We identify the unique role of the government bond lending market in collateral transformation during periods of market stress. Using a novel database, we provide evidence that safe assets in the lending market have higher demand, higher borrowing cost, and higher usage of non-cash collateral relative to non-safe assets during stressed market conditions. Moreover, we find that market participants are able to obtain safe assets using relatively low-quality non-cash collateral, allowing for collateral transformation. We show that policy interventions by central banks can help reduce safe asset shortages by returning sought-after safe assets to the market.
