There appears to be widespread support for a global minimum corporate tax rate of 15%.
From CNBC:
Treasury Secretary Janet Yellen announced Thursday that a group of 130 nations has agreed to a global minimum tax on corporations, part of a broader agreement to overhaul international tax rules.
If widely enacted, the GMT would effectively end the practice of global corporations seeking out low-tax jurisdictions like Ireland and the British Virgin Islands to move their headquarters to, even though their customers, operations and executives are located elsewhere.
Conclusion
We expect a global minimum tax on corporations of 15% to be passed and are adjusting our valuation models to ensure that all earnings projections include a minimum tax rate of 15% on international income.
