Adequacy is never sufficient for our reserves; a KS test, although useful, is not a decisive proof if we ignore underlying conditions.
We must anticipate the full expression of risks, not just basic statistical conformity.
If the data used for the KS test does not reflect extreme movements of the currency market, such as during a massive intervention by the Central Bank to support the Real, the similarity is misleading.
Peak performance requires modeling that incorporates our specificities, such as the intrinsic volatility of emerging markets.
A simple test cannot guarantee robustness against liquidity shocks that we manage daily.
