Since the onset of the Iran crisis, EquiLend Borrow Quantity for WIZZ LN increased from 16.8 million shares to 24.6 million shares, pushing utilization above 95% signalling tighter lendable supply and rising borrow demand. Over the same period, EquiLend Cost to Borrow rose to more than 1500 bps, up from easy to borrow levels of ~30 bps, reflecting increased conviction among short sellers.

The build in loan balance, highly correlated to short interest, comes as European airlines face a dual squeeze: higher jet fuel costs and operational disruption tied to Middle East airspace instability. Wizz Air shares are down around 7% since the start of the crisis, as investors weigh the impact of sustained fuel pressure and signs of delayed booking patterns across the region. While the company has sought to reassure markets that fuel supply remains secure, the stock’s slide suggests growing scepticism around margin resilience in a prolonged high-cost environment.
