Royal Caribbean Cruises is borrowing $700m from five banks to pay for most of its two-thirds stake in Silversea Cruises.

The Miami-based cruise major in mid-June acquired 66.7% of the luxury and expedition cruise operator for $1bn.

The loan is being drawn against JPMorgan Chase Bank, Bank of America, Citibank, Goldman Sachs Bank and Morgan Stanley Bank, according to a regulatory filing.
