Just been reading up on platinum and honestly, it's one of those metals that doesn't get enough attention from retail investors. Sure, everyone talks about gold and silver, but platinum is actually the third most-traded precious metal globally and the applications are way more interesting than people realize.

Here's what caught my attention - the use of platinum in automotive catalytic converters is massive. We're talking about converting over 90 percent of harmful emissions like hydrocarbons and carbon monoxide into less harmful substances. By 2024, the automotive sector alone was pulling in around 3.17 million ounces, with projections climbing to 3.25 million ounces in 2025. That's serious industrial demand that's not going anywhere, especially as pollution regulations keep tightening. Over 95 percent of new vehicles sold annually have catalytic converters now, so this isn't some niche market.

The jewelry market is another big one. Platinum's been used for ornaments for thousands of years - South Americans were crafting with it over 2,000 years ago, and Egyptians picked it up around the 7th century. Today, China dominates the platinum jewelry market, and the use of platinum in this sector was expected to hit 1.95 million ounces in 2024, growing to 1.98 million ounces in 2025. The metal just works for jewelry because it doesn't tarnish, stays strong through repeated heating, and doesn't oxidize.

What's really fascinating though is the industrial and medical side. Platinum goes into everything - hard drives, electronics, sensors, dental work, even cancer-fighting drugs like cisplatin and carboplatin for testicular, ovarian, breast and lung cancers. The use of platinum in medical devices and implants keeps growing because of its durability, conductivity and biocompatibility. Medical demand was forecast at 303,000 ounces in 2024, climbing to 314,000 ounces in 2025. Industrial applications combined with medical were expected to total 2.43 million ounces in 2024.

Now, the interesting part - platinum is 30 times rarer than gold and much harder to mine, yet gold trades at more than double the price. That's partly because gold has that safe-haven status, while platinum's tied to industrial and jewelry demand, which gets hit harder during economic uncertainty. Since 2015, gold and platinum prices have diverged significantly, with gold pulling ahead. This actually creates opportunities though - platinum jewelry has become an attractive alternative for people priced out of gold.

The supply situation is tight too. South Africa, the world's top platinum producer, has been dealing with electricity shortages and railway issues, while Russia (the second largest producer) has its own complications. Meanwhile, demand from the automotive sector has softened due to economic pressures and the rise of electric vehicles that don't need catalytic converters. Throughout 2024, platinum was trading between $900 and $1,100 per ounce despite the supply deficit.

If you're looking at precious metals for your portfolio, understanding the use of platinum across these different sectors really helps with the supply-demand picture. It's not just about price movements - it's about which industries are driving demand and where the bottlenecks are. Definitely worth keeping on your radar if you're serious about commodity investing.
