New York Fed president Tim Geithner, who hasn't been shy about warning about
financial risks from financial market innovation, doesn't seem too concerned
that problems in the subprime mortgage market will spread and cause wider
disruptions. Here's part of a longer speech:
Credit Markets Innovations and Their Implications, by Timothy Geithner, NY Fed
President: ...The latest wave of credit market innovations has elicited some concerns about
their implications for the stability of the financial system, concerns similar
to those associated with earlier periods of rapid change in financial markets.
Will the most recent credit market innovations amplify credit cycles,
contributing to "excessive" lending in times of relative stability, and then
magnify the contraction in credit that follows? Will they introduce greater
volatility in financial markets? Will they create greater risk of systemic
financial crisis?
These concerns have been heightened in some quarters by the problems
currently being experienced in the subprime mortgage sector. It will take some
time before the full implications are understood and the full impact can be
assessed. As of now, though, there are few signs that the disruptions in this
one sector of the credit markets will have a lasting impact on credit markets as
a whole.
Indeed, economic theory and recent practical experience offer some
reassurance against both these specific concerns and more general worries about
the implications of credit market innovations for the performance of the
financial system. ...
There are ... compelling arguments in favor of a generally positive
assessment of the consequences of innovation. Does experience provide support
for these arguments, or are these changes too new for us to know? ...
We are now well into the third decade of experience with the consequences of
these earlier innovations, and this history offers some useful lessons for
evaluating the probable impact of the latest changes in credit markets.
The ease with which the U.S. financial system absorbed the substantial scale
of corporate defaults that peaked in recent years in 2002 provides some support
for the argument that broader and deeper capital markets make the system more
resilient. In general, there does not seem to be strong empirical support for
the proposition that derivatives increase volatility in financial markets. ...
Credit market innovation does not appear to have resulted in a large increase
in leverage in the corporate sector, as some had feared. ...
Default rates do not appear to have risen, nor recovery rates fallen as these
credit innovations have spread, despite concerns they might lead to excess
lending, the mis-pricing of credit risk and more messy and more complicated
workouts, resulting from the greater diffusion of the investor base.
And although the sources of the broad moderation in GDP volatility observed
in the United States over the past two decades are still the subject of debate,
the fact that this moderation occurred during a period of extensive innovation
in credit and other financial markets should provide some comfort for those who
expected the opposite.
Innovations in credit markets are inevitably accompanied by challenges.
Indeed, the history of innovation in financial markets provides many examples of
periods of rapid change accompanied by fraud and abuse, by challenges in
assessing value and risk, by concerns about the adequacy of investor and
consumer protection, and by unexpected behavior of prices, defaults and
correlations. To some degree, these types of problems are the inevitable
consequence of change and innovation.
Although recent experience as well as theory provide some reassurance..., these judgments require qualification.
Some aspects of this latest wave of innovation are different in
substance ... from their predecessors. ... [B]road changes in financial markets
may have contributed to a system where the probability of a major crisis seems
likely to be lower, but the losses associated with such a crisis may be greater
or harder to mitigate.
What should policymakers to do mitigate these risks?
We cannot turn back the clock on innovation or reverse the increase in
complexity around risk management. We do not have the capacity to monitor or
control concentrations of leverage or risk outside the banking system. We cannot
identify the likely sources of future stress to the system, and act preemptively
to diffuse them.
The most productive focus of policy attention has to be on improving the
shock absorbers in the core of the financial system, in terms of capital and
liquidity relative to risk and the robustness of the infrastructure. ...
The Federal Reserve is actively involved in a range of efforts... The stronger these shock absorbers, the more resilient markets will be in the
face of future shocks, and the more confident we can be that banks will be a
source of strength and of liquidity to markets in periods of stress and that the
financial system will contribute to improved economic performance over time.
