The global market for language services is robust, with the Korean interpretation sub-segment driven by strong economic and cultural ties. The total addressable market (TAM) for language services is estimated at $64.7 billion in 2023, with a projected 5-year compound annual growth rate (CAGR) of est. 4.5%. While demand for Korean interpretation remains strong in legal, medical, and corporate sectors, the single greatest threat to the in-person delivery model is the rapid adoption of high-quality Remote Simultaneous Interpretation (RSI) platforms, which offer significant cost and logistical advantages. Procurement strategy must evolve to a hybrid model, leveraging technology for efficiency while reserving in-person services for high-stakes engagements.
The specific market for in-person Korean interpretation is a niche within the broader language services industry. The global TAM for all language services is the most reliable proxy for scale and growth. Key geographic markets for Korean interpretation demand are the United States, South Korea, and China, driven by trade, M&A activity, and legal proceedings. Growth is steady, fueled by the globalization of Korean businesses (e.g., Samsung, Hyundai, LG) and the global influence of its cultural exports.

| 2023 | $64.7 Billion | est. 4.5% |
| 2024 | est. $67.6 Billion | est. 4.5% |
| 2025 | est. $70.7 Billion | est. 4.5% |

The market is highly fragmented, with a few large-scale players and thousands of smaller agencies and independent contractors.

The price build-up for in-person interpretation is based on a unit of time, typically a half-day (4 hours) or full-day (8 hours) rate, often with a 2-hour minimum for short assignments. The final cost is an aggregate of the base interpreter rate plus all associated expenses. The base rate is determined by the mode of interpretation (consecutive is cheaper; simultaneous is more expensive and may require a team of two), the interpreter's level of certification (court-certified > medically qualified > general), and the technicality of the subject matter.
Travel and Expenses (T&E) are passed through to the client and represent the most variable component of the total cost. Last-minute bookings (less than 48-hour notice) frequently incur a premium of 50-100% on the base rate.
Most Volatile Cost Elements: 1. Airfare & Lodging (T&E): est. +15% YoY [Source - BCD Travel, Jan 2024] 2. Specialized Talent Premiums (e.g., Simultaneous Patent Law): est. +10-20% YoY due to scarcity. 3. Last-Minute Service Surcharges: Can add +50-100% to the base rate.

Demand for Korean interpretation in North Carolina is projected to grow above the national average, driven by significant foreign direct investment in the automotive/EV battery and advanced manufacturing sectors. Recent announcements from Korean-affiliated entities in the state create a concentrated need for technical, business, and legal interpretation services, particularly around the Piedmont Triad and Research Triangle Park. Local supply of highly-qualified interpreters, especially for simultaneous or technical assignments, is limited. This supply/demand imbalance creates a risk of price premiums and limited availability for urgent requests, making a proactive supplier qualification strategy essential.
| Risk Category | Grade | Justification |
|---|---|---|
| Supply Risk | Medium | General business interpreters are available, but certified/technical/simultaneous talent is scarce and concentrated in major hubs. |
| Price Volatility | Medium | Base rates are stable, but T&E and last-minute premiums create significant total cost volatility. |
| ESG Scrutiny | Low | Primary exposure relates to fair labor practices for freelance interpreters, which is managed through supplier vetting. |
| Geopolitical Risk | Low | Service delivery is largely insulated from direct geopolitical events on the Korean peninsula. |
| Technology Obsolescence | High | The in-person model is directly challenged by mature and cost-effective RSI and VRI technologies. |
