In distinction, ongoing gridlock might result in larger threat premiums or a shift towards sovereign diversification.
Early indicators are modest however encouraging. Lawmakers have revived talks on a fiscal fee, and the White Home has proven openness to reform. For markets, what issues isn’t the downgrade — it’s the trail ahead. The world nonetheless relies on a financially sound America. Traders might be watching whether or not Washington treats this as a warning — or a chance.
