With U.S. inflation pressures easing somewhat, the burden of further interest rate hikes by the Federal Reserve (Fed) appears to be taking a step back. Since renewable energy industries such as solar and wind power require large-scale upfront investment, they are highly sensitive to interest rates. As a result, the direction of U.S. monetary policy is emerging as a new variable for related domestic stocks.

Mixed Stock Price Movements by Company

On the morning of the 14th, renewable energy-related stocks moved in divergent directions during trading hours. Starting with notable gainers, CNPlus rose 170 won (6.18%) from the previous trading day to 2,920 won, with its intraday high matching its current price. G2 Power traded at 10,800 won, up 370 won (3.55%), recording an intraday high of 10,960 won and trading volume exceeding 2.55 million shares.

G&Eco Systems also moved up 2.86% to 6,110 won, while SY rose 1.98% to 2,005 won. Among solar-related stocks, SDN gained 1.26% to 562 won and Gridwiz climbed 1.82% to 16,260 won. Jusung Engineering also recorded a 1.28% increase to 181,600 won, Abaco rose 1.67% to 11,570 won, and Nano Material and Unitest gained 1.18% and 1.23%, respectively.

On the other hand, declining stocks were also numerous. Hanwha Solutions dropped 2.19% to 35,750 won, and HD Hyundai Energy Solutions also traded down 1.37% at 122,500 won. OCI Holdings fell 2.34%, OCI declined 0.99%, and LS ELECTRIC dropped 3.50%, showing significant differentiation within the related stock group.

U.S. Interest Rate Variable in Market Focus

The key variable the market is focusing on is the U.S. interest rate. The U.S. July Producer Price Index (PPI) showed no change from the previous month, and the year-over-year increase slowed to 4.7%, down from 5.5% in June. As recent inflation indicators have been more stable than expected, concerns that the Fed would immediately proceed with additional rate hikes ahead of the September Federal Open Market Committee (FOMC) meeting have weakened compared to before.

However, it is premature to interpret the current situation directly as a 'rate cut phase.' The Fed's policy rate currently stands in the 3.50–3.75% range, and Richmond Fed President Thomas Barkin stated that whether further hikes are needed to bring inflation back to target levels remains an open question. The market also views the likelihood of a September pause as relatively high, though it has not completely ruled out the possibility of additional hikes later this year.

Why Renewable Energy Is Sensitive to Interest Rates

Solar and wind power businesses typically follow a structure in which large-scale capital is invested upfront for power plant construction, followed by cost recovery over a long period. For projects with a high proportion of borrowing, rising interest rates mean that both interest expenses and the overall cost of capital for the project increase. The Bank of England has also analyzed that renewable energy businesses have a high proportion of upfront capital and financing costs, meaning that monetary tightening and rising long-term rates could push up project costs.

Conversely, if upward pressure on interest rates eases, it could create a favorable environment by reducing the financing cost burden for renewable energy operators.

Investment Perspective: Focus on Easing 'Additional Tightening Risk' Rather Than 'Rate Cut Expectations'

The core of the current interest rate perspective on domestic renewable energy stocks lies not in the expectation that 'the U.S. will soon cut rates,' but in whether the risk of additional U.S. tightening is diminishing. If high rates persist longer or additional hikes become a reality, the financing costs for solar and wind projects could once again face increasing pressure. On the other hand, if inflation continues to stabilize and the Fed maintains a pause stance, there is a possibility of gradual changes in the financial environment of the renewable energy industry, which has been weighed down by prolonged high interest rates.

This is an interpretation based on current indicators, and the actual policy direction may vary depending on future inflation and employment data. Today's movement in related stocks should also be examined alongside individual company earnings, order intake, policy changes, and grid investments, rather than being explained solely by U.S. interest rates.

However, given the nature of the renewable energy industry, in which massive amounts of capital are invested over long periods, the direction of U.S. interest rates is expected to remain one of the key macroeconomic variables that will determine investment sentiment in related stocks during the second half of the year.
