Oil by reaching above $64 per barrel on 16 Feb 218.

This chart correlates heavily with that of the value of the Japanese Yen. This is why we see a deep dive for Yen as it has less supply. Thus, a strengthened Yen against the USD. This is probably why Oil prices increased sharply as it was due to the weakened USD. In the eyes ot 1 OPEC this would be called price stabilization efforts. Although I see them as a clone between Bitcoin Private, and Bitcoin core. So far prices have remained stable in favor of KSA.
