What is money as a sterile asset?

Money as a sterile asset refers to the concept that money itself does not generate any income or yield; it merely serves as a medium of exchange, a unit of account, and a store of value. Unlike investments such as stocks or real estate, which can appreciate or produce returns, money held in cash or cash-equivalent forms simply retains its nominal value over time. This notion highlights the opportunity cost of holding cash, as it may not keep pace with inflation or provide growth compared to other asset classes. Essentially, while money is essential for transactions, its lack of productive capacity makes it a less favorable option for long-term wealth accumulation.
