The Volatility Laboratory or V-LAB is a public website
with a wide range of risk measures that are updated
daily.
The site is a laboratory to determine the accuracy and
reliability of cutting edge statistical models of financial
risk.
The site is designed to bring new academic
developments to practitioners and regulators in a
timely way.
The Volatility Institute is supported by generous
funding from the Sloan Foundation, Banque de France,
Armellino Foundation, Deutsche Bank, BlackRock, and
our collaborators UNSW and Universite de Lausanne

Or Google vlab
There are four main regions on V-LAB
Volatility
 Correlation
 Systemic Risk
 Long Run Risk

Lets take a look at each before turning to
systemic risk.

VaR is the 1% quantile of returns for some asset
one day in the future. It is a very widely used
measure of risk but is clearly a short run
measure of risk.
What is the VaR one month or one year from
now? How much can some asset decline in a
year?
Measuring “the risk that the risk can change”
Use GARCH and options to forecast quantiles.

In the global financial crisis of 2007-2009, we
learned that failure of the financial system
could have massive effects on the real
economy, potentially for years to come.
The sovereign debt crisis in Europe is a
reminder that even though the causes may
appear different, financial failure has real
effects.
How can we forsee and prevent these events?

We saw that the Lehman bankruptcy began the
worst episode of the global financial crisis. But
it coincided with deep distress at FANNY and
FREDDIE, Citi, Bank of America, Merrill
Lynch, Goldman Sachs, Morgan Stanley, AIG,
WAMU, Wachovia, and many more.
Lehman was not a domino – this was a tsunami.
Weakness of the financial sector as a whole is
the most important determinant of a financial
crisis. It is not enough that one bank is
undercapitalized.

How much capital would a financial institution need to raise
in order to function normally if we have another financial
crisis?
We measure this econometrically based on market data
on equities and balance sheet data on liabilities. We
update weekly on V-LAB for US and Global financial
firms. We call this SRISK.
Principle investigators: Viral Acharya, Matt Richardson and me at the
Volatility Institute at NYU’s Stern School. Collaboration with HEC Lausanne
and the Institute for Global Finance at University of New South Wales.

Fed released its 2014 CCAR on Thursday
Minimum Tier 1 Capital Leverage Ratio is the
minimum of book equity over Q4 2013-Q4 2015
under the most severe adverse scenario
Compare with SRISK as of Oct 31, 2013 and with
the stressed leverage ratio implied by V-LAB. What
capital ratio would a firm have after V-LAB stress.

Drop non-bank financial firms, firms without publicly traded
equity and banks not included by FED to get 21 firms.

All rank and cardinal correlations are .6 or .7.
