This month, Nigeria was marked by continued fights against corruption, against Boko Haram, and against the country's growing economic crisis. President Muhammadu Buhari announced his intent to have personal control of the country's oil ministry, monitoring the flows of money to ensure theft from the state oil sector is eradicated. The Nigerian army recaptured Gaboru Ngala, one of the Boko Haram bases, this month. Statistics released this month by the International Organization for Migration (IOM) and UNICEF have indicated that recent spikes in Islamic insurgency have resulted in a growth of displaced Nigerians fleeing their homes. This month also marked a year without Nigeria reporting new cases of polio, resulting in the country's removal from the list of polio endemic countries. Segun Odegbami, a Nigerian ex-football player, became the second African to announce his desire to become FIFA President. Members of the United States Special Operations Forces have reportedly began building a border fence across the Nigeria-Niger border to protect against Boko Haram incursions. JPMorgan removed Nigeria from its emerging markets bond index, prompting concerns over the country's foreign exchange liquidity, and resulting in outflows of local bonds and the introduction of a loosened monetary policy. Senate President Bukola Saraki stated this month that Nigeria is combating unprecedented economic crisis, due to reduced oil revenues and a lack of ability on the states' behalf to provide basic services. In order to promote transparency, Buhari also introduced new regulation enforcing all federal institutions to pay their revenues into a single Treasury account.
