What is forward guidance?

Forward guidance is a central bank's communication about the likely future path of policy rates, designed to shape market expectations and ease financial conditions today. It works through the expectations channel, moving expected short rates that propagate along the yield curve. The Fed, ECB, and Bank of England all deployed it heavily after 2008 to add stimulus once policy rates hit zero.

What is the difference between Odyssean and Delphic forward guidance?

Odyssean guidance binds the committee to a future rate path like a commitment device, while Delphic guidance merely forecasts where rates are likely to go. Odyssean guidance is more powerful because it sacrifices future flexibility for credibility today, but it is harder to sustain — markets test whether a committee will honor a promise that conflicts with incoming data.

What is the difference between calendar-based and state-based forward guidance?

Calendar-based guidance ties policy to a date (rates low "at least through mid-2015"), while state-based guidance ties it to economic outcomes such as inflation or unemployment thresholds. The FOMC used calendar guidance in 2011 then switched to state-based thresholds in December 2012, pegging near-zero rates to 6.5% unemployment and 2.5% projected inflation.

Why has forward guidance lost its power in 2025-26?

Forward guidance has lost its edge in the 2025-26 regime because policy rates are positive, the zero lower bound no longer binds, and supply-driven inflation makes paths hard to commit to. With data-dependence the watchword, markets discount explicit path commitments as noise and lean instead on the dot plot and incoming inflation and labor prints.

Did forward guidance cause the 2013 taper tantrum?

The 2013 taper tantrum exposed how fragile forward guidance is: a hint that the FOMC might slow asset purchases spiked the 10-year Treasury yield roughly 100bp in months, even though policy rates were unchanged. It showed that guidance about one tool (QE) can unanchor expectations about another (rates), and that exit communication is as consequential as the original commitment.

Glossary

forward guidance

policy guidance · rate-path guidance

Forward guidance is a central bank's communication about the likely future path of policy rates, used to shape market expectations and steer financial conditions today. It comes in calendar-based (date-contingent), state-based (outcome-contingent on inflation or unemployment thresholds), or qualitative open-ended forms.

How it works

By committing to a future rate path, a central bank moves expected short rates, which propagate through the yield curve to long-term rates and broader financial conditions via the expectations channel. Guidance is "Odyssean" when it binds the committee to a path, or "Delphic" when it merely forecasts. It was the workhorse easing tool once policy hit the zero lower bound and conventional cuts were exhausted.

Why it matters now

In the 2025-26 regime of positive policy rates and sticky, supply-driven inflation, forward guidance has lost its edge: with the ZLB no longer binding and data-dependence the watchword, markets discount explicit path commitments as noise, leaning on the dot plot and incoming prints instead.

Example

During the post-2008 recovery, the FOMC's December 2012 statement tied near-zero rates to thresholds of 6.5% unemployment and 2.5% projected inflation — state-based guidance designed to push out expected liftoff. The 2013 "taper tantrum" then showed how fragile guidance is: a hint of QE tapering spiked the 10-year Treasury yield roughly 100bp in months despite unchanged policy rates.
