The Bank of Korea (BOK) will deliver its first interest rate hike in more than three years on Thursday (July 16), formally joining the tightening ranks of major global central banks. Under the triple pressure of persistently above-target inflation, robust economic growth, and a sharply weaker South Korean won, the policy path leaves little suspense. However, the market’s real focus has shifted from “whether to hike” to “the subsequent pace of tightening” — will it be a steady march or a rapid-fire assault?
According to a survey of 37 economists conducted from July 7 to 13, a striking 36 respondents expect the BOK to raise its benchmark interest rate by a quarter percentage point (0.25 percentage points) from the current 2.50% to 2.75% at this meeting. This would mark the first time the bank has restarted a rate-hiking cycle since 2023.
Barclays economist Bum Ki Son analyzed the situation: “At the last meeting, the BOK simultaneously raised both its economic growth and inflation forecasts, which already sent a relatively clear signal. The governor explicitly stated that, in rare circumstances, the central bank’s various mandates are not in conflict but rather point in the same direction of rate hikes.”
Triple Pressure from Inflation, the Won, and Economic Growth
Behind this rate hike decision lie warning signals from multiple macroeconomic indicators. The June Consumer Price Index (CPI) accelerated to a 3.2% year-over-year increase, hitting a two-and-a-half-year high and marking the fourth consecutive month above the central bank’s 2% target. Markets expect inflation to average around 3% in the second half of the year, remaining far from policymakers’ comfort zone.
Price pressures stem mainly from two sources. On the supply side, high global oil prices fueled by the rekindled U.S.-Iran war continue to stoke energy costs. On the demand side, first-quarter economic growth recorded its fastest pace in nearly six years, with strong domestic demand and exports providing fertile ground for price increases. BOK Governor Rhee Chang-yong has previously stated clearly that, against the current backdrop of high oil prices, inflation is expected to exceed the central bank’s target for a considerable period, making it necessary to raise interest rates.
The softening South Korean won represents another headache for policymakers. The won has depreciated more than 4% against the U.S. dollar this year, directly driving up the cost of imported energy and raw materials while intensifying imported inflation pressures. Another survey indicates markets expect the won to weaken by a further 1% or more by the end of July.
BofA Global Research Korea economist Benson Wu noted: “We expect won depreciation to be a core focus. Although policymakers have intensified verbal intervention and coordinated messaging across ministries in recent weeks, the impact on the won appears relatively limited.” He added that markets will closely watch for any signals that could open the door to consecutive rate hikes, though this is not BofA’s base-case scenario.
Hawkish Outlook: Rates Seen at 3% by Year-End
Regarding the subsequent rate path, most economists forecast the BOK will adopt gradual tightening. Among 31 respondents, 28 expect one more rate hike by the end of the fourth quarter, pushing the policy rate to 3.00%. The median forecast further shows the BOK will raise the key rate to 3.25% in the first quarter of 2027 and hold it at least through the end of next year — 25 basis points higher than the forecast in the May survey.
The central bank’s dot plot released in May also revealed a similar hawkish signal, with a majority of board members at that time expecting the policy rate to reach 3% within the next six months.
Behind this hawkish stance lie expectations of strong economic growth and above-target inflation. The survey median shows inflation averaging 2.7% this year and 2.2% next year, while gross domestic product (GDP) is projected to grow 2.8% in 2026 and 2.1% in 2027.
The Pace Debate: Steady March or Rapid-Fire Assault?
Although a rate hike is a foregone conclusion, intense debate persists in the market regarding the BOK’s tightening pace. The base-case scenario envisions a July hike followed by another adjustment in October. However, multiple domestic and international investment banks and analysts have recently begun floating the possibility of “consecutive rate hikes,” primarily outlining two accelerated paths.
The first is “consecutive hikes in July and August.” Market sources indicate that if the BOK’s assessment of core inflation proves more hawkish than expected, the October hike could be brought forward to August. Even if falling oil and petroleum product prices ease supply-side pressures, demand-side pressures driven by the semiconductor export boom and improving domestic demand may prove more worrisome. Analysts believe the central bank could raise rates twice in quick succession, then use a period of at least three months to observe the impact on the real economy and financial markets.
The structural improvement in the semiconductor industry is an important basis for this view. Some research institutions estimate that, benefiting from the strong performance of the IT sector and export growth, South Korea’s GDP gap turned positive in the first quarter of this year. Current account surpluses and a strengthening stock market have driven increased market liquidity, while indicators such as housing prices and exchange rates also suggest financial conditions remain accommodative. One market participant stated: “High exchange rates, upward growth revisions, and persistently high prices may prompt the BOK to hike consecutively in August to demonstrate clear policy resolve.”
Another more aggressive forecast is the “consecutive fourth-quarter hikes” scenario, where the BOK pauses in August before raising rates in both October and November. Barclays assesses that the BOK may not directly hint at consecutive July-August hikes at this meeting, but the risk of back-to-back hikes could be deferred to the fourth quarter. Key variables will be the upcoming second- and third-quarter economic growth figures and core inflation data, as well as the government’s annual budget proposal due at the end of August. If economic performance continues to exceed expectations and core inflation shows no signs of easing, the central bank may conclude that its policy response has fallen behind economic conditions.
Furthermore, if the government drafts an expansionary budget due to increased tax revenues from the semiconductor boom, this would further stimulate domestic demand and prices, reinforcing the necessity for consecutive fourth-quarter hikes. ING even assesses that South Korea’s current policy rate is roughly 100 basis points too low relative to economic conditions, and even accounting for the gap between the benchmark rate and actual lending rates, there remains approximately 80 basis points of additional tightening room.
Nevertheless, the steady-march view remains mainstream. Some analysts point out that a simple upward revision in economic growth rates is insufficient to justify overly rapid tightening; the ultimate key lies in whether the semiconductor boom can effectively transmit to a substantive rise in domestic demand and core inflation. The expectation is that the BOK will hike in July, adopt a “hawkish hold” in August to observe more data, and then make its next adjustment in October.
South Korea’s Pace Amid a Global Tightening Wave
The BOK’s pivot is not an isolated event. Across the Asia-Pacific region, the central banks of Australia, New Zealand, Indonesia, and the Philippines have all previously tightened monetary policy. South Korea had remained on hold until now, finally catching up with global central banks at a moment when inflation, growth, and exchange rates are rarely aligned in pointing toward tightening. As Thursday’s decision approaches, markets will focus not only on the rate figure itself but will also scour Governor Rhee Chang-yong’s post-meeting remarks for any clues about the future tightening path and its speed.
