How much silver is in the world?
The rarity of both precious metals becomes apparent when we consider how little gold and silver have been mined throughout history – just 190,000 tonnes of gold and 1.6 million tonnes of silver. Or in ounce terms, 6.1 billion oz of gold and 51.3 billion oz of silver. All the gold ever mined in the world could fit into a cube 21.6 meters on each side, and all the above-ground silver could fit into a 52m cube.
According to the Silver Institute’s annual silver survey, in 2018, the latest data available, there were 2.457 billion ounces of silver being held in vaults, silver ETFs or ETPs [exchange traded funds/products] , government silver holdings and industrial silver stockpiles.
There are just slightly more than 6.1 billion troy ounces of gold above ground. Approximately 50% of gold is jewelry, and 40% is .999 fine bullion – or 2.5 billion ounces of gold currently available for investment purposes.
The all-time estimated mined Gold-Silver ratio is about 8.8.1 – for every 8.8 ounces of silver mined we have mined 1 ounce of gold. We would expect there to be roughly eight times more silver than gold. But there isn’t, instead above ground stocks of investment grade gold and silver bullion are virtually even.
Industrial demand for silver is the reason for the flip-flop. The white metal is used in a mind-boggling 10,000 industrial applications.
While most of the mined gold is still around, either cast as jewelry, or smelted into bullion and stored for investment purposes, the same cannot be said for silver. It’s estimated around 60% of silver is utilized in industrial applications, leaving only 40% for investing. And of the 60% demanded by industry, 8 of 10 ounces is either used up in manufactured products or discarded in landfills. Some silver researchers say closer to 90% has been lost to landfills. Perhaps we should be mining them?
In sum, both silver and gold have roughly the same amount above-ground supply available for investment purposes. However, since very little gold is used by industry, it trades as an investment commodity – moving up and down in relation to factors like the US dollar, inflation, interest rates and sovereign bond yields.
In comparison, silver has a relatively small amount for investment, just 40% of total supply. Because over half of global supply is needed for industrial applications, silver trades much more like an industrial metal than an investment commodity. As we shall see in the section below, when gold is over-valued compared to silver, investors take advantage of the arbitrage opportunity, by selling some of their gold holdings to buy silver.
This also explains silver’s volatility. Because the investment market for silver is so small (60% is locked up in industrial uses) it swings up and down wildly with relatively low volumes.
Companies that are buying silver as a manufacturing input can’t risk buying it on the spot market; this would be too unpredictable.
Record demand
A record amount of silver was sought in 2018. According to the Silver Institute’s annual survey, total physical demand last year rose 4% to 1,033.5 million ounces – a three-year high. The need for silver was driven mostly by purchases of bars and coins, jewelry and silverware.
Unlike gold which serves primarily an investment function and as material for jewelry (known as “the fear trade and the love trade”), silver’s properties make it ideal for a number of applications – almost as many as oil. The metal is strong, malleable and conducts heat and electricity better than any other material. Gold also has these properties but it is too expensive to use in circuit boards, solar panels, electric cars, etc.
Over 50% of silver demand comes from industrial uses like solar panels, electronics, the automotive industry and photographic applications.
Despite the increased imperative for installing solar power as a means of moving away from carbon-intensive coal and natural gas, silver’s use in the photovoltaic sector actually dropped 1% last year. According to the 2019 World Silver Survey, that was due to “reduced silver loadings in solar modules”, but the drop was compensated for by solid demand from electronics, brazing alloys and solders.
And while companies have managed to reduce the amount of silver in solar panels, a practice known as “thrifting,” photovoltaics will remain a critical sector for silver, says Johann Wiebe, lead analyst at the GFMS Team/Refinitiv, the research firm behind the survey.
“Solar power capacity is expected to continue to grow and that is going to have a stronger impact on demand than the effects of thrifting,” he told Kitco News.
The solar power industry currently accounts for 13% of silver’s industrial demand.
Falling mine supply
The amount of silver produced from mines fell by 21.2 million ounces last year, the third consecutive drop after 13 years of uninterrupted supply growth. The 2019 World Silver Survey attributes the 855.7Moz loss to falling production at lead and zinc mines; 75% of silver is mined as a by-product, mostly of gold, copper, lead and zinc.
Two examples are the suspension of the mining license at Tahoe Resources’ Escobar mine in Guatemala – the world’s third largest silver mine – and reduced output due to a fire at Teck Resources’ Trail smelter in British Columbia. Unexpected maintenance issues and lower grades at the Fire Creek and Kid Creek mines drove US silver production down by 5.7Moz, 17% less than 2017.
As for 2019, mine supply from the top three silver-producing countries, Peru, Chile and Mexico, all dropped in the first half of this year. Data collected from each country showed Peru’s H1 silver production was down 10%, Chile fell 7% and Mexico saw a 4% decrease from January to May.
Analytics company GlobalData crunched the silver numbers and came out with a positive outlook for silver producers, right up until 2023. The firm says that year, global silver production should top a billion ounces (compared to 920Moz in 2018), with 50 new projects in the pipeline expected to produce silver either as a primary or secondary metal. The largest mines to come online in the next three years include the El Cajon mine in Mexico, Lundin Gold’s Fruta del Norte and the Mirabel mine in Ecuador, plus the Oernoe and Udokan mines in Russia.
Silver output in 2019 is expected to decline to 913.5Moz.
