Palladium in IRA - Anyone actually doing this?

• •Thinking about diversifying my precious metals IRA beyond just gold and silver, and palladium keeps coming up.
• •I’ve currently got about $750k in my IRA, a good chunk of that (~20%) in physical gold I moved over a few years ago.
• •The rest is in a mix of stocks and bonds, but I'm always looking at how global events, especially out here in the Pacific, could impact things.

Thinking about diversifying my precious metals IRA beyond just gold and silver, and palladium keeps coming up. I’ve currently got about $750k in my IRA, a good chunk of that (~20%) in physical gold I moved over a few years ago. The rest is in a mix of stocks and bonds, but I'm always looking at how global events, especially out here in the Pacific, could impact things. Been retired from the Navy for a decade now, and still keep a close eye on the geopolitical chessboard.

Palladium’s industrial uses, particularly in autos and electronics, seem like a solid play. With tightening emissions standards globally, especially in places like China and India (which are huge markets out here in our sphere of influence), catalytic converters aren't going anywhere. But it’s also a much smaller market than gold or silver, which makes me a little nervous about liquidity if I ever needed to sell a significant chunk.

Has anyone here actually added palladium to their precious metals IRA? Was it worth the extra effort in terms of sourcing and storage? I understand the premium can be higher, and I'm not looking to dump my gold holdings, just maybe allocate 5-10% of my metals portfolio to something with a bit more industrial upside. Or am I just overthinking it and should stick to the tried and true?

Mahalo for any insights!
