Positive carry: definition, examples, and investment strategies

Positive carry: definition, examples, and investment strategies sits at the intersection of yield-seeking behaviour and leverage management across global markets. This overview examines how investors generate a net income from assets after financing costs are accounted for, and why large asset managers such as BlackRock, Vanguard, J.P. Morgan, Goldman Sachs and Morgan Stanley incorporate carry considerations into portfolio construction. It outlines mechanics in FX, fixed income and real estate, illustrates practical examples, and highlights the trade-offs that arise when interest rates, volatility or credit conditions shift. Readers will find concrete links to related futures concepts such as basis and backwardation, along with toolkits for quick calculations and embedded media to visualise how carry strategies operate in live markets. The discussion focuses on operational specifics relevant to futures and derivatives desks, risk teams, and institutional allocators such as PIMCO, Fidelity Investments, Charles Schwab, Citigroup and State Street, emphasising how positive carry is identified, measured and monitored in 2025 market conditions.

Definition

Positive carry is the condition where an asset’s income or return exceeds the cost of financing or holding that position.

• The sentence above is the core technical definition required for quick reference.
• This definition is deliberately concise for use in glossaries and trading manuals.
• It is applicable across FX, bonds, commodities and leveraged real estate.

Examples of the definition in practice can be rendered as quick checks for traders and risk managers. For instance, when a trader borrows at a short-term rate to hold a high-yielding bond, the comparison between bond yield and funding rate produces a simple arithmetic check. That check is often institutionalised in pre-trade systems used by banks and fund managers such as Goldman Sachs and J.P. Morgan. The clear, one-sentence nature of this definition makes it suitable for labels on dashboards that feed into margin engines and position monitoring tools. This sentence serves as an operational tag in electronic trading systems and a compliance checkpoint on marginable positions. Key insight: the definition is intentionally compact to serve as a gating condition in trading workflows.

What is Positive carry?

Positive carry describes a structural relationship in which an investor earns net income from holding an asset after accounting for the financing cost, fees, or other carrying charges. In the futures and derivatives context, that means the expected return from the underlying exposure—coupon payments on bonds, interest rate differentials in currency pairs, or rental income in property—exceeds the cost of capital needed to maintain the position. This is a mechanistic, arithmetic observation rather than a forecast: it quantifies the immediate advantage of the placement of capital under prevailing market prices and rates.

In the futures market specifically, positive carry often manifests through cash-and-carry arbitrage, carry trades using currency forwards, or yield capture strategies where margining and collateral economics are central. Market participants examine contract specifications—delivery months, settlement method (cash vs physical), and initial and variation margin—to determine whether holding a futures position will produce a net income after funding. For instance, an institutional trader at PIMCO will compare the coupon yield of a cash bond to the repo or secured financing rate when deciding whether to implement a long futures/short cash basis trade.

• Carry arises from income streams (coupon, rent, dividend) or rate differentials (FX interest rates).
• Costs include funding rate, margin requirements, storage/insurance for physical assets, and transaction fees.
• Uniqueness: carry is a snapshot metric but becomes dynamic under changing rates or volatility.

Practically, quant teams translate the concept into per-day carry rates that feed into P&L attribution. For dealers and asset managers—whether BlackRock sizing ETF holdings or Vanguard managing fixed-income funds—positive carry informs decisions on leverage overlays and duration positioning. When carry is positive and stable, it can justify extended holding periods. When volatile, it triggers hedging or position reduction. Key insight: positive carry is an operational lens used by treasury desks and portfolio managers to align funding, collateral and asset selection.

Key Features of Positive carry

Positive carry has identifiable characteristics that determine how it is exploited and managed in traded markets. These features are structural and measurable, and they inform the contractual and risk-management details of positions across futures and cash markets. Traders and risk officers should treat carry as a multidimensional metric that integrates yield, volatility, liquidity, and funding mechanics.

• Yield differential driven: Carry is fundamentally the gap between asset income and financing cost; in FX carry trades, that is the interest rate spread between two currencies.
• Time-dependent: Carry accumulates over time; daily or monthly carry accruals feed into mark-to-market and realized P&L.
• Funding-sensitive: Changes in repo, SOFR, or overnight interbank rates can flip a positive carry into negative.
• Margin interaction: Futures margin amplifies effects—variation margin and initial margin determine effective financing cost.
• Liquidity and roll cost: For futures, the cost to roll positions across expiries (contango vs backwardation) alters net carry.
• Credit and counterparty risk: Secured vs unsecured funding affects true carrying cost for large institutions like Citigroup or State Street.
• Regulatory and operational constraints: Capital charges, haircuts on collateral, and securities lending rules shape implementable carry strategies.

