Forward Guidance
포워드 가이던스
A monetary policy communication tool through which a central bank signals its own forecasts and intentions regarding the future path of policy to the public and financial markets. Introduced alongside the spread of inflation targeting in the late 1990s, it became a core pillar of unconventional monetary policy after the 2008 financial crisis, when policy rates hit their effective lower bound. Forward guidance is divided into Delphic guidance (communicating the central bank's economic outlook) and Odyssean guidance (committing to a specific rate path). Most modern central banks now favor conditional, Delphic-style guidance to preserve policy flexibility.
In depth
Origins and Development
Forward guidance emerged alongside the spread of inflation targeting in the 1990s as part of a broader shift toward central bank transparency. Until 1994, the Federal Reserve did not even announce FOMC decisions immediately; markets had to infer policy changes indirectly from the size of open market operations. This 'secrecy' gave way gradually: immediate release of FOMC statements began in 1994, and the 'balance of risks' language was introduced in February 2000.
The Reserve Bank of New Zealand was the first to publish an official policy rate projection path in 1997, followed by Norges Bank (2007) and Sweden's Riksbank. The Fed introduced calendar-based guidance in August 2011 ('at least through mid-2013'), transitioning to state-contingent guidance in December 2012 with explicit unemployment and inflation thresholds. Since 2012, the Fed has also published the FOMC participants' rate projections quarterly as a dot plot.
Delphic vs. Odyssean
Campbell et al. (2012) established the distinction: Delphic guidance presents a forecast of the policy rate path based on the central bank's economic outlook without commitment, while Odyssean guidance publicly commits to a specific rate path. The Odyssean label draws on Homer's Odyssey, in which Odysseus has himself bound to the mast to resist the Sirens' call. The Fed's calendar-based guidance of the early 2010s approximated the Odyssean approach, but the post-pandemic inflation surge led most central banks to abandon unconditional promises in favor of flexible, state-contingent Delphic guidance.
Forward Guidance in Korea
In October 2022, the Bank of Korea began publishing Monetary Policy Board members' conditional three-month base rate outlook in quantitative form. The innovation was introduced during an aggressive tightening cycle to reduce market uncertainty and has since proven effective in anchoring market rate expectations and reducing short-term rate volatility. As of 2025, the BOK is pilot-testing a dot-plot format and extending the projection horizon to one year.
