When it comes to protecting your assets from inflation, I suppose investing in companies that pay good dividends and are able to cover the inflation in their business model should be a relatively safe bet, as they continue to provide a steady cashflow. If you think the inflation is here to stay and you want to take on more risk, you could take out a loan and leverage that by investing it, as the inflation should cover the interest.
Note that this is NOT financial advice -- I'm anyway not qualified to give that, so take this only as food for thought.
I am leaning more heavily on physical assets as even foreign stocks will suffer to some extent in the event of a dollar crisis. With USD as the current global reserve it's failure will ripple through financial markets and economies around the world.
The best thing you can do is learn how these kinds of things have played out in the past and make a plan to "weather the storm" as it were. I have really been enjoying stories of living through high inflation in other countries on https://www.youtube.com/c/StarPathAcademy. Not saying that is where we are certainly headed but all of the indicators are the same as other high/hyper-inflation periods in history.
