Amid the current turmoil surrounding tariffs and trade wars, I have been re-reading “Economics: The User’s Guide” by Ha-Joon Chang.
First published in 2014, this highly accessible introduction to economic theory and practice was written in the wake of the GFC, and the fallout that ensued from the US housing bubble and the consequential collapse (and public bailout) of major banks and financial institutions. The US bubble was largely caused by an imbalance in housing supply, poor lending standards, and over-engineering of mortgage-backed securities that quickly unraveled when banks lost confidence in each other, causing a major credit crunch and a lack of market liquidity.
Chang couldn’t have foreseen COVID and the knock-on effect on global supply chains and the impact of lock-down policies on overall productivity. He overlooks (ignores?) Bitcoin, a key ideological and technological response to the GFC, and he downplays the role of innovation in economic growth. However, his historical survey, his analysis of major economic theories (or “schools”) and his explanation of the roles that governments and the private sector play are all spot on and serve as a great resource for anyone wanting to try and make sense of the world.
Given the credit crunch at the heart of the GFC, the recent sell-off in the US bond markets reminds us that:
1. History repeats itself time and time again (albeit for different reasons)
2. Global markets are deeply interconnected, despite various attempts at de-coupling and policies designed to challenge globalisation and bring about increased protectionism
3. The US housing market is heavily reliant upon foreign investors since US treasuries both create market liquidity for new mortgage lending, and set key interest rates for borrowers – and major holders of US treasuries are foreign governments and institutional investors
The US mortgage market is underpinned by a near-socialist funding model (in the form of Fannie Mae and Freddie Mac), a propensity for long-term fixed rate loans, and a significant volume of non-recourse mortgages.
If a global trade war results in higher cost of goods for US consumers, and a bond sell-off results in higher interest rates, could we see a repeat of the GFC but driven by different causes?
