The surprise announcement Saturday to avoid a shutdown has put some real pressure on McCarthy’s Speakership. McCarthy’s ouster was effectively set in quick motion on Saturday when he pulled off a surprising legislative victory, getting Democrats to join Republicans in approving a short-term funding bill that avoided a government shutdown. While McCarthy pleased the White House with that move, it fueled resentments over his leadership among far-right members of the GOP caucus. 
On Tuesday, The House of Representatives ousted Republican Kevin McCarthy as speaker, the first time in history that the chamber has dethroned its leader in a no-confidence vote.

This is a big event, at least politically. The House has no Speaker and important laws cannot be passed until a new Speaker is in place. 
For now, Republican Patrick McHenry will act as interim Speaker, although his powers are limited to those deemed “necessary and appropriate” to elect a speaker. Such constraints render him a civil servant unable to pass legislation. Given McCarthy's struggle to get elected (15 rounds of voting were needed) and the fact there is no time limit on McHenry’s time in the chair, the process could take quite a while. 
As such, legislative gridlock will likely remain the order of the day until next year’s general election. At one level, not much has changed: Democrats’ control of the Senate means that major bills cannot be passed, while a continuing resolution will keep the government funded for another six weeks. Thereafter, however, the absence of a Speaker means that no government funding bill can be passed, which points to a looming shutdown in late November.
A shutdown should exert a minor drag on the US economy. According to Goldman, a government-wide shutdown would reduce quarterly annualized growth by around 0.2% for each week it lasted after accounting for modest private sector effects. Meanwhile, Bloomberg also speculates that in an extreme tail event, the maximum hit to 4Q GDP would be a drag of 2.8% if the shutdown lasts for the entire quarter. US government debt repayment will be unaffected, for unlike hitting the debt ceiling, a shutdown does not limit the Treasury’s ability to service its obligations.

Even if a shutdown late November would have a minor effect on the economy, the ousting of McCarthy and the looming shutdown could become a negative event for financial markets. The recent rise in bond yields is being driven by 
a lot of factors and political dysfunction is probably one of them. The US debt servicing cost has hit the inflection point for austerity at the same time basic governing is proving to be impossible. And in the event of a shutdown taking place in 45 days, there are several reasons why US equity volatility should rise:

1. The suspension of government spending removes one pillar of economic stability. A government shutdown could raise investors’ doubts on Uncle Sam’s ability to maintain stability in the economy through fiscal spending and government hirings. It would come at a time where other external events are weighing on economic prospects. Indeed, 
   the auto shutdown, declining consumer aid, and rising gasoline prices make the combination of these events more impactful;
2. Data releases from agencies like the Bureau of Labor Statistics, the Census Bureau and the Bureau of Economic Analysis may be suspended during a shutdown. As a reminder, the Fed has repeatedly said it will be data dependent. The fact that the shutdown might result in an information void could leave both the Fed and investors in the dark for a while. 
3. This political crisis is coming at the time where there are fears of an impending US debt crisis. Billionaire investor Ray Dalio is watching closely the “risky” U.S. fiscal situation. 
   “We're going to have a debt crisis in this country” he said earlier this week, adding to US Treasury volatility. Indeed, the US debt servicing cost is increasing for the first time in 35 years. For nearly 20 years, it was effectively free for the US to issue debt as debt service costs were ~1.5%. Now, debt service costs have doubled to 3% and will rise toward 5% as rates skyrocket. To put this in perspective, 5% on $33 trillion is ~$1.7 trillion PER YEAR of interest expense. As deficit spending rises, rates are also rising as the US issues trillions in bonds to cover the deficit. It's a never ending cycle of borrowing to spend which is driving rates higher and leading to interest expense being 20% of US revenue. And there is no long-term plan…
