How much gas has the USD left in the tank? The following chart may provide a clue. The USD Index has a tendency to peak every 15-16 years. It happened in 1985 at the Plaza Accord and again in 2001 at the top of the tech/telecom stock market bubble. This coincided with the start of the gold bull market. Roll forward another 15 years and you get to 2016. This is what makes the recent USD surge all the more interesting. We could be fast approaching a major peak in the USD that also coincides with the 6-year cyclical bull run in stocks (and maybe bonds too) and bottom in commodities and precious metals. The next major top in the USD and bonds and bottom in gold could be very significant turning points.
