“When you know the flow of money and have the right values ​​about money,
“Money is on my side.”

The Ministry of Education has created a new subject called 'Finance and Economic Life' in the 2025 curriculum.
The goal is to strengthen financial capacity by fostering the financial knowledge and sound financial decision-making skills necessary for young people.


Young people live in a rapidly changing digital financial environment.
They actively use second-hand trading sites such as 'Carrot' and are interested in stocks in the entertainment industry such as SM and HYBE.
They also wonder how to save up their allowance to make more money, and what to look out for when looking for a part-time job.
Meanwhile, illegal gambling targeting youths by using the internet and smartphones as their main communication method and illegal social media loan sharking called "proxy deposit" are making headlines.


How can young people preparing for financial independence lead safe and rational financial lives? Author Kim Na-young, a middle school social studies teacher, has filled young people with vivid financial knowledge in "Money Challenge Starting Today!" to answer their questions.
From practical information like a checklist to avoid second-hand trading scams, how to manage your credit score, and things to watch out for when starting your first part-time job, to basic concepts that will help you understand economic news, such as interest rates, exchange rates, bonds, and diversified investments, it explains them in an easy and fun way.
It is full of valuable knowledge that young people need to know to grow into healthy economic players.

It's a good idea to set a 'maximum amount you want to spend this week or month' for each item.
“I decide that I won’t spend more than 3,000 won on webtoons every week.”
What if you set a limit of 10,000 won per month for in-game items, but today you spend 9,900 won? You won't have any more money to spend on games this month.
At this time, you should not use money that has been divided into other items.
To successfully control your spending using a psychological account, you must keep track of the amount for each item.
If you write it down every time you use it, you can check how much you used for each item, right?

Late fees, called late fees in proxy deposits, are usually around 2,000 won per hour, but they seem like small amounts, so it's easy to overlook the risks.
However, if you convert it to an annual interest rate, it means that you are paying interest of over 1,000%.
(…) When A borrowed money, the agent depositor asked for his student ID, phone number, and home address.
He threatened to use this to visit my house a week later, spread my personal information on the internet, and sue me for fraud.
Such acts constitute illegal debt collection prohibited by current law.
In times like these, you shouldn't try to solve it yourself.
Ask your parents, teachers, or school police officer for help, or call the Financial Supervisory Service's reporting center at 1332 for advice.

Who do you think has a higher credit score: A, with an annual salary of 100 million won and a history of frequent late payments, or B, with an annual salary of 30 million won and a history of never being late? Surprisingly, B's credit score may be higher.
This is because if A has a lot of income but does not know how to spend it systematically and has a lot of experience with late payments, he is considered an untrustworthy person.
(…) Here’s why you should start taking an interest in credit management from the time you’re in school.
It makes a big difference whether you live your life consciously knowing that keeping promises to others is ultimately for your own good or not.

Warren Buffett, a famous investment expert, and his mentor Benjamin Graham are people who made a lot of money by analyzing companies, purchasing stocks of companies they judged to be good at low prices, and waiting for them to rise.
Warren Buffett especially said, “Buy stocks of good companies at a reasonable price, and don’t invest in companies you don’t know.”
I have to remember two things: picking a good company in a field I'm interested in, and determining whether that company's stock is "at a good price" when I'm thinking of buying it.
When buying stocks, you look at the company's financial health, its growth potential, and how consistently it can generate profits.
We also examine whether the stock price is overvalued compared to this.
One more thing, look at what the company values, not just its profitability or growth potential.
I would also like to consider what impact the products or services my company produces will have on the world.

What does higher US interest rates have to do with exchange rates? Capital, or money, flows across borders worldwide.
If the US raises its benchmark interest rate, deposit rates will also rise.
Let's say that if you deposit money in our country, you get 3% interest per year, but if you deposit money in the US, you get 5% interest per year.
So, you'd want to deposit money in the US, right? More people would buy dollars and deposit or invest in the US, which would increase demand for dollars and push up the exchange rate.
