The 2013 H1 report covers sterling money market transactions that took place during May 2013. The total value of reported transactions and conditions in the sterling money market were broadly unchanged relative to the previous survey in November 2012. Secured transactions continued to make up a large share of total transactions (69% of the overall money market). As in previous surveys, activity was concentrated at overnight maturities. Perceptions of the functioning of the unsecured sterling money market improved slightly, but remained significantly less positive than those of the secured market.
