Intermarket Analysis: Stocks, Bonds, Commodities and Currencies

Introduction

No market moves in a vacuum. A rally in crude oil can ripple through airline stocks and energy company margins. Rising bond yields can pull capital away from equities. A weakening currency can boost exporters while squeezing companies that rely on imported inputs. These relationships aren’t coincidences — they’re the subject of intermarket analysis, a framework built on the idea that stocks, bonds, commodities, and currencies are deeply interconnected, and that understanding those connections adds a layer of context no single-market chart can provide on its own.

This article explains the core relationships intermarket analysis examines, how they typically behave, and how to apply this broader lens alongside traditional single-market technical analysis.

What Is Intermarket Analysis?

Intermarket analysis is the study of the relationships between different asset classes — typically stocks, bonds, commodities, and currencies — to understand how movement in one market can influence, confirm, or contradict movement in another.

Rather than analyzing a stock or index purely in isolation, intermarket analysis treats financial markets as an interconnected system, where shifts in one asset class often have knock-on effects across others, driven by the flow of capital, changing interest rate expectations, inflation dynamics, and shifting economic conditions.

The core premise is straightforward: markets don’t operate independently, and analyzing only one asset class while ignoring the others can mean missing meaningful context behind a given move.

The Four Core Asset Classes

Intermarket analysis is traditionally built around the relationships between four major asset classes:

• Stocks — represent ownership in companies and are generally sensitive to economic growth expectations, corporate earnings, and interest rates.
• Bonds — represent debt and interest payments, and are highly sensitive to interest rate expectations and inflation.
• Commodities — represent raw materials and physical goods, sensitive to supply and demand dynamics, inflation, and economic growth.
• Currencies — represent relative value between economies, sensitive to interest rate differentials, trade flows, and capital flows between countries.

Because all four asset classes respond to overlapping macroeconomic forces — interest rates, inflation, growth expectations, and capital flows — they frequently move in relationship to one another, even when the specific mechanism driving that relationship shifts over time.

Stocks and Bonds

The relationship between stocks and bonds is one of the most closely watched in intermarket analysis, primarily through the lens of interest rates and bond yields.

• Rising bond yields (falling bond prices) generally reflect expectations of stronger economic growth, higher inflation, or tighter monetary policy. Rising yields can make bonds more attractive relative to stocks and can increase borrowing costs for companies, which has historically created headwinds for equities — particularly for growth-oriented or highly leveraged companies more sensitive to financing costs.
• Falling bond yields (rising bond prices) often reflect expectations of slower growth, lower inflation, or looser monetary policy, and can be supportive for equities by reducing the discount rate applied to future earnings and lowering borrowing costs.

This relationship is not fixed or mechanical — the stock-bond relationship has shifted over different historical periods depending on the dominant macroeconomic driver (growth-driven versus inflation-driven environments), which is why intermarket analysts pay close attention to why yields are moving, not just the direction of the move itself.

Stocks and Commodities

The relationship between stocks and commodities is more nuanced, and depends significantly on which commodity is being examined and the broader economic context.

• Rising commodity prices, particularly for industrial commodities, can sometimes reflect strengthening economic demand — potentially supportive for cyclical stocks and sectors tied to industrial activity.
• Sharply rising commodity prices, especially in energy, can also act as a cost headwind for many businesses and consumers, potentially becoming a drag on broader economic growth and equity markets if the increase is large or sustained.
• Falling commodity prices can reflect weakening demand and slowing growth expectations, which can weigh on cyclical and commodity-linked sectors even as it may benefit sectors sensitive to input costs.

This dual nature — commodities as both an economic growth signal and a potential cost headwind — is why the stock-commodity relationship requires more careful, context-dependent interpretation than the more direct stock-bond relationship.

Bonds and Commodities

Bonds and commodities are often examined together through the lens of inflation expectations.

• Rising commodity prices, particularly sustained increases across a broad basket of commodities, can signal building inflationary pressure, which tends to push bond yields higher (and bond prices lower) as investors demand greater compensation for holding fixed-income assets in an inflationary environment.
• Falling commodity prices can signal easing inflationary pressure, which can support lower bond yields and higher bond prices.

This inflation-driven relationship between commodities and bonds is one of the more consistent intermarket relationships, since both asset classes are directly sensitive to the same underlying inflation dynamics, even though they express that sensitivity in different ways.

Currencies and Commodities

Currency movements — particularly in major reserve currencies — often show a notable relationship with commodity prices, since many globally traded commodities are priced in a specific currency.

• A weaker currency (in which commodities are typically priced) can make those commodities cheaper for buyers using other currencies, potentially supporting demand and commodity prices.
• A stronger currency can have the opposite effect, making commodities priced in that currency relatively more expensive for foreign buyers, which can act as a headwind for commodity prices.

