If you've ever flown into London, opened your mobile banking app, and felt a wave of disbelief at the exchange rate displayed on the screen—don't worry, you're not alone in feeling this way.

The exchange rate of 1 British pound once again surpassing 1 US dollar feels as jarring as seeing a meme coin with eight decimal places. The US has a much larger economy, and the dollar is the "lifeline" of the global financial system, with nearly half of the world's goods priced in US dollars. So why does 1 unit of British pounds still hold more "value" than 1 unit of US dollars?

The first point that needs to be clarified is exactly what cryptocurrency practitioners are repeatedly taught to focus on—the unit price.

In the field of cryptography, monetary units are important because the unit is tied to the supply, which in turn is related to market capitalization. Market capitalization is precisely the metric people use to roughly assess the size of an asset class. A token with a price of $1 and a supply of 100 billion is perceived very differently from a token with a price of $1 and a supply of only 100 million, because the total value behind these two "$1" prices differs vastly.

But the logic of fiat currency is not the same. You might still use a similar intuition to understand it, but you must identify the correct focal point—the currency pair.

Currency pairs are the core underlying assets.

GBP/USD is the most fundamental currency pair in trading, and the "1" preceding the British pound is essentially a design choice in the interface, similar to how cryptocurrency exchanges decide whether to use "satoshis" (sats) or "Bitcoin" (BTC) as the unit of quotation.

The reality in mid-January 2026 is that 1 British pound can be exchanged for approximately 1.34 U.S. dollars (with slight fluctuations up or down). The exchange rate has remained largely stable within this range over the past six months, averaging around 1.34, and it has never approached the parity line of "1:1"—this data can be verified using a GBP/USD exchange rate tracking tool.

This number merely represents "the price of one currency measured in another," it is not a "scoreboard" of national strength, nor is it a "certificate" of purchasing power.

Rather than reflecting the "balance of power between the UK and the US," it is closer to the logic of cryptocurrency trading pairs like Ethereum/BTC (ETH/BTC).

So, why does the price in British pounds always look "higher"?

Because the monetary unit is arbitrary, and history does not reset the "counter."

People often can't help but view 1 pound and 1 dollar as comparable units of currency within the same supply system, but this is not the case. The pound is a currency unit with a longer history, and its modern form is the result of long-term historical evolution. Its unit scale is essentially "inherited." No country regularly recalibrates its currency unit to achieve global alignment of currency units.

Of course, countries can change the scale of their currency units through "redenomination"—by adjusting decimal places, changing banknote designs, or introducing a "new currency." The public will see a completely new set of numbers, but this does not mean the economy suddenly becomes wealthier.

This also explains why the "very low value of one yen" does not indicate a weak Japanese economy—it only means that the yen's monetary unit is inherently small.

Therefore, the question of "why the dollar should now surpass the pound" essentially presumes a premise: "countries with larger economic sizes will ultimately have currencies with higher unit value." However, in reality, there is no such "finish line"; only fluctuating exchange rates exist.

Using an analogy from the field of cryptography: suppose two blockchains have different definitions for their "base unit"—one chain directly refers to its smallest unit as "1," while the other defines 1,000 of its smallest units as "1." If you only look at the unit price on the screen, you might mistakenly think the latter has a "higher value," but in reality, the difference lies only in the placement of the decimal point.

The core of the "dollar hegemony" lies in its function as the global financial "infrastructure," rather than necessarily achieving a numerical goal such as "1 dollar being worth more than 1 pound."

When people talk about the "strength of the dollar," what they are really referring to is the central role the U.S. dollar plays in the global system: foreign exchange reserves, transaction settlements, trade pricing, collateral, debt instruments, and trade financing—these seemingly mundane functions are in fact the cornerstone of the global financial system.

This hegemony is clearly reflected in the IMF's COFER (Currency Composition of Official Foreign Exchange Reserves) data, which tracks the composition of foreign exchange reserves held by central banks around the world, with the U.S. dollar consistently holding the largest share.

The core of this hegemony lies in "use cases" and "network effects." Even if the spot exchange rate shows that 1 pound is still higher than 1 dollar, this hegemony remains valid—because exchange rates only represent the relative prices of the two currency units.

Global influence does not enforce specific integer relationships between currency units.

