Call it Lehman 2.0, sovereign risk flare up, or plain old money run, the liquidity crunch from last week almost killed the US equity market, has generated an unprecedented swing in FX pairs, and is starting to move into key credit indicators and spreads. The "big bail out" from the weekend has come and gone (unless Trichet is preparing to release something at 5:59pm Eastern tomorrow), and if Goldman is correct will have no material impact on markets... Which means that the downward path of least resistance will continue. And with equity markets not only decoupling from the rest of the world, but from the credit market as well, as they migrate to a plane of existence of their own, replete with unicorns, rainbows and spittoons full of hopium, keeping an eye out on early stress indicators from the credit markets is critical - credit is and has always been a far better early warning of market health, or lack thereof, than the HFT controlled, rebate-driven trading action in the shares of C, FNM, FRE, AIG, and other bankrupt pennystocks which account for up to 40% of daily trading volume. Earlier today, we touched upon some of the key early warning indicators to watch for in determining if the European contagion is going airborne. Below, we share a presentation from Morgan Stanley's Jim Caron, Measuring Risk: Extracting Market Sentiment from the Interest Rate Markets, in which the credit strategist provides a much more detailed framework of what critical credit signals are and how to interpret them. We recommend that all those still trading, either with their own, or other people's money, familiarize themselves with this 27-page overview.