This relationship is one of the more structurally persistent intermarket dynamics, since it’s rooted in the mechanics of how globally traded commodities are priced and transacted internationally.

Currencies and Stocks

The relationship between a country’s currency and its stock market is more variable and depends heavily on the specific economy and the composition of its stock market.

• For economies with significant export-oriented industries, a weaker domestic currency can make exports more competitive internationally, potentially benefiting export-heavy companies and their stock prices.
• For economies more dependent on imports or foreign capital inflows, a weaker currency can act as a headwind, increasing input costs or making the market less attractive to foreign investors.
• Currency strength can also reflect broader confidence in an economy’s growth prospects and monetary policy, which itself can carry information relevant to equity market sentiment.

Because this relationship depends heavily on the specific structure of a given economy and its market composition, it requires more country-specific context than some of the other intermarket relationships.

The Business Cycle and Intermarket Rotation

A central concept in intermarket analysis is that different asset classes tend to lead or lag one another at different phases of the broader economic and business cycle.

A commonly referenced general sequence (though real-world cycles rarely follow it perfectly) suggests:

1. Bonds tend to lead, with yields often beginning to fall (bond prices rising) as economic growth starts to slow, anticipating future central bank easing.
2. Stocks often follow, as falling yields and eventual policy easing support equity valuations, even before the broader economy has clearly bottomed.
3. Commodities tend to lag, since commodity demand is typically more directly tied to actual realized economic activity, which usually recovers after financial markets have already begun anticipating the recovery.
4. Currencies respond throughout, reflecting shifting interest rate differentials and capital flows as the cycle progresses.

This general sequence is a simplified framework rather than a precise, repeatable formula — actual market behavior in any given cycle can deviate significantly depending on the specific circumstances driving that cycle (for example, a cycle driven primarily by a supply shock may behave quite differently from one driven by a demand slowdown).

Using Intermarket Analysis for Confirmation

One of the most practical applications of intermarket analysis is using relationships across asset classes as a confirmation or contradiction check on a single-market technical view.

For example:

• A bullish technical setup on a stock index that coincides with falling bond yields and stable-to-firm commodity prices may be viewed as receiving broader macro support for the setup.
• A bullish technical setup on a stock index that coincides with sharply rising bond yields and weakening currency conditions may warrant additional caution, since the broader intermarket backdrop is showing potential headwinds not visible on the equity chart alone.

This doesn’t mean intermarket signals should override a well-formed technical view — rather, they add an additional, independent layer of context that can either reinforce or raise questions about a purely single-market analysis.

Sector-Specific Intermarket Relationships

Certain equity sectors have historically shown particularly strong intermarket relationships with specific other asset classes, making sector-level intermarket analysis a useful refinement of the broader framework:

• Energy sector stocks often show a relationship with crude oil prices, given the direct link between oil prices and energy company revenues.
• Financial sector stocks, particularly banks, often show sensitivity to bond yields and the shape of the yield curve, since bank profitability is influenced by interest rate spreads.
• Materials and industrial sector stocks often show relationships with broader industrial commodity prices, given their direct exposure to raw material costs and demand.
• Export-heavy sectors often show sensitivity to currency movements, given the direct impact of currency strength on international competitiveness.

Applying intermarket analysis at the sector level, rather than only at the broad index level, can sometimes surface more directly relevant relationships for a specific investment decision.

Common Intermarket Analysis Mistakes

1. Treating intermarket relationships as fixed and mechanical. These relationships can shift over different macroeconomic regimes; a relationship that held reliably in one period may weaken or even invert in another.
2. Ignoring the underlying driver behind a move. The same directional move in a given asset class (for example, rising commodity prices) can have different implications depending on whether it’s being driven by strengthening demand or a supply disruption.
3. Overgeneralizing sector-specific relationships to the whole market. A relationship that holds strongly for one sector (such as energy stocks and oil prices) may not apply meaningfully to the broader market index.
4. Using intermarket analysis as a standalone timing tool. Intermarket relationships are generally more useful as broader context and confirmation than as a precise trading trigger on their own.
5. Ignoring country-specific context in currency relationships. Currency-equity relationships depend heavily on the specific structure of an economy, which means generalizing from one country’s experience to another can be misleading.

Building an Intermarket Analysis Routine

Step 1: Establish the trend in each core asset class. Assess the prevailing direction in equities, bonds (via yields), commodities, and relevant currencies.

Step 2: Identify the likely underlying driver. Consider whether recent moves appear to be driven primarily by growth expectations, inflation dynamics, monetary policy, or another factor.

Step 3: Check for confirmation or contradiction across asset classes. Assess whether the relationships between asset classes appear consistent with historical patterns, or whether something unusual is occurring.

