Transurban chief executive Scott Charlton says no one should be surprised that interest rates are going up, arguing that the tollroad group is well-prepared for a rise in inflation.

“I’m surprised if anyone’s surprised that interest rates are rising or inflation is gathering pace because it’s only a matter of time in the cycle and we’ve been preparing for it for years,” Mr Charlton told The Australian Financial Review after the company reported an interim net loss of $103 million.
