard to Stress testing over the last 2 or 3 years.

Liquidity Risk - The Sharp End Issue of the Credit Crunch in 2008

Liquidity Risk is a confused topic (from a supervisory or B2 perspective)

because it has not been clear whether this is a risk type to be treated qualitatively or quantitatively through the development of the Basel II (B2) accords. In the initial months after the first Basel Accords were published most European regulators discussed the challenge of Liquidity Risk in qualitative terms. Latterly however the emphasis has been on the need for regulated financial institutions (FI) to stress test this aspect of Market Risk. This stress testing requirement demands that Liquidity Risk be treated quantitatively, from the perspective of a methodological approach to capturing how the FI’s exposure to this risk may fluctuate under extreme conditions.

SPAIN BANKS STRESS TESTS JUNE 2012

 

The Spanish authorities present the results of this excercise as two stress test reports (by Oliver Wyman & Roland Berger) & one independent assessment of those ST excercises by Promontory Group.

 

Further in the Spanish authorities statement is a presentation of the process for the detailed audit of the Spanish banking sector's overall exposure.

THAT ARMAGEDDON SUMMER OF 2010 Lessons for LTRO2 in 2012

SECRETS LIES & SMOKE AND MIRRORS

The Political Economy of LTRO

INTRODUCTION

It's LTRO[1] that I’m talking about this time! LTRO the latest version of “economic life support those” crackpot surgeons in the Central Banks and Treasuries of Europe have come up with. What is the issue with it? As LTRO2 approaches, to on the leap day (29/2/2012) I present a number of theses about LTRO;

1.      LTRO is a workaround for Crowding Out

2.      LTRO is executed via a process called 'Round Tripping' or known as a ‘Carry Trade’

3.      Hedge Funds are intrinsic to the success of LTRO

4.      This makes governments dependent upon Hedge Funds (& not just the banks)

5.      LTRO creates a cash balloon which props up the equity market

6.      LTRO is a high-risk central bank strategy which could deflate at a stroke

7.      Ironically the very Hedge Funds and Asset Managers who are intrinsic to the success of LTRO are already freaked out by the high risk nature of the policy,

IMF Global Financial Stability Report - September 2011: Europe bank's exposure to the eurozone debt crisis increased to €300bn

 

Europe bank's exposure to the eurozone debt crisis has increased to €300bn (£263bn).

Cumulative spillovers from high spread euro area sovereigns to the EU banking system - 300 bn euros

The epicenter of sovereign risk has been Greece, which generated the first of four waves of spillover to European banks. The analysis suggests that, first, spillovers on European bank exposures to the Greek sovereign have amounted to almost €60 billion (Figure 1.17). Second, as sovereign risks spread to other governments, the spillovers to banks have mounted. If the sovereign stresses in Ireland and Portugal are included, the total spillover rises to €80 billion. Third, the governments in Belgium, Italy, and Spain have also come under market pressure; incorporating credit risks from these sovereigns into the analysis further raises the total estimated spillover, to about €200 billion. Fourth, bank asset prices in the high-spread euro area have fallen in concert with sovereign stresses, leading to a rise in the credit risk of interbank exposures; including those exposures increases the total estimated spillover to €300 billion overall. Although these numbers are based on market assessments of credit risk, which may reflect a degree of overshooting, the underlying problems that they highlight are real.
