Savings Equals Investment: How Shadow Banking Broke the Economic Identity
Book: Financial Stability: Fraud, Confidence and the Wealth of Nations by Frederick L. Feldkamp and R. Christopher Whalen
ISBN: 978-1-118-93579-8
Chapter 16 is the shortest proof chapter in Part Three, but it might be the most devastating. Feldkamp and Whalen take a basic axiom of economics and show how violating it blew up the world economy.
Savings must equal investment. The total capital goods of a nation must equal the sum of all public and private debt plus equity.
That is not a policy preference. It is arithmetic.
The 2005 Balance Sheet
In 2005, U.S. capital goods totaled roughly $100 trillion. Reported debt was about $50 trillion. Equity was the remaining $50 trillion. Worldwide, each category was roughly double.
Then there was shadow banking. Off-balance sheet liabilities were said to total $30 trillion in the United States and $67 trillion globally.
Where did that fit? It did not. It was hidden.
The Moment Everything Changed
The crisis began in 2007 when some financial institutions announced they would not honor off-balance sheet liabilities. Investors who had parked cash in shadow banking funds ran for the exits. Then everyone started questioning equity values using the savings-investment identity.
If reported U.S. debt was understated by $30 trillion, equity was not $50 trillion. It was $20 trillion. Worldwide, equity dropped from $100 trillion to $33 trillion.
Feldkamp and Whalen call this a massive “oops.” It was equivalent to shooting a howitzer across the bow of the investment ship.
The Numbers Line Up
Every investor running a valuation model like Table 9.1 from Chapter 14 would have seen the same result. Add $30 trillion of shadow banking liabilities to reported debt and equity must fall by $30 trillion, roughly 60 percent. When base rates fell to 1 percent and spreads widened to Armageddon levels, the experienced loss correlated directly to that assumption.
Smart money knew equity was headed for a 60 percent drop in the United States and 67 percent worldwide. By March 2009, that is exactly what happened. Irving Fisher’s 1933 predictions about debt-deflation came true again.
Paulson’s Super SIV announcement to rescue Citigroup and other too-big-to-fail banks in 2007 kicked off a 13-month slide to the credit spread spike of September through November 2008.
The Bridge Out
The world fell into debt-contraction deflation. It was saved by replacing unsustainable private-sector debt with public-sector debt at rates low enough to support greater equity values over time. That allows a later return to private sector lending.
Under the theory of financial stability, full recovery is possible if market policies let private participants refund the Fed’s bridge loans with private substitutes that sustain renewed expansion.
Economics supports the theory. But the bridge only works if the hidden debt stays visible going forward.
Why This Chapter Hit Me
I think about accounting identities as classroom exercises. Savings equals investment. Assets equal liabilities plus capital. Current account deficits equal capital inflows minus domestic savings. They feel abstract until they are not.
The 2007 revelation was not that housing prices were high. It was that the world’s balance sheet had a $67 trillion hole in it. Investors did not need to know which bank held which off-balance sheet obligation. The safe move was to sell everything potentially affected.
That is panic, but it is rational panic. When you discover the fundamental equation of economics has been wrong for years, you do not wait for details.
Feldkamp and Whalen are not arguing that shadow banking was a side issue. It was the catalyst. The law chapter explained why the hidden debt existed. This chapter explains what happened when investors finally counted it.
Recovery depends on putting that debt back on balance sheets where it always belonged. The math does not forgive hiding.
