Looking beyond the post-2008 fixes

Finance needs to re-establish its role in serving the needs of an inclusive, sustainable economy. Policy and regulatory interventions following the financial crisis can help, by improving oversight and reducing dangerous levels of systemic risks.

Yet the opposite may also be true. Financial institutions increasingly say that post-2008 measures may create new sources of risk and harm the real economy through prudential measures that weaken lending and long-term investing. Many dismiss these complaints, seeing them as self-serving, but there is merit to these concerns.

Some forceful interventions have unintended negative consequences and other, much-needed interventions have simply not happened.

Five warning signals point to continued and emerging problems in the wake of the financial crisis:

?First, is the inefficiency of ultra-abundant liquidity across many financial markets, driven by monetary policy, encouraged by regulations aiming to curb risk-taking on illiquid assets, as well as the rise of technology-powered trading. Paradoxically, such liquidity does not feed into potentially profitable, long-term investment, despite historically low interest rates.

?Second, there is continued fragility of the financial system, in part through the unintended effects of policy and regulatory measures, such as those leading to pro-cyclicality and the favorable tax treatment of debt over equity.

?Third, are growing challenges in sustaining effective oversight, driven in part by the sheer volume and complexity of financial regulation.

?Fourth, developing economies are discovering the downside of the new normal for finance. Global capital flows have become more scarce and costly, partly because of new regulatory restrictions, leaving developing countries caught in an economic pincer in the face of sluggish global demand.

?Fifth, and most serious, is the disconnect between the post-2008 agenda and the urgent need to finance sustainable development. Preferences for short-term, liquid and mostly homogenous assets (in particular sovereign debt) mean that the financial system continues to externalize societal issues such as environmental deterioration and the destabilizing effects of growing inequality.

High levels of public debt and the lack of fiscal space mean that public investment will not deliver the $90 trillion in infrastructure needed globally by 2030.

Environmental limits complicate the equation, as this massive investment needs to be low-carbon, climate-resilient and natural-resource efficient. Some existing physical assets, such as coal reserves, need to be re-valued as they cannot all be used if average global temperature rises are to be kept below the internationally agreed ceiling of 2 degrees Centigrade.

Coal needs to be substituted rapidly out of the energy mix, to combat the longer-term effects of climate change and reduce the public health and broader economic costs of air pollution. The latter makes up almost half of the IMF's most recent estimates of annual global energy subsidies of $5.3 trillion.

Such potentially destabilizing externalities have remained largely out of the scope of post-2008 policy and regulatory frameworks. Standards that incentivize high liquidity and a short-term focus ignore the potential, longer-term, destabilizing effects on the real economy and ultimately back on the financial system.

Macroprudential tools do not address this challenge, still being confined to medium-term horizons, typically the length of a credit cycle. Adjustments in prudential instruments are needed to grapple with secular sources of instability over extended time periods.

This should be a priority for the Financial Stability Board under its G20 mandate to review how central banks should assess and manage climate-related risks. Environmental stress-testing of the balance sheets of major financial institutions is a developing practice, with several countries exploring how to extend this to customary norms.
