Bulker values are rising by several million dollars each week, according to analysts, due to surging time charter rates and sales concluded at ever-firmer prices.

Clarksons Platou Securities said on Monday that sale-and-purchase (S&P) transactions for capesize, panamax and ultramax bulkers had prompted it to increase its asset-value estimates.

Five-year-old capesizes are now assessed by Clarksons Research Services at $33m, up by 10% from $30m last week.
