Today’s Treasury yield curves (actives and on/off the run) as well as the Dollar Swaps and OIS curves are steeply upward sloping. Again, notice the downward sloping segment of the OIS curve.
But if we look at these curves on January 4, 2014, we see that the curves are even more steeply sloped and all curves are pretty uniform.
One curve, the US Treasury 10Y-2Y, seems hell bent on inverting (e.g. 2Y yield > 10Y yield).
