Markets are bracing for a "late-night fireworks" event following today's US CPI report, but what if half the market decides not to attend the subsequent "victory celebration"? This is something to keep in mind as we head into tomorrow. Wednesday (November 11th) is a partial market closure for Veterans Day in the US, making this timing particularly awkward given to the CPI report later today. The US bond market will be closed tomorrow, but the NYSE and Nasdaq will trade as usual. However, this doesn't mean everything on Wall Street will remain the same.

Declining participation: Absence of major banks and fixed income trading desks may indicate insufficient market confidence.

Wednesday is a partial market closure for Veterans Day in the United States, a timing that is particularly awkward given the CPI report scheduled for later today. The U.S. bond market will be closed all day, and while the NYSE and Nasdaq will continue trading as usual, this doesn't mean Wall Street will remain unchanged. Major banks and key fixed-income trading desks will cease operations, leading to a significant drop in market participation. In this environment, the confidence underlying any sudden volatility is likely to be weaker—especially after traders have just digested the latest U.S. inflation data. If inflation data only affected the stock market, the situation would be relatively simple; however, in reality, U.S. Treasury yields are often at the heart of market reactions and quickly transmit to the dollar, stocks, and broader risk sentiment. When the bond market is removed from the equation, the market suddenly lacks one of the biggest drivers of price discovery and sentiment measurement. The initial reaction to the CPI may accurately reflect the data shock, but its "persistence" lacks a crucial testing ground—the bond market. Traders therefore need to be aware that any price movements on Wednesday may appear "lacking in confidence" due to insufficient participation.

The dual effects of scarce liquidity: momentum is hard to sustain, but volatility may be amplified.

For traders, this special trading day carries a double effect. If today's CPI report delivers a major surprise, the initial reaction could extend into Wednesday; however, in the absence of meaningful participation from the US Treasury market, subsequent momentum is often difficult to sustain. The advance of either bulls or bears is more likely to come to an abrupt halt in a illiquid environment. Meanwhile, illiquidity does not necessarily mean less volatility; it can actually amplify price swings. When large orders appear and the market lacks sufficient buyers or sellers to cover them, prices may experience sharp and directionless fluctuations. Therefore, one should not be overly surprised if Wednesday sees trading without a clear direction, sudden but unsustainable fluctuations, or prices repeatedly trading within a narrow range. This is not a complete representation of the market narrative, but rather a technical phenomenon caused by the absence of participants.

The real test comes on Thursday: a reassessment of the inflation narrative after the bond market retraces.

A greater test will come on Thursday. The bond market will reopen, allowing traders to reassess the narrative shaped by inflation data with greater participation and a more complete price discovery mechanism. Only after the bond market reopens can the market truly test the lasting impact of CPI on yields, the dollar, and risk assets. Therefore, it's unwise to overinterpret Wednesday's price movements before Thursday. Wednesday's market action may simply be an initial reaction to the data shock, not the final conclusion. Sometimes, market hesitation or lack of direction is merely due to "fewer people in the room." Truly meaningful pricing and position adjustments often occur after liquidity recovers and major participants return. Traders should view Wednesday as a transitional day and Thursday as a crucial window for recalibrating expectations and positions.

in conclusion

Wednesday is a partial market closure for Veterans Day. The bond market is closed, while the NYSE and Nasdaq remain open. However, the absence of major banks and key fixed-income trading desks may reduce participation and confidence. The initial CPI reaction may extend into the following day, but without participation from the US Treasury market, subsequent momentum will be difficult to sustain. Thin liquidity could also amplify price swings, leading to volatile, directionless, or unsustainable sudden fluctuations. The real test will come on Thursday—after the bond market reopens, allowing traders to reassess the inflation narrative with greater participation. Until then, it's unwise to overinterpret tomorrow's price action, as the market may not be telling the full story—sometimes, it's simply because there are fewer people in the room.
