Want to understand how fixed income and commodities interact in financial markets? Here’s the key takeaway: their relationship isn’t fixed – it changes based on economic conditions. For traders in Singapore, this knowledge is crucial for managing risk and seizing opportunities.

Why does this matter?

• Fixed income (like bonds) and commodities (like oil or gold) often show negative correlations. For instance, during inflation, commodity prices rise, while bond prices fall.
• These correlations can shift due to factors like economic cycles, central bank policies, and global events.

What you’ll learn in this guide:

• How Singapore’s unique market environment (e.g., the SGD, SGX-traded instruments) influences these relationships.
• Tools for measuring correlations, like rolling correlations and real-time data.
• Practical trading strategies, including portfolio diversification and hedging.

Historical and Current Correlation Trends

To navigate the complexities of trading, it’s crucial to understand how fixed income and commodity assets interact over time. These relationships are far from fixed; they shift based on economic cycles, policy changes, and overall market sentiment.

Correlation Changes During Market Cycles

Economic phases have always played a significant role in shaping the relationship between bonds and commodities. For instance, during periods of inflation, commodity prices often climb while bonds tend to lose value, leading to a negative correlation. On the other hand, in deflationary or recessionary periods, when investors flock to safer assets, bonds and commodities may move together, resulting in a positive correlation. In times of strong economic growth, these dynamics can become more complex. Gains in productivity might temper these shifts, while aggressive monetary policies can amplify volatility, making correlations harder to predict.

The 2008 financial crisis was a pivotal moment, marking a departure from traditional patterns and ushering in a period of heightened market volatility. Since then, the need for more nuanced and tailored analysis has become increasingly apparent.

Recent Changes in Correlations (2020–2025)

The period from 2020 to 2025 has brought notable changes to the bond-commodity relationship. A combination of aggressive monetary policies and disruptions in global supply chains has reshaped these dynamics. For example, during the early stages of the COVID-19 pandemic, liquidity measures introduced by central banks significantly impacted markets, pushing correlations toward more negative territory. As monetary policies shifted to address evolving economic conditions, these relationships grew even more complex and unpredictable.

These recent trends underscore the importance of staying adaptable. Traders now need to account not only for global developments but also for localised factors, particularly in Singapore’s unique market environment.

Singapore-Specific Factors

While global trends set the broader stage, local factors in Singapore introduce additional layers of complexity. Regulatory policies and domestic demand patterns contribute to correlation shifts that may differ from global norms. For instance, the Monetary Authority of Singapore (MAS) influences currency-sensitive assets, with fluctuations in the Singapore dollar often impacting the volatility of commodities priced in foreign currencies.

Singapore’s role as a regional hub for trading and refining further shapes its market dynamics. Local supply and demand forces can create unique correlation patterns, distinct from global trends. The Singapore Exchange (SGX) also plays a critical role in price discovery, particularly during times of regional economic uncertainty. Additionally, Singapore’s integration within ASEAN and its trade agreements strengthen ties with neighbouring markets, further influencing these relationships.

Economic Drivers That Affect Correlations

To grasp the interplay between fixed income and commodity correlations, it’s essential to dive into the economic forces behind them.

Macroeconomic Factors

Central bank policies play a key role in shaping bond-commodity correlations. In Singapore, the Monetary Authority of Singapore (MAS) uses an exchange rate-centred monetary policy to influence local market conditions. Adjustments to the Singapore dollar’s nominal effective exchange rate directly impact the cost of imported commodities and the valuation of bonds.

For instance, when the US Federal Reserve raises interest rates, the US dollar strengthens, which tends to push commodity prices lower. At the same time, this makes bonds more appealing, amplifying their negative correlation. Inflation expectations add another layer of complexity. Singapore’s core inflation – excluding costs like accommodation and private transport – affects how local investors position themselves in both fixed income and commodity markets. Rising inflation typically drives bond prices down as investors demand higher yields to offset reduced purchasing power, while commodities often gain from inflationary pressures.

