An unsustainable weakening of credit standards induced a US mortgage lending and housing bubble, whose consumption impact was amplified by innovations altering the collateral role of housing. In countries with more stable credit standards, any overshooting of construction and house prices owed more to traditional housing supply and demand factors. Housing collateral effects on consumption also varied, depending on the liquidity of housing wealth. Lessons for the future include recognizing the importance of financial innovation, regulation, housing policies, and global financial imbalances for fueling credit, construction, house price and consumption cycles that vary across countries.
