Understanding JPY Carry Trades: Why They’re More Relevant Than Ever

Carry trading has long been a favorite strategy of both novice and experienced forex traders. At its core, the concept might sound deceptively simple: borrow in a currency with a low-interest rate and invest in a currency with a higher interest rate. Yet, as with most strategies in finance, what appears straightforward on the surface can carry layers of hidden risk. The Japanese yen (JPY) plays a leading role in this discussion due to Japan’s historically low-interest rate environment, making the JPY carry trade especially noteworthy. In this blog post, we’ll examine the latest trends in the JPY carry trade, explore forward-thinking strategies for 2025, and take a closer look at how the carry trade actually works. Along the way, we’ll challenge some widely held beliefs and highlight why remaining flexible is crucial in today’s ever-shifting financial environment.

THE JULY TWISTS AND TURNS: WHAT HAPPENED TO THE JPY CARRY TRADE?

Many forex traders keep a close eye on monthly developments. July, in particular, revealed some interesting twists for anyone following JPY carry trades. It’s widely believed that when interest rates remain low in Japan, the yen should ideally continue to weaken against higher-yielding currencies like the Australian dollar (AUD) or the New Zealand dollar (NZD). After all, borrowing in yen is usually cheaper, so investors borrow JPY in large quantities and then buy another currency that yields higher returns.

However, recent data from July showed a surprising trend: the yen actually appreciated against certain currencies. Why does this matter? Because it challenges the assumption that JPY will always flame out in the face of higher-yielding counterparts. Several economic indicators contributed to this anomaly:

• Inflation Figures in Japan: While Japan has wrestled with deflation for years, recent monthly and quarterly data suggest that inflation may be inching upward, albeit modestly. If that trend continues, the Bank of Japan may eventually consider changing its longstanding ultra-loose monetary policy. Even a hint of monetary tightening could drive up the yen’s value.
• Global Risk Sentiment: Traders globally shift between “risk-on” and “risk-off” modes. In certain risk-off environments—often triggered by geopolitical tensions or concerns about global growth—the yen gains strength as a safe-haven currency. July saw periods of global uncertainty, prompting some movement into JPY and contributing to its surprise appreciation.
• Shifts in Central Bank Policies: At times, central banks in higher-yielding currency regions (such as Australia or New Zealand) do not raise rates as much as the market anticipates, or they signal they may slow down rate hikes. When that happens, the carry trade advantage can narrow, causing traders to rethink their positions.

Never assume that the low-rate currency, even one as historically “cheap” as the yen, can’t reverse course.

As an actionable takeaway, those watching the JPY carry trade should do more than keep an eye on interest rates. Economic reports, geopolitical developments, and central bank pronouncements can all collide to produce unexpected currency movements.

LOOKING FORWARD: FOREX CARRY TRADE STRATEGIES FOR 2025

The foreign exchange market never sleeps, and neither should our analysis of it. As we look ahead to 2025, emerging strategies may redefine how we approach the JPY carry trade. Here are a few innovations and perspectives to consider:

• Diversifying Borrowing Currencies: Traditionally, the yen has been the go-to currency for funding a carry trade. Yet, other regions are now flirting with ultra-low interest rates, especially with certain European economies grappling with slow growth. By expanding the range of currencies used for borrowing, traders can mitigate country-specific risks. This approach defies the long-held assumption that JPY is the only low-yield choice worth considering.
• Hedging with Currency Options: One change we’re seeing is the increased use of option strategies to manage downside risk. Carry trades are not immune to volatility, and adding a layer of options-based protection can help buffer against drastic currency swings. For instance, pairing a short-dated put option on the currency you’re investing in can act as a hedge if the pair suddenly moves against you.
• Tapping into Emerging Markets Carefully: Higher returns are often found in riskier corners of the currency market—think emerging economies in Southeast Asia or Eastern Europe. While the yield spread can look enticing, these currencies can be far more volatile. The advanced strategy for 2025 might be to split the carry trade across multiple emerging market currencies, diversifying to prevent concentration risk.
• Automated Trading and Algorithmic Approaches: Technology and algorithmic trading provide real-time scanning for interest rate spreads, news events, and volatility metrics. Implementing an automated system with robust risk controls can unlock opportunities that a manual approach might miss. But remember, no algorithm can guarantee success; it must be tested thoroughly under various market conditions.

The overarching lesson for 2025? Stay open to evolving strategies. The currency market is alive with dynamic variables, so rigid adherence to old ways can become a liability. Innovate, diversify, and protect your positions with tailored hedges.

