Let $X$ be an infinite dimensional Banach space and $T:X\rightarrow X$ be a bounded linear operator. If $T$ is invertible and $\lVert T\rVert_e=\lVert T\rVert$, is it true that (or when is it true that) $\lVert T^{-1}\rVert=\lVert T^{-1}\rVert_e$? Here, $\lVert\cdot\rVert_e$ denotes the essential norm.
