Reverse Carry Trade: Lewis Jackson Breaks Down Japan’s Biggest Risk and XRP’s Hidden Variable

In a new episode of The Macro, crypto analyst Lewis Jackson examines Japan’s reverse carry trade, the Bank of Japan’s historic policy shift, and why XRP’s long-term viability depends on one under-discussed factor: velocity. By linking yen-funded liquidity flows, tokenized settlement rails, automated market makers, and on-demand liquidity corridors operated by SBI Remit, Jackson explores whether XRP could meaningfully support large-scale FX redirections — and what that would actually imply for the asset’s price, liquidity profile, and role in next-generation settlement systems.

Japan’s Reverse Carry Trade and XRP’s Velocity Problem: Inside Lewis Jackson’s New Analysis

In this episode of The Macro, Lewis Jackson delivers one of his most technically grounded assessments yet, blending macroeconomic research with blockchain infrastructure analysis. Rather than feeding into the hype that often surrounds ripple xrp news, Jackson focuses on the mechanics that genuinely matter: interest-rate differentials, liquidity routing, tokenized deposits, AMM-powered settlement, and how institutions choose to reuse — or not reuse — digital assets across programmable payment networks.

The centrepiece of the episode is an idea Jackson believes the XRP community often overlooks: flows don’t determine XRP’s required value — velocity does.

1. Understanding the Carry Trade — The System Behind the Story

Jackson begins with a clear and intuitive explanation of the carry trade, the decades-long macro pattern that shaped global liquidity flows.

In a classic carry trade, investors:

  • borrow in a low-interest-rate currency (for decades, Japan),
  • convert that money into a higher-yielding currency,
  • invest in foreign bonds, RWAs, or treasuries,
  • and pocket the spread.

Japan became the world’s preferred funding source for this strategy. Its zero-rate regime, which began in 1999 and dipped into negative territory in 2016, allowed institutions to borrow enormous sums at essentially no cost.

That era changed abruptly on 19 March 2024, when the Bank of Japan raised rates for the first time in 17 years. Jackson treats this not as monetary trivia, but as a genuine transformation in the liquidity architecture that underpins everything from FX markets to blockchain-based settlement experiments.

2. The Reverse Carry Trade — Unwinding a Multi-Trillion Dollar Position

Years of ultra-cheap borrowing created a huge global imbalance. Analysts estimate that $4.2–$4.5 trillion flowed into yen-funded positions. As Japan shifted its policy stance, institutions began unwinding these positions, triggering FX volatility and forcing liquidity rerouting across multiple markets.

Jackson cites BIS documentation describing this as a “carry trade unwind” — a process that exposes structural weaknesses in both traditional financial rails and emerging tokenized alternatives.

The key questions become:

  • Can traditional payment systems absorb large FX redirections without liquidity fractures?
  • Do correspondent-banking rails still have the resilience needed during unwind cycles?
  • And could neutral FX conversion assets, including XRP, ease liquidity stress in certain corridors?

These questions form the intellectual bridge between Japan’s macro shift and the XRP-related narratives circulating online.

3. Why XRP Enters the Conversation

Jackson is careful to avoid sensationalism. XRP does not automatically become “the solution” just because Japan is a pro-Ripple jurisdiction. Instead, he notes that XRP’s presence in Japan is measurable, documented, and operational.

SBI Remit currently uses XRP in live corridors between:

  • Japan and the Philippines
  • Japan and Indonesia
  • Japan and Vietnam

These corridors run under regulated oversight and provide a practical example of XRP acting as a neutral bridge asset in real economic flows. That real-world usage is why XRP inevitably appears in discussions about macro shifts — but it does not, by itself, guarantee dramatic price implications.

Which brings Jackson to the most important part of the episode.

4. The Missing Variable in Most XRP Price Predictions: Velocity

According to Jackson, almost every high-end XRP price prediction makes the same mistake:
they assume the price depends on the size of the flows, not the speed of the asset.

Velocity refers to how many times a single unit of liquidity can be reused inside the settlement architecture. In traditional finance, BIS frameworks allow each $1 in nostro/vostro to circulate multiple times per day. In programmable-money or XRPL AMM environments, that velocity could be significantly higher.

Jackson explains the implications simply:

  • High velocity = fewer XRP required → lower price requirement
  • Low velocity (batching, ZK rollups) = more XRP required → higher price requirement

This is the heart of the analysis — and the nuance many crypto influencers never discuss.

The question is not:
“How big is the flow?”

It’s:
“How many times will institutions reuse the same token before the day ends?”

This one variable reshapes the entire XRP valuation framework.

5. Two Possible Futures for XRP

Jackson outlines two architectural paths — each leading to very different price outcomes.

Path A — High Velocity: System Efficiency Over Asset Value

In this scenario:

  • AMMs manage liquidity
  • XRPL operates at high throughput
  • stablecoins dominate settlement
  • CBDCs interoperate directly
  • AI-driven routing optimises paths continuously

XRP still functions as a conversion asset, but its required price is modest because the system recycles liquidity so frequently.

Path B — Lower Velocity: ZK Rollups and Batching Drive Value Upward

If institutions favour privacy layers, ZK rollups, batched settlement, or XRPL-anchored rollup systems, settlement frequency drops and locked liquidity rises. That environment requires:

  • larger buffers,
  • deeper AMM pools,
  • and more XRP per batch.

In this world, XRP must hold more value per unit for the system to work.

Jackson frames this scenario as the foundation of high-value XRP theories — rooted not in hype, but in settlement mechanics.

6. XRP’s Macro Relevance Beyond the Carry Trade

Jackson closes by reminding viewers that while Japan’s reverse carry trade serves as an excellent teaching example, it is not the ultimate driver of XRP’s value.

The real determinants include:

  • XRP’s role in neutral FX and settlement finality
  • the structure of future CBDC networks
  • tokenized-deposit architectures
  • AI-routed settlement pathways
  • XRPL AMM mechanics
  • stablecoin frameworks like RLUSD
  • private-ledger integration
  • ZK-enabled privacy layers
  • and whether institutions ultimately adopt batching or high-frequency liquidity reuse

These forces will shape XRP’s value far more than any single macro event.