Operational example: a fund uses repo financing to hold a portfolio of corporate bonds while simultaneously hedging interest rate exposure with short futures. The effective carry equals the coupon yield minus the repo rate and the net cost of the futures hedge (including margin). Large custodians and asset managers incorporate these mechanics into automated cash management systems; for instance, Fidelity Investments and Charles Schwab model net-of-funding returns for client portfolios.

Risk teams monitor scenario analysis where increases in funding rates or spikes in volatility erode carry. Because carry is sensitive to funding term and collateral, many institutions maintain a funding ladder and diversified counterparties to stabilise carrying costs. Key insight: positive carry’s features are measurable levers that desks manage continuously to preserve the net-income advantage.

How Positive carry Works — mechanics, examples and settlement

Positive carry operates through a simple arithmetic relation embedded in trading mechanics: income from the position minus financing and carry costs equals the carry. In practice, implementation varies by asset class. For FX carry trades, a trader borrows in a low-yield currency and invests in a high-yield currency, pocketing the interest differential while managing exchange-rate risk with forwards or options. In fixed-income, positive carry arises when coupon yield exceeds the cost of repo or secured borrowing; traders can use futures to synthetically obtain bond exposure while economising on funding.

• Underlying assets: currencies, government and corporate bonds, commodities with storage costs, and income-producing real estate.
• Contract specifications: futures expiry, delivery method, and margin schedule determine carry per contract.
• Margin requirements: initial and variation margin dictate effective leverage and can magnify losses if funding shocks occur.
• Settlement method: cash-settled futures change roll and collateral dynamics versus physical delivery.

Short example: borrowing Japanese yen at a near-zero rate to buy Australian dollars that yield 4% produces roughly a 4% annualised carry before accounting for FX movements and transaction costs. In a futures context, the same exposure can be constructed via currency futures with associated margin. Another example: a leveraged investment fund purchases corporate bonds yielding 5% funded via repo at 2%, yielding a 3% carry; hedging interest rate exposure with futures adds a marginal cost that reduces net carry.

Key operational notes: margining in futures means that although an investor achieves a positive carry, mark-to-market volatility may require intraday or overnight funding adjustments. In 2025’s market environment, with central banks calibrating rate paths, institutions such as BlackRock and Vanguard routinely model carry under multiple rate scenarios. Settlement conventions matter: futures that are cash-settled and trade in deep liquidity pairs often have lower roll cost, preserving carry; physically settled contracts add operational costs that can erode it.

Finally, monitoring tools track realized vs expected carry, feeding into P&L attribution and capital allocation. Firms like Morgan Stanley and Goldman Sachs use internal calculators that convert overnight carry accruals into projected quarterly contributions. Key insight: carry is straightforward to compute but operationally nuanced—funding, margins and settlement mechanics determine whether the theoretical carry translates into realised income.

Main Uses of Positive carry and Market impact

Positive carry is used across three primary investment purposes: speculation, hedging and arbitrage. Each use-case leverages the net-income property of carry but differs in time horizon, leverage and risk controls. Large institutions and sophisticated traders apply carry strategies as a predictable revenue component within diversified portfolios.

Speculation

• Carry trades are held to earn the interest differential, often with leverage to amplify returns.
• Funds deploy carry as a yield enhancement overlay, increasing expected returns but accepting currency, rate or credit risks.

Speculative use relies on stable economic conditions. For example, an asset manager might run a currency carry book long high-yield currencies funded by low-yield funding currencies to augment returns. Notable hedge funds and banks periodically expand such books when volatility is low and unwind quickly on risk-off episodes.

Hedging

• Carry can offset the cost of hedging exposures—for instance, receiving carry on a collateralized asset while hedging price risk with futures.
• Institutional treasury desks use carry to reduce net financing cost over hedged positions.

When a corporate treasurer structures a cross-currency hedge, positive carry can reduce the net hedging cost. Similarly, bond funds may use carry to finance duration hedges, where coupon income helps pay for swap payments.

Arbitrage

• Cash-and-carry and convergence arbitrage exploit mispricing between spot and futures to lock in carry profits.
• Arbitrage strategies rely on execution and funding certainty; large banks like Citigroup and State Street provide the plumbing for such trades.