So, what exactly drives the fluctuations in the British pound to U.S. dollar exchange rate?

This is precisely where intuition in the cryptocurrency field comes into play—crypto practitioners have long accepted the logic that "price is a product of capital flows." The difference lies in the fact that what drives fiat currency exchange rates are capital flows at the macroeconomic level.

The exchange rate fluctuations between the British pound and the U.S. dollar stem from some very routine and very human factors: yield-seeking capital, risk-averse capital, and funds used to pay everyday bills.

If explained in a more narrative way, we can view the British pound and the US dollar as "two large buckets filled with promises," and the role of the foreign exchange market is to determine the relative value of these two "buckets of promises" at the current moment.

Specifically, the main driving factors include the following four categories:

Currencies behave similarly to "interest-bearing assets," because holding a currency often means holding the country's short-term interest rate instruments, or at least being affected by the interest rate trends of that country.

Currently, the interest rate narratives of the UK and the US have not shown a明显的 obvious one-sided tilt.

The Bank of England cut its benchmark interest rate to 3.75% at its monetary policy meeting ending on December 17, 2025 — this information can be found in the Bank of England's official summary of rates.

The Federal Reserve, in its Federal Open Market Committee (FOMC) statement on December 10, 2025, lowered the target range for the federal funds rate to 3.50%-3.75%.

When the short-term interest rates of both countries are in roughly the same range, it is difficult to form a clear rationale that "interest rate differentials alone could push the GBP/USD exchange rate below 1:1."

In the long run, inflation erodes the value of money, and exchange rates reflect investors' judgments: whose currency can better preserve purchasing power? And which economy is more likely to "compromise" under inflationary pressure (such as by cutting interest rates prematurely)?

In December 2025, the UK inflation rate rose to 3.4%, prompting the market to immediately begin discussing "whether this will slow down the Bank of England's future interest rate cuts." This data can be reviewed in the inflation special report, or you can learn about the data release schedule through the Office for National Statistics (ONS) Inflation Data Hub.

Single-month data cannot determine the direction of currency movements, but the market will continuously adjust its expectations for the future based on new data, with inflation being a key variable in this process.

When global markets fall into panic, the U.S. dollar often becomes a "safe-haven asset" and is heavily bought up. This is not a "praise" of American politics or social stability, but rather an instinctive reaction formed through the functioning of the global financial system.

If you've observed the scenario where "Bitcoin's price falls when U.S. dollar liquidity tightens," you would understand this logic — people rush to hold assets that "can most quickly complete bill payments and collateral settlements."

This flight-to-safety behavior can strengthen the U.S. dollar, and it doesn't at all depend on "a dollar being worth more than a pound"—because the scale of the currency units themselves isn't the core issue.

The UK and the US differ in their "balance of payments structures," and the types of investors attracted to their assets are also different, and these capital flows directly affect exchange rates. At the same time, the global role of the dollar means that the US must supply dollars to the world through trade deficits and capital markets. There is a complex interaction between this "supply" and the global "demand" for dollars.

Frankly, this part of the logic is indeed confusing—and your intuition is right; the market itself is complex.

The "purchasing power" people refer to is not the spot foreign exchange rate.

If you're asking, "Okay, but what can I actually buy with these currencies?" then you're actually concerned with another concept: purchasing power parity (PPP). This concept suggests that the true value of different currencies should be compared based on the local prices of "the same basket of goods."

The Organization for Economic Cooperation and Development (OECD) provides a clear and practical definition of purchasing power parity (PPP): PPP is the "exchange rate conversion factor that eliminates differences in price levels across countries and equalizes purchasing power." This concept also represents the core logic underlying PPP datasets.

Purchasing power parity explains why "even when exchange rates indicate a currency is 'strong,' tourists may still feel poor in some countries and wealthy in others." Spot exchange rates represent the "market price" of a currency, while purchasing power parity is a tool that "converts currency into its everyday purchasing power."

For a more intuitive understanding, you can refer to the "Big Mac Index"—the existence of this index is not accidental. It is a popularized tool for measuring purchasing power parity, enabling ordinary people to easily grasp the core concept.

If we use the logic of the encryption field to correspond:

· Spot foreign exchange rate = The "trading price" of cryptocurrency

Purchasing Power Parity = the "real value after deducting local costs" in the crypto space, similar to how people use "real rate of return" instead of "nominal rate of return" to measure asset value.

