# USDT 溢價

貨幣兌換商如何賺錢，以及 USDT 價格為何因國家而異。

## 傳統的貨幣兌換商如何賺錢

貨幣兌換商不需要匯率發生波動。他們只需以稍低的價格買入某種貨幣，再以稍高的價格賣出。

|          | 需求        | 與貨幣兌換商的交易                                 |
| -------- | --------- | ----------------------------------------- |
| **客戶 A** | 需要新幣（SGD） | 貨幣兌換商以 **1 USD = 1.340 SGD** 的價格從 A 處買入美金 |
| **客戶 B** | 需要美金（USD） | 貨幣兌換商以 **1 USD = 1.360 SGD** 的價格向 B 處賣出美金 |

兩個價格之間的差額，即**價差**，就是貨幣兌換商的利潤。

## 同一種幣，不同的價格

雖然 USDT 與美元 1:1 掛鈎，但這只是理論價格。實際上，USDT 在不同國家往往會出現不同的交易價格。這種價格差異稱為 **USDT 溢價（USDT Premium）**，也是 MoonExe 流動性服務持續產生需求的重要因素。

| 國家         | 溢價成因                        | 一般溢價範圍       |
| ---------- | --------------------------- | ------------ |
| 🇦🇷 阿根廷   | 惡性通貨膨脹，比索持續貶值               | 高峰期可達 10–20% |
| 🇳🇬 尼日利亞  | 本幣持續貶值，美元供應短缺               | 高峰期 +5–15%   |
| 🇪🇬 埃及    | 外匯管制及黑市美元剛需                 | +5–12%       |
| 🇹🇷 土耳其   | 里拉匯率波動劇烈，對抗通脹需求             | +3–8%        |
| 🇵🇰 巴基斯坦  | 美元短缺，海外匯款需求                 | +2–6%        |
| 🇻🇳 越南    | 加密貨幣需求旺盛，銀行體系兌換渠道有限         | +1–3%        |
| 🇮🇩 印度尼西亞 | 進出口貿易結算需求驅動                 | +0.5–2%      |
| 🇹🇭 泰國    | 跨境貿易與跨境匯款需求旺盛               | +0.5–1.5%    |
| 🇪🇺 歐元區   | 幾乎不存在明顯溢價：外匯市場流動性充足，可自由兌換外幣 | 0–1%         |

{% hint style="info" %}
**貨幣流通存在摩擦，穩定幣需求就隨之而生。** 目前全球約有 1,400 億美元的 USDT 正在流通，但其分布並不均衡。MoonExe 正是連接這些流動性缺口的橋梁。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hub.moonexe.com/home/zh-tw/yun-zuo-fang-shi/usdt-yi-jia.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
