Quote from PAPA ROACH:
Oct/Nov crosses seasons, (injection in Oct/withdrawal in Nov), and is more volatile than a intra-seasonal spread. The seasons are Injection wich is April through Oct, and withdrawal which is Nov through March. You will notice that one of the most historically volatile spreads is the March/April. If there is any chance of supplies running too low by winters end, you could see a massive price response in March as it would be the month that storage could run out.
With our over-supply, we may run out of actual storgae space before we get into withdrawal season, which would crater prices. I actually think this is a very real scenario and therefore Oct could fall ubruptly relative to Nov as excess cash has nowhere to go.
The only way of possibly avoiding this scenario is to take prices down alot, and do it now, so we price enough production off and attract enough coal to gas switching to avoid this.
