About the Swedish Krona (SEK)
The Swedish Krona is the official currency of Sweden, Sweden's currency since 1873. Its ISO 4217 code is SEK and it uses the symbol kr. The SEK is managed by the Riksbank, the world's oldest central bank, established in 1668.
Sweden maintained the Riksbank's overnight rate below zero from 2015 to 2022, one of the longest experiments with negative interest rates globally. The SEK is influenced by risk sentiment given Sweden's open, export-oriented economy.

SEK History and Background
The Swedish Krona (SEK) was Sweden's currency since 1873. the Riksbank, the world's oldest central bank, established in 1668, the institution responsible for monetary policy in Sweden, has maintained the SEK's role as legal tender through successive economic cycles, adjusting interest rates and reserve requirements to manage inflation and support growth. The SEK is one of the world's actively traded currencies, participating in the global forex market that the Bank for International Settlements (BIS) 2022 Triennial Survey measured at $7.5 trillion in average daily turnover.
Central bank policy decisions are the most direct tool the Riksbank, the world's oldest central bank, established in 1668 uses to influence the SEK's exchange rate. Interest rate announcements, inflation reports (particularly consumer price index data), and GDP growth figures from Sweden are the primary data releases watched by currency traders. When the Riksbank, the world's oldest central bank, established in 1668 raises rates above comparable economies, the SEK tends to attract capital seeking higher yield, and vice versa when rates fall.
SEK Denominations
The Swedish Krona is subdivided into 100 smaller units (2 decimal places). the Riksbank, the world's oldest central bank, established in 1668 issues the SEK in a range of note denominations for everyday and large-value transactions, plus coins for smaller amounts.
Physical SEK banknotes and coins serve as legal tender within Sweden. For international transactions and cross-border transfers, electronic exchange is available around the clock through forex markets, banks, and specialist services like Wise, OFX, and Revolut.
When traveling to Sweden, the best exchange rates are typically obtained by using a no-fee debit card at a local ATM rather than airport currency exchange counters, which often charge premiums of 5–8% above the mid-market reference rate.
Is the SEK Pegged to the Dollar?
The Swedish Krona is a freely floating currency. Its exchange rate is determined by market supply and demand in global foreign exchange markets. the Riksbank, the world's oldest central bank, established in 1668 influences the rate indirectly through monetary policy decisions, primarily interest rate settings, rather than by fixing or pegging the rate to another currency. Some central banks do intervene occasionally to limit extreme volatility, but the SEK rate is not administratively set.
SEK Economic Context and Global Role
As one of the world's major traded currencies, SEK participates in the global foreign exchange market, which the Bank for International Settlements (BIS) 2022 Triennial Survey measured at $7.5 trillion in average daily turnover. The SEK is quoted against most major world currencies around the clock from Sunday evening (New Zealand open) through Friday afternoon (New York close), with peak liquidity during the London trading session (08:00–17:00 GMT), which accounts for roughly 38% of total global forex volume.
SEK Exchange Rate Factors
the Riksbank, the world's oldest central bank, established in 1668 decisions are the single most powerful near-term driver of the SEK exchange rate, but four structural forces shape the currency's value over time.
Monetary Policy. the Riksbank, the world's oldest central bank, established in 1668 sets interest rates to manage inflation and support economic growth. When Sweden raises interest rates relative to other countries, the SEK tends to strengthen as investors seek higher returns. Rate cuts or expectations of easing typically weaken the currency. Markets price in expected rate changes months in advance, so central bank communication and meeting minutes can move the SEK significantly even before any actual rate change.
Inflation and Purchasing Power. A country with higher inflation than its trading partners sees its real exchange rate erode over time, even if the nominal rate is stable. the Riksbank, the world's oldest central bank, established in 1668's primary mandate typically includes maintaining price stability, usually targeting annual inflation in the 2–3% range depending on the jurisdiction. When inflation significantly exceeds this target, the currency tends to weaken as the market anticipates either rate hikes or erosion of purchasing power.
Trade and Current Account Balance. Sweden's trade with the world creates supply and demand for the SEK. Exporters sell foreign currency to repatriate revenue, supporting the SEK. Importers buy foreign currency to pay overseas suppliers, which weakens it. A structural current account surplus, more exports than imports, generally supports a currency over time, while a deficit puts pressure on it.
Risk Sentiment and Capital Flows. As an internationally traded currency, the SEK is subject to global capital flows. During periods of global uncertainty, investors may move capital toward perceived safe-haven currencies (primarily USD, CHF, and JPY), which can weigh on higher-yielding or commodity-linked currencies.
SEK Volatility and Risk Profile
Currency volatility measures how much an exchange rate fluctuates over a given period. Annualized volatility, the standard deviation of daily log returns multiplied by the square root of 252 trading days, is the standard metric used by options traders and risk managers.
Major currencies like the SEK typically exhibit moderate volatility of 5–15% annualized under normal market conditions. Volatility spikes during major data releases (GDP, CPI, employment reports), central bank policy announcements, and geopolitical events. The SEK's volatility can be tracked in the 30-day statistics table at the top of each pair page on LiveRates.io.
For travelers, short-term volatility means the exchange rate you see today may differ meaningfully from the rate available next week. For businesses with ongoing cross-border transactions, currency risk management tools such as forward contracts or options can hedge against adverse SEK movements.
Sending Money to or from Sweden
For international transfers involving SEK, the choice of provider significantly affects the final amount received. The rate shown on LiveRates.io is the mid-market reference rate, the interbank benchmark before any provider markup. Here is a comparison of typical costs:
| Provider Type | Typical Rate Margin | Transfer Fee |
|---|---|---|
| High street bank | 2–4% above mid-market | $10–$40 fixed |
| Airport / hotel exchange | 5–15% above mid-market | Usually none |
| Specialist service (Wise, OFX) | 0.3–1.5% above mid-market | Small fixed or percentage fee |
| Debit card abroad (ATM withdrawal) | 0–2% (network rate) | ATM fee may apply |
For transfers above $1,000, using a specialist service rather than a traditional bank typically saves $20–$80 per transaction. Transfers above $10,000 may qualify for preferential rates through dedicated FX brokers.
Key tip: Compare the total cost including the exchange rate margin and any fixed fees, not just the headline rate. A service advertising zero fees may embed a larger spread in its exchange rate.
