Housing finance is a hot topic across the developed and developing world, though for different reasons. With some developed economies just coming out of a housing slump and others still in the middle of it (including my current host country, the Netherlands), often caused by easy and excessive access to mortgage credit before the crisis, households in many developing countries suffer rather from a dearth of long-term financing options. To illustrate this discrepancy, total mortgage debt outstanding in the Netherlands is equivalent to 83% of GDP, whereas it amounts to less than one percent of GDP across many low- and lower-middle-income countries in Asia and Africa. What explains these differences? Are underdeveloped housing finance systems just a symptom of the general shallowness of financial systems across developing countries? Or are there country factors and policies that specifically explain underdeveloped mortgage markets?
In a recent paper with Anton Badev, Ligia Vado and Simon Walley, we try to answer some of these questions with new data on mortgage depth and penetration. Specifically, drawing on a painstaking exercise of putting together country-level information on the depth of mortgage finance systems across countries and over time and using the recent data on the use of housing finance in the Global Findex database, we explore factors explaining the large cross-country variation in housing finance across the world
