Silver Series Part 3: The World’s Growing Demand For Silver
Silver is the most versatile metal in the world. Not only does it have the highest thermal and electrical conductivity of all metals, but it also has many other impressive properties: silver is antibacterial, durable, reflective, and malleable.
With such a multitude of significant material qualities, it is no surprise that now more than half of silver used today is in industrial processes. Last year, it is estimated that 53% of silver was used in industry – an increase from a total of 46% a decade ago.
Perhaps the most notable industrial sector for silver demand is photovoltaics, where 2.8 million oz of silver is used for every gigawatt of solar energy capacity. The total installed capacity of solar globally is at around 178 GW in 2014, and growth in global installs is also significant, gaining 14% between 2013 and 2014.
The metal’s other main industrial uses include brazing and soldering as well as fabrication. In the former category, using silver for brazing and soldering helps produce leak-tight and corrosion-resistant joints when combining metal parts.
In terms of fabrication, silver-containing vehicles, batteries, and chemical processes are the most important categories for future growth. For use in automotive manufacturing, which has the highest project growth (4.9% CAGR) of categories other than solar, silver is used to coat electrical contacts to ensure the most efficient energy flow. Silver batteries, which have similar energy densities to lithium-ion batteries, are used in military and aerospace applications because they are more reliable and safe. Lastly, silver catalysts are also used to help combine ethylene and oxygen together to create ethylene oxide, which is used in medicine, anti-freeze, and cosmetics.
While industrial uses are the most prominent for the metal, it is investment that has been the real growth engine for silver demand over the last decade.
In 2014, 20% of all silver is used for investment purposes, compared to only 7% a decade ago. The demand for silver coins and bars has more than quadrupled since the early 2000s, and the coin sales of Canadian Maple Leafs and American Eagles have been soaring for years.
It is also interesting to note, especially at a time of such market vulnerability, that the ratio of silver to gold ounces bought in the market increases. This ratio peaked recently during the Global Financial Crisis in 2008, and in the last 12 months it has jumped up to comparable levels.
Jewelry is also a crucial market for silver, and the category is considered by some to serve as an investment and store of wealth as well. Lower prices for silver in recent years have helped jewelry rebound in Asia and the United States in particular.
Globally, silver jewelry fabrication experienced its second year of consecutive growth, increasing 1.5% to achieve a new record high. This was a reflection chiefly of the strong performance of silver jewelry demand from India, which surged 47% from 2013 levels.
A record of 7,063 tonnes of silver were imported to India in 2014, up 15% from 2013. The country imported more silver in November 2014 than they did in all of 2009. This is partially due to India’s rising population and per capital income, and also due to import restrictions on gold in the world’s second most populous country.
Silver demand is multi-faceted, with just over half of demand coming from industry and the rest split between mainly investment and jewelry demand. We will cover the historical returns of investing in silver in-depth with our final part of the Silver Series in the coming weeks.

Silver Through the Ages: The Uses of Silver Over Time
The uses of silver span various industries, from renewable energy to jewelry. See how the uses of silver have evolved in this infographic.
Silver is one of the most versatile metals on Earth, with a unique combination of uses both as a precious and industrial metal.
Today, silver’s uses span many modern technologies, including solar panels, electric vehicles, and 5G devices. However, the uses of silver in currency, medicine, art, and jewelry have helped advance civilization, trade, and technology for thousands of years.
The Uses of Silver Over Time
The below infographic from Blackrock Silver takes us on a journey of silver’s uses through time, from the past to the future.
3,000 BC – The Middle Ages
The earliest accounts of silver can be traced to 3,000 BC in modern-day Turkey, where its mining spurred trade in the ancient Aegean and Mediterranean seas. Traders and merchants would use hacksilver—rough-cut pieces of silver—as a medium of exchange for goods and services.
Around 1,200 BC, the Ancient Greeks began refining and minting silver coins from the rich deposits found in the mines of Laurion just outside Athens. By 100 BC, modern-day Spain became the center of silver mining for the Roman Empire while silver bullion traveled along the Asian spice trade routes. By the late 1400s, Spain brought its affinity for silver to the New World where it uncovered the largest deposits of silver in history in the dusty hills of Bolivia.
Besides the uses of silver in commerce, people also recognized silver’s ability to fight bacteria. For instance, wine and food containers were often made out of silver to prevent spoilage. In addition, during breakouts of the Bubonic plague in medieval and renaissance Europe, people ate and drank with silver utensils to protect themselves from disease.
