Banca Monte dei Paschi di Siena SpA is making a last-ditch effort to raise funds as the prospect of a state rescue looms.
After regulators rebuffed its request for an extension, the world’s oldest bank said it will press ahead with a plan to raise 5 billion euros ($5.3 billion) from investors in the next 19 days. As the odds of attracting fresh investment lengthened, the chance of a government bailout that will impose losses on bondholders grew.
