Around 130 countries, including all G20 nations, agree to a global tax deal, aimed at world's 100 biggest companies and setting minimum corporate rates at 15%
That breadth matters because a minimum rate only works if tax havens can't opt out; with nearly the whole negotiating universe signed on, the holdout arbitrage shrinks. The open question is ratification — as later coverage of the expanded 136-country version still awaiting G20 approval shows, agreement on paper and enacted law are different stages.
First-order effects
The world's 100 biggest companies — the deal's named target group — face a floor under their effective tax rates wherever they book profits, ending race-to-the-bottom pricing on their tax bills.
Low-tax jurisdictions that built revenue models on undercutting other sovereigns now have to compete inside a 15% band rather than below it.
Second-order effects
Countries that hosted profit-shifting structures lose their main lever for attracting corporate bookings, pushing them toward subsidies and infrastructure incentives instead of headline rates.
Multinationals' tax departments shift focus from exploiting rate gaps between countries to managing compliance across a near-universal rule set — a cost center rather than a savings engine.
Third-order effects
If implementation holds through G20 approval and national legislation, corporate taxation reorganizes around where value is created rather than where profits are booked — a structural reversal of decades of tax competition.
The 2019-to-2021 sequence shows tax policy converging through plurilateral blocs (G7 setting terms, G20 scaling them) rather than slow universal treaties, a template likely reused for other cross-border rules.
The trend: Corporate taxation is moving from unilateral rate competition toward a coordinated multilateral floor, with the G7 drafting and the G20 ratifying what individual states then enact.
Today is an historic day for economic diplomacy. For decades, the United States has participated in a self-defeating international tax competition, lowering our corporate tax rates only to watch other nations lower theirs in response. The result was a global race to the bottom:

130 economies support the global minimum corporate tax of 15%. 9 do not: Ireland, Hungary, Estonia, Barbados, Saint Vincent & Grenadines, Kenya, Nigeria, Peru and Sri Lanka. Good news, but without sanctions on the 9, I don't see how this could succeed. https://www.oecd.org/...

Who could lower their corporate rate further & faster? No nation has won this race. Lower tax rates have not only failed to attract new business, they've also deprived countries of funding for important investments like infrastructure, education, & efforts to combat the pandemic.

In its place, America will enter a competition that we can win; one judged on the skill of our workers & the strength of our infrastructure. We have a chance now to build a global & domestic tax system that lets American workers & businesses compete and win in the world economy.

In the United States, this agreement will ensure that corporations shoulder a fair share of that burden. Today's agreement by 130 countries representing more than 90% of global GDP is a clear sign: the race to the bottom is one step closer to coming to an end.
