The document discusses the potential impacts of the ongoing US political deadlock over the budget and debt ceiling. It notes that while a government shutdown will likely only reduce US GDP growth slightly and temporarily, failure to raise the debt ceiling could be catastrophic and lead to US default. This could cause a loss of confidence in the US dollar as a reserve currency. However, the analyst expects Congress will approve a new budget and raise the debt ceiling to avoid such consequences in the short-term. Nevertheless, continued political uncertainty may still damage confidence and the credibility of the US dollar in the long-run.
