The 5-year, 5-year forward inflation rate (5y5y) measures expected inflation for the five years starting five years from now. Central banks watch it as a sign of whether long-term inflation expectations stay anchored.

Why it matters:

• If 5y5y rises significantly, markets may doubt the central bank's commitment to its target.
• That can lead to more hawkish policy expectations and affect the currency.
• Stable 5y5y readings suggest short-term inflation spikes are seen as temporary.

Where to find it:

• Derived from inflation swaps or from TIPS breakeven rates.
• Some public data sources (e.g. FRED) publish a daily series.

For intraday traders, 5y5y is background context rather than a trading signal. It helps judge whether a CPI surprise is likely to change the central bank's stance.

Do you follow long-term inflation expectations, or only actual inflation data?

I treat 5y5y as a weekly check rather than something I watch intraday. When it drifts more than 20 basis points in a month, I take CPI surprises more seriously as a potential policy story instead of a one day noise print.

Stable readings do the opposite. A hot CPI with a flat 5y5y usually fades faster in EURUSD than the same print when long term expectations are already climbing.

The FRED series is what I use, and I compare it against the move in the front end of the rate curve rather than against spot alone. That pairing tells me whether the market is pricing a lasting shift or just a temporary spike.

One edge case: after a large fiscal announcement the swap can jump while traders still treat the currency move as short lived. I have been wrong on that twice this year by fading too early.

Do you keep a simple threshold for how far 5y5y can move before you change how you size USD trades into data? For me it is still mostly qualitative, and I am not sure that is enough.
