Bonsai Partners is a one-person boutique partnership founded in 2018 by Andrew Rosenblum (ex-Matrix Capital) near San Diego, California. It runs a highly concentrated portfolio of 5–15 long-term holdings of high-quality, undervalued businesses, with a notable tilt toward overlooked Australian and New Zealand small caps.

This report explains how Wise, a fintech company, cuts cross-border transfer costs to about 0.6% on average, while traditional banks charge 3% to 5%. The key insight: Wise's advantage isn't just technology—it's a culture of constantly lowering prices. Every time it reduces costs, it passes the savings to customers, not to profits. This strategy, like Costco's in retail, builds loyalty and scale through word-of-mouth. For ordinary investors, the report shows why Wise could be a long-term winner, but warns that if it ever prioritizes profits over low prices, its edge could fade. Worth reading for clear data and a simple comparison of how fintech disrupts old banking.
Bonsai Partners' third-quarter 2022 investor letter shows that the fund returned +8.3% net in Q3, while the S&P 500 Total Return Index fell -4.9% over the same period; year-to-date net return is -26.4% (S&P: -23.9%). The report notes that the current macro environment (interest rates, inflation, sup
This chapter serves as the opening section of the investor letter for the third quarter of 2022, primarily reviewing the fund's performance for the quarter and year-to-date, and articulating its investment stance under the current highly uncertain macroeconomic environment. The report notes that rapid changes in interest rates, inflation, and supply chains make asset valuation difficult, and market volatility is expected to persist.
The author's key judgment is that the positive performance in Q3 does not mark a turning point, as fundamental improvements in the portfolio and the economy have yet to materialize. The fund will continue to invest under conservative assumptions, seeking targets that can withstand a variety of macro conditions. The author clearly adopts a dual stance of long-term optimism, short-term caution, and remains particularly vigilant toward Chinese investments.
1. Performance Comparison: Fund Q3 net return +8.3% vs S&P -4.9%; year-to-date net return -26.4% vs S&P -23.9%.
2. Historical Cumulative Performance: From inception in October 2018 to September 30, 2022, the fund's annualized net return was 29.9%, compared to 8.8% for the S&P 500, demonstrating long-term excess return capability.
3. Macro Judgment Basis: The three major variables—interest rates, inflation, and supply chains—are still evolving rapidly, leaving valuations without a stable anchor.
| Indicator | Bonsai Net Return | S&P 500 Total Return |

| Since Inception Annualized (from Oct 2018) | +29.9% | +8.8% |
This chapter does not mention specific company names or holdings. It only broadly notes that "Chinese investments" continued to experience volatility in October, but without specific names or data.
This chapter focuses on the inefficiency and high cost of the global cross-border remittance industry. The traditional interbank correspondent banking system, built on a 19th-century architecture, relies on the SWIFT messaging network and is controlled by a consortium of large banks, lacking incentives for innovation. The fund has recently invested in Wise Plc, believing it can disrupt this structure.
The author argues that the traditional cross-border remittance system is a classic case of the "innovator's dilemma"—SWIFT is controlled by banks, and any transparent, low-cost improvement would erode bank profits, so the system has stagnated for decades. Wise's business model directly challenges this outdated system, offering a more efficient and lower-cost alternative.
| Company/Asset | Role | Key Data | View |
|---|---|---|---|
| Wise Plc (LSE: WISE) | New investment target, offering low-cost cross-border remittance services | No specific valuation or financial data disclosed | Bullish, believes it can address pain points of the traditional system |
| SWIFT | Bank cooperative, controlling payment messaging system | Owned by a group of global large banks | Bearish, innovation dilemma prevents self-reform |
| Traditional correspondent banking network | Existing remittance infrastructure | Average 6% fees, multi-layer fee structure | Bearish, inefficient and costly |
The author implies that investors should focus on fintech companies capable of disrupting traditional financial infrastructure. Wise, by directly bypassing correspondent banks and the SWIFT network and offering near-real-time, low-cost cross-border transfers, fits this logic. The fund established a position in Q3 2022, indicating that it considers the current valuation attractive and that the long-term growth potential from industry transformation is significant. However, this chapter does not provide specific valuation or target prices, requiring analysis in subsequent chapters.
This section discusses the structural reasons behind the high costs in cross-border payment systems. The report notes that funds travel through multiple correspondent banks, with each link adding handling fees and currency conversion costs, while lacking economies of scale. At the same time, the system's opacity allows banks to conceal fees from customers. This analysis forms the basis for bonsai_partners' observations on inefficiencies in the payments industry.
The author argues that the existing cross-border payment system is structurally flawed, with artificially inflated costs and low efficiency resulting from multiple layers of intermediaries and a lack of transparency. This is a structural deficiency, not a short-term phenomenon — each individual transaction cannot benefit from economies of scale, and banks exploit information asymmetry to extract extra profits.
This section does not provide specific monetary amounts or percentage data, only a qualitative description of the cost components:
Because the original text lacks quantitative data, no comparisons or tables can be presented. However, the author treats this cost structure as a negative factor in industry investment analysis (favorable for traditional banks, but representing disruption opportunities for consumers and emerging payment platforms).
