The US Dollar Index is not a measure of the value of the US dollar relative to gold. However, there is a relationship between the US Dollar Index and gold price rallies.
The best gold price rallies came during periods where the US dollar index was in a declining trend.
During the 70s, for example, the US dollar index was in decline during the major gold rallies (1971 to 1974, and 1976 to 1980).
The same, but opposite, is also true for the biggest gold declines, in that they occur when the US dollar index is having its best rallies.
Below, is a US Dollar Index chart (from tradingview.com) since 2012:
For many reasons, the price pattern since June 2014, is not likely a bullish flag or pennant-type pattern. Notice the divergence between price and the RSI (between the two blue lines) – this is one reason. Price has marginally made a higher high, however; the RSI has made a significantly lower high instead. This suggests that the US Dollar Index is going lower.
Therefore, it is likely to follow the RSI to the June 2014 breakout level, and even possibly lower. With this kind of decline in the US Dollar Index, gold is likely to have a strong rally.
Previously, I have shown how the long-term analysis of the US Dollar Index suggests that the gold rally is likely to be similar to the gold rally of the late 70s. Below, is an updated version of that chart:
On the chart, I have marked two fractals (1 to 5). Both fractals exist in similar conditions – relative to the relevant Dow/Gold ratio peaks (1966 and 1999). If the current pattern continues to follow the 70s pattern, then the US Dollar Index is likely to decline significantly over the coming months.
This analysis also indirectly shows that gold is likely to perform in a similar manner to how it moved from about $100 to $850 in the late 70s. Furthermore, the analysis suggests that we are now at a point similar to January/February 1977. If this pattern plays out like it did in the late 70s, and gold has a similar rally, then we will see a gold price in excess of $8000.
Based on my other analysis, including the likelihood that Dow is likely to collapse during the coming US Dollar Index decline, it is very likely that the current gold rally will far exceed the one of the late 70s.
