Quoting the Crisis

Shadow banking is a less noticed but more important factor in creating bubbles. Most analysts compare it to the hedge fund industry, which provided leverage for financial speculators with little capital. The shadow banking system is much more because industrial firms engaging in financial activities are more important. Entities such as GE Capital and GMAC provided massive leverage to asset markets with little capital. A shadow banking system is essential to a big bubble.

China’s corporate sector increasingly looks like a shadow banking system. It raises funds from banks, through commercial bills or the corporate bond market, and then channels the funds into the land market. The resulting land inflation underwrites corporate profitability and improves their creditworthiness in the short term.
