Is being stingy a mental disorder?

Narcissistic Personality Disorder

Individuals with Narcissistic Personality Disorder (NPD) often exhibit stingy behavior and a lack of generosity. Interestingly, they tend to be quite lavish when it comes to spending on themselves. In contrast, those with Obsessive-Compulsive Personality Disorder (OCPD) typically hoard their money and demonstrate miserliness not only towards themselves but also towards others.
