US at capacity
The following graph was recently released by Deutsche Bank. Essentially in the USA, production is back to the level of full capacity of the economy. Full capacity (and thus full employment) is a marker of when inflationary pressure will most probably creep back in (as, for example, workers are able to command wage increases).
This is likely to mark changing economic dynamics, such as increasing US (and global) interest rates and impact on relative currency exchange rates.
