Which of the following money market instruments is considered the most liquid?  A. Certificates of Deposit (CDs)  B. Commercial Bills  C. Treasury Bills (T-Bills)  D. Call Money

The most liquid money market instrument among the options given is C. Treasury Bills (T-Bills).

Here's why:

Liquidity refers to the ease with which an asset, or security, can be converted into ready cash without affecting its market price. The most liquid assets are cash and securities that can be sold immediately at a stable price.

A. Certificates of Deposit (CDs) are time deposits with banks. They have a fixed maturity date and a specified interest rate, and can be issued in any denomination. However, they cannot be withdrawn on demand and hence are less liquid.

B. Commercial Bills are short term, negotiable, and self-liquidating instruments used in trade financing, and while they are quite liquid, they are not as liquid as T-Bills.

C. Treasury Bills (T-Bills) are short-term securities that mature in one year or less from their issue date. They are issued by the government to finance their short term expenditure. Being backed by the government, they are considered risk-free. They are highly liquid as they can be readily sold in the secondary market at any time.

D. Call Money is a short term finance repayable on demand, with a maturity period of one day to fifteen days, used for inter-bank transactions. They are liquid but not as much as T-Bills.

So, Treasury Bills (T-Bills) are considered the most liquid among the options given.
