Some experts said an 鈥淥asis bump鈥 could have contributed to higher accommodation prices in July.

The rate of Consumer Prices Index (CPI) inflation is widely expected to have increased to 3.7% in July, from the 3.6% recorded in June.
The school summer holidays are likely to have seen airfares rise considerably, with airlines typically bumping up prices in July amid stronger demand from families.

Meanwhile, economists have pointed to a possible spike in hotel prices helping drive up CPI inflation in July.
Sanjay Raja, senior economist for Deutsche Bank, said this could partly be attributed to British band Oasis kicking off their reunion tour in July.
The concerts brought in hordes of fans to arenas in Cardiff, Manchester, London and Edinburgh, which could have driven greater demand for hotel rooms.