Currency movements, especially the USD/SGD exchange rate, further complicate the picture. Since Singapore relies heavily on commodity imports, fluctuations in exchange rates affect the local cost of these commodities. A stronger Singapore dollar, for example, can lower the price of imported goods while also influencing the relative appeal of Singapore government securities compared to US Treasuries.

These macroeconomic factors create the foundation for market-specific events that influence correlation patterns even further.

Market-Specific Drivers

Geopolitical events and economic cycles often shift correlation dynamics. The 2022 seizure of Russian central bank assets, for example, led to a major shift in global reserve management. In response, central banks worldwide began diversifying away from dollar-denominated assets. Over the past three years, global central banks have purchased over 1,000 metric tonnes of gold annually – more than double the 2010–2021 average of 473 metric tonnes. This surge in gold demand has reshaped the relationship between precious metals and government bonds.

During stagflationary periods, when rising prices coincide with slowing economic growth, both bonds and commodities may move in the same direction. Conversely, in periods of economic growth, negative correlations often emerge. Strong economic activity fuels demand for commodities, while expectations of higher interest rates put downward pressure on bond prices.

Short-term disruptions like these are layered onto broader, long-term trends that continue to evolve and reshape these relationships.

Long-Term Market Trends

Structural shifts such as deglobalisation and supply chain restructuring are driving up commodity prices while slowing economic output. This dual effect complicates correlation patterns, as rising inflation expectations push bond yields higher, potentially resulting in a positive correlation between fixed income and commodities.

The global energy transition and the rapid pace of digitisation are also reshaping demand. Industrial metals like copper are seeing increased demand, driven by these trends. Singapore’s role as a regional data centre hub highlights the importance of accounting for these structural changes when analysing correlation patterns.

Efforts to reduce dependence on the US dollar, often referred to as “de-dollarisation”, are also impacting traditional safe-haven assets. Trade policies and geopolitical tensions have reduced foreign demand for US debt, leading to higher yields and weakening the dollar’s status as a safe haven. This shift means US Treasuries may no longer provide the same level of protection during periods of market stress, altering how correlations behave during crises.

These long-term trends suggest that traditional assumptions about correlations may no longer apply in many market scenarios. For instance, supply chain disruptions can lead to higher inflation, and in such conditions, investors may see positive correlations between stocks and bonds, with both asset classes potentially declining at the same time.

The evolving nature of these drivers requires traders to constantly reassess their strategies. By understanding how macroeconomic policies, market events, and structural changes interact, traders can better navigate the intricate web of relationships between fixed income and commodity markets. This nuanced approach is key to adapting to changing correlation patterns effectively.

Methods for Analysing Correlations

Understanding the economic forces behind fixed income-commodity correlations is just one piece of the puzzle. The other lies in using systematic methods to measure and analyse these relationships effectively. With the right techniques, market insights can be turned into actionable strategies.

Techniques for Measuring Correlations

One popular approach is rolling correlations, which calculate coefficients over moving time windows. This method helps capture how asset relationships evolve over time. For traders in Singapore, applying rolling correlations to local government securities and key commodity benchmarks can uncover market shifts and emerging trends.

Another powerful tool is Principal Component Analysis (PCA). PCA simplifies complex datasets by identifying the fundamental drivers behind asset movements. For instance, it can reveal whether factors like interest rate expectations or inflation concerns are driving correlations between fixed income and commodity markets.

Regime-switching models take things further by detecting shifts in market conditions and adjusting correlation estimates accordingly. These models are especially useful for identifying how correlations behave differently during times of market optimism versus periods of uncertainty.

Together, these methods lay the groundwork for real-time analysis.

Using Real-Time Data for Analysis

Real-time data transforms correlation analysis from a static, historical exercise into a dynamic tool. Access to live pricing – such as data from the Singapore Exchange on local government securities and commodity derivatives – allows traders to track correlation shifts as they happen. Many advanced trading platforms even let users compute real-time correlations and overlay this data on price charts, making it easier to spot deviations from historical patterns.

