The Irish Case for LTV and LTI Caps on New Mortgage Lending

The Irish Central Bank discussion paper on macro-prudential policy tools published yesterday seems to be a trial balloon for possible caps on Loan-to-Income (LTI) and Loan-to-Value (LTV) ratios for new residential property mortgages in Ireland. The general theory behind imposing these limits is laid out clearly in that document; there is no reason to repeat it here. I want to discuss some notable features of the Irish environment which strengthen the case for these caps (but do not make the decision easy).

Problematic Calibration of the EU Banking Sector Stress Test for Ireland

The details for the calibration of the EU-wide bank stress test are now available. Looking only at Ireland, and only at one of the key variables in the stress test, the calibration looks problematic. It may be coincidental that the Irish adverse scenario has been badly chosen; it might be that all the other member countries have reasonable calibrations.  If the others are as problematic as in the Irish case, this is not a reliable EU banking sector stress test.

Under the adverse scenario, Irish property prices are assumed to suffer a cumulative three-year drop of 3.03%; equivalent to a decline of 1.02% each year for three years in a row. Over the period covered by CSO data, 2005-2013, Irish residential property prices had an annual sample volatility of 11.7%. This in turn implies (under reasonable assumptions) a three-year volatility of 20.27%. In risk analysis it is conventional analytical shorthand to measure adverse outcomes in “x-sigma” units defined as the outcome as a multiple of the standard deviation. For an adverse scenario calibration, the assumed outcome is usually roughly a two-sigma or three-sigma event. Using a four-sigma shock would not be unusual (due to fat tails in some probability distributions). The EBA has calibrated the adverse price shock as a 0.1492-sigma event. That is not credible as an adverse scenario in a stress test.

Keep in mind that the stress test is meant to reassure market participants that even in an adverse scenario the Irish banks are sound. This test reassures us that if property prices fall by as much as one percent a year over the next three years, the banks have enough capital. In the case of a two-percent fall, there are no promises.

As a caveat, this does not mean that the Irish banks need equity capital. They have already had a credible stress test (in 2011) and a big capital injection. Also, the Irish property market although very volatile has a maximum likelihood price change which is positive over the next three years. However the asset class also has considerable “downside” potential and continued high volatility. Conventionally, at least in the case of portfolio risk analysis, the unconditional mean of a stressed variable is set equal to zero for risk analysis purposes. The EBA has chosen to build in a big positive benchmark price rise for Irish property assets, and this is part of the reason that the adverse scenario is unacceptably mild. In any case, this calibration is extremely mild as an adverse scenario and not reassuring for the EU-wide test.

Ending the Sean FitzPatrick Myth

16th April 2014: Sean FitzPatrick has been found not guilty of all charges relating to the Maple 10 transaction. First the judge (for some of the charges) and then the jury (for the remaining charges) examined the evidence carefully, and declared him not guilty. The Maple 10 scheme was truly outrageous, but there is no reason to second-guess the verdicts as given.

From a broader perspective, these not-guilty verdicts might encourage a deeper understanding and better public response to the Irish credit bubble and financial collapse. It is a myth that Sean FitzPatrick caused the Irish financial collapse. Sean FitzPatrick was a major character in the Irish credit bubble, but not a fundamental cause. The collapse is better explained by the extremely “light-touch” financial regulatory system which was deliberately chosen by the democratically elected government of the Irish state, and to a lesser degree by the deeply-flawed Euro currency system chosen by member states. Over the short term, the Irish public benefitted handsomely from both the flawed Euro currency system and the very flawed light-touch Irish financial regulatory system. The Irish electorate was keenly enthusiastic for both.

The Maple Ten scheme was an outrageous transaction whose sole purpose was to unwind another outrageous transaction – the accumulation of a disguised 29% ownership of Anglo Irish Bank by Sean Quinn using contracts for difference (CFD). CFD’s are only legal in some countries, are a naturally toxic trading vehicle, and evade corporate governance rules by disguising true share ownership. Ireland during the boom was a world leader in the use of CFD’s, and Sean Quinn’s disguised 29% ownership position using CFD’s was particularly outrageous.  The Irish financial regulator was simultaneously monitoring (or not monitoring) two very large and very dubious financial transactions in a relatively tiny domestic financial system. To lose track of one large, dubious financial scandal may be regarded as a misfortune, to lose track of two looks like carelessness.

During the bubble period macro-prudential risk regulation by the Irish Central Bank was also (with hindsight) very poor.

The fundamental causes of the Irish financial collapse were two flawed systems – a flawed Euro monetary system and a very flawed Irish financial regulatory system. Both of these systems were built up in broad view and with enthusiastic public support.

Aviation policy ‘week’ this November

This year’s European Aviation Conference takes place at the University of St Gallen, Switzerland on 14 and 15 November. Programme, speakers, booking details and venue are at www.eac-conference.com.

Feedback after last year’s event indicated a greater preference for active debate, so almost the entire first day this year is devoted to a moderated discussion between ten invited advocates and critics of airport price regulation. And the 2013 Martin Kunz Memorial Lecture is to be given by the person credited with devising modern price cap regulation, Professor Stephen Littlechild.

HAC 2013 is preceded on Wednesday 13 November by a workshop of the German aviation research society (GARS); the call for papers is here: www.garsonline.de.

Unsated wonks can devote the entire week to aviation policy; IATA holds a two-day discussion on evaluating the economic effects of air transport on Monday and Tuesday 11-12 November in Geneva. Details on the GARS website given above.

Strategic Irish Mortgage Arrears: The Smoking Gun

My colleague Tom Flavin and I are preparing a paper for the Dublin Economic Workshop on the financial characteristics of Irish Mortgage defaults. The analysis relies on a donation of anonymized data on mortgage arrears from Permanent TSB and we are grateful to them for their assistance. Tom will give a fuller account of our data analysis at the conference; this blog entry highlights some of the strong evidence for a very substantial proportion of strategic arrears in Irish mortgage arrears.
