Current Market Environment in Bangladesh
- Recognized key socio-economic impacts (growth, private sector, social safety, wealth and savings, etc.)
- Sizeable part of the broader financial sector (market-base integration, liberalization, stabilizer or leveraging role)
- Room for expansion & social penetration (housing finance constrains urban development)
- Diversified primary market: about 10 lenders, volume becoming significant (Tk 75 billion 2003), 3 dynamic NBFIs that strongly need new capital sources
- New legal framework anticipated for 2005
Existing Portfolios Unsuitable for Securitization
- High NPLs (except for the 3 specialized lenders)
- Rates adjustable at lender discretion incompatible with loan sales
- Equitable mortgages prevent securitization for operational reasons (lenders keep physical titles)
- Market infrastructure conditions fall short
- Property/security right registration still largely unreliable
- Efficacy of new, extrajudicial foreclosure procedure remains to be tested
- Securitization started in India in similar environment
- consequence has been high transaction costs including oversized anti-default buffers.
- Also, market restricted to specialized lenders with proven expertise in managing credit risk
- Likely to be same in Bangladesh (only 3 specialists will be acceptable for investors, other lenders must first gain recognition in their risk management capacity)
Mortgage Market May Not Develop Spontaneously
- Uncertainty as to investors’ protection against credit or prepayment risks :
- inherent to infant markets, but may be dissuasive
- Absence of “market” for credit risk (insurers, guarantors, low grade investors): a major stumbling block for securitization
- Cannot skip basics: legal, regulatory, collateral, macro, standards, competition, etc. pre-conditions to be analyzed
- No housing finance miracle if inadequate supply of low-middle-income housing and of titled land
- Dual challenge: (1) manage credit and market risks (2) adequate accessibility and affordability to homebuyers
- Legal frameworks for financial instruments:
- Adjustment of the bankruptcy law/true sale conditions
- Fiduciary arrangements
- Robust market infrastructure
Government Role in Market Development
- No direct lending but regulator, market catalyst, provider of infrastructure & subsidies (complex)
- Relatively low depth in financially developed systems sometimes due to large share of public housing
- France, Chile
- Conversely, depth (or high growth) is sometimes related to large government support
- USA: large interest tax deductibility (0.6% GDP), govt backing of FHA/VA (15% market), GSE implicit guarantee (over 50% market)
- Netherlands: total interest deductibility, tax exemption on savings plans, government backed guarantee fund
- Hungary: subsidies on mortgage bond financed loans, tax exemption for mortgage bond holders, tax break for mortgagors on top of direct demand subsidies
Inducing Market Development
- Banks may be reluctant to develop housing finance, or act as an oligopoly: priority to high margins over high volumes.
- How to jump start a market or overcome a market failure?
1. - Credit direction, margin control: counterproductive, likely to be damaging for the supply of finance in the long run
> Need of a “ market maker” or market engine
2. - State Housing Banks: a frequent temptation, only exceptionally successful (National Housing Bank in Thailand, BancoEstado in Chile)
- Access to privileged funding (MOF, Central Bank) :
- Kills the commercial supply
- Does not foster the development of sustainable long term capital
- Often benefits to ill- targeted groups
- Permissive lending and high NPL rate
- Major governance issues
Examples of Government Interventions
- Provision of funding (Chile 1977-1980)
- Provision of credit enhancement (Mexican SHF)
- Creation of second tier facilities with a catalytic purpose (ex. of successes : Cagamas, Jordanian JMRC)
- Assumption of macro-economic risks (wage/price index swap in Mexico)
- Incentives to the market liquidity of securities (repo facility in Colombia)
Why capital markets are important for mortgage lending
- Long loan amortization periods (key of affordability) + fixed interest rates (desirable to pre-set them at least for a few years for credit risk considerations) > dangerous balance sheet mismatches can develop (multiple experiences)
- Specially risky to rely entirely on deposits if unstable deposit bases and if no available hedging instruments (swaps…)
- Government funding to remedy the lack of long term capital generates more problems (unavoidable rationing, interest distortions, ill-targeted benefits…) that it solves
Investors require credit enhancement because of long maturities:
- Central liquidity facilities (Cagamas in Malaysia, JMRC in Jordan). Dedicated to provision of funds to lenders, with pledge on loan portfolios, financed through bond issues
- Covered bonds (Europe –including UK now-, Latin America): debt of lender collateralized by mortgage portfolios meeting a few, regulated quality norms, bondholders have privileged status in case of bankruptcy
- Securitization :
- Ownership of loan portfolio transferred, investors insulated from deterioration of lender’s credit (bankruptcy remote)
- Credit risk on loans is filtered, investors only exposed to residual risk after the “waterfall” effect of successive cushioning devices, including external credit enhancement
- Liquidity and interest rate – especially prepayment risk- risks are shifted to investors
Coverage of incremental credit risk through insurance
- US (FHA, historical model), Canada (CMHC), Continental Europe, Mexico (SFH), Baltic states, Kazahkstan
- Criteria: - High LTV (first buyers in particular)
- Income or price limits
- Unblemished credit history (FHA)
- Coverage: 70% to 100%
- Government backing - typically: combination actuarial reserves + last resort support (catastrophic risk)
- Cost: typically borne by the borrowers, but lowered by the government backstop
- Issue in early stages of a market: few data available, bigger risk of adverse selection and moral hazard -- pricing difficult, high cost
Examples of Mortgage Insurance
1. Mortgage substitute (for lenders)
For lenders, outsourcing to remedy mortgage deficiencies
(Foreclosure often a lengthy, costly and uncertain process)
Examples: Algeria (SGCI), France (Credit-logement), Jordan (JLGC), Slovenia, Mali, West bank Gaza (PMIF)
- Purpose : Transfer, but little mitigation of risks (The source of inefficiency remains, possible benefits from mutualization)
- Loan criteria : same as lenders, or even more restrictive (LTV < x% )
- Coverage : anticipation of forced sale proceeds, loss sharing provision
- Cost borne by borrowers or lenders
Often high cost for the value. Specific conditions to be successful
2. Mortgage supplement (higher risk)
Loans with increased expected losses -Typically: higher-than-normal
LTV,an indicator of probability of default as well as of severity of loss
Examples : USA, UK, Canada, Australia,Thailand (on going)
- Purpose:
    - efficiency, risk measurement (mutualization, geographical diversification, modeling)
    - secondary mortgage market requirements
                   (Fannie/Freddie in the USA)
Criteria : insurance required if LTV > y% (75%- 80% typically)
- Coverage : first loss –20% to 30% typically, excludes catastrophic losses
- Cost borne by the borrower
MBS Require Sophisticated Markets
- Valuation is major issue, MBS are complex securities that require investor skills & above all information. A robust historical series & public information regarding portfolio past & prepayment behaviour is required.
