The Japanese Yen: From Post-War Recovery to Global Power
How the Japanese yen went from a fixed post-war rate to a global carry-trade currency, and what it means for Iraqi importers of Japanese goods.
The Japanese yen10.06+0.28% (JPY) occupies a unique place among world currencies. It is the currency of an industrial and export powerhouse, and at the same time a central instrument in global financial markets through what is known as the “carry trade.” To understand the yen’s position today, it helps to trace its path from the ruins of post-World War II Japan, through the country’s economic miracle, into its “lost decades” of deflation and near-zero or negative interest rates, and finally to its current role in global trade — and what all of this means for importers of Japanese goods in Iraq and the Kurdistan Region.
The Yen After World War II: From Collapse to Reconstruction
Japan emerged from World War II with a shattered economy, destroyed infrastructure, and a currency that had lost most of its value. Under American occupation, the yen underwent strict monetary reform, and in 1949 its exchange rate was fixed at 360 yen per US dollar1,588+0.52% under the Bretton Woods system of fixed exchange rates. This was not a mere technical figure; it became the cornerstone of Japan’s export-led growth strategy, since a relatively low exchange rate made Japanese export goods highly competitive in world markets.
During this period, Japanese economic policy focused on rebuilding heavy industry, subsidizing exports, and tightly controlling foreign capital to protect the fragile new economy. The Bank of Japan worked in close coordination with the Ministry of Finance and the Ministry of International Trade and Industry to channel credit toward strategic sectors — a model of deliberate state guidance that differed sharply from Western laissez-faire principles.
The Japanese Economic Miracle and Supportive Monetary Policy
Between the 1950s and the 1970s, Japan recorded extraordinary growth rates known as the “Japanese economic miracle,” transforming the country from a war-ravaged economy into the world’s second-largest. The fixed, low yen exchange rate played a pivotal role in this transformation, allowing companies such as Toyota, Sony, Honda, and Panasonic to conquer global markets with competitive prices while maintaining healthy profit margins.
This fixed system did not last forever. In 1971 the United States ended the dollar’s convertibility into gold in what became known as the “Nixon Shock,” and the Bretton Woods system gradually collapsed. The yen moved into a managed float from the early 1970s onward, leading to a gradual appreciation. Japan’s strong, export-driven economy absorbed this appreciation relatively well throughout the 1970s and 1980s.
The 1985 Plaza Accord: A Major Turning Point
1985 marked a decisive turning point in the yen’s history. The major industrial powers — the United States, Japan, West Germany, France, and Britain — met at New York’s Plaza Hotel and agreed on coordinated intervention to devalue the US dollar against the yen and the German mark, aiming to shrink the huge US trade deficit with Japan. As a result, the yen appreciated sharply within a few years, hurting the competitiveness of Japanese exports.
To counter the slowdown caused by the stronger yen, the Bank of Japan cut interest rates sharply and injected abundant liquidity into the economy. This expansionary monetary policy fueled a massive speculative bubble in Japanese stock and real estate markets in the late 1980s, later known as the “bubble economy.”
The Lost Decades: Deflation and Near-Zero/Negative Interest Rates
In the early 1990s, Japan’s asset bubble burst. Stock and real estate prices collapsed, and the economy entered a long period of near-permanent stagnation known as the “Lost Decade,” later extending into the “Lost Decades” that lasted more than twenty years. This period was marked by chronic price deflation — a general decline in prices rather than a rise — which encouraged consumers and businesses to delay spending and investment in anticipation of cheaper prices later, deepening the stagnation further.
To combat this deflation, the Bank of Japan gradually cut interest rates until they approached zero by the late 1990s, then adopted “quantitative easing,” buying enormous quantities of government bonds and financial assets to inject liquidity into the banking system. As inflation remained persistently weak, the central bank took the unprecedented step in 2016 of imposing a negative interest rate on part of commercial banks’ reserves held with it, in an attempt to push them toward lending and investment rather than hoarding cash. For years, Japan stood as the global reference case for what can happen when a large economy settles into weak growth and near-zero inflation for an extended period.
A decade of weakening, in one line
The interest-rate story of the lost decades has a price attached to it, and the price is visible. DinarView has recorded the yen every day since August 2016. Because the pair is quoted as yen per dollar, a rising line means each dollar buys more yen — that is, a weaker yen.
The yen’s strongest reading in the record is 100.3 per dollar on 22 September 2016; its weakest is 163.9 on 29 July 2026. In yearly averages the pair sat between 107 and 112 from 2016 to 2021, then moved in one direction: 131 in 2022, 140 in 2023, 151 in 2024, 150 in 2025 and 159 so far in 2026. That is a currency roughly a third weaker against the dollar over the window — not a crisis, but the clearest example in any major currency of what a persistent interest-rate gap does to a price.
