It has been a while since US investors have woken up to find that issues in Europe are having a negative effect on our markets.  The charts below highlight the most up to date spreads of Euro sovereign debt yields relative to Germany.  Over the last few days, spreads on Portuguese debt have blown out to record levels, as the Euro debt contagion continues to spread.  While the situation in Portugal will impact our markets, it is interesting to note that for now at least, it is somewhat contained.  As shown in the charts, spreads on debt in other high profile European countries have not seen the type of blowout that we have seen in Portugal.
