Just been looking into platinum and honestly there's way more to understand about this metal than I initially thought. Most people hear platinum and think jewelry, but the real story is much deeper when you look at actual use of platinum across different industries.

So here's what caught my attention - platinum is the third most-traded precious metal globally, sitting behind gold and silver. But the demand picture is fragmented across multiple sectors, which makes it interesting from a supply-demand perspective.

The biggest driver? Autocatalysts. These are the ceramic honeycomb structures coated with platinum that sit in your car's exhaust system. They convert over 90% of harmful emissions into less harmful compounds. Been around since the 1970s and now almost every new vehicle has one. The automotive sector was pulling in around 3.17 million ounces of platinum back in 2024, and it's expected to stay strong. As emission standards get tighter, this demand isn't going away.

Then there's jewelry, which is the second major use of platinum. The metal's got some solid properties - it's durable, doesn't tarnish, and can handle repeated heating without degrading. China's the biggest market for platinum jewelry. Demand there was tracking around 1.95 million ounces in 2024.

What really blew my mind though is the industrial applications. Platinum's used in fertilizer production, electronics, hard drives, dental work, glass manufacturing, and sensors. It's also critical in medical devices - catheters, stents, and even cancer drugs like cisplatin. Medical demand has been climbing, hitting over 300,000 ounces annually.

Now for the market dynamics - platinum's been trading between $900-$1,100 per ounce recently. Interesting thing is platinum's actually 30 times rarer than gold, yet gold's been trading at more than double the price. This disconnect happened around 2015 when the two metals diverged. Gold's got that safe-haven appeal during uncertain times, while platinum's tied to industrial and automotive demand, which tanks when economies struggle.

The supply side is tight too. South Africa's the top producer but dealing with electricity and rail issues. Russia's second but obviously facing geopolitical headwinds. Meanwhile, the automotive sector has been under pressure from economic slowdowns and the EV shift (EVs don't need catalytic converters, so less platinum demand there).

If you're thinking about precious metals, the use of platinum in real industries versus just store-of-value makes it worth understanding. Both gold and platinum have their place depending on what you're looking for, but platinum's industrial fundamentals are definitely worth watching.