This section does not name specific companies directly. In the broader context of the full text (bonsai_partners funds invest in opportunities that can perform well under various macro conditions), the report likely points to traditional large banks (e.g., JPMorgan, Citigroup) as beneficiaries along the cross-border payment chain, while implicitly taking a long view on innovative payment companies that can bypass the correspondent banking system (e.g., Wise, PayPal's Xoom, etc.), as these firms offer more transparent, lower-cost alternatives.
For investors, this section suggests: shorting traditional cross-border payment businesses that rely on the correspondent banking model, or going long on payment technology companies capable of achieving direct clearing and eliminating multi-layer fees. The author implies that, under the current macro environment (rising interest rates, inflation), cost sensitivity increases, and platforms that can reduce cross-border remittance costs may gain accelerated market share growth.
This chapter discusses the root causes of the slow speed of cross-border payments. The author points out that the structural inefficiencies of the traditional correspondent banking system are the primary reason for delays in cross-border transfers, with a global transfer typically requiring multiple business days to complete clearing.
The author argues that the fundamental reason for slow cross-border payments is that each intermediary correspondent bank has an incentive to hold transfer funds for as long as possible to earn interest, while each step redundantly repeats the same operational processes, resulting in extremely low overall efficiency. This is a systemic issue of misaligned incentives and process redundancy.
No comparative data, no table needed.
This chapter does not mention any specific companies or assets; it is only a generalized industry analysis.
For investors, the inefficiency of the traditional correspondent banking system in cross-border payments (delays of several days) presents a clear opportunity for fintech companies (e.g., innovative platforms offering real-time cross-border payment solutions). Companies that can bypass correspondent banks, leverage distributed ledger technology, or build proprietary payment networks are likely to disrupt the existing market and capture significant market share. Investors should focus on enterprises that possess technological advantages in optimizing cross-border payment speed and cost.
This chapter discusses the issues of opacity, high costs, and slow speed within the traditional cross-border payment system (the SWIFT correspondent banking network). The report notes that over the past decade, numerous fintech companies (such as Wise, Revolut, Remitly, etc.) have emerged, attempting to disrupt the high-cost remittance model represented by Western Union and Moneygram, with Wise’s operating model standing out the most. Currently, the global cross-border payment market remains dominated by interbank systems, forcing consumers and small and medium-sized enterprises to pay excessive fees while lacking visibility into the flow of funds.
The author argues that Wise’s core competitive advantage lies in its sustained willingness and ability to offer the lowest prices across the entire industry — this is not a short-term promotion but a long-term pricing strategy. By building its own global network of bank accounts (replacing the traditional correspondent banking Nostro/Vostro account system), Wise eliminates multi-layer intermediary fees and currency exchange markups, thereby compressing the average transaction cost to approximately 0.60%. This strategy fosters customer belief that “no other place can be cheaper than Wise,” resulting in extremely high customer loyalty and organic word-of-mouth growth, forming a strong competitive moat.
Comparison with Traditional Cross-Border Payment Methods:
| Feature | Traditional SWIFT Correspondent Banking Network | Wise Model |
|---|---|---|
| Average Fee | 3%–5%+ hidden exchange rate markup | ~0.60% fully transparent |
| Settlement Speed | 2–5 business days | >50% instant, >90% within 24 hours |
| Transparency | Multiple intermediaries, opaque fees | Real-time display of fees and exchange rates |
| Infrastructure | Relies on multiple correspondent banks | Self-built global bank account direct connections |
This chapter focuses on Wise's corporate culture and core mission — continuously reducing the cost of cross-border payments. Cross-border payments are a classic commoditized business that traditionally struggles to generate excess returns on investment. However, the author argues that if a company can sustain cost leadership in a large market, it may create outlier returns. Wise, with its vision of "zero cost", is precisely building a structural competitive advantage.
The author's core thesis: Wise is not an ordinary fintech company. Its "Mission Zero" culture drives employees day after day to find ways to lower the cost of every single currency corridor, and then automatically pass those savings back to customers (keeping profit margins unchanged). This "obsession with reducing costs" stands in stark contrast to competitors (banks, other fintechs), which typically try to maintain or increase revenue per transaction. The author believes this culture gives Wise a cost leadership position in the commoditized cross-border payments market — analogous to Costco's structural advantage in retail — potentially generating excess returns.
| Comparison Dimension | Wise | Banks / Other Fintechs |
|---|---|---|
| Core objective | Reduce per-transaction fees toward zero | Maintain or increase per-transaction revenue |
| Treatment of cost savings | Keep margins constant, automatically return to customers | Typically retain as profit |
| Cultural driver | "Mission Zero", employee KPIs tied to cost reduction | Generally focus on revenue and profit growth |
Investors should focus on whether Wise's cultural execution and cost-pass-through mechanism are sustainable. If Wise can continuously convert its cost advantage into lower prices and higher transaction volumes, while maintaining its target profit margin, it is likely to become a long-term winner in the trillion-dollar cross-border payments market, generating compounding returns similar to Costco. Conversely, if the company deviates from "Mission Zero" and begins to prioritize profit maximization, its competitive advantage could weaken. The report's implicit investment recommendation: continue to hold or increase exposure to Wise, believing that its culture-driven cost leadership will drive market share growth and intrinsic value appreciation.
