It is a misconception that fixed income literally means fixed returns. Investors have been historically sold fixed income products in such a manner ie. with a promise of fixed returns and capital safety. However, there are myriad types of fixed income products which feature at various points along the risk/return spectrum. It is imperative for investors to understand this because when expectation does not meet reality, there is dissonance and discontent. Investors have faced this perceived breach of trust as recently as September 2018, when the AAA rated bonds of a certain corporate were downgraded to default rating in a matter of weeks. This had a cascading impact on the market. The liquidity conditions were poor and there was a general run on funds, making things even worse. Rating agencies got into action and there have been several more downgrades than upgrades since September 2018.
