Banca Monte dei Paschi di Siena SpA will probably fail in its effort to raise 5 billion euros of funds from money managers and individuals as potential anchor investors balk and few bondholders agree to swap their notes into stock, said people with knowledge of the matter. Qatar’s sovereign-wealth fund, which had considered an investment, hasn’t yet committed to buying shares, while a second debt-for-equity swap has raised about 500 million euros through Tuesday, a day before it expires, said the people, who asked not to be identified because the matter is private.
