Yield to maturity is far different that yearly yield.

though it is possible to find some bonds that have an annual yield of 8%. Though no one would expect them all to make it maturity without any credit issues.

You can find a very few. But they are limited in some way, and almost always government-funded.

iBonds hit above 8% return in a year if you bought at just the right time this year, IIRC.

Of course, if you calculate real return then you will have a sad.

There’s also a very real counterparty risk in bonds that need to give 8%.

Inflation bonds are kind of an exception there, since if inflation is 8% the market should be doing much better than that on average.

Are they Venezuela or Zimbabwe?

US federal funds rate hit 19.39 percent in April 1980. As a result long-term state bond did very well for their owners as inflation came down. My mom told stories about "Massachusetts Nines" with legendary 9% yields.

Utilities and co-ops issued ~15% paper which also did extremely well for those who purchased it in the early 80s.

Sure, back then. But I’m guessing these are not 50+ year maturities still paying out.

Know offhand what the 30-year yielded back in '80?

For reference, the 30 is now at about 100bp less than shorter treasuries:
