Before revision:  Focusing on the largest strongly-connected core component of the threshold network, while the edge threshold is set according to the percolation properties of the long-term debt securities network, we identify two early-warning indicators for global financial distress. The spread of certain financial derivative products, such as credit default swaps and equity-linked derivatives, scales with the edge density of the long-term debt securities network .
After revision:  Focusing on the largest strongly-connected core component of the threshold network, while the edge threshold is set according to the percolation properties of the long-term debt securities network, we identify two early-warning indicators for financial crises are identified: First, the algebraic connectivity of the equity securities network, as a measure for structural robustness, drops close to zero already in 2005, while there is an over-representation of high-degree off-shore financial centres among the countries most-related to this observation, suggesting an investigation of such nodes with respect to the structural stability of the global financial system. Second, using a phenomenological model, the edge density of the long-term debt securities network .