Neither is an "absolute truth"; they simply answer different questions.

So, in what situations can 1 dollar "exceed" 1 pound?

This is a vision for the future and also where the true power of mental models in the crypto space can truly come into play.

Crypto professionals have long been accustomed to "analyzing probabilities within contextual scenarios"—because every cryptocurrency price chart tells a probabilistic story about technological adoption, liquidity, regulatory policies, market narratives, and risk. The analysis of exchange rates against fiat currencies can also follow this logic.

The British pound to U.S. dollar exchange rate falling to 1:1 or below (i.e., "parity") essentially represents a "fundamental shift in market mechanisms or trends." This scenario is not impossible—historically, other currency pairs have experienced similar movements multiple times. It simply requires "a set of persistent forces pushing in the same direction for a sufficiently long time."

Here are three easy-to-understand core scenarios:

If the UK's economic growth remains weak and inflation declines, the Bank of England may adopt an "aggressive rate-cutting" policy. Markets will adjust in line with these expectations, and "lower expected returns" could drag down the value of the British pound.

However, this scenario comes with constraints: the UK's inflation problem has not yet been fully resolved (the CPI rose to 3.4% in December 2025), making the narrative of "short-term rapid interest rate cuts" difficult to justify in the near term. (For related CPI data and discussions on interest rate expectations, please also refer to the current inflation special report.)

To achieve a GBP/USD exchange rate below 1:1 through this path, it may require a combination of two factors: "British interest rates remaining significantly lower than U.S. interest rates over the long term," and "economic growth differentials that lead investors to continuously favor U.S. dollar assets."

Sometimes, currency fluctuations are not caused by "benign differences," but rather because investors suddenly demand higher compensation for risk in order to hold assets from a particular country.

If the UK faces a "fiscal credibility crisis" (such as questions about the sustainability of its debt), political instability, external financing shocks, or another situation where "government bond volatility becomes a market focus," the British pound's exchange rate could experience a rapid reassessment.

This is similar to a "liquidity crisis" in the crypto space — commonly referred to by crypto professionals as a "waterfall decline."

If this risk premium remains persistently high, the likelihood of the pound reaching parity against the dollar will significantly increase—because a "sustained risk premium" is precisely the force that can alter long-term exchange rate levels.

If global markets enter a "long-term risk-off mode" and demand for U.S. dollar financing rises, the dollar may be "continuously bought," and the duration of this trend could last longer than most people expect.

This scenario is not unfamiliar to crypto traders: at this point, all assets tend to move in the same direction, leveraged funds are forced to liquidate, and "assets that can be used to fulfill debt obligations" will become the market's focal point.

In such an environment, the pound may still weaken even if the UK "has done nothing wrong"—and the "parity of the pound against the dollar" could merely be a "side effect" of increased global demand for the U.S. dollar.

None of the above scenarios require that "America becomes stronger"—they only require that "the market is willing to pay a higher relative price for the dollar than for the pound."

Understand this: "Power" relates to politics, systems, and scale; whereas "price" relates to capital flows and market expectations.

Key Takeaways for Readers in the Cryptocurrency Space

If you can only remember one sentence, remember this:

"The British pound is 'more valuable' than the U.S. dollar at the unit level"—this is essentially an illusion caused by the way currency units are defined; the actual market price of the currency pair is the core factor that truly deserves attention.

A more persuasive way to understand this is to view the British pound and the US dollar as "two blockchains"—they compete in terms of "credibility, policy, incentive mechanisms, and trust," and the exchange rate is the "real-time chart" reflecting the outcome of this competition.

When people argue whether the "dollar unit should surpass the pound," they are essentially trying to impose an "order" on the world, as clear-cut as a market capitalization ranking table for cryptocurrencies. However, money does not owe us this kind of "order."

They are "historical products wrapped in modern macroeconomics," and exchange rate charts are precisely where history and reality intersect.

If you want to understand "why the purchasing power of 1 pound still exceeds that of 1 dollar," stop fixating on the numerical values of the currency units, and instead focus on the forces that determine exchange rates: interest rates, inflation, risk, and the silent question that financial markets ask every day—where should capital be placed in the future?
