According to the online news of the securities times, Sealand Securities Co.Ltd(000750) believes that the causes of the current round of oil price breaking 100 are similar to those in 2011. The risk of supply interruption caused by geopolitical conflict is the main reason for the rapid rise of international oil price. The improvement of demand expectation also intensifies the market’s concern about the prospect of supply and demand, but considering that there is more room for maneuver for sanctions on oil and gas The promotion of the Iran nuclear agreement has played a certain role in easing the tight situation of crude oil supply. Superimposed on the inhibitory effect of the sharp rise of the US dollar index on bulk commodities, the basis of the continuous rise of oil prices needs to be observed. However, the market has strong concerns about stagflation, which suppresses risk appetite to a certain extent. The subsequent market rebound needs to wait for the obvious easing of stagflation concerns. After the current round of oil price breaks 100%, it has a certain driving effect on the commodity market, and the short-term or volatility of the bond market intensifies.
