아미노믹스 내부: BTS의 경제적 효과는 얼마나 지속될까?

S. Korea hits record Q1 foreign arrivals, up 23% on-year amid BTS boost

When the first chords echoed across Gwanghwamun Square and a sea of purple light sticks pulsed in unison, thousands of fans in attendance and millions more watching online across the globe roared their affection at BTS’ highly anticipated comeback concert last Saturday

To the casual observer, it was a spectacular display of pop culture dominance. To economists, the gathering at Gwanghwamun was a live demonstration of a macroeconomic powerhouse, as fans packed hotels, flooded local restaurants, pouring millions of dollars into the local economy in a matter of days.

As South Korea continues to aggressively leverage its cultural exports, the sheer scale of "Army-nomics" — driven by BTS’ fiercely loyal global fanbase — has prompted questions in financial circles.

The massively popular musical act records trillions of won in annual revenue, putting it on par with some of South Korea's major conglomerates. Hyundai Research Institute in 2018 estimated that BTS is expected to generate 5.56 billion won ($3.69 billion) in the Korean economy, which was nearly 0.3 percent of the country's gross domestic product that year.

Analysts now ask whether this unprecedented fandom economy represents a structural shift in global commerce or a cultural bubble waiting to burst.

Comeback economics

The financial footprint of a BTS concert extends far beyond ticket sales. According to research published by Brandeis University scholar Pinjie Lyu, the economic ripples of a major BTS event in Seoul are staggering. Looking back at the group's 2019 "Love Yourself: Speak Yourself" finale as a baseline, the direct economic impact of a Seoul concert hovers around 330.7 billion won.

However, when factoring in the indirect impacts — such as tourism surges, peripheral merchandise, and local business partnerships — the total economic value generated over a five-year window approaches a massive 922.9 billion won for a single concert series.

The Korea Culture and Tourism Institute estimated the upcoming 34-city tour will yield 1.2 trillion won per show. The Guardian reported that economists anticipate the North American leg alone will generate tens of trillions of won, significantly exceeding Taylor Swift's 60-date North American tour, which generated about $4.6 billion.

During Saturday’s concert, some local vendors reported a surge in sales of bibimbap and ramyeon, although no official figure exists yet for the exact influx of foreign capital regarding the performance. It was reported, however, that 18.4 million viewers watched the concert via Netflix that day, a testament to the global popularity of BTS.

Bubble or long-lasting future?

Questions remain over whether the financial impact of the group can last long term. The primary concern among financial analysts is what corporate finance calls "key-man risk" — an extreme reliance on a few individuals.

The data shows that much of the success enjoyed by BTS’ agency Hybe, the most valuable entertainment company by market capitalization, lies in the seven-person group.

According to NH Investment & Securities data, BTS generated about 880 billion won in sales in 2021 alone. This accounted for about 70 percent of their agency HYBE’s total revenue. In 2020, that proportion was even higher, reaching nearly 92 percent.

This heavy concentration is what triggers "bubble" warnings among traditional investors. An economy or corporate valuation deeply reliant on seven individuals is inherently vulnerable to disruption.

The South Korean market witnessed this volatility firsthand when uncertainties surrounding the members' mandatory military service caused massive fluctuations in entertainment stocks, only stabilizing once clear timelines were established.

Furthermore, as Lyu's paper points out, the group's integration into South Korea's state-sponsored diplomacy — such as their roles as presidential envoys — could inadvertently limit their commercial freedom.

“The heavy burden of diplomatic duties and the pressure to maintain a spotless political stance could eventually constrain their development as independent artists, potentially cooling the very organic global appeal that built their empire,” the paper said.

Still, some argue that the BTS model is fundamentally different from a speculative bubble. They say its foundation lies in long-term fan relationships.

Research on fandom behavior shows that parasocial bonds — formed through constant digital interaction — translate into durable engagement not just with the artists, but with Korea itself.

Fans often evolve into repeat visitors, consumers of Korean media, extending the economic lifecycle far beyond any single release or tour.

"The more BTS fans regard BTS as close friends, they feel more familiar with and close to Korea," explained Kim Su-jin, a communication professor at Ewha Womans University.

To measure this phenomenon, Kim and her research team conducted an in-depth survey of 195 American BTS fans, analyzing their social media usage and participation to understand how their relationship with the band directly improved their perception of Korea.

"BTS uses social media to interact with fans around, forging a semi-social relationship that creates a long-term bond," Kim said.

"This helps improve Korea’s image in the world. Our study confirmed that BTS fandom can be a key resource in Korea’s diplomatic activities. It has been academically proven that the central and local government’s leveraging of BTS and other K-pop stars can produce good publicity results."

Sustainable legacy

It is this semi-social bond that cements BTS' economic and cultural legacy, resisting traditional economic "bubble" models. A speculative financial bubble pops and leaves nothing behind, but the fandom economy is driven by community building and cultural integration, experts explain.

According to this theory, the fans who arrive for the music often stay for the culture, learn the Korean language, purchase modernized hanbok after seeing the members wear them on global broadcasts, and consume Korean media long after the stage lights go down.

The mechanism behind this impact differs from traditional industries. Rather than supply chains or capital investment, BTS’ economic engine is driven by what some researchers describe as “emotional infrastructure.”

In this theory, the fans are not simply consumers; they are participants in a shared identity, willing to spend across multiple categories, including concerts, travel, food, fashion, and language learning. This creates unusually resilient and price-insensitive demand

"They are paying a premium to participate in a shared cultural identity. That makes the demand highly inelastic compared to typical consumer goods," said Kim Sun-young, economy professor at Hongik University.

"The real test, then, is not whether BTS generates economic impact but whether that impact can be institutionalized," Kim explained.

"Can South Korea convert 'purple ripple effects' into a diversified cultural economy? Or does too much still depend on the continued momentum of one group? The challenge for South Korea now is how to ensure the cultural infrastructure BTS built can sustain the economy long after other generations of K-pop music."
