Variable Storage Rates (VSR)

Variable Storage Rates (VSR) is a market-based determinant of maximum allowable storage charges for outstanding wheat shipping certificates. It triggers higher maximum allowable storage charges that allow wider spreads when spreads are near financial full carry and lower maximum allowable storage charges when spreads are narrow or inverted. Market participants may follow the daily VSR calculations during the observation period at the "VSR Calculator" link below.

For Chicago SRW Wheat Futures:

Nearby spreads that average 80 percent of financial full carry or greater will trigger an increase in maximum allowable storage charges by 10/100s of one cent per bushel per day (approximately 3 cents per bushel per month) following the nearby delivery period. Conversely, nearby spreads that average 50 percent of financial full carry or less will trigger a decrease in maximum allowable storage charges by 10/100s of once cent per bushel per day following the nearby delivery period. Should nearby spreads average over 50 percent of financial full carry and less than 80 percent of financial full carry, the maximum allowable storage charges will remain the same as in the previous period. There is no upper limit for maximum allowable storage charges under VSR, but the minimum rate is 16.5/100s of one cent per bushel per day.

Beginning September 19, 2016, the maximum allowable storage charge increased from $0.00265 to $0.00365 per bushel per day and remains at that level.

For KC HRW Wheat Futures:

The May 2018 – July 2018 calendar spread averaged 93.90 percent of financial full carry during the period of March 19, 2018 through April 20, 2018. Since this result falls above 80 percent of financial full carry, the maximum premium charge that a KC HRW Wheat regular delivery facility may charge holders of its outstanding shipping certificates will increase from the current maximum charge of 26.5/100s of one cent per bushel per day (approximately 8 cents per bushel per month) to 36.5/100s of one cent per bushel per day (approximately 11 cents per bushel per month) on May 18, 2018.

The next evaluation period for both contracts will measure the July 2018 – September 2018 calendar spread relative to financial full carry during the period of May 21, 2018 to June 22, 2018 with the next possible adjustment to contract premium charges on July 18, 2018.

Beginning May 19, 2018, the maximum allowable storage charge will increase from $.00265 to $.00365 per bushel per day.
