In Afghanistan, where corruption and ineffective government have hampered efforts to build a functioning state, the Ministry of Finance has been a standout performer. Competently run since as early as 2002, the ministry collects substantial revenue, manages aid inflows, pays public employees, funds key public services and has won the confidence of donors. Now, all that is threatened. The Afghan government is eviscerating the ministry—carving out key constituent parts, putting them directly under the presidential palace, and gravely weakening one of the country’s most effective institutions. It’s a move that’s bad for Afghanistan’s governance and financial viability. It will harm the country’s development and jeopardizes the sustainability of peace if an agreement is reached with the Taliban.
