[Inside Chodong] The K-dot Plot and the Central Bank Governor's Message

The More the Market Focuses on "Headlines Only,"
the Greater the Need for Clarity

This week, a divergence in perspectives regarding forward guidance (conditional interest rate outlook) between the new heads (nominees) of the monetary authorities of South Korea and the United States became evident. More precisely, the difference emerged in their manner of expressing their views on forward guidance. Kevin Warsh, nominee for Chair of the U.S. Federal Reserve, stated during his confirmation hearing on April 21 (local time), "I do not think we should signal our future decisions," and drew a line by saying, "I do not trust forward guidance."

In contrast, Shin Hyun-song, Governor of the Bank of Korea, expressed a positive nuance toward Korea-style forward guidance in his inaugural address on the same day (Korean time), saying, "Korea is drawing attention not only for K-culture but also for the 'K-dot plot' and other areas." In an earlier confirmation hearing, he also mentioned that a period is needed to check and assess the operation of the K-dot plot, stating, "For the time being, I will maintain the current system." He did not reveal his personal convictions about the system.

The K-dot plot is a tool that allows one to check the 'future base rate' as envisioned by the Bank of Korea's Monetary Policy Board members. The seven board members independently indicate their expectations for the interest rate level six months ahead, under the current circumstances, by each placing three dots according to probability. Through the distribution of 21 dots, the future interest rate outlook can be intuitively understood. The Bank of Korea stated that it introduced the K-dot plot to more clearly present the baseline outlook and upside/downside risks, thereby strengthening communication with the market and enhancing predictability. Since its introduction in February, it has generally been evaluated as helping to stabilize market expectations.

However, the system's weakness is that, if the forecast path is changed to reflect conditional changes in circumstances, it could actually create confusion in the market. On this issue, former Governor Lee Chang-yong assessed that, "Whether this system can take root depends on how much the market accepts that the interest rate outlook is 'conditional on the current situation.'"

Based on past remarks and actions, Governor Shin is likely to believe that it is more effective for the central bank to deliver straightforward and clear messages rather than presenting a variety of conditional possibilities through tools like the K-dot plot. He has previously stated thatbecause the market is not an individual who makes rational decisions, it pays attention only to 'the big headline' and does not read the 'small print.' He also noted that a central bank might end up interpreting as market signals the very signals it originally created and disseminated to the market. When asked for his view on this, Governor Shin replied cautiously, "Communication with the market is not one-way; it means that the central bank also interprets market prices, and there is interaction."

The second K-dot plot will be released on May 28, together with Governor Shin's first base rate decision and economic outlook announcement after his inauguration. Since the start of the Middle East war following the first K-dot plot release in February, it has become increasingly difficult to gauge the direction of inflation, financial stability, and economic recovery. With an upward revision of the inflation outlook already anticipated, market interest in the K-dot plot, which will now reflect the new governor's view, is higher than ever. Above all, attention is focused on the tone Governor Shin will take at the press conference, especially since he previously pledged to "uphold the Bank of Korea's core mandate of price (stability)."

Given that the decision has been made to maintain the system for now, Governor Shin must deliver a clear message about the distribution presented in the K-dot plot during the press conference. While I agree with his view that "it is not appropriate to always respond with the same tools and methods," denying a 'hawkish' (preference for monetary tightening) stance, it should be remembered that such comments could easily be perceived as ambiguous statements or evasive answers that conceal his convictions. If that happens, it could actually cause confusion in communication with the market.
