In what S&P calls a 'Perfect Storm', the next four years will see a minimum of $30 trillion in companies' refinancing needs related to maturing bonds and loans and further they expect $13-$16 trillion more debt will be required to finance growth. With bond portfolios over-stuffed with corporate debt (since angst over sovereign risk has skewed asset allocation away from that cohort) the rating agency is concerned that ongoing bank deleveraging, these huge debt re-funding requirements, and the diminishment of central banks and governments to do anything about it leave serious problems with a credit overhang so large. Critically, especially as we hear calls for 'growth' plans from Europe, is the increasing likelihood that, as Reuters reports, this will potentially influence corporate credit quality and "alter the fragile equilibrium that currently exists in the global corporate credit landscape". While S&P expect the refinancing needs may well be met "This global wall of nonfinancial corporate debt will potentially compound the credit rationing that may occur as banks seek to restructure their balance sheets, and bond and equity investors reassess their risk-return thresholds" which "raises the downside risk in global markets" as an inability to finance growth may well be the catalyst for another risk flare. "Governments and central banks have less fiscal and monetary flexibility to prevent serious problems emanating from future market disturbances. A perfect storm scenario would likely cause financing disruptions even for borrowers that are not highly leveraged."
Of course the size of this massive refinancing wall dwarfs the recent discussion of how much of Europe's financial system's equity market cap is nothing but vaporware - since we note that 30% of this $30 trillion is for European financials and corporations.
