Thanks. That's why I started to read this thread.

FCB ? equals Foreign Central Banks?

I was taught that (91-day) T-Bills are the risk-free interest rate. I'm sure some here believe gold is "risk-free".

If T-bills are no longer risk free, then that changes all options measures by Black-Scholes. Options would be mis-priced at Black-Scholes levels.

Aside from inflation risk and currency risk, what is not risk-free about 91-day U.S. T-Bills, when held to maturity? Are major banks paying 5.20% (but only on up to $99,999.99, such as Bank of America, online only even now) for 4 months "more" risk-free?
