This story does not have two clearly opposing sides.
Financial conditions in Mexico can tighten a little more, even if Banxico is not moving the rate, because the long end adjusts with the United States. It is something that appears to be entering the Board's analysis.
The US fiscal fundamentals have not changed and as long as the Federal Reserve does not clearly demonstrate that it will maintain a rate-hiking cycle to reduce inflation, the market will continue to demand additional compensation for holding long-term instruments.