- MBS also require an appropriate infrastructure (e.g. transparency obligation, dissemination vehicles) to enable sound pricing procedures.
- Securitization of mortgages more difficult than other assets (e.g. IPDC securitization). Uncertainty in the value factors translates into high premium, making transactions costly.
- Although mortgage bonds and mortgage backed securities look similar, they have distinct characteristics
- Outright vs contingent transfer of credit risk
- Transfer of financial risk to capital market vs A/L management by financial intermediaries
- Standardized loans vs standardized securities
Mortgage Related Securities
1. Direct goal: hedging financial intermediaries' risks
2. Indirect impact:
- Promote primary market discipline
Investors’ confidence in the primary market required (lending standards, efficiency of collateral, quality of recovery)
… sometimes with the help of regulation: special foreclosure procedures for loans refinanced by capital market (Chile, Poland, Argentina), lending quality norms (mortgage bonds)
- Foster capital market development
Often, institutional savings lacks investment vehicles (-> low-return, short term or foreign currency investments)
An archetypical experience: Chile (parallel take off of reactivated mortgage bonds and newly created pension funds after 1980)
Mortgage Bonds
- A decentralized, covered debt instrument: double security level
- General obligation of the issuer
- Lien on loan portfolio in case of insolvency (exception to bankruptcy law)
- Regulated portfolio quality (typically: 60% to 75% LTV)
- A regional instrument: continental Europe (20% of mortgage loans) and Latin America, but ongoing diversification:
- geographical : European transition economies (Poland, Hungary, Bulgaria, Czech Republic…), UK, Peru, Colombia
- Linked to technical strengthening (structured finance methods):
- Modernized cover principle (Net Present Value)
- Strengthened bankruptcy privilege: asset ringfencing, explicit exclusion from bankruptcy estate, non-acceleration principle, prior claim over other asset instead of OC…
MBS are most suited to:
- Large countries or zones where credit risk diversification has much sense (ex.: India, Mexico)
- Lenders whose size, specialization or history hamper their capacity to manage financial risks
- Lenders with scarce capital base or insufficient rating
- Expensive, at least initially (agency risk, illiquidity premium, credit enhancement based on worst case scenarios), but cost to be balanced with benefits (rating upgrade, economy of capital, transfer of risks)
- A tool that needs a long maturation period (data series for valuation, availability of credit risk buyers)
- Securitization in emerging countries tends to start with ABS rather than MBS, contrarily to the historical path in developed economies
Mortgaje Bonds are most suited to:
- Lenders of fairly good standing
- Lenders with nationwide networks (credit risk diversification)
- Market liquidity enhancement
- Cheaper than MBS, - simple, more liquid, regulation vs expensive risk cushions
- No deterioration of the portfolio average quality
- Prepayment risk is a challenge
- If bonds can be callable: possible inefficiencies (valuation of the financial option disconnected from the actual prepayment rates)
- If prepayment risk kept by the lender: diversified financial institutions (capable of internal hedging) more appropriate issuers of MB than specialized institutions.
- (Another difference with the history of developed economies)
Mortgage Liquidity Facilities
Centralized refinancing institutions that pool the funding requirements of lenders and issue bonds
Examples: Malaysia (Cagamas Berhad), Jordan (JMRC), Algeria (SRH), USA (FHLB system)
Lend (with overcollateralization), or buy with recourse: bring long term liquidity, do not take over credit risks
Typically owned by their users, sometimes with government/Central Bank participation or support (USA)
Specialized, low cost intermediaries
Frequently catalyst effect on the primary market
Drawback: an additional layer of intermediation
Role for Government
- Too often: costly, inefficient and inequitable methods
- Direct provision of housing by the government
- Administratively set rates (kill the finance supply)
- Misuse of provident funds
- Allocation of land with a social opportunity cost that can be huge but ignored in the absence of proper land market
- Assistance schemes need to be:
- Explicit (budgeted)
- Leveraged by private finance
- Non-distortive
- An incentive to more savings, more lending,better housing supply
Government has an important role to play – but the path between market promotion and distortion is narrow:
1. Are there real limitations to private market solutions (not just a demand to artificially lower the cost of funds)?
2. Is there a risk of price distortion that would kill the increase of finance supply?
3. Can public institutions efficiently manage guarantee or funding programs?
4. Privatization strategy for when market has matured & need for incentives have disappeared
5. Do government guarantees or resources induce market forces to cater to underserved households?
6. Market development can take years. Creating a framework does not equate creating a market.
7. The development path does not necessarily replicate the history of more advanced economies
