Investment for Sustainable Growth

When the 2008 financial crisis hit, outlays on both consumption and housing plummeted, yet the investment that should have picked up the slack never materialized. It is time to usher in an era of high investment in sustainable development.

NEW YORK – The big disappointment in the world economy today is the low rate of investment. In the years leading up to the 2008 financial crisis, growth in high-income countries was propelled by spending on housing and private consumption. When the crisis hit, both kinds of spending plummeted, and the investments that should have picked up the slack never materialized. This must change.

After the crisis, the world’s major central banks attempted to revive spending and employment by slashing interest rates. The strategy worked, to some extent. By flooding capital markets with liquidity and holding down market interest rates, policymakers encouraged investors to bid up stock and bond prices. This created financial wealth through capital gains, while spurring consumption and – through initial public offerings – some investment.

Yet this policy has reached its limits – and imposed undeniable costs. With interest rates at or even below zero, investors borrow for highly speculative purposes. As a result, the overall quality of investments has dropped, while leverage has risen. When central banks finally tighten credit, there is a real risk of significant asset-price declines.

    US President Donald Trump's impulsive decision to pull American troops out of northern Syria and allow Turkey to launch a military campaign against the Kurds there has proved utterly disastrous. But a crisis was already inevitable, given the realities on the ground and the absence of a coherent US or Western policy in Syria.
