I don't think this situation is as complex as some would have you believe.
1. Due to a bunch of different factors -- the war, the credit fiasco, monetary policy, etc -- the US dollar is collapsing (not "is going to collapse" -- it's already started).
2. The US has been in a recession for some time.
3. Declining prices are unlikely. Bernanke has written and spoken extensively about this. He has said, in no uncertain terms, that he won't allow that to happen to any significant degree.
The cure for declining prices is inflation. One mechanism for inflation is the lowering of interest rates. Lower interest rates further damages the dollar.
Another reason why I believe #3 is that as the dollar collapse continues, foreign holders of dollars will continue to dump them -- one way they do that is by buying US assets, like businesses, skyscrapers, land, etc. The result is even more inflation. So much so, in fact, that hyperinflation (>50% per year) is the real risk.
As a result of #1 above, stocks, bonds and banks are bad places to have your money. Even money market funds are at risk. Real estate in the US is also likely to continue to decline in value for some time.
Good places to have your money are in hard assets such as metals and commodities like wheat, corn and natural gas -- you can think of them like hedges against what you pay for food. They have been going up steadily even though the stock market is dropping. I like gold better than silver because it's not as bulky, though an argument can be made for both. Bullion coins like the Maple Leaf are best (lowest margin over gold content), though there are some vaulted storage companies that are also very good (I'm partial to
BullionVault, who also will give you about $20 worth of gold when you open an account).
You might also consider foreign currencies. Commodity currencies like the Canadian, Australian and New Zealand dollars should be stronger that the US dollar. The Swiss Franc and the Euro should also do well. If you can swing an account in NZ (where I live), interest rates on basic savings accounts here are close to the highest in the industrial world, at 7.6% or so. 9% is easily achieved in reliable commercial bonds.
For the person who was asking about their 85 yr old relative. If it was me, I would take the 100K from the CD when it matures and buy 100+ gold Maple Leaf coins with it. Keep a few thousand cash out in reserve and to live off of. When more cash is needed, sell a coin. Or you can do an equivalent thing with a company like
BullionVault if dealing with coins is too much of a hassle. The problem with another CD is that price inflation is currently 12%+/yr, so she's really losing money. Gold has a better chance of retaining purchasing power than cash. Yes, it might go down before it goes up, but *that doesn't matter*. It could also double before it goes down. The certainty here is that the dollar will continue to go down.
