Welcome to Thoughts on the Market. I’m Kathleen Oh, Morgan Stanley’s Chief Korea and Taiwan Economist. Today I’ll revisit Korea's demographic emergency and how the recent pension reform is trying to address it.

It's Thursday, May 1st, at 4pm in Hong Kong.

Some of you may remember that I came on the show last fall to talk about the crisis-level demographic challenges in Korea. Korea officially became a super-aged society at the end of 2024. This means that more than 20 per cent of the population is 65 or older.

In the face of its rapidly aging population and a fertility rate that has hit rock bottom, Korea is taking decisive action finally. The national assembly recently passed a landmark pension reform bill to amend the National Pension Act. This measure marks the first major change to its pension system in 18 years. And it’s supposed to improve the pension fund's financial sustainability to prepare for a rapidly aging population that will only accelerate from here.

The amendments include raising pension contribution rates and adjusting the income replacement ratio to 43 per cent. These changes aim to delay the depletion of the fund to 2064 to 2071, in an upside scenario. Without this reform, the fund would have been depleted by 2055, just 30 years later.

This reform avoids having to sell the fund's financial assets by delaying depletion. It also assures pension-holders of the stability of future pension assets. And, last but not least, it increases the pension fund's capacity for financial investments, which could lead to higher returns.

This is the first step towards making legislative, and therefore more structural changes to respond to the reality of a super-aged society. Moreover, it kicks off a sweeping reform agenda that includes the pension program, labor market, education system, and capital markets.

It’s also notable because the center-left Democratic Party of Korea and the conservative People Power Party were able to show bipartisan support and a public consensus to reach a deal, especially during the recent tumultuous political events that took place in Korea.

That said, the reform also has some potentially negative economic impacts. Higher pension contributions could squeeze households' disposable income, putting mild but additional downward pressure on aggregate consumption and savings. Especially considering that as people age, they tend to consume less – and this can lead to a structural slowdown in private consumption.

Despite Korea's challenges with an aging population, we're cautiously optimistic about its future – especially because [of] the recent rebound in the country's fertility rate. After marking a drop every year since 2015, it rebounded to 0.75 in 2024. While still far below the ideal replacement ratio of 2.1, this rebound is a small but certainly a positive sign.

Looking ahead, Korea's working population is expected to decrease by 50 per cent in the next 40 years unless the country ensures a dramatic rebound in the fertility rate to 1.0 or higher by 2030. In the meantime, we expect further adjustments to the pension reform bill, we expect further discussions around lifting of retirement age, along with the labor market reform next in line on the economic front. The Korean government will continue to execute on its demographic policy agenda.