The Yen in Global Trade and the Carry Trade
Thanks to near-zero or negative interest rates sustained for decades, the yen became a preferred currency for cheap borrowing among international investors, who borrow in yen at very low cost and then invest the funds in other currencies’ assets offering higher returns — a practice known as the “yen carry trade.” This makes the yen highly sensitive to any shift in global interest rate differentials: when major central banks, chiefly the US Federal Reserve, raise rates rapidly while the Bank of Japan keeps its policy accommodative, the yen tends to weaken markedly against the dollar and the euro, as seen in recent years. Conversely, any sudden unwinding of this trade — as has happened during some global financial crises — can trigger a sharp, sudden appreciation of the yen, as investors rush to close their yen-funded borrowed positions.
Beyond its role in financial markets, the yen remains one of the world’s most important export currencies, with Japan ranking among the largest exporters of automobiles, machinery, electronics, and precision industrial equipment. The yen has also traditionally been classified as a “safe-haven currency” that investors turn to during global market turmoil, though this characteristic has become less pronounced in recent years due to the yen’s structural weakness stemming from wide interest-rate gaps with other economies.
What This Means for Importers of Japanese Goods in Iraq
Iraq purchases large quantities of Japanese goods every year, chiefly automobiles (especially used vehicles), spare parts, electrical equipment, electronics, and industrial and agricultural machinery. Movements in the yen’s exchange rate against the US dollar — the reference currency in Iraq’s foreign trade alongside the Iraqi dinar — directly affect the cost of these imports. When the yen weakens against the dollar, Japanese goods become relatively cheaper for the Iraqi importer paying in dollars or their dinar equivalent, and the opposite holds when the yen strengthens.
The Central Bank of Iraq’s official exchange rate has been set at 1,310 dinars per dollar since February 2023, while the parallel market rate remains higher than the official rate depending on fluctuations in dollar supply and demand. For an Iraqi trader or importer planning to purchase goods from Japan, following the yen’s overall trend — not just its momentary rate — helps in choosing the most suitable timing for contracting or transferring payments, especially for large deals settled in installments.

For an importer in Iraq the yen only matters through two rates at once, so it is worth seeing them side by side. The table is DinarView’s own yearly average of the yen-dinar cross, with the dollar leg shown separately.
| Year | Dinars per ¥1 | Dinars per ¥1,000,000 | Yen per $1 | Dinars per $1 |
|---|---|---|---|---|
| 2022 | 10.76 | 10,761,463 | 138.1 | 1,486 |
| 2023 | 10.97 | 10,965,999 | 140.2 | 1,538 |
| 2024 | 9.91 | 9,908,344 | 151.2 | 1,497 |
| 2025 | 9.59 | 9,589,472 | 149.9 | 1,438 |
| 2026 | 9.63 | 9,630,563 | 158.7 | 1,529 |
DinarView yearly averages. The million-yen column is the practical one: a used Japanese car is usually priced in millions of yen. The dinar record starts in May 2022; 2026 runs to early September.
Read the third column and the practical effect is plain. A car invoiced at one million yen cost about 10,761,463 dinars in 2022 and about 9,630,563 in 2026 — roughly 11 percent less, on an unchanged yen price. Almost all of that saving came from the yen’s own 13 percent fall against the dollar; the dinar moved the other way by about 3 percent and gave a little of it back. Japanese goods have become cheaper in Iraq in spite of the dinar, not because of it.
The yen’s weight in the market has not fallen with its price. In the Bank for International Settlements’ 2025 triennial survey it was still on one side of 16.8 percent of all foreign exchange trades, essentially unchanged since 2019 and third behind the dollar and the euro. A cheap currency and a heavily traded one are different things.
Frequently Asked Questions About the History of the Japanese Yen
Why was the yen’s exchange rate fixed at 360 per dollar after the war?
Because Japan was under American occupation and part of the Bretton Woods fixed exchange rate system, and this level was chosen to help the war-damaged Japanese economy recover through competitive exports.
What caused Japan’s “Lost Decades”?
The bursting of the stock and real estate bubble in the early 1990s led to long-term deflation and chronic weak growth, despite repeated attempts by the central bank to stimulate the economy through rate cuts and quantitative easing.
What is the “yen carry trade” and why do investors care about it?
It is a strategy of borrowing in yen at very low interest and investing the funds in other currencies offering higher returns; it is highly sensitive to global interest rate differentials and can unwind sharply and suddenly.
How does a weaker yen affect Iraqi importers?
A weaker yen against the dollar makes Japanese goods, such as cars and electronics, relatively cheaper for the Iraqi importer who pays in dollars or their dinar equivalent.
