A Romanian political crisis is once again testing the country’s managed float currency regime, with the central bank allowing the leu to weaken to record lows this week.

The leu slid 0.8% against the euro on Tuesday — one of the biggest drops among emerging-market currencies — as lawmakers voted to bring down the administration of Prime Minister Ilie Bolojan following coalition clashes over painful austerity measures. A year ago, the central bank also let the leu drop during turmoil surrounding a presidential election.
