Last week, the U.S. Treasury hit the debt ceiling. How will markets respond as Congress decides how to move forward? Chief Cross-Asset Strategist Andrew Sheets and Head of Global Thematic and Public Policy Research Michael Zezas discuss.----- Transcript -----Andrew Sheets: Welcome to Thoughts on the Market. I'm Andrew Sheets, Morgan Stanley's Chief Cross-Asset Strategist. Michael Zezas: And I'm Michael Zezas, Head of Global Thematic and Public Policy Research. Andrew Sheets: And on this special episode of the podcast, we'll be discussing the U.S. debt ceiling. It's Wednesday, January 25th at 2 p.m. in London. Michael Zezas: And 9 a.m. in New York. Andrew Sheets: Mike, it's great to be here with you. I'm sure many listeners are familiar with the U.S. debt ceiling, but it's still probably worthwhile to spend 30 seconds on what it is and what hitting the debt ceiling really means. Michael Zezas: Well, in short, it means the government hit its legal limit, as set by Congress, to issue Treasury bonds. And when that happens, it can't access the cash it needs to make the payments it's mandated to make by Congress through appropriations. Hitting this limit isn't about the U.S. being unable to market its bonds, it's about Congress telling Treasury it can't do that until Congress authorizes it to have more bonds outstanding. Now, we hit the debt ceiling last week, but Treasury can buy time using cash management measures to avoid running out of money. And so what investors need to pay attention to is what's called the X date. So that's when there's actually not enough cash left on hand or coming in to pay all the obligations of the government. At that point, Treasury may need to prioritize some payments over others. That X date, it's a moving target and right now the estimates are that it will occur sometime this summer. Andrew Sheets: So I often see the debt ceiling and government shutdowns both used as reference points by investors, but the debt ceiling and government shutdowns are actually quite different things, right?Michael Zezas: That's right. So take a step back, the easiest way to think about it is this: Congress makes separate laws dictating how much revenue the government can collect, so taxes, how much money the government has to spend, and then how much debt it's allowed to incur. So within that dynamic, a debt ceiling problem is effectively a financing problem created by Congress. This problem eventually occurs if Congress' approve spending in excess of the tax revenue it's also approved, that makes a deficit. If, in that case, if Congress hasn't also approved a high enough level of debt to allow Treasury to meet its legal obligation to make sure Congress's approved spending gets done. And if then you also pass the X date, you're unable to fund the full operations of the government, potentially including principal and interest on Treasury bonds. But alternately a government shutdown, that's a problem if Congress doesn't authorize new spending. So if Congress says the government's authorized to spend X amount of dollars until a certain date, after that date, the government can't legally spend any more money with the exception of certain mandated items like principal and interest and entitlement programs. So in that case, the government shuts down until Congress can agree on a new spending plan.Andrew Sheets: So, Mike, let's bring this forward to where we are today in the current setup. How would you currently summarize the view of each camp when it comes to the debt ceiling? Michael Zezas: Well, Republicans say they won't raise the debt ceiling unless it comes with future spending cuts to reduce the budget deficit. Democrats say they just want a clean, no strings attached hike to the debt ceiling because the debate about how much money to spend is supposed to happen when Congress passes its budget, not afterwards, using the government's creditworthiness as a bargaining chip. But these positions aren't new. What's new here ar
