Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 1 / 52
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, weobserve 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?Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 2 / 52
Questions
What is the impact of the introduction of restrictive LTV caps on bank lendingbehavior?
I Introducing a cap of 75% (2011) should affect banks’ lending and riskoptimization.
I ”Unmet lending appetite” redistributed among other retail? Commercial?
I ”Unmet risk appetite” triggers riskier lending behavior?
What is the impact of an easing change in LTV caps on non-residential borrowing byconstrained home owners?
I Increasing the cap from 75% to 80% (2016) should affect borrowers’ optimization
I Lower the additional borrowing?

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

Preview of Results - Easing
Higher LTV cap increases access to residential borrowing - should lower the need foradditional 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 thanunconstrained : ”credit spillover”.
LTV cap constrained buyers after the change are taking out more non-residential loansthan before : ”flight to quality”?
Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 10 / 52
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:
I Will need additional funds to cover expenses associated with a new home.I These purchases usually occur after the home purchase.
I May still need additional funds to cover the cost of the required downpayment.I These additional funds will be needed leading up to the home purchase.
Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 11 / 52
Mechanism
Supply Side Factors
Introduction of a cap frees up funds
Banks may chose to reallocate these funds within their loan portfolio
I Either by extending residential credit to constrained applicants the bank wouldotherwise not be in business with,
I Or by extending a non-residential loan to residential loan applicants which wouldresult in a higher leverage ratio per the value of the house,
I 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: Jimenez et al. (2012) and Igan and Kang (2012)
I Most macroprudential policies are linked to lower credit growthI Focus on macroprudential policies and house prices or financial cycles
Claessens et al. (2014) find policies targeting consumers help bank balance sheetsthrough lower leverage.
I But lower leverage in housing loans does not necessarily mean lower risk orleverage on the consumer side
I Riksbanken (2012) announced an increase in unsecured loans after theintroduction of LTV cap
I Furthermore, riskier lending on the commercial side would exacerbate thesituation.
Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 13 / 52
Previous Literature : LTV and Income Related Caps
Hallissey et al. (2014) LTV and LTI together lower credit risk on new lending
I Loan-level data from 3 banksI Sharp increases in losses on defaulted loans for LTV > 85%.
Jung and Lee (2017) find DTI better at stabilizing HP than LTV.
I District-level data on transactionsI LTV alone is subject to higher LGD
Lee (2012) stable NPL on housing despite lower HP due to LTV and DSTI.
Jacome and Mitra (2015) LTV and DTI together lower credit growth (but not alwaysHP).
IMF Staff Guidelines (2014) imply that DSTI increase the effectiveness of LTV as theylimit the use of unsecured loans to meet the downpayment limit.

Summary of Results - Introduction
Introduction of the LTV cap
I Reduces residential loans in favor of higher uncollateralized lending to newresidential borowers,
I And higher riskier lending on the commercial side. ”unmet lending/risk appetite”
I Results confirm that there is ”spillover” from housing to non-residential loans,increasingly so for the exposed banks.
Baziki & Capacıoglu (CBRT) LTV Caps and Additional Loans 35 / 52
Summary of Results - Easing
I Being constrained by the LTV ratio cap increases GP loans by 5 to 6 thousand TL.
I The added premium of being constrained by the LTV ratio cap after the regimechange is an additional 4 to 6 thousand TL.
I per-capita GP loans are at 12 thousand TL.I Surprising result since a larger LTV ratio cap should reduce the need for additional
loans.
I Results confirm that there is ”spillover” from housing to non-residential loans,increasingly so for the credit constrained.
I And that as the cap is increased, borrowers are switching to more expensivehomes, increasing demand for credit.

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

I Finally, we investigate if additional GP lending is motivated by housing LTV ratiosfrom January 2011-April 2017 with the following specification for individual-crediti , for bank b, and time t:
GPloansHousePrice ibt
=αi + βLTVit + ζPersonObsit + ωAftert + θLTVit ∗ Aftert
+ ρPersonObsit ∗ Aftert + γBankObsbt + ηMacroObst + εibt .(7)
I PersonObsit : in-house credit rating, number of credit cards, and other outstandingdebt.
I BankObsbt : capital, liquidity, NPL, ROA, loan-to-asset ratios, and log real assets.I MacroObst : interest rates, IPI, CPI, REER.I LTVit ∗ Aftert accounts for the way LTV levels affect the dependent variable
differently after the policy change.I PersonObsit ∗ Aftert allows for different returns to personal observables.
