For instance, the sixth trend Goldman is forseeing for 2016 is really important:
6. The global savings glut is reversing
The "global savings glut," a term coined by former fed chair Ben Bernanke, was created as oil prices rallied in the late 2000s.
The strategists wrote: "The surges in petrodollar savings in the pre- and post-crisis periods are clearly visible. Equally visible, if less remarked upon, is the recent collapse of petrodollar savings following the collapse of global energy prices. In addition, Exhibit 7 shows the EM FX reserves, too, appear to have peaked (another source of saving cited by Bernanke). In our view, these savings declines are bearish for rates, just as they were arguably bullish for rates during the pre-crisis period."
