This is what we said back in early March when the BTFDers were hoping WTI in the low $40s would never again be seen:

Come June, when all available on-land storage is exhausted, each incremental barrel will have to be dumped on the market forcing prices lower and inflicting further pain on the entire US shale complex (just as Q1 results are released which will invariably show huge writedowns as companies will no longer be able to hide behind the SEC-mandated accounting trick that made Q4 results appear respectable). Here's Soc Gen:  "...oil markets can be impatient and prices could drop considerably lower. As we have written previously, we are currently more concerned about downside risk than upside risk."

Since then, as expected, crude tumbled to new post-Lehman lows, confirming the global deflationary wave is raging (for more details please see China), and WTI only posted a rebound on quad-witching Friday as another algo-driven stop hunt spooked all those who were short the energy complex.
