Bond yields are rising again. This week we saw the 30 year U.S. Treasury bond close at 3.17%, which does not seem like a particularly important or even dangerous number. In the grand scheme of things it isn't. But it is a very bearish number on a weekly basis looking at a chart of the yield when we look at it within the context of the monthly chart. Rising bonds yields could be the work of the Fed or it could be strategic selling now that the U.S. economy looks like it is in worse shape than what was expected earlier in the year.

While speculation that the Fed may take one of its feet off the accelerator in the next month helped lift the dollar, other countries are easing policy. There has been even more talk about the ECB adopting a negative deposit rate. Continued sub-50 readings in the

It has been a great week for the USD as it gained against all the majors. The New Zealand dollar was the last market where the futures traders were long. Early in the week, the kiwi bought .8316 cents per USD, but by the end of the week, it was down under the 81 handle. Should the weekly chart close around this level, it looks like there will be some more to the downside. Remember one of the tricks of The Turtles, as taught by Ritch Dennis, was to hammer a weak Friday close, or, if the market is soaring, buy some more. Their theory was markets will continue their momentum. Speculators, according to last week's COT report, were big longs in this very small market. This could get ugly.
