Does anyone know why the cash reserve has to increase? I don’t get the explanation.
i would argue that with monthly averages you have a similar effect to the smoothing rule - as such even if assets increase or decrease significantly in any month, it’s just 1/12th of the total impact and as such you need lower liquidity as uncertainty is removed.
the annual setting - you could face a very strong unexpected December and for that reason you have to hold a high cash reserve throughout the 4 th quarter.
