Is a Roth IRA considered a liquid asset?

Good day, I have a question regarding the categorization of financial assets. Specifically, I'm wondering if a Roth IRA is typically considered a liquid asset or not. Liquid assets, as I understand, are those that can be quickly converted into cash with minimal loss of value. Could you please clarify whether a Roth IRA falls into this category? Additionally, what factors, if any, would impact this determination? Thank you for your assistance.