The gold-silver ratio
We can use the gold-silver ratio to find out how silver prices compare to gold, since the two precious metals have roughly the same amount of above-ground supply – 6.1 billion ounces, and around the same level of 0.999 fine bullion used for investments – 2.5Boz.
The gold-silver ratio is simply the amount of silver one can buy with an ounce of gold. Simply divide the current gold price by the price of silver, to find the ratio.
On June 12, the gold-silver ratio hit a 26-year high by breaking through the 90-ounce mark – meaning it took over 90 ounces of silver to purchase one ounce of gold. The higher the number, the more undervalued is silver or, to put it another way, the farther gold is pulling away from silver, valued in dollars per ounce.
Over time, this is exactly what has happened.
A reading of history tells us that in ancient Egypt, the two metals were practically equals, with only 2.5 parts silver equivalent to 1 part gold. Meaning that in 3,200 BC, you could trade 5 ounces of silver for 2 oz of gold. Imagine that! If somebody took that trade today, 5 oz of silver valued at $15 per ounce would cost the buyer $75, and the seller would be parting with 2 oz of gold worth $2,800.
When the Spanish conquistadors raided the Aztec empire the gold-silver ratio established in the Edict of Medina was 10.07 parts silver for 1 part gold. In the Middle Ages it was 12:1, and under France’s monetary standard in the 19th century, the ratio was set at 15.5:1. After silver was demonetized, in favor of the gold standard, silver took quite a hit; the ratio spiked to 30 at the beginning of the 20th century and has averaged 58.5 since the dollar peg was removed from the gold price by President Nixon in 1971, reports Bullion Vault.
So what does the gold-silver ratio mean and how can we use it? In the simplest terms, the gold-silver ratio tells us, as precious metals investors, which is under-valued, silver or gold? Which is over-valued, silver or gold?
The way to make money is to trade “on the extremes” of the ratio. For example at the current ratio of 84:1, a trader who has an ounce of gold could sell his gold for 84 ounces of silver.
The Balance explains this rather well, and gives a couple of historical examples.
Watching the silver to gold ratio can provide extremely useful insights into both precious metals.
Historically, it would have taken approximately 30 to 40 ounces of silver to buy one single ounce of gold.
This typically means that a ratio above 60 represents undervalued silver, while a ratio below 20 demonstrates undervalued gold.
In 1915, you could have traded 38 ounces of silver in exchange for one single ounce of gold. In 1940, near the beginning of World War II, gold soared as a safe haven asset, and the ratio was 97 to 1.
With inflation running wild in 1979, the Federal Reserve Chairman, Paul Volcker, raised interest rates to 21 percent. This resulted in driving down prices of gold, which eventually created the lowest-ever silver to gold ratio of 14.
While trying to predict future moves in the prices of the individual metals can be difficult, it may be much easier to invest based on the relationship between the two. When the silver to gold ratio is low (less than 30), then silver itself will typically rise faster than (or fall slower than) any moves you see in gold.
Gold and silver prices can move dramatically when the gold-silver ratio compresses.
Silver companies?
Recall that only 25% of silver production originates from primary silver mines. The rest is mined as a by-product of gold, copper, zinc and lead deposits. Silver exploration companies with pure-play silver projects are therefore rare, and typically trade at a premium to gold equities.
Companies with polymetallic mines that produce silver as a by-product are also highly desirable as an investment, especially during the current period of falling silver mine production.
Adam Hamilton over at Zeal Intelligence does a great job of analyzing the silver sector’s performance in the second quarter, which coincides with gold’s recent run. Hamilton notes that Q2 numbers are a bit skewed because it took a while for traders to be convinced that gold’s up-leg was real. But he is optimistic about the third quarter especially considering how undervalued silver is right now. Here’s Hamilton:
The bottom line is the major silver miners had a challenging Q2. Silver languished the entire quarter, on its way to horrific quarter-century-plus lows relative to gold. Silver didn’t start perking up until mid-July, after gold’s decisive bull-market breakout had lasted long enough to convince traders gold’s upside was real and sustainable. So silver miners’ operating cash flows and earnings were way down last quarter.
That will really change in Q3 as long as silver doesn’t plummet into quarter-end. It’s incredible how fast silver miners’ fundamentals improve with higher silver prices. And silver’s upside potential is enormous, as it has a vast way to go to normalize relative to prevailing gold prices. The more that precious-metals sentiment improves, the more capital will flow into the tiny silver sector catapulting miners’ stocks far higher.
Conclusion
This article has hopefully shown how silver, despite being 17.5 times more abundant than gold in the earth’s crust, is just as rare, maybe even rarer than gold, when it comes to the availability of investment-grade, 0.999 fine bullion. There just isn’t a lot of it out there, given that 60% of silver is used by industry.
Both metals each have about 2.5 billion ounces currently available. The difference between them is that 60% of silver’s supply is going to be used by industry – not bought by investors – and either lost to manufacturing or landfilled.
Demand for silver has never been better and mined supply is shrinking, which should put a floor under silver prices, which have seen a bottom-to-top gain (spot silver) of 28% over the past six months.
At Ahead of the Herd, we believe that the best way to benefit from silver prices going up is to invest in quality juniors that are either exploring for silver or have projects with silver as a by-product. History has shown that investing in silver juniors is the best leverage against a rising silver price.
