Internal binding between specific groups dilute along a polymer chain plays a paramount role in many technological and biological systems. Against common intuition, we show that the interplay between excluded-volume correlations and hydrodynamic interactions can produce an optimal confinement where the binding is fastest. Similarly, there is an optimal osmotic pressure for the binding rate of a chain immersed in a solution of (non-binding) spectator chains. When internal binding leads to higher-order vertices as in self-assembly, confinement can set the same kinetic rate for the formation of several low-order vertices.
