War is still exacting a heavy toll on Ukraine’s economy. The country’s GDP is a quarter smaller than on the eve of Vladimir Putin’s invasion, the central bank is tearing through foreign reserves and Russia’s recent attacks on critical infrastructure have depressed growth forecasts. “Strong armies”, warned Sergii Marchenko, Ukraine’s finance minister, on June 17th, “must be underpinned by strong economies.”

Following American lawmakers’ decision in April to belatedly approve a funding package worth $60bn, Ukraine is not about to run out of weapons. In time, the state’s finances will also be bolstered by G7 plans, announced on June 13th, to use Russian central-bank assets frozen in Western financial institutions to lend another $50bn. The problem is that Ukraine faces a cash crunch—and soon.
