This day just keeps getting worse.

At the start of trading Monday it looked like Trump was on track to get some kind of ceasefire by now. Instead, we have talk of bombing steel plants and now this.

The Houthis in Yemen say they will enter the conflict on the side of Iran. The possible chokepoint now is the the Bab el-Mandeb Strait, which they could try to blockade. If so, it’s not as devastating as the Strait of Hormuz because the traffic can go through the Suez canal. But it makes the trip significantly longer as the Saudi oil redirected to the pipeline in the Red Sea would now have to travel through the Mediterranean and then around Africa.

Saudi Arabia has also indicated it could enter into the war and that could mean a showdown between the Iran-backed Houthis and Saudi Arabia, who have already been fighting at various levels for 11 years.

With this announcement, we are seeing WTI crude back over $100 as all signs point to escalation rather than ceasefire.

Soon we will start to find out how this is hitting the global economy with gasoline and diesel prices spiking. In places, there are already signs of shortages and I can’t see those improving any time soon.

Update: Some sources still say there has been no statement from the Houthis, so this could be wrong. We will have to sort it out on the weekend.