The 1800s – 2000s
New medicinal uses of silver came to light in the 19th and 20th centuries. Surgeons stitched post-operative wounds with silver sutures to reduce inflammation. In the early 1900s, doctors prescribed silver nitrate eyedrops to prevent conjunctivitis in newborn babies. Furthermore, in the 1960s, NASA developed a water purifier that dispensed silver ions to kill bacteria and purify water on its spacecraft.
The Industrial Revolution drove the onset of silver’s industrial applications. Thanks to its high light sensitivity and reflectivity, it became a key ingredient in photographic films, windows, and mirrors. Even today, skyscraper windows are often coated with silver to reflect sunlight and keep interior spaces cool.
The 2000s – Present
The uses of silver have come a long way since hacksilver and utensils, evolving with time and technology.
Silver is the most electrically conductive metal, making it a natural choice for electronic devices. Almost every electronic device with a switch or button contains silver, from smartphones to electric vehicles. Solar panels also utilize silver as a conductive layer in photovoltaic cells to transport and store electricity efficiently.
In addition, it has several medicinal applications that range from treating burn wounds and ulcers to eliminating bacteria in air conditioning systems and clothes.
Silver for the Future
Silver has always been useful to industries and technologies due to its unique properties, from its antibacterial nature to high electrical conductivity. Today, silver is critical for the next generation of renewable energy technologies.
For every age, silver proves its value.
Visualizing 50 Years of Global Steel Production
Global steel production has tripled over the past 50 years, with China’s steel production eclipsing the rest of the world.
Visualizing 50 Years of Global Steel Production
From the bronze age to the iron age, metals have defined eras of human history. If our current era had to be defined similarly, it would undoubtedly be known as the steel age.
Steel is the foundation of our buildings, vehicles, and industries, with its rates of production and consumption often seen as markers for a nation’s development. Today, it is the world’s most commonly used metal and most recycled material, with 1,864 million metric tons of crude steel produced in 2020.
This infographic uses data from the World Steel Association to visualize 50 years of crude steel production, showcasing our world’s unrelenting creation of this essential material.
The State of Steel Production
Global steel production has more than tripled over the past 50 years, despite nations like the U.S. and Russia scaling down their domestic production and relying more on imports. Meanwhile, China and India have consistently grown their production to become the top two steel producing nations.
Below are the world’s current top crude steel producing nations by 2020 production.
|Rank||Country||Steel Production (2020, Mt)|
|#5||🇺🇸 United States||72.7|
|#6||🇰🇷 South Korea||67.1|

Despite its current dominance, China could be preparing to scale back domestic steel production to curb overproduction risks and ensure it can reach carbon neutrality by 2060.
As iron ore and steel prices have skyrocketed in the last year, U.S. demand could soon lessen depending on the Biden administration’s actions. A potential infrastructure bill would bring investment into America’s steel mills to build supply for the future, and any walkbalk on the Trump administration’s 2018 tariffs on imported steel could further soften supply constraints.
Steel’s Secret: Infinite Recyclability
Made up primarily of iron ore, steel is an alloy which also contains less than 2% carbon and 1% manganese and other trace elements. While the defining difference might seem small, steel can be 1,000x stronger than iron.
However, steel’s true strength lies in its infinite recyclability with no loss of quality. No matter the grade or application, steel can always be recycled, with new steel products containing 30% recycled steel on average.
The alloy’s magnetic properties make it easy to recover from waste streams, and nearly 100% of the steel industry’s co-products can be used in other manufacturing or electricity generation.
It’s fitting then that steel makes up essential parts of various sustainable energy technologies:
- The average wind turbine is made of 80% steel on average (140 metric tons).
- Steel is used in the base, pumps, tanks, and heat exchangers of solar power installations.
- Electrical steel is at the heart of the generators and motors of electric and hybrid vehicles.
The Steel Industry’s Future Sustainability
Considering the crucial role steel plays in just about every industry, it’s no wonder that prices are surging to record highs. However, steel producers are thinking about long-term sustainability, and are working to make fossil-fuel-free steel a reality by completely removing coal from the metallurgical process.
While the industry has already cut down the average energy intensity per metric ton produced from 50 gigajoules to 20 gigajoules since the 1960s, steel-producing giants like ArcelorMittal are going further and laying out their plans for carbon-neutral steel production by 2050.
Steel consumption and demand is only set to continue rising as the world’s economy gradually reopens, especially as Rio Tinto’s new development of atomized steel powder could bring about the next evolution in 3D printing.
As the industry continues to innovate in both sustainability and usability, steel will continue to be a vital material across industries that we can infinitely recycle and rely on.
