Classic finance theory dictates that investors are rewarded with a higher interest rate when they take on more risk. For example, even in today's.

That risk can be measured. Most work on risk assumes that historic nominal before adjusting for inflation volatility of the stock market price or the historic correlation beta of an individual stock with the market are good measures of risk. Beta may capture the market related risk and under CAPM that is the only risk that matters since all other risk can and should be diversified away.

But studies have shown that beta varies over time, therefore it is not clear that beta can be actually measured.

And calculations of beta vary dramatically depending if one works with monthly, daily, weekly or annual returns. And if one believes that diversifiable risks are also relevant then it is clear that those cannot be so easily measured.

For example treasury bills are not risky in the short term but putting all funds into Treasury bills would cause a large risk of insufficient long term purchasing power, as the returns barely keep up with inflation.

The government is unlikely to default on its debtDebt Money that you have borrowed. You must repay the loan, with interest, by a set date. At the other extreme, common shares are very risky because they have no guarantees and shareholders are paid last if the company is in trouble or goes bankrupt.
