The market paricipants are said to be waiting for Janet Yellen to either keep rates where they are or raise them modestly. The market is telling us that rates are going up, hence the price of TBonds down. And with oil signalling it's going higher it would be good to look  at the Crude/Tbond (30 year) ratio which fell 67 percent from its September 2013 high to its low made on August has since reversed a sharp downtrend and is now consolidating the initial flurry and seems to have the potential to rise 41 percent to the previous high. The InvesTRAC short term indicators are rising. In theory it makes sense to buy crude and sell Tbonds in equal value.
