The IMF has reported that the global financial system is on a path to improved financial stability, but faces a host of transitional challenges borne out by regional vulnerabilities and policy regimes. One challenge is managing the United States' disengagement from its accommodative monetary policy. Doing so in an elegant, orderly manner could be difficult as markets adjust to reflect investors' expectations of a new monetary regime with higher interest rates. Interest rates could rise too sharply if exacerbated by a structural decline in market liquidity from higher interest rates and greater volatility, or by structural deleveraging in short-term securities and in the shadow banking system (particularly the mortgage market and real estate investment trusts). Other central banks are contemplating ways to exit unconventional monetary policies employed in recent years. Some nations however, such as Japan, are attempting stimulus programs at larger scales to combat deflationary pressures. The Eurozone's nations implemented myriad national reforms aimed at strengthening the monetary union and alleviating stress on banks and governments. Yet some European nations such as Portugal, Italy, and Spain continue to struggle with heavily leveraged corporate sectors and fragmented financial markets in which investors face pricing inefficiency and difficulty identifying quality assets. Banks operating in such environments may need stronger provisions in place to withstand corresponding market adjustments and absorb potential losses. Emerging market economies face challenges to greater stability as bond markets indicate heightened sensitivity to monetary easing from external investors flooding into domestic markets, rendering exposure to potential capital flights brought on by heavy corporate leveraging in expansionary credit environments. Policymakers in these economies are tasked with transitioning to more sustainable and balanced financial sectors while still fostering market growth so as not to provoke investor withdrawal.
