January’s market action often matters more than simply marking the opening of the calendar year. Institutional positioning resets, testing of economic assumptions, and early price moves reflect how market participants interpret the first meaningful signals of the year.
While January rarely determines full-year outcomes, it frequently shapes the narratives markets carry into the first quarter (Q1).
Four critical levers: growth, labour, inflation, and policy, can provide an early indication of how markets are processing and prioritising incoming information.
Growth: manufacturing PMIs

January’s first growth test comes from the manufacturing surveys, with markets watching whether signals from S&P Global Manufacturing PMI and ISM Manufacturing PMI tell a consistent story.
Key dates:
- ISM Manufacturing PMI: 5 January, 10:00 AM (ET)/ 6 January, 1:00 AM (AEDT)
What markets look for:
Attention often centres on new orders as a forward-looking indicator of demand, alongside prices paid for early insight into cost pressures.
Broad strength across both surveys would support the narrative that the growth momentum seen toward the end of 2025 may extend into early 2026, easing some concerns about a sharper slowdown. Weaker or conflicting readings would keep the growth outlook uncertain, rather than decisively negative.
How it tends to show up in markets:
Firmer growth signals often appear first in higher short-dated Treasury yields. Rising yields can tighten financial conditions, weigh on equity valuations, and support the USD, with spillover effects across foreign exchange (FX) and commodity markets.
Labour: job openings and payrolls

While early-January Non-Farm Payrolls (NFP) often drive short-term volatility, JOLTS job openings may be more influential in shaping January’s policy narrative.
Key dates:
- JOLTS Job Openings: 7 January, 10:00 AM (ET)/ 8 January, 1:00 AM (AEDT)
- Non-Farm Payrolls (NFP): 9 January, 8:30 AM (ET)/ 10 January, 12:30 AM (AEDT)
What markets look for:
Markets often treat JOLTS as a clearer indicator of underlying labour demand than month-to-month hiring flows.
A continued drift lower in openings would support the view that labour demand is easing in an orderly way, reinforcing confidence that inflation pressures can continue to moderate. A rebound or stalled decline would suggest labour conditions remain firmer than expected.
Market sensitivities:
For markets, easing labour demand typically supports lower short-dated yields and a softer USD, while persistent tightness can push yields higher, strengthen the USD, and increase volatility across rate-sensitive assets.
Inflation: PPI and CPI

Key Dates:
- PPI: 14 January, 8:30 AM (ET)/ 15 January, 12:30 AM (AEDT)
- CPI (December 2025 data): 15 January, 8:30 AM (ET)/ 16 January, 12:30 AM (AEDT)
The inflation signal can be read as a pipeline from producer prices to consumer inflation. Markets are watching whether producer-level cost pressures continue to fade or begin to re-emerge.
What markets look for:
Core PPI, particularly services-linked components, provides an early indication of cost momentum. Core CPI breadth may help determine whether inflation is continuing to cool or showing signs of persistence.
A softer pipeline would reinforce confidence that disinflation can extend into early 2026, increasing the scope for a potential March policy adjustment. Stickier CPI readings above 3% would raise questions about the durability of recent progress.
How rates and the USD often react
Market reaction tends to be led by yields. Cooling inflation pressure usually pulls short-dated yields lower and softens the USD, while persistent inflation risks can push yields higher and tighten financial conditions.
Policy: January FOMC meeting

By the time the Federal Reserve meets at the end of January, markets will have processed the early growth, labour, and inflation signals of the year.
Key Dates:
- FOMC rate decision: 29 January, 2:00 PM (ET)/ 30 January, 6:00 AM (AEDT)
What markets look for:
A policy change is unlikely this month, but how those signals are framed in the statement and press conference still matters. With January cut expectations priced well below 20%, attention is on whether expectations for a March move, currently around 50%, begin to shift.
Confidence that inflation and labour pressures are easing would typically support lower yields and a softer USD. A more cautious tone could lift yields, strengthen the USD, and tighten global financial conditions.
Putting it all together
January’s data acts as condition-setters rather than decision points. The practical takeaway lies in how markets respond as those conditions become clearer:
If growth and labour soften while inflation continues to ease, markets may lean toward a more constructive risk backdrop, with Treasury yields remaining the key guide and expectations for policy easing later in Q1 firming.
If growth holds up and inflation proves sticky, a more cautious posture may be warranted, with heightened sensitivity to Treasury yields, USD strength, and pressure on equity valuations and rate-sensitive commodities.
