<p>"The seeds of today’s disaster were sown in the 1980s, when financial services began a pattern of growth that may only now have come to an end. In a recent study Martin Barnes of BCA Research, a Canadian economic-research firm, traces the rise of the American financial-services industry’s share of total corporate profits, from 10% in the early 1980s to 40% at its peak last year (see chart 1). Its share of stockmarket value grew from 6% to 19%. These proportions look all the more strikingeven unsustainablewhen you note that financial services account for only 15% of corporate America’s gross value added and a mere 5% of private-sector jobs.</p>
<p>At first this growth was built on the solid foundations of rising asset prices. The 18 years to 2000 witnessed an unparalleled bull market for shares and bonds. As the world’s central banks tamed inflation, interest rates fell and asset prices rose (see chart 2). Corporate restructuring, wage competition and a revolution in information technology boosted profits. A typical portfolio of shares, bonds and cash gave real annual yields of over 14%, calculates Mr Barnes, almost four times the norm of earlier decades. Financial-service firms made hay. The number of equity mutual funds in America rose more than fourfold.</p>
<p>But something changed in 2001, when the dotcom bubble burst. America’s GDP growth since then has been weaker than in any cycle since the 1950s, barring the double-dip recovery in 1980-81. Stephen King and Ian Morris of HSBC point out that growth in consumer spending, total investment and exports in this cycle has been correspondingly feeble.</p>
<p>Yet, like Wile E. Coyote running over the edge of a cliff, financial services kept on going. A service industry that, in effect, exists to help people write, trade and manage financial claims on future cashflows raced ahead of the real economy, even as the ground beneath it fell away.</p>
<p>The industry has defied gravity by using debt, securitisation and proprietary trading to boost fee income and profits. Investors hungry for yield have willingly gone along. "</p>
