In the world of global capital-peripheral labour', multiple strategies are employed to accumulate labouring bodies to augment accumulation, the lifeline of capitalism. Relations of inequalities have historically helped capitalism to accumulate and thrive. Growth in India and its accompanied en masse informalisation of labour is located at the intersection of caste, gender and migration. Foregrounding the cultural political economy of agrarian poverty, migration and informalisation of labour, we underline the criticality of caste in reproducing a labour force that is perennially insecure, unsettled and unorganised. Based on a qualitative study in rural Araria, Bihar, we argue that informalisation of labour is institutionalisation of vulnerability, which is sustained and reproduced through caste-based social relations in. Due to the wages in kind, repressive tenancy system and low productivity, indebtedness remains an annual necessity for the lowered caste workers and tillers even when the lowered1 castes move beyond the bounds of the village and into the wider informal economy, their lack of social capital and adverse incorporation in the urban labour market keep them off the benefits of migration and urban growth.