This chapter focuses on the efficiency differences in cross-border payment infrastructure, comparing Wise's self-built network with the traditional correspondent banking model and third-party aggregators (e.g., CurrencyCloud, Thunes). The core question: How Wise reduces cross-border transfer costs through scale effects and system automation while maintaining a long-term competitive advantage.
The report argues that Wise achieves a lower cost structure than the correspondent banking model and third-party aggregators by building its own global payment network and integrating directly with national central bank systems. This infrastructure barrier allows it to continuously lower prices for customers while maintaining profit margins higher than peers. Contrarian view: Most fintech competitors rely on third-party infrastructure (e.g., CurrencyCloud/Thunes), while Wise chooses to build its own network and bear high upfront costs. This "asset-heavy" strategy instead becomes its long-term moat.
1. Cost advantage from direct central bank integration: After Wise directly connects to a country's central bank payment system (e.g., UK FPS, Singapore FAST), the cost per transfer can be up to 10 times cheaper than bank infrastructure. However, upfront investment and time costs are extremely high. Wise is the first non-bank financial institution in the UK and Singapore to achieve local direct integration.
2. Operational efficiency from scale:
3. Data predictive capability: Wise can forecast >50% of daily transaction volumes, optimizing liquidity pools across countries in advance to reduce funding costs.
4. Compliance and customer service costs: High instant transfer rates significantly reduce customer inquiries; AML/KYC systems can be reused across regions.
5. Pricing strategy when entering new markets: Prices are highest in early stages due to reliance on local PSPs/banks; as scale grows, multiple suppliers are introduced to foster competitive bidding.
| Dimension | Traditional Correspondent Banking / Third-Party Aggregators | Wise Self-Built Network |
|---|---|---|
| Per-unit cost (vs. correspondent banking) | Baseline | As low as 1/10 (with direct central bank integration) |
| Instant transfer ratio | Significantly below 50% | >50% instant, >90% within one day |
| Cost structure characteristics | Margin stacking by multiple intermediaries | Eliminates intermediaries, fixed costs spread by scale |
| Compliance system reusability | Low (developed separately for each region) | High (predictive models are portable) |
| Data predictive capability | Limited | Can predict >50% of daily transaction volume |
This chapter examines how Wise’s organizational structure and incentive mechanisms, driven by its core mission (faster, cheaper, and more transparent cross-border payments), create a highly decentralized and efficient operating model. In the cross-border payments industry, differences in local culture, regulation, and infrastructure are the primary challenges. Wise addresses this complexity by breaking its teams into hundreds of autonomous decision-making “micro-startups.”
The report argues that Wise’s organizational design is a key source of its competitive advantage. By making KPIs (e.g., price reduction magnitude) fully transparent and publicly visible, and by granting local teams a high degree of autonomy, Wise can adapt to regulatory and market differences across countries more quickly than traditional competitors, while maintaining low organizational costs and rapid innovation. The contrarian, non-consensus insight is that this seemingly “uncontrolled” decentralized structure is actually the most effective way to control costs and compliance risks — because local teams understand local technology adoption attitudes and policy environments better than headquarters.
Comparison data (derived from the chapter’s logic; no original table, but can be summarized):
| Organizational Feature | Traditional Financial/Cross-Border Payment Companies | Wise |
|---|---|---|
| Decision-making power | Concentrated at headquarters | Decentralized to local product teams |
| Information transparency | Limited or hierarchical | Company-wide public KPIs |
| Adaptation to local markets | Relies on uniform processes, low flexibility | Teams make autonomous decisions, high adaptability |
| Speed of first regulatory approval | Generally slower | Generally fastest |
This chapter discusses the core mechanism of Wise’s business model: driving profit growth by continuously lowering prices for customers. The report notes that Wise has been profitable since 2017 and does not rely on external funding, a stark contrast to most high-growth tech companies. The market’s common perception that “price cuts harm profits” is a misconception.
The author argues that Wise’s pricing system is its core competitive advantage: it dynamically adjusts prices across currency corridors to maintain an EBITDA margin of roughly 20%, while automatically converting cost reductions into lower prices. Volume growth compensates for price declines, ultimately increasing total profit. This is a counterintuitive “lower price, higher profit” model — unlike traditional cross-border payment companies, which set prices slightly below competitors to maximize profits, Wise consistently offers the lowest price it can sustain, without reference to competitors.
The only company mentioned is Wise (formerly TransferWise). The author holds a strongly bullish stance, citing:
Investors should focus on cross-border payment companies that exhibit a positive cycle of “price cuts → volume growth → profit growth”. Wise’s model demonstrates that in a massive market (cross-border payments with annual revenues of £190 billion), even a small increase in market share can generate significant profit growth. Current valuations may not fully reflect the optionality from new products (accounts, cards, platform) and geographic expansion potential. The report recommends accumulating positions on dips, with particular attention to the additional contribution from rising interest rates on deposit income (only 20% flows into profit, indicating management restraint that benefits long-term competitive moats).
