Re-Active destocking in supply chain management is a reduction of the inventory when expected demand goes down. When a company is only doing Re-Active destocking the desired inventory to sales ratio, remains unchanged. Re-Active destocking in general is done by operational managers of the logistical activities, without additional instructions. The inventory can include finished products, raw materials and/or goods in process. The term Re-Active destocking is relevant when it is used in connection with active destocking. Active destocking refers to an active decision to reduce the inventory to sales ratio〔 of a company. In general Active destocking is done following an autonomous, often financial decision by a company to improve its efficiency, freeing up cash and reducing its costs. Decisions for Active destocking in general are made by financial executives or general managers. The terms Re-Active destocking and active destocking were first used in an article about the Lehman Wave, published by Dutch researchers in 2009.〔(【引用サイトリンク】url=http://beta.ieis.tue.nl/node/1502 )〕 A Lehman Wave refers to an economy-wide fluctuation in production and in economic activity with a wavelength of between 12 to 18 months, driven by a sudden major disruption of the economic system. The Lehman Wave is a dampened, wave-like fluctuation around equilibrium. The amplitude of the Lehman Wave is larger for a business that is further away from its end market than for a business that is closer to its end market, which difference is caused by cumulative destocking of the intermediate supply chain. The first described Lehman Wave was caused by global active destocking, followed by Re-Active destocking after the financial panic following the bankruptcy of Lehman Brothers on September 15, 2008. The Lehman Wave can have strong effects on the sales volume and therefore on the profitability of companies higher in the value chain. ==Active destocking caused the Lehman Wave and Re-Active destocking deepened it== The strong dip in the manufacturing industry seen at the end of 2008 was caused by cumulative and synchronized active destocking followed by Re-Active destocking, triggered by the bankruptcy of Lehman Brothers. Said bankruptcy created a sudden peak in the Libor interest rate, causing the banks to recall credit and companies to start freeing up cash by Active destocking, so reducing their stocks. When the customers of a company start Active destocking it is experienced by said company as lower demand and said company will respond by doing Re-Active destocking. End markets also responded by going down, but slower and in most markets not so strongly. The drop in end market plus the Active and Re-Active destocking created a giant damped wave, the so-called Lehman Wave.
