Today's NYSE outage is all anyone can talk about at the moment, but markets haven't really paid it much attention. Keep in mind that a majority of trading happens elsewhere. If the CME and NYSE were down simultaneously, it would be a much bigger deal, but even then, cash trading in Treasuries and MBS would continue.
To put the impact in perspective, let's consider S&P futures, the traders' choice when it comes to "the stock market." Prices were as low as 2043 overnight, and had been at domestic-session lows of 2047 before the NYSE outage. After the outage, prices briefly returned to 2043 and are now back up to 2047. Pretty ho-hum, especially in light of yesterday's 2035 lows.
Bond markets have been even less interesting, holding a narrow range today that rests well inside yesterday's highs and lows. On a positive note, that narrow range is at least in slightly stronger territory than yesterday's closing levels--thus making for green on the screen and rate sheet improvements.
