The Australian dollar has depreciated over 35% against the US dollar in the past decade, facing triple pressures from dollar dominance, weak commodity demand, and diminishing domestic economic attractiveness. The future trend depends on the RBA interest rate policy, China's economy, and the US dollar performance. In the short term, a recovery rebound is expected, but attention should be paid to global economic uncertainties and the possibility that a strong US dollar may limit upside potential. Investors need to remain flexible in responding to market changes.

Elon Musk's proposed space AI data center project has sparked market enthusiasm for the solar energy industry, with Yuanjing's stock price rising over 40% in just five days.

An often-overlooked cost truth: Why precise calculation of stock profits matters
When investing in stocks, many people focus only on price fluctuations and overlook a hidden monster that directly eats into profits—transaction fees. Many investors believe that when stock prices go up, they can profit, but they haven't actually calculated the costs clearly. Taking Taiwanese investors as an example, when buying a stock, they pay a commission fee; when selling, they must pay another commission fee plus transaction tax. These layered costs can ultimately lead to a situation where the account shows gains but in reality incurs losses.
To truly achieve accurate stock profit calculations, you first need to understand all the cost items involved in the trading process. From broker commissions, transaction taxes, to various miscellaneous fees, each one directly impacts the final investment return. That’s why savvy investors must thoroughly understand these costs before accurately determining their profit thresholds.

In the international financial markets, headlines like "The US Dollar Index has risen" appear frequently, but they often leave investors confused. What exactly does the US Dollar Index reflect? Why do its fluctuations influence gold, US stocks, and even Taiwan stocks? Today, we will take a deep dive into this core indicator that global investors are paying close attention to.
What exactly is the US Dollar Index? A simple analogy makes it clear
The US Dollar Index (abbreviated as USDX or DXY) is a "relative index" that measures the strength of the dollar against other currencies, not an absolute value.
Imagine this: when you look at the stock market, you pay attention to the S&P 500 or the Dow Jones Industrial Average to understand the overall market performance. The logic of the US Dollar Index is exactly the same — it tracks not stocks, but the exchange rate changes of the dollar against six major currencies.
These six currencies are: Euro (EUR), Japanese Yen (JPY), British Pound (GBP), Canadian Dollar (CAD), Swedish Krona (SEK)

The US dollar enters an interest rate cut cycle, affecting global capital flows. The key factors are interest rate policies, money supply, trade deficits, and trust in the US dollar. The future outlook for the US dollar is expected to be volatile at high levels before weakening, impacting gold, stocks, and Crypto. Market uncertainties also create trading opportunities, and investors are advised to seize every signal of turning points.

Taiwan dollar to Japanese yen reaches 4.85! Is now a good time to enter?
By the end of 2025, the Japanese yen has once again become a focus for Taiwanese investors and travel enthusiasts. From the beginning of the year at 4.46 to the current 4.85, an accumulated increase of 8.7%. Behind this comparison of the yen exchange rate lies a reorganization of the global economic landscape. Are you ready to hop on this train?
Top 3 reasons why the yen is worth investing in
1. Rigid demand for travel and consumption
Tokyo, Osaka, Hokkaido, Okinawa — Japan remains Taiwan’s top travel destination. Local cash transactions account for as much as 40%, especially in drugstores, convenience stores, and small merchants that mostly accept only cash. Purchasing agents, Japanese online shopping, studying abroad, working holidays, and other demands also drive individuals to continue buying yen.
2. One of the three major safe-haven currencies
The yen, US dollar, and Swiss franc are listed as global safe-haven assets. Japan’s economy is stable, with a low debt ratio, and market turbulence often leads to increased demand for the yen.

In 2025, under the push for global net-zero carbon emissions targets, the hydrogen energy industry is experiencing an unprecedented wave of investment. As a core solution for clean energy, hydrogen fuel cell technology is gradually moving from concept to commercial application. For investors, the key is to identify the true industry leaders—companies that not only possess advanced technology but also have a complete industrial chain layout and government support.
Why has the hydrogen energy industry become a hot investment spot?
The global hydrogen energy market size has reached $1.1 billion (2023), and is expected to reach $30.6 billion by 2030, with a compound annual growth rate of 61.1%. According to the International Energy Agency's forecast, to achieve the net-zero carbon emissions goal by 2050, global hydrogen demand needs to reach 530 million tons. This means that hydrogen energy is not only an investment concept but also an inevitable choice for the future energy structure.
In Taiwan's 2050 net-zero carbon emissions pathway plan, the hydrogen supply ratio is set at 9%.

Have you ever wondered why the US stock market suddenly halts trading during significant declines? The logic behind this is actually quite simple—when people fall into collective panic, rationality is often overwhelmed by emotion. The circuit breaker mechanism in the US stock market is designed to hit the pause button during such moments, giving investors a chance to breathe and think.
When does the market trigger an "emergency stop"?
The operation logic of the US stock market circuit breaker (Circuit Breaker) is straightforward: when the S&P 500 index drops by a certain percentage compared to the previous trading day's closing price, trading will be paused. Specifically, there are three trigger levels:
First line of defense (Level 1 Circuit Breaker): When the decline reaches 7%, all stock trading is paused for 15 minutes. However, if this decline occurs near the end of the trading day (after 15:25), trading will continue.
Second line of defense (Level 2 Circuit Breaker): If within the same trading day the index drops another 13%, then

The article discusses the recent rebound of the Chinese stock market and its future investment potential, highlighting factors such as policy support, corporate earnings growth, and AI applications driving the market. Although institutional forecasts suggest room for upward movement in A-shares, potential risks still exist, as the gains are mainly driven by valuation expansion rather than fundamental improvements. For Taiwanese investors, it is important to choose brokers carefully and pay attention to risk management.

