SEOUL, March 24 (AJP) —The choice of former Bank for International Settlements (BIS) economist Shin Hyun-song as the new central bank chief reflects a “firefighting” role against the Gulf War-driven perfect storm South Korea faces, and according to a former BIS colleague, he is best suited for the job.
How far and how fast the Bank of Korea governor nominee will translate his hawkish academic stance into policy is now the market’s central question, as Shin is set to take the helm amid growing inflationary pressure from the Gulf war fallout.
President Lee Jae Myung on Sunday has tapped Shin, a former BIS head of research, as the next BOK governor.
Shin, according to Agustín Carstens - former general manager of the Bank for International Settlements (BIS) in Seoul to speak at the Asia-Pacific Financial Forum hosted by Aju Media Corp. on Wednesday - “has a mixture of characteristics that is very unique.”
He "knows the Korean economy and financial system very well, and is an expert in macroeconomics and finance, including the connections between Korea and the rest of the world", Carstens said, adding that makes him the ideal monetary chief to “assess the shocks that the world and financial system is experiencing and to assess how it would affect the Korean economy very well.”
Given his academic track record, Shin is widely viewed as more responsive to shocks than incumbent Rhee Chang-yong, whose policy stance has often been seen as cautious.
Critics, including Democratic Party lawmaker An Do-geol, argue that the BOK’s passive signaling under Rhee contributed to a surge in household lending.
“With the won hovering near 1,500 and 10-year yields pushing above 3.8 percent, the president appears to have seen a ‘firefighter’ in Shin,” an anonymous finance ministry official said.
Markets have already begun pricing in a more hawkish turn. The three-year bond yield spiked to above 3.6 percent and the 10-year yield climbed to 3.8 percent upon the announcement, sharply above the 2.50 percent base rate.
Shin’s reputation as a policy hawk dates back to his early work during the global financial crisis. In a Federal Reserve Bank of New York paper, he warned that loose monetary policy fuels balance sheet expansion and asset bubbles, underscoring the need for preemptive tightening.
He reinforced that stance in a 2022 interview, arguing that “it is better to overreact with rate hikes than to be timid” when tackling inflation.
His framework extends beyond rate policy. In a 2012 NBER paper, Shin highlighted “non-core liabilities” such as certificates of deposit and financial bonds as key sources of systemic risk, calling for tighter monitoring during credit booms.
At the BIS, he has also emphasized policy calibration. In a March 16 briefing on a potential Strait of Hormuz disruption, he suggested central banks may “look through” temporary supply shocks rather than react mechanically with rate hikes.
This places Shin at the center of a clear policy tension: a hawk in principle, but pragmatic in execution.
His communication philosophy also signals a shift.
In a 2017 BIS speech titled “Can central banks talk too much?”, Shin warned that excessive signaling risks trapping policymakers in an “echo chamber,” diminishing the effectiveness of forward guidance.
This contrasts with Rhee’s tenure, which featured frequent communication on structural factors such as demographics, supply chains and social dynamics.
Despite these nuances, few dispute that Shin will respond proactively to inflation risks.
“We expect Shin to favor tightening once excess liquidity and easing financial conditions become evident,” said Kim Jin-wook of Citi, who forecasts two 25-basis-point hikes this year.
KB Securities’ Lim Jae-kyun did not fully agree, saying that if the Gulf-driven shock proves temporary and inflation expectations remain anchored near 3 percent, the BOK may refrain from immediate tightening.
Beyond traditional monetary policy, the BOK under Shin's watch is expected to accelerate digital agenda.
Carstens, described him as a "world-leading expert" in the impact of technological change, including tokenization and artificial Intelligence and was confident Shin would bring "a lot of dynamics, or continue the dynamics, of what the Bank of Korea has started to do in terms of digitizing the financial system and the role of the central bank.”
