It would not work. The oil markets know that releasing oil from the strategic oil reserve is temporary and not sustained and they are not going to drop the oil price in any significant way because of this.
It doesn’t have to work well. A massive release will drop the price enough that the population will feel relief far in excess of reality and will credit the kenyan with it. The tiny release last year accomplished that much. It was only temporary but, hey, it only has to last until the day after the election. Last years release was surely a test run.
