Regarding oil prices you don't have to look further than the good old USA trying to damage Russia's economy, quite simply if you don't get your way like the Ukrainian and Syrian conflicts you retaliate by damaging their economy.
Saudi Arabia is the US love child and has to do as told, I had posted an article not long ago relating to this fact.

We don't have to look too far back in history to see Saudi Arabia, the world's largest oil exporter and producer, using the oil price to achieve its foreign policy objectives. In 1973, Egyptian President Anwar Sadat convinced Saudi King Faisal to cut production and raise prices, then to go as far as embargoing oil exports, all with the goal of punishing the United States for supporting Israel against the Arab states. It worked. The “oil price shock” quadrupled prices.

It happened again in 1986, when Saudi Arabia-led OPEC allowed prices to drop precipitously, and then in 1990, when the Saudis sent prices plummeting as a way of taking out Russia, which was seen as a threat to their oil supremacy. In 1998, they succeeded. When the oil price was halved from $25 to $12, Russia defaulted on its debt.

The Saudis and other OPEC members have, of course, used the oil price for the obverse effect, that is, suppressing production to keep prices artificially high and member states swimming in “petrodollars”. In 2008, oil peaked at $147 a barrel.

“What is the reason for the United States and some U.S. allies wanting to drive down the price of oil?” Venezuelan President Nicolas Maduro asked rhetorically in October. “To harm Russia.”

Many believe the oil price plunge is the result of deliberate and well-planned collusion on the part of the United States and Saudi Arabia to punish Russia and Iran for supporting the murderous Assad regime in Syria.
