The ABCP market has seen a significant decline since mid-July, attributed to stresses from the U.S. sub-prime mortgage market, causing investors to withdraw and leading to wider interbank spreads. Global ABCP outstandings fell to $1.099 trillion, with conservative investors reassessing their positions and focusing on liquidity and transparency moving forward. Despite the challenges, some investors are beginning to re-engage with ABCP, differentiating riskier programs from those backed by strong liquidity support.
