Hernando de Soto, Peruvian Economist shares his thoughts via the Wall Street Journal

The Obama administration has finally come up with a plan to deal with the real cause of the credit crunch: the infamous "toxic assets" on bank balance sheets that have scared off investors and borrowers, clogging credit markets around the world. But if Treasury Secretary Timothy Geithner hopes to prevent a repeat of this global economic crisis, his rescue plan must recognize that the real problem is not the bad loans, but the debasement of the paper they are printed on.

Today's global crisis -- a loss on paper of more than $50 trillion in stocks, real estate, commodities and operational earnings within 15 months -- cannot be explained only by the default on a meager 7% of subprime mortgages (worth probably no more than $1 trillion) that triggered it. The real villain is the lack of trust in the paper on which they -- and all other assets -- are printed. If we don't restore trust in paper, the next default -- on credit cards or student loans -- will trigger another collapse in paper and bring the world economy to its knees.

If you think about it, everything of value we own travels on property paper. At the beginning of the decade there was about $100 trillion worth of property paper representing tangible goods such as land, buildings, and patents world-wide, and some $170 trillion representing ownership over such semiliquid assets as mortgages, stocks and bonds. Since then, however, aggressive financiers have manufactured what the Bank for International Settlements estimates to be $1 quadrillion worth of new derivatives (mortgage-backed securities, collateralized debt obligations, and credit default swaps) that have flooded the market.
