Amplification mechanisms
2009
Background - macroeconomics
Macroeconomic imbalances
Fairly high economic growth at world
level, yet low inflation partly due to cheap
imports from low-cost countries
Central banks set low interest rates in 20022005
Economic growth and low interest rates
High growth in asset values
”Search for yield”
2009
High saving in China, Japan, Germany and oil
exporting countries
High borrowing in the U.S, UK, Spain, etc
House prices
2009
Background – financial markets
Extensive changes in financial markets last
20-30 years
Advantages
Easier to borrow, better funding of investments
Broader spectre of assets, diversification
Increased efficiency and profitability
2009
Institutional changes (e.g. hedge funds, private
equity funds)
Deregulation – removal of artificial barriers
Technology – increased access to information,
communication, computer power, financial
innovation
Strong profit motives and incentive based
remuneration
Securitization
Pension funds hold AAA rated assets due to
restriction by charter
Hedge fund focus on more risky pieces
Banks hold ”equity tranch” to ensure monitoring
But:
most of risk stayed within banking sector
(although spread across the world)
banks held leveraged AAA assets – tail risk
2009
Diversified portfolios formed on basis of
mortgages, corporate bonds and other
assets
Portfolios are sliced into tranches, sold to
investors with different appetites for risk
Securitization – bad reasons
Supply
Demand
Naiveté – risk underestimated due to past low
correlation among regional housing markets
Search for yield – accept tail risk
2009
Regulatory arbitrage – Basel I required banks
to hold capital of at least 8 percent of loans on
balance sheets, but requirements were lower
for SIVs (structured investment vehicles, i.e.
off balance sheet entities created by banks)
Rating arbitrage – transfer assets to SIVs and
issue AAA rated papers rather than A- rated
papers
Subprime –mortgages in the US
Mortgages to household
with weak financial
background: NINJA – No
Income, No Job or Assets
Often provided by
agents paid on
provision
Simplified credit
evaluation
Often based on
information from
borrower
Teaser rates and
”piggyback” mortgages
to avoid initial down
payment
USA Subprime
Percent of mortgages, stock
2009
Short term funding and
leveraging (low equity shares)
Investors prefer assets with shorth maturity
Most investment projects and mortgages have
long maturities
Leads to ”maturity mismatch” for banks
Increased reliance on extensive short-term
borrowing
Lower equity ratios to increase return on equity
Earn 1 USD on loan of 100 USD
10 % equity => 10 % return on equity;
5 % equity => 20 % return on equity
2009
Provides liquidity
Discipline device for banks
Rating agencies and credit
default swaps CDS
AAA rating important for sale of CDOs
Highly profitable business for rating
agencies
Risk was underestimated
Rating ”at the edge”, i.e. as ”risky as possible”
Insurance: Credit Default Swaps CDS
Extensive reinsurance to other companies
Insufficient capital – monoline insurers had
only 1 percent of amount at risk
Possible to buy CDS without having
underlying asset
2009
Higher fees for structural products
Background – incentives in the
financial sector
Not only new, unknown risk, but also
Incentive based remuneration, bonus for
upside, but no punishment for downside
Measuring return relative to risk lead to
search for other possibilities
Tail risk – win something 9 out of 10, loose a lot
1 out of 10
Herd behaviour – don’t do worse than
others
2009
Low price on risk
”Old, well known” risk, e.g. borrow in foreign
currency
Background – weaknesses in
the regulation
Large parts of financial markets without
capital requirements and supervision
Holes in the regulation
”off-balance-sheet”
Coordination problems and several regulatory
authorities
Insufficient transparency
Procyclical regulation
Good times: asset prices up => equity share
up => lend more => asset prices up
Reverse in bad times
2009
Half of the US credit market, including
investment banks (because no depositors)
House prices in the US,
annual growth rates 1988 - 2008.

Credit default swaps
2009
Amplification mechanisms
Loss on bad loans, and fear of new
losses
Liquidity crisis
Banks more reluctant to lend to other banks
Difficult to obtain short term funding
Banks must sell assets => asset prices fall
Lower asset prices increase loss => sell more
Asset markets become illiquid
Solvency problems
Downgrading of securities and institutions
Procyclical behaviour and regulation
2009
2009
The financial crisis leads to a
recession
Financial crisis leads to lower
investment and lower consumption, so
that GDP falls
Demand falls
Risk increases
More difficult to finance investment projects,
consumption and trade credits
Investments, cars, durables, manufacturing
products severly hit
Recession involves real losses that
amplifies financial crisis
Banks take losses, and must reduce lending
Firms have lower equity and lower sales, more
uncertainty, becomes less credit worthy
2009
Historical experiences of
financial crises after 1945
Reinhart og Rogoff, NBER
Average change from top to bottom
Longlasting reduction in asset prices
Fall in output and employment
Unemployment increases by 7 percent over four
years
GDP falls by 9 percent over two years
Public debt increases
Average increase is 86 percent (not a good
measure, as it depends on initial debt)
2009
House prices fall by 35 percent over six years
Stock prices fall by 55 percent over 3 ½ years
Some lessons for the regulation
of financial markets
More emphasis on stability and less on
competition
Market discipline must improve
Raw leverage caps, not only risk adjusted
Credit rating agencies
Insentives in financial institutions
Liquidity regulation and better liquidity
provision
2009
Supervision and regulation of all activity
which involves system risk
Better information and transparency
Make regulation less procyclical
Lessons – economic policy
Fiscal policy tighter in good times
Global imbalances reduced
International cooperation improved
2009
Monetary policy must reflect concern for
financial stability
