The NY Times has an interesting graphic, "A Spectator's Guide to the Euro Crisis" which includes information about the financial linkages between nations in Europe (as well as US bank exposure to the eurozone). It also explores possible scenarios for how the crisis may evolve (best case, worst case, and likely scenarios). Simon Johnson (former IMF economist, currently at MIT) provides comments about the graphic as well as an analysis of the European financial crisis (a policy brief from July 2011).
The guide does a nice job illustrating the interconnections of the global financial system and how problems in one country can reverberate around the world.
