Why does it feel unreal that the price of goods has dropped to the 2% range while the total cost of the shopping basket remains the same? The key point is not that prices have become cheaper, but that the speed at which prices are rising has slowed.
We will examine the implications of inflation settling in the 21TP-3T range as of August 2026, breaking it down into trends in interest rates, exchange rates, oil prices, and food prices. By also summarizing the reasons why official indicators differ from actual living costs, we can see at a glance what changes are expected in the future.
Prices have stabilized in the 2% range; does this mean prices have gone down?
An inflation rate of 2% does not mean that the price of goods itself has decreased by 2%. It means that while price levels may still be higher than a year ago, the rate of increase year-over-year has slowed to the 2% range.
For example, if a product that was 10,000 won last year is 10,280 won this year, the price has risen. However, if the year-over-year growth rate is 2.81 TP3T, it is interpreted that the rapid upward trend seen previously has slowed down.
The stabilization of prices in the 2% range is closer to 'stabilization of the speed of price increase' rather than 'price decline'.
You must understand this difference to properly connect interest rates with consumption. The feeling on households is different from a situation where prices drop significantly immediately compared to a situation where prices are stably managed.

What changes will occur to interest rates and the Korean Won?
When prices stabilize, the central bank has less need to raise interest rates to suppress demand. If signals of declining inflationary pressure persist, expectations for interest rate cuts grow, leading to a relaxation of loan interest costs and corporate financing burdens.
However, interest rates are not determined based solely on domestic prices. Since U.S. interest rates, international oil prices, exchange rates, and economic trends interact, it is not a structure where an interest rate cut is immediately confirmed based on prices alone.
When the value of the won strengthens, the burden of imported raw materials and energy prices is reduced, contributing to price stability. In fact, from July 1 to August 11, 2026, the value of the won rose by 9.41 TP3T against the dollar, and on August 14, the won-dollar exchange rate was 1,417.00 won.
A decline in the exchange rate is advantageous for lowering import prices, but it can pose a different burden on export companies. Therefore, even though it is a positive change for consumers, corporate earnings and stock market reactions vary by industry.
If international oil prices rise again, will the trend in the 21TP-3T range be shaken?
International oil prices are a key variable that simultaneously stimulates both consumer prices and perceived inflation. When gasoline and diesel prices rise, transportation costs increase, and this burden is subsequently reflected in the prices of food and daily necessities.
On August 14, 2026, Brent crude was $88.52 per barrel and WTI was $82.40. However, on August 17, Brent crude rose to $90.87 and WTI to $84.50, indicating that oil prices did not maintain a stable trend.
The government can curb excessive price hikes in the distribution process by implementing a price ceiling on petroleum products or inspecting gas stations. However, since these measures cannot eliminate the rise in international oil prices themselves, a prolonged surge in oil prices will once again place a burden on the trend of price stability.
Why do grocery prices still feel expensive?
The official Consumer Price Index and the Cost of Living Index differ in their aggregate subjects and weights. Since the Cost of Living Index is heavily influenced by frequently purchased items such as food and energy, the burden felt by consumers may be greater even if the overall Consumer Price Index is 2%.
Everyday items such as rice, vegetables, fruit, dining out, and transportation costs have a more direct impact on consumer perception than furniture or home appliances purchased once a month. If prices do not decrease but only the rate of increase slows, consumers will still face high price tags.
Prices of agricultural, livestock, and fishery products fluctuate significantly depending on shipment volume and weather conditions. While the government’s provision of 60 billion won in discount support for agricultural, livestock, and fishery products or the reduction of tariffs on imported fruits may alleviate the purchasing burden for certain items, the prices of all food ingredients will not drop by the same margin.
The Emergency Supply Stabilization Task Force and daily item-specific monitoring are mechanisms for rapidly identifying such fluctuations. They operate by monitoring changes in circulation volume and prices to prevent supply disruptions or price surges in specific items from spreading to overall prices.
What signal does price stability send to the stock market and consumption?
If prices stabilize, the likelihood of lower interest rate burdens increases, which can create a favorable environment for the stock market. Companies will have room to reduce interest costs, and households may gradually recover consumption as the burden of loan repayments eases.
On August 14, 2026, the KOSPI rose 2.421 points to 6,977.94 and climbed as high as 7,010.86 during the trading session. During the same period, expectations of slowing U.S. inflation and easing interest rate burdens stimulated investor sentiment, but semiconductor earnings and export trends also played a role in the rise.
From August 1 to 10, domestic semiconductor exports recorded $10 billion, an increase of 155.41 TP3T compared to the same period last year. The rise in the index should be viewed not as a result of price stability alone, but as a combined result of expectations for exports and corporate earnings.
The sentiment within the market was also inconsistent. On August 10, the KOSPI rose by 0.651 TP3T while the KOSDAQ surged by 6.971 TP3T, and at that time, foreign investors net sold approximately 1.4887 trillion won on the KOSPI. Subsequently, during the week of August 14, the direction of supply and demand shifted as they net bought approximately 6.55 trillion won in the securities market.
What indicators will households look at going forward?
To connect the stabilization of prices in the 21TP-3T range with the cost of living, you must not look solely at the total price figures. To gauge the actual burden, you must examine the prices of high-spending items—such as groceries, energy, dining out, and transportation—along with international oil prices and exchange rates.
U.S. economic trends also affect domestic interest rates and financial markets. In August 2026, U.S. retail sales in July fell 0.61 TP3T from the previous month, and the University of Michigan's preliminary consumer sentiment index fell 7.61 TP3T from the previous month to 51.0.
As such, even if inflation slows, economic concerns could intensify if consumption and sentiment weaken. Conversely, if oil prices rise again, the burden of both inflation and interest rates could increase simultaneously, making it difficult to assume that the trend of stability will continue in only one direction.
The most important point is not to accept the figure of 2% as a price reduction. When assessing the burden on your shopping basket, you must look at the prices of frequently purchased items, the direction of oil prices and exchange rates, and changes in interest rates together, rather than just the rate of increase.
