This species is listed as Data Deficient because it is known from only two specimens and a limited number of recent sightings, thus there is insufficient information available for assessment of its threat status.

|Range Description:||Carpodacus sillemi was described from two specimens collected in 1929 on a barren plateau at 5,125 m in southern Xinjiang Autonomous Region, China (in an area under Chinese administration but also claimed by India). One of the birds collected was a juvenile with wings not yet fully grown and the collector considered that the birds had either bred close to where they were collected or on the nearby peaks in the Kunlun Shan range. In 2012 it was rediscovered c.1,350 km. away from the type locality in the Yeniugou Valley, in a remote area of western Qinghai, China (Kazmierczak and Mizuka 2012), with further sightings the following year in the Yeniugou Valley (Mizuka 2014). During the 2013 survey the species was not located anywhere apart from in the Yeniugou Valley (Mizuka 2014), and searches elsewhere have failed to find the species (Mizuka 2014, J. Hornskov in litt. 2016). However, the survey did conclude that even at appropriate altitudes the species was very difficult to locate (Mizuka 2014), and so it is presumably localised and scarce.|