UNRAVELING THE MECHANICS: HOW THE CARRY TRADE REALLY WORKS

At first glance, a carry trade might sound like a straightforward approach: borrow in Currency A (with a low interest rate) and convert the proceeds into Currency B (with a higher interest rate). You then earn interest on Currency B, aiming to pocket the difference. However, let’s break down the process step by step to illustrate the hidden complexities:

• Identify the Funding Currency: This is typically JPY or other low-interest-rate currencies. The interest rates set by the relevant central bank heavily influence this choice.
• Borrow at the Funding Rate: The trader takes a loan in the funding currency. Depending on the broker or financial institution, the actual rate at which you borrow might vary from the central bank’s rate.
• Convert to the Target Currency: Next, you convert the borrowed funds to a currency that offers higher returns—or deposit the money in a financial product denominated in that currency.
• Earn the Interest Differential: In an ideal scenario, your earnings come from the higher interest rate you collect minus the lower interest rate you owe. Over time, many traders look at the daily rollover credit (or debit) in their trading account.
• Manage Exchange Rate Risk: Exchange rates can swing. If the funding currency suddenly strengthens, your profits from the interest rate differential could be wiped out—or you could face a net loss. This risk is often overlooked by traders who solely focus on the interest rate spread.

A common misconception is that the carry trade is “free money.” The truth is, it reaps rewards only when both interest rates and exchange rate movements align favorably. A real-life scenario might involve borrowing yen at a near-zero rate, then investing in Australian dollars at a more robust interest rate. If global growth slows and Australia’s central bank unexpectedly cuts rates, the once-wide interest rate gap narrows, and if the AUD depreciates against JPY, the carry trade’s advantage might evaporate. In 2008, for instance, the Japanese yen rallied strongly when risk sentiment collapsed, catching many carry traders off guard. That event remains a cautionary tale about how quickly things can change.

RETHINKING WHAT WE KNOW: WHY PAST BELIEFS MAY NO LONGER HOLD

Market participants often cling to previously successful strategies, hoping they’ll deliver consistent returns. The JPY carry trade, in particular, has been seen as a perennial winner in times of global optimism. However, recent market fluctuations, including episodes of JPY appreciation in July, beg an important question: Are these “surefire” carry trades as bulletproof as we think?

• Changing Global Monetary Policies: Central banks worldwide have become more responsive—and sometimes reactive—to short-term economic shifts. With political uncertainty and supply chain disruptions, unexpected changes in monetary policy can occur quickly. Yesterday’s rules of thumb about ultra-low rates in Japan and stable, higher rates elsewhere might not hold tomorrow.
• Technological Disruptions: Automated trading systems and high-frequency algorithms can trigger rapid price movements that catch humans off guard. These mechanized responses are less “patient” than traditional traders; they quickly buy or sell large sums of currency the moment key economic data is released. The outcome? Unpredictable volatility that can disrupt any carry position.
• Shifting Safe-haven Status: Historically, the yen has been viewed as a safe-haven currency. But the consistency of that status can be overshadowed by sudden capital flows into the U.S. dollar or Swiss franc, especially if geopolitical tensions change market sentiment. Believing JPY will “always” function as a safe haven can lead to miscalculations.

A critical mindset can save you from big surprises when “that’s how it’s always worked” no longer applies.

History is instructive. The global financial crisis in 2008 shattered confidence in classic carry strategies. Before that event, many forex participants believed that central banks moved rates slowly and predictably, giving the carry trader ample time to adjust. The reality was far harsher: rates shifted abruptly, liquidity evaporated, and carry trades crumbled as investors fled to safer assets. The moral? Stay aware that past performance isn’t a guaranteed roadmap for the future.

A NEW PERSPECTIVE ON JAPANESE YEN CARRY TRADES

Given recent events, shifting strategies, and the nuanced mechanics of the carry trade, the time is ripe for a reevaluation of JPY carry trades. If we’re to learn anything from the surprising trends in July and the lessons of the past two decades, it’s that flexibility and continuous learning are paramount.

Here are some key takeaways for your approach to JPY carry trades:

• Always Diversify Your Risk: Rather than relying on a single pair, consider multiple funding and target currency pairs. This helps guard against sudden monetary shifts in one economy.
• Stay Vigilant About Market Sentiment: Whether in a risk-on or risk-off environment, keep an ear to the ground for global events. Sudden tensions or structural shifts can quickly alter currency demand.
• Focus on Risk Management Tools: Options, stops, and disciplined position sizing aren’t luxuries—they’re essentials. Especially with carry trades, where a small change in the exchange rate can wipe out accumulated interest gains.
• Question Long-held Assumptions: Forex markets are sometimes driven by psychological factors as much as by fundamentals. A critical mindset can save you from big surprises when “that’s how it’s always worked” no longer applies.

PREPARING FOR THE NEXT WAVE: FINAL THOUGHTS

The JPY carry trade stands as a compelling study in contrasts. On one hand, it’s often viewed as a stable way to profit from the difference in interest rates. On the other, it’s subject to the whims of global sentiment and central bank shocks that can quickly turn a profitable trade into a setback. Keeping a flexible, informed perspective can help you navigate these waters more confidently.

The challenges of 2023 have already tested many assumptions. As we edge toward 2025, expect further evolution in how the yen interacts with world markets. Traders who maintain a balanced portfolio, remain watchful for economic signals, and employ creative hedging strategies position themselves to thrive in a world where tomorrow’s interest rate environment is anything but guaranteed.
