Money hits different when you’re talking about billions. Even if it's Korean Won. Most people see a number like 1.7 billion and their brain goes straight to "lottery winner" or "tech CEO salary." But when you’re converting 1.7 billion won to usd, the reality is a bit more grounded than a private island, though it's still a massive chunk of change.
Right now, $1.7 \text{ billion KRW}$ is roughly $1.22 \text{ million}$.
Why roughly? Because the exchange rate is a jittery beast. It moves while you’re drinking your coffee. If the Bank of Korea decides to hike rates or if the US Federal Reserve gets hawkish, that 1.22 million could slide down to 1.15 or jump up toward 1.3 in a matter of weeks. Currency markets don't care about your budget plans.
The Exchange Rate Rollercoaster
Converting 1.7 billion won to usd isn't just about a math formula. It’s about timing. Back in the early 2020s, the won was stronger. You might have seen closer to $1.4 \text{ million}$ for that same 1.7 billion won. Today, things are tighter.
The USD/KRW pair is one of the most watched in Asia. South Korea is an export powerhouse. Samsung, Hyundai, SK Hynix—these giants live and die by how the won stacks up against the dollar. When the dollar is strong, Korean exports are cheaper for Americans to buy, which sounds great for business, but it makes everything imported into Korea—like oil and food—way more expensive.
Why the "Billion" Label is Tricky
In Korea, the term is ship-chil-eok. "Eok" is the unit for 100 million. So 17 eok equals 1.7 billion. It sounds like a staggering, world-ending amount of money to an English speaker because we associate "billion" with "Billionaire."

But in Seoul?
1.7 billion won is the price of a decent, three-bedroom apartment in a "good but not elite" neighborhood like Mapo or parts of Songpa. It’s not even enough for a high-end unit in Gangnam anymore. In Gangnam, you're often looking at 3 billion won just to get in the door. It's wild. You’re a "billionaire" on paper, but you’re basically just a homeowner with a nice view of the Han River and a hefty property tax bill.
Real World Purchasing Power: US vs. Korea
If you take that 1.7 billion won to usd conversion—roughly $1.22 \text{ million}$—and try to spend it in the United States, your mileage varies wildly depending on the zip code.
In San Francisco or Manhattan? That’s a 600-square-foot condo with a questionable elevator.
In Houston or Atlanta? That’s a mini-mansion with a pool, a three-car garage, and enough left over to buy a Porsche 911.
The purchasing power parity (PPP) between these two countries has shifted. Honestly, Korea used to feel cheap. Not anymore. If you're standing in a convenience store in Seoul, a kimbap roll is still a bargain, but try going out for a high-end "Omakase" dinner in Hannam-dong. You’ll be burning through that 1.7 billion won faster than you think.
The Hidden Costs of Moving Big Money
You can't just Venmo $1.2 \text{ million}$ across the ocean. Banks will eat you alive on the spread. If the mid-market rate says your 1.7 billion won to usd is worth $1,220,000$, a traditional bank might only give you $1,190,000$.

They take a 1% to 3% cut in the "spread"—the difference between the buy and sell price.
On $1.7 \text{ billion won}$, a 2% spread is 34 million won.
That’s $24,000$ gone.
Just for the privilege of moving your own money.
Taxes, Laws, and the "Kimchi Premium"
We have to talk about the Foreign Exchange Transactions Act. Korea has strict rules. If you’re a resident and you want to send more than $100,000$ USD out of the country in a year, you have to provide documentation to the bank. They want to know where the money came from. Was it an inheritance? Real estate sale? Crypto gains?
Speaking of crypto, the "Kimchi Premium" often messes with people's heads when calculating 1.7 billion won to usd. Sometimes, Bitcoin trades at a higher price in Korea than in the US. People think they can just buy BTC in the US, sell it in Korea, and pocket a 5% profit.
It's called arbitrage. It’s also incredibly hard to do legally because of those capital controls. If you manage to sell 1.7 billion won worth of BTC, getting that money back into USD involves a mountain of paperwork and potential tax liabilities from the National Tax Service (NTS).
The Reality of Investment
If you had $1.22 \text{ million}$ (the result of our 1.7 billion won to usd swap) sitting in a high-yield savings account in the US right now, you’d be pulling in maybe $50,000$ to $60,000$ a year in interest.
In Korea? Interest rates have historically been lower, though they’ve chased the US Fed recently.
Many Koreans prefer "Jeonse"—a unique rental system where you give the landlord a massive lump sum (often 1.7 billion won would cover a very high-end Jeonse) instead of monthly rent. You get the money back when you move out. It’s basically an interest-free loan to the landlord.

People see the "1.7" and think they are wealthy.
Wealth is relative.
If you’re moving from Seoul to a mid-sized US city with $1.2 \text{ million}$, you’re wealthy.
If you’re moving from a US tech hub to Seoul with that same amount, you’re just "comfortable."
The South Korean Won is a "proxy currency" for global risk. When the world is scared—think war, inflation, or tech crashes—investors run to the US Dollar. They sell the Won. This means your 1.7 billion won suddenly buys fewer dollars. If you are planning a major transaction, like buying a house or funding a business, you have to watch the 10-year Treasury yields in the US. They drive the dollar's strength.
Practical Steps for Large Conversions
Don't use a standard retail bank for 1.7 billion won. Just don't. You are flushing money down the toilet.
- Look into specialized FX firms. Companies that handle high-net-worth transfers can usually give you a spread of 0.5% or less.
- Tranche your transfers. Don't move all 1.7 billion won at once. The market is volatile. Move 400 million won this week, 400 million next week. This averages out your exchange rate—a strategy called Dollar Cost Averaging, but for currency.
- Check the tax treaty. The US and South Korea have a tax treaty to prevent double taxation. If you sold a property in Korea for 1.7 billion won and are moving it to the US, make sure you have your "Tax Clearance Certificate" from the Korean tax office. Without it, the bank won't let the money leave the country.
- Account for the "Reporting" requirement. If you are a US person (citizen or green card holder), and you have 1.7 billion won in a Korean bank account, you MUST file an FBAR (Report of Foreign Bank and Financial Accounts). The penalty for forgetting is catastrophic. We’re talking $10,000$ per violation or more.
The Bottom Line on 1.7 Billion Won
Converting 1.7 billion won to usd puts you right around the $1.2 \text{ million}$ mark. It’s the kind of money that changes a life, but it doesn’t end the need for a job in a major city. It buys a home, or a top-tier education, or a very solid retirement nest egg in a low-cost-of-living area.
Watch the exchange rates, get your tax papers in order, and never accept the first rate a bank teller offers you. For an amount this large, the "preferred rate" is something you have to demand.
To make the most of this capital, consult with a dual-country tax specialist who understands both the IRS and the Korean NTS. Ensure your FBAR and FATCA filings are up to date before moving the funds to avoid triggering an audit. If you're looking to invest, compare the yield of US Treasuries against Korean government bonds (KTBs), as the current spread significantly impacts your long-term purchasing power in either currency.
