Does Greenspan Favor Adjustable Rate Mortgages?
March 8, 2004
"I wonder what you thought of Fed Chairman Greenspan’s statements that
mortgage borrowers could save a lot of money if they opted for
adjustable rate mortgages (ARMs) rather than fixed-rate mortgages
(FRMs)?"
While the Chairman’s remarks were carefully hedged, he certainly seemed
intent on conveying the view that more borrowers should select ARMs. He
made two arguments, neither of which withstand close scrutiny.
FRM borrowers could have saved a ton of money over the last decade had
they chosen ARMs instead. This is certainly true but has no implications
at all for what borrowers should do now. Interest rates declined during
much of the previous decade, but could rise during the next decade; we
just don’t know.
My last mortgage, an FRM, was taken out in 1978. Because mortgage rates
roughly doubled over the 3 years that followed, I saved a ton of money
compared to those who took ARMs at the same time. I took the FRM because
I was cautious, not because I was smart.
The rate difference between an FRM and an ARM can be properly viewed as
an insurance premium that buys protection against future rate increases.
Sometimes you need the insurance, sometimes you don’t, but you don’t
know until the game is over – just as you don’t know if you are going to
need fire insurance on your house. If you don’t have a fire, you don’t
think of the premiums you paid as wasted. They bought you peace of mind,
which is what the rate premium on an FRM buys you.
Borrowers in the US have a much stronger [irrational?] preference for
the certainty of fixed mortgage payments than borrowers in any other
country. It is a fact that FRMs with long terms are a standard mortgage
only in the US. But does this reflect some irrational quirk among US
borrowers that ought to be discouraged? I think not.
There are two major reasons why most borrowers in the US have preferred
FRMs. One is that the rate premium that they have to pay for an FRM, as
compared to an ARM, is much smaller than it would be anywhere else in
the world because it is subsidized. Fannie Mae and Freddie Mac, which
can borrow at very low rates because they are Government sponsored
enterprises, purchase a large share of all new FRMs. In the US, FRMs are
a bargain. FRMs don’t exist elsewhere largely because the rate premium
would be too large for borrowers to swallow.
The second reason borrowers in the US have preferred FRMs is that ARMs
in the US are incredibly complicated, few borrowers understand them, and
mandatory disclosures under Truth in Lending don’t help.
Most ARMs abroad allow lenders to adjust the rate at their own
discretion. This has obvious drawbacks, but it does have the virtue of
simplicity. In contrast, ARMs in the US use a mechanical indexing
procedure for making rate adjustments, which eliminates lender
discretion but makes the instrument extremely complicated.
Given their complexities, the acceptability of ARMs could be
substantially enhanced by good disclosure rules. Such rules would be
limited to critically important information and presented clearly.
The most critical information for most borrowers is 1) What would happen
to the interest rate and the monthly payment if the interest rate index
doesn’t change; and 2) What would happen if the loan rate rises to the
maximum permitted by the loan contract?
Instead, Truth in Lending requires lenders to provide ARM borrowers with
a check-list of ARM features that is meaningless to most of them.
Lenders can use their own formats in providing this information, which
vary from lender to lender, and there are no requirements for clarity.
Some that I have read are incomprehensible. In addition, borrowers may
get a useless example of how their mortgage would have worked had it
been written 15 years earlier.
If Mr. Greenspan really would like to see ARMs comprising a larger share
of total mortgages in the US, he is well positioned to do something
about it beyond just talk. The Federal Reserve administers Truth in
Lending, and while its discretion to change it is limited by Congress,
it carries a lot of weight with Congress. This would require a
willingness to spend political capital on a consumer protection issue,
something that the Fed historically has been reluctant to do.
