prices comes from the Fannie Mae’s 2001 Annual Report where its CEO Franklin Raines
stated: “Housing is a safe, leveraged investment – the only leveraged investment available
to most families – and it is one of the best returning investment to make. Home will
continue to appreciate in value. Home values are expected to rise even faster in this decade
than in the 1990’s”. Less than a decade later the reality brought the excessive optimism
down to earth.
Interestingly there was a minority, who claimed that housing market may be subject to
speculative bubbles as any other market, especially after Japanese lesson ended up with
lost generation of young overleveraged people who need to pay off their mortgages
substantially exceeding current property value after market collapse. It goes without saying
that these voices remained minority for quite some time.
In order to slightly better understand the systemic foundation for the housing bubble let us
try to look at the home finance evolution in the US. Historically the most popular housing
finance scheme was fixed 30-year mortgage with no prepayment penalties. It means that
the borrower was obliged to pay fixed monthly installments over the life of the loan.
Absence of prepayment fees allowed the borrower to refinance its obligations when
interest rate went down, thus reducing monthly costs of servicing the debt. The
abovementioned characteristics combined with natural cyclicality of the interest rate and
inflation allowed homeowners on an aggregate basis grow out of the debt when their salary
rose.
From the perspective of Savings & Loan Associations popular at a time the situation was
not that positive. S&Ls allowed for asset-liability mismatch on their balance sheets
financing long-term mortgages with short-term funding. When short term interest rates
declined clients refinanced, but when rates increased clients were not entitled to increase
payments. The negative spread between mortgage rates and costs of deposits led to the
collapse of almost half of S&Ls by the end of 80-ties. In order to prevent run o S&L’s the
government insured deposits and created dedicated institutions to buy S&L assets.
The collapse of S&L system fueled development of securitization and increased the role of
government-sponsored entities (GSE). These entities were created for the purpose of
buying and pooling mortgaged loans on the asset side and at the same time issuing
mortgage-backed securities (MBS) on their liabilities side. Very important characteristic of
such structure was the guarantee provided by the GSE to the investors. Given their
government-backed status investors assumed GSEs to be close to risk-free and the only
risk that they were buying was the prepayment risk.
