In inflation-adjusted terms and relative to the monetary commodity (gold), commodities tend to become cheaper over the long haul. Another way of saying this is that over the very long-term, gold tends to increase in value relative to commodities in general. This is due to technological progress that enables the production of more for less, as evidenced by the fact that the percentage of the US workforce involved in farming has decreased from over 50% in the 1860s to less than 2% today in parallel with a large increase in per-capita agricultural production. Historically, however, oil has held its ground relative to gold. Why is that and will it continue?
When we say that oil has held its ground, we don’t mean that the gold/oil ratio has been stable. On the contrary, over the 150+ year period covered by the following monthly chart there clearly have been huge swings in the price of oil relative to the price of gold. What we mean is that after a huge move in one direction or the other, in the past the ratio eventually retraced the move.
Of particular interest, the chart shows that since the 1890s there have been four rises in the gold/oil ratio to 80 or above, with the latest one occurring recently, and that each of these previous dramatic upward moves was followed by a decline to below 40 within the ensuing few years. Will it be the same story this time around, that is, should we expect the gold/oil ratio to be back below 40 within a few years?

Before attempting to answer the above question we’ll posit that the oil price has held its ground relative to the gold price over the very long term because artificial barriers have been created to limit oil production and thus cause the long-term average oil price to be higher, in real terms, than would be the case if market forces were allowed to operate unhindered. The most important of these artificial barriers is OPEC, which was created in 1960.
Furthermore, we have just witnessed the creation of another artificial barrier in the form of deliberate destruction of oil production facilities in the Middle East. Even if the US-Israel-Iran conflict has peaked and the current fragile truce evolves into a lasting peace arrangement, due to what already has happened the global production of oil will be lower, and the average price of oil will be higher, during 2026-2027 than it otherwise would have been.
So, as to whether the gold/oil ratio returns to below 40 within the next few years, a lot of will depend on what artificial barriers are placed in the way of oil production growth. This is not knowable, as the determining factor will be political decisions that often are not rational if the goal is to maximise living standards.
That being said, the next monthly chart indicates that a major change in the performance of oil relative to gold may have occurred in 2008.
For decades prior to 2008 the gold/oil ratio oscillated within a wide horizontal range, but in 2008 it commenced an upward trend that has resulted in a move to well above the top of this multi-decade range. This upward trend was ‘kicked off’ by the Global Financial Crisis, but it’s likely that it was sustained in part by the shale revolution that began to have a significant effect on oil production in the early-2010s. Due to the shale revolution, US oil production increased from a low of around 5M barrels/day in 2008 to its current level of around 13.6M barrels/day. This large rise in US production put downward pressure on the oil price and reduced the influence on the oil market of the artificial barrier known as OPEC.

Further to the above, it’s possible that oil is now about 18 years into an ultra-long-term (multi-decadal or even multi-generational) downward trend relative to gold, but a lot will depend on the actions taken by governments to limit the supply of oil.
