#### Abstract

Let $X$ be a compact connected Riemann surface of genus $g \geq 0$, and let $\mathrm{Sym}^d (X), d \geq 1$, denote the $d$-fold symmetric product of $X$. We show that $\mathrm{Sym}^d (X)$ admits a Hermitian metric with

(1) negative Chern scalar curvature if and only if $g \geq 2$, and

(2) positive Chern scalar curvature if and only if $d \gt g$.