Classic arbitrage: buy the physical commodity or bond and sell futures when the basis implies forward pricing that yields a positive carry after storage and financing. Traders monitor calendar spreads and roll yields to determine whether carrying the position produces arbitrage profit.

Market impact: positive carry strategies influence liquidity, price discovery and volatility. When many market participants pursue similar carry trades, capital flows can drive asset prices—e.g., high demand for high-yielding currencies can appreciate those currencies, compressing the carry. Conversely, a sudden unwind of carry books amplifies volatility as leveraged holders are forced to cover positions. Institutional players including PIMCO, BlackRock and major banks coordinate funding across desks to avoid destabilising liquidity runs.

Regulatory changes, such as collateral haircut adjustments or leverage ratio changes, also shift the economics of carry and can make previously profitable trades unattractive. In 2025, monitoring of these macro-regulatory signals has become standard for carry strategy allocation across multi-asset portfolios. Key insight: carry can be a steady source of income but its systemic effects on markets are tied to funding structure and concentration of positions.

Benefits of Positive carry

• Enhanced yields: Positive carry provides a straightforward way to increase portfolio yield above risk-free or base funding rates.
• Leverage efficiency: Properly margined futures and repo financing allow capital-efficient exposure to carry opportunities.
• Portfolio diversification: Carry returns often have different drivers from equity returns, benefiting multi-asset portfolios.
• Predictable income component: In stable markets, carry accruals are relatively steady and can support cash flow planning.

Institutional adopters use carry to fund fee structures or offset management costs. For instance, cash balances swept into high-yield short-term instruments by custodians like State Street produce carry that reduces net operating drag. Fund managers also use carry overlays to cover the cost of option hedges or insurance without liquidating core holdings. Key insight: benefits materialise when funding is predictable and market liquidity supports position maintenance.

Risks of Positive carry

• Amplified losses: Leverage magnifies adverse price moves, turning carry gains into larger losses.
• Funding risk and margin calls: A spike in funding rates or a margin call can rapidly convert positive into negative carry.
• Currency and basis risk: FX volatility and adverse basis moves can erode carry quickly.
• Concentration and crowding: Market-wide carry crowds cause correlation breakdowns during stress.
• Counterparty and operational risk: Reliance on repo counterparties or prime brokers introduces counterparty exposure.

Risk management frameworks at large organisations like Goldman Sachs, J.P. Morgan and Citigroup typically impose stress tests that simulate funding shocks, sudden rate moves, and rolling liquidity squeezes. Those simulations determine maximum allowable leverage and set stop-loss thresholds. Key insight: the principal risks of carry strategies are foreseeable and manageable—but they require disciplined funding and contingency planning.

Brief History of Positive carry

Positive carry as a practical trading concept emerged with modern interbank markets and the expansion of global capital mobility in the late 20th century. Currency carry trades grew in prominence during periods of divergent monetary policies, notably in the 1990s and again in the 2000s, as electronic execution and cheap leverage became available. Institutionalisation by major asset managers and banks formalised carry strategies into overlays and structured products by the 2010s.

• Adoption accelerated with advances in repo markets and derivatives clearing.
• Regulatory shifts after 2008 and the subsequent changes to collateral rules influenced how carry trades are financed.

Key insight: positive carry has evolved from opportunistic trades into a staple of institutional cash and overlay management, shaped by funding markets and regulatory environments.

FAQ

How is positive carry measured on a daily basis?
Daily carry is annualised from the income minus financing costs divided by position value, adjusted for day count; margin effects are converted into an effective funding rate.

Can positive carry persist during periods of rising interest rates?
Yes—if asset yields increase faster than funding rates or if the spread widens; however, rising rates often increase funding costs, so persistent positive carry depends on relative movements.

Are futures useful to capture carry?
Futures can deliver efficient exposure and reduce capital usage, but roll costs and margin requirements must be included in the net carry calculation.

Which institutions commonly execute carry strategies?
Large asset managers and banks—such as BlackRock, PIMCO, J.P. Morgan and Goldman Sachs—deploy carry as overlays, liquidity management tools, or dedicated strategies.

When does positive carry turn negative?
When financing costs, roll costs, or losses from underlying asset moves exceed the income generated; abrupt funding shocks or rapid adverse price moves are common triggers.
