Whether that is a big a problem is not clear. It could matter, for example, through the cost of capital to the productive side of the economy, as investors price the illiquidity of the assets they buy. This would mean that borrowers pay a little more than otherwise as a result.
But are creditworthy borrowers actually having material difficulties accessing finance on reasonable terms, beyond what is explainable by their own macroeconomic fundamentals? It also seems that liquidity is somewhat less reliable even under conditions that could be thought to be “normal”, even in some of the largest sovereign markets in the world.
