A new vision for global public finance has been long overdue. The concept of GPI comes at the right time, when we urgently need new ideas to shape the future of public finance. Poverty, inequality, fragility and access to food, water and other essential resources remain critical headwinds the world must tackle to become sustainable and stable. None of them can be tackled without adequate financing. They require new international financing mechanisms which build on the past but respond to the future. GPI is an idea whose time has come.
