A rise in General-Purpose Loan Usage for Residential Borrowers

After the LTV cap increases from 75% to 80% at the end of September 2016, we

  • bserve a rise in the median and total GP borrowing for new home owners.

Figure 1: Median general-purpose loans (thousand TL) by residential borrowers.

What explains this increase after the policy easing?

Questions

What is the impact of the introduction of restrictive LTV caps on bank lending behavior? ◮ Introducing a cap of 75% (2011) should affect banks’ lending and risk

  • ptimization.

◮ ”Unmet lending appetite” redistributed among other retail? Commercial? ◮ ”Unmet risk appetite” triggers riskier lending behavior? What is the impact of an easing change in LTV caps on non-residential borrowing by constrained home owners? ◮ Increasing the cap from 75% to 80% (2016) should affect borrowers’ optimization ◮ Lower the additional borrowing?

Contributions

◮ Use credit register data and appraisal reports

◮ Universal coverage on housing loans at the individual-loan level ◮ In a large emerging economy

◮ Policy changes were exogenous shocks ◮ Bank Assets and Risk Preferences: Contrast exposed and non-exposed banks in terms of retail, commercial lending and risk preferences. ◮ Residential Borrowers’ Additional Loan Use: Contrast non-residential borrowing of LTV cap constrained borrowers before and after the policy change ◮ Isolating demand and supply side effects

Preview of Results - Lending and Risk Taking

Introduction : High exposure banks ◮ Reduce residential loan amounts, ◮ Increase GPloans... ◮ ...and they do so for new residential borrowers ”unmet lending/risk appetite” ◮ Increase commercial loans... ◮ ...esp for riskier firms ”unmet risk appetite” Expansion : Banks with average LTV closer to 75% ◮ Increase residential and GPloans esp for residential borrowers ”credit spill-over” ◮ They have lower commercial loan outcomes than banks farther away from the limit but the effect is for a short period

Preview of Results - Easing

Higher LTV cap increases access to residential borrowing - should lower the need for additional funds But we see that average and total GP borrowing has increased after the easing policy LTV cap constrained buyers are taking out more non-residential loans than unconstrained : ”credit spillover”. LTV cap constrained buyers after the change are taking out more non-residential loans than before : ”flight to quality”?

Mechanism

Demand Side Factors Introduction of a cap makes some buyers credit constrained. Some buyers are discouraged from entering the housing market altogether. Others will enter purchase contracts: ◮ Will need additional funds to cover expenses associated with a new home.

◮ These purchases usually occur after the home purchase.

◮ May still need additional funds to cover the cost of the required downpayment.

◮ These additional funds will be needed leading up to the home purchase.

Baziki & C ¸apacıo˘ glu (CBRT) LTV Caps and Additional Loans 11 / 52

slide-12
SLIDE 12

Mechanism

Supply Side Factors Introduction of a cap frees up funds Banks may chose to reallocate these funds within their loan portfolio ◮ Either by extending residential credit to constrained applicants the bank would

  • therwise not be in business with,

◮ Or by extending a non-residential loan to residential loan applicants which would result in a higher leverage ratio per the value of the house, ◮ Or switching sides completely and increase commercial lending. Either path, the bank engages in riskier lending behavior.

Previous Literature : Macroprudential Policies

Cross-country studies: Kuttner and Shim (2016), Cerruti et al. (2015), and Lim et al. (2011) Micro-level data: Jim´ enez et al. (2012) and Igan and Kang (2012) ◮ Most macroprudential policies are linked to lower credit growth ◮ Focus on macroprudential policies and house prices or financial cycles Claessens et al. (2014) find policies targeting consumers help bank balance sheets through lower leverage. ◮ But lower leverage in housing loans does not necessarily mean lower risk or leverage on the consumer side ◮ Riksbanken (2012) announced an increase in unsecured loans after the introduction of LTV cap ◮ Furthermore, riskier lending on the commercial side would exacerbate the situation.

SLIDE 14

Previous Literature : LTV and Income Related Caps

Hallissey et al. (2014) LTV and LTI together lower credit risk on new lending ◮ Loan-level data from 3 banks ◮ Sharp increases in losses on defaulted loans for LTV > 85%. Jung and Lee (2017) find DTI better at stabilizing HP than LTV. ◮ District-level data on transactions ◮ LTV alone is subject to higher LGD Lee (2012) stable NPL on housing despite lower HP due to LTV and DSTI. J´ acome and Mitra (2015) LTV and DTI together lower credit growth (but not always HP). IMF Staff Guidelines (2014) imply that DSTI increase the effectiveness of LTV as they limit the use of unsecured loans to meet the downpayment limit.

◮ Purchasing a home is a long term investment, and requires some planning.

Summary of Results - Introduction

Introduction of the LTV cap ◮ Reduces residential loans in favor of higher uncollateralized lending to new residential borowers, ◮ And higher riskier lending on the commercial side. ”unmet lending/risk appetite” ◮ Results confirm that there is ”spillover” from housing to non-residential loans, increasingly so for the exposed banks.

Summary of Results - Easing

◮ Being constrained by the LTV ratio cap increases GP loans by 5 to 6 thousand TL. ◮ The added premium of being constrained by the LTV ratio cap after the regime change is an additional 4 to 6 thousand TL.

◮ per-capita GP loans are at 12 thousand TL. ◮ Surprising result since a larger LTV ratio cap should reduce the need for additional loans.

◮ Results confirm that there is ”spillover” from housing to non-residential loans, increasingly so for the credit constrained. ◮ And that as the cap is increased, borrowers are switching to more expensive homes, increasing demand for credit.

◮ Share of lending above cutoff over total lending

Conclusion

◮ With LTV, credit constrained individuals have a higher likelihood to top off their residential loans with other means of borrowing. ◮ LTV may also result in riskier bank balance sheets through increased riskier commercial lending (2011) or uncollateralized loans (2016). ◮ LTV caps alone do not provide sufficient deterrence from residential leverage for households. ◮ Implications for credit availability, transmission, asset decomposition, and optimal risk weight design. ◮ Best practice may have to introduce income related limits.

Methodology - OLS Regressions

◮ Finally, we investigate if additional GP lending is motivated by housing LTV ratios from January 2011-April 2017 with the following specification for individual-credit i, for bank b, and time t: GPloans HousePrice ibt =αi + βLTVit + ζPersonObsit + ωAftert + θLTVit ∗ Aftert + ρPersonObsit ∗ Aftert + γBankObsbt + ηMacroObst + εibt. (7)

◮ PersonObsit : in-house credit rating, number of credit cards, and other outstanding debt. ◮ BankObsbt : capital, liquidity, NPL, ROA, loan-to-asset ratios, and log real assets. ◮ MacroObst : interest rates, IPI, CPI, REER. ◮ LTVit ∗ Aftert accounts for the way LTV levels affect the dependent variable differently after the policy change. ◮ PersonObsit ∗ Aftert allows for different returns to personal observables.