Step 4: Apply relevant relationships at the sector level. Consider sector-specific intermarket relationships relevant to the specific stocks or sectors being analyzed.

Step 5: Combine with single-market technical analysis. Use intermarket context to support or question a technical view on a specific stock, sector, or index, rather than replacing that analysis entirely.

Step 6: Reassess periodically. Recognize that intermarket relationships can shift over time, and periodically revisit whether previously reliable relationships still appear to be holding.

Intermarket Analysis Example

An equity index technical setup shows a confirmed bullish break of structure, with the index moving above a significant prior resistance level. Examining the broader intermarket backdrop at the same time shows bond yields declining steadily over the preceding weeks, commodity prices stable, and the domestic currency holding in a relatively narrow range.

This combination — a bullish equity structural break occurring alongside falling yields and a stable broader macro backdrop — is generally viewed as a supportive intermarket environment for the equity move, reinforcing rather than contradicting the technical signal on the index itself. Had bond yields instead been spiking sharply higher at the same time, the intermarket backdrop would have warranted additional caution despite the same bullish technical structure on the index.

Intermarket Analysis for NEPSE Investors

Applying intermarket analysis to the Nepal Stock Exchange (NEPSE) requires adapting the general framework to Nepal’s specific economic structure and the assets most relevant to it.

• Interest rates and bank lending conditions are particularly relevant to NEPSE, given the significant weighting of banking and financial sector companies within the exchange — shifts in domestic interest rates and monetary policy can have an outsized effect on the broader index.
• Remittance flows and the Nepali rupee carry particular relevance given Nepal’s economic reliance on remittance income, which can influence broader liquidity conditions relevant to the stock market.
• Global commodity prices, particularly for imported fuel and other key inputs, can affect broader economic conditions and corporate costs relevant to NEPSE-listed companies, even though Nepal is not a major commodity producer itself.
• As with applying any broad framework to a specific market, NEPSE-focused intermarket analysis should account for the exchange’s particular sector composition and Nepal’s specific economic structure, rather than directly importing relationships observed in larger, more diversified economies.

Frequently Asked Questions

What is intermarket analysis?
Intermarket analysis is the study of relationships between different asset classes — typically stocks, bonds, commodities, and currencies — to understand how movement in one market can influence or provide context for movement in another.

How are stocks and bonds related in intermarket analysis?
Rising bond yields generally reflect expectations of stronger growth or higher inflation and can create headwinds for equities, while falling yields often support equity valuations, though this relationship can shift depending on the broader macroeconomic environment.

Why do commodities matter to bond markets?
Commodity prices, particularly when rising broadly and persistently, can signal building inflationary pressure, which tends to push bond yields higher as investors demand greater compensation for inflation risk.

How does currency strength affect commodity prices?
Since many globally traded commodities are priced in a specific currency, a weaker version of that currency can make commodities cheaper for foreign buyers, potentially supporting demand and prices, while a stronger currency can have the opposite effect.

Do intermarket relationships always hold true?
No. Intermarket relationships can shift depending on the broader macroeconomic regime and the underlying driver of a given move; they are generally treated as useful context rather than fixed, mechanical rules.

Is intermarket analysis useful for individual stock selection?
Yes, particularly when applied at the sector level, since certain sectors (such as energy, financials, and materials) often show more direct relationships with specific other asset classes than the broader market does.

Should intermarket analysis replace single-market technical analysis?
No. Intermarket analysis is generally used as an additional layer of context to confirm or question a technical view derived from single-market analysis, rather than as a replacement for it.

Key Takeaways

Intermarket analysis broadens the analytical lens beyond a single chart, recognizing that stocks, bonds, commodities, and currencies are deeply interconnected. Core concepts include:

1. Stocks and bonds are connected primarily through interest rates and growth expectations
2. Commodities relate to both economic growth signals and inflation dynamics
3. Currencies and commodities are linked through global pricing mechanics
4. Different asset classes tend to lead or lag at different phases of the business cycle
5. Intermarket relationships can shift over time and are not fixed, mechanical rules
6. Sector-specific intermarket relationships often provide more direct relevance than broad index-level relationships
7. Intermarket analysis works best as confirmation or context for single-market technical analysis, not as a replacement

Conclusion

No stock, sector, or index exists in isolation from the broader financial system around it. Intermarket analysis provides a framework for understanding how bonds, commodities, and currencies interact with — and often help explain — movements in equity markets, adding a layer of macro-level context that single-market technical analysis alone cannot capture.

Used alongside market structure, breadth, and relative strength analysis, an awareness of these cross-asset relationships helps investors see not just what a specific stock or index is doing, but the broader financial backdrop that may be driving it.
