Which action is NOT necessary when advertising interest rates according to compliance?

In the context of advertising interest rates and ensuring compliance with regulations, making the interest rate and Annual Percentage Yield (APY) equally conspicuous is not a necessary action. The primary focus of compliance when advertising these rates is to ensure clarity and transparency. The regulations dictate that requirements such as providing the current interest rate and spelling out "Annual Percentage Yield" at least once are essential to convey accurate information to consumers.

The need for both the interest rate and the APY to be conspicuous is less emphasized than ensuring that each component is correctly represented and easily understood. While it is important for consumers to see both rates, the requirement does not mandate that they must be equally prominent in the advertisement. This means that while delivering accurate rates and transparent terms is vital, equal prominence is not a strict compliance requirement, thus making this action unnecessary in the context of compliance.