Although the British pound has recently experienced a slight rebound, it faces severe challenges, and many investment banks hold a cautious outlook on its prospects. The lack of fundamental support and ongoing fiscal vulnerabilities keep market sentiment weak. While the central bank's interest rate cuts may stimulate the economy, if growth prospects do not improve, the pound's rally is unlikely to last.

The core of trend trading lies in following market trends and seeking profits, rather than aiming for the lowest buy-in and highest sell-out. Its advantage is that it does not require precise judgment of market extremes, but the challenge is to confirm the trend and avoid false signals. Successful trend trading relies on careful observation and discipline, as well as flexible use of technical indicators for entry and exit decisions. By patiently waiting and following market signals, traders can achieve steady profits amid volatility.

As of October 2025, international gold prices have surpassed $4,300 per ounce, setting a new historical high. In a global economic environment facing uncertainty and increased stock market volatility, more and more investors are turning their attention to the gold market. This article will delve into the core logic of gold investment, the advantages and disadvantages of various investment tools, and practical operational suggestions.
Why has gold become an essential investment?
Preservation of Purchasing Power: Against Hidden Inflation
The economic phenomena of the past five years tell us a harsh truth: price increases far outpace wage growth. After the outbreak of the pandemic in 2020, global central banks issued大量货币刺激经济, and inflation expectations soared. Gold performed remarkably during this period — rising from $1,500 at the beginning of 2020 to nearly $4,000 in 2025, with a cumulative increase of over 160%.
The logic behind this is simple: gold is a tangible asset, and its purchasing power resistance far exceeds that of paper

December 10, 2025, the exchange rate of New Taiwan Dollar to Japanese Yen reached 4.85, with travel to Japan and Yen investment demand continuing to rise. But do you really know how to exchange Yen in the most cost-effective way? Today, we will explain four currency exchange methods to you all at once, helping you save unnecessary expenses.
Why is the Yen worth exchanging? Three main reasons
Many people think exchanging Yen is just for traveling to Japan, but in fact, the value of Yen goes far beyond your imagination.
Travel and daily necessities
Although Japan has a credit card penetration rate of 60%, most small shops, attractions, and public transportation still only accept cash. Whether it's shopping in Ginza, Osaka Dotonbori cuisine, skiing in Hokkaido, or vacationing in Okinawa, cash is essential. Additionally, many purchasing groups, Japanese online shopping enthusiasts, and even international students need to pay directly in Yen, and students need to plan their currency exchange in advance to avoid sudden fluctuations.
Global safe-haven currency status
The Yen is ranked alongside the US Dollar and Swiss Franc as one of the three major safe-haven currencies.

Taiwan dollar depreciation, Japanese yen appreciation, leading to a surge in people exchanging for yen by the end of 2025. But do you know? Exchanging 50,000 TWD through the wrong channel could cost you an extra 2,000 TWD—equivalent to a month's worth of coffee money.
Today, we won't beat around the bush. We'll directly calculate with actual rates: at banks, online apps, foreign currency ATMs, airport reservations—what's the most cost-effective, and when should you act.
Four ways to exchange new yen bills, with significant cost differences
Method ①: Bank counter exchange of new bills (the most traditional but the most expensive)
Bring cash TWD directly to the bank or airport counter to exchange for new yen bills on the spot. It sounds safest, but in reality, it's the most costly option.
The key issue is the "cash selling exchange rate." Banks do not offer the best rates from the international market; instead, they add a markup based on the cost of cash settlement—usually 1-2% above the spot rate. For example, according to Taiwan Bank's rate on December 10, 2025, the cash selling rate is approximately 0

The wave of NT dollar depreciation continues, with the Japanese yen exchange rate rising from 4.46 at the beginning of the year to 4.85 in December 2025, an accumulated appreciation of 8.7%. Many people are asking: Is it really cost-effective to exchange yen now? The answer is yes, but the premise is that you choose the right currency exchange method. Just selecting different channels can result in cost differences of over 1,000 yuan, enough to cover a month of bubble tea.
Is it cost-effective to exchange yen now? Timing analysis
In the second half of 2025, Taiwan's currency exchange demand increased by 25%, mainly driven by three factors: tourism recovery, hedging strategies, and arbitrage opportunities.
Looking at the exchange rate trend, the yen, as one of the world's three major safe-haven currencies (alongside the US dollar and Swiss franc), has inherent value preservation properties. The Bank of Japan Governor Ueda Kazuo recently made hawkish comments, pushing up the rate hike expectation to 80%, with a projected 0.25 percentage point increase to 0.75% at the December 19 meeting (a 30-year high). Japanese bond yields have already reached 1
