The operational frameworks of central banks have changed fundamentally in the wake of the great financial crisis. Non-conventional monetary policies have become the new normal in all large developed economies. Their main forms have been balance sheet expansion and risk premium compression through asset purchases and targeted lending, forward guidance in respect to future monetary policy, and changes to collateral rules. Future non-conventional policies could team up with fiscal expansion to create versions of “helicopter money”. Non-conventional policies have created new systemic risks, arising from [i] prolonged sedation of financial markets through containment of asset price volatility, [ii] exhaustion of scope for further monetary stimulus in future crises and [iii] addiction of economies to cheap funding.

Basic Summaries on Systemic Risk
Systemic Risk I: Non-Conventional Monetary Policy
The Federal Reserve has relied heavily on non-conventional monetary policy since the great financial crisis. Most prominently it has purchased treasuries and mortgage-backed securities in excess of a quarter of concurrent GDP, compressing both term and credit risk premiums by unprecedented margins. Forward guidance for rates and asset purchases has compounded the effect. Deflation risk and expectation management have led to new policy principles, such as excess stimulus. Side effects include the potential addiction of the financial system to highly accommodative conditions. Read more
The European Central Bank runs one of the most complex monetary policy regimes in the world. Since the euro area sovereign crisis its operating framework has extended well beyond regular liquidity supply and now includes [i] long-term full-allotment and targeted lending operations, [ii] large-scale asset purchases, [iii] active and comprehensive collateral policies, [iv] flexible forward guidance on policy operations and [v] a contingent facility to intervene in government bond markets in case of sovereign debt crises.

Systemic Risk II: Government Finances
Public debt ratios in the developed world have reached record highs. This has reduced governments’ capacity to stabilize financial and economic cycles in the future. It has also increased the dependence of sovereign debt sustainability on low real interest rates. Avoidance of excessively tight fiscal conditions and protection of sovereign solvency in developed economies partly relies on “financial repression”: a set of macroeconomic and regulatory policies that channels cheap funding to public budgets for a prolonged period of time.

Systemic Risk III: Financial System
The great financial crisis revealed vulnerabilities of the regulated banking system’s capital structure, liquidity reserves and resolution regimes. This has given rise to an unprecedented expansion and tightening of regulatory rules that include a massive increase in minimum capital ratios, mandatory minimum leverage ratios, new compulsory liquidity ratios and new resolution regimes. The new rules may have unintended consequences, however, including tighter bank lending conditions and more regulatory arbitrage. Read more.
Shadow banking means financial intermediation outside the reach of standard regulation. Shadow banks engage in term, credit and liquidity transformation similar to regulated banks and function principally to channel institutional cash pools to the funding of asset holdings. This makes them an essential part of financial markets. Often this intermediation takes place in a complex multi-institutional setting. The special vulnerability of the shadow banking system arises from its dependence on collateral (asset) value and the absence of a safety net in form of central bank backstops. Read more.
Emerging markets have greatly increased in importance since the 1990s. In particular, local-currency bonds and foreign-currency corporate debt have expanded rapidly. Emerging economies and political systems are now highly dependent on global financial conditions and their feedback onto developed markets is powerful. A particular concern is China, due to its size and aggressive use of financial repression to sustain high levels of leverage and investment. The expected decline in China’s medium-term growth will put the sustainability of private debt, corporate earnings and property prices to a test. Read more.