Choosing the right data frequency, whether daily or intraday, is crucial. While higher-frequency data provides more detail, it can also introduce noise. The key is to strike a balance, calibrating the interval based on the trading strategy and the characteristics of the assets being analysed.

One challenge with real-time analysis is distinguishing genuine shifts in correlations from temporary market noise. For example, a sudden change in bond-commodity correlation during a market open might indicate either a fundamental shift or a brief liquidity imbalance. Analysing data across multiple timeframes can help separate short-term noise from meaningful changes.

The next step is integrating these insights into trading systems.

Adding Correlation Analysis to Trading Systems

Once measurement techniques and real-time insights are in place, the focus shifts to systematic integration to enhance trading performance. For example, Collin Seow Trading Academy emphasises the use of rule-based correlation filters to minimise emotional decision-making.

Dynamic position sizing is another effective strategy. By adjusting position sizes as asset correlations fluctuate, traders can maintain a balanced risk profile. For instance, when correlation measures hit certain thresholds, a systematic setup might automatically scale positions up or down to manage portfolio risk.

Correlation-based entry filters add another layer of precision. By requiring specific correlation criteria to be met before executing trades, traders can align new positions with broader market trends, increasing the likelihood of success.

Many trading programmes follow a structured, multi-phase approach. First, they identify which correlations are most relevant for a given market. Next, they code these insights into trading algorithms. Finally, they monitor and adjust the system based on how correlation changes impact overall performance.

Risk management is central to any correlation-based strategy. Automated platforms can be programmed to adjust positions if correlation metrics shift significantly, protecting capital during volatile conditions. This is especially beneficial for Singapore traders who need to monitor both local and global markets in real time.

Lastly, rigorous backtesting across various market conditions is essential. A strong trading system should perform consistently, whether the market is trending, ranging, or experiencing rapid shifts in correlation. This disciplined, data-driven approach ensures effective risk management and a well-rounded portfolio strategy.

Trading Strategies Using Correlation Data

Building on the earlier discussion of systematic correlation analysis, let’s explore how to put this knowledge into action. For traders, especially those in Singapore with access to both local government securities and international commodity markets, disciplined execution and well-defined risk parameters are essential when crafting strategies based on fixed income-commodity correlations.

Portfolio Diversification and Hedging

Negative correlations can play a pivotal role in stabilising portfolios. For instance, when Singapore Government Securities (SGS) bonds and commodity futures show a negative correlation, combining these assets can help reduce overall portfolio volatility. This becomes particularly useful during periods of market stress when traditional asset relationships tend to falter.

Position sizing based on correlation strength is another key tactic. If your analysis uncovers a strong negative correlation between specific bonds and commodity futures, increasing exposure to both could provide natural hedging benefits. A practical example would be using cross-asset hedging: if palm oil futures and SGS bonds demonstrate a negative relationship, a modest allocation to palm oil futures might help offset potential losses in bond positions, especially during inflationary periods.

To refine this approach, calculate hedge ratios using correlation and volatility data, and apply dynamic rebalancing. Many systematic traders routinely adjust their positions when correlation trends shift, ensuring their portfolios remain optimised for current market conditions.

This framework lays the groundwork for more tactical adjustments based on changing market dynamics.

Tactical Asset Allocation

In risk-off environments, shifting your focus from commodities to fixed income can improve risk-adjusted returns. Statistical analysis can help identify these market regimes. For example, if data suggests that bonds and commodities are moving more in sync during a risk-off phase, reducing commodity exposure in favour of more stable fixed income assets might be a prudent move.

Momentum-based correlation trading offers another layer of opportunity. Persistent trends in asset correlations can guide allocation decisions, while sector rotation within commodities – such as moving between energy and agricultural sectors – can unlock further potential. For instance, agricultural commodities often exhibit seasonal patterns that traders can leverage to make timely allocation adjustments.

Systematic approaches often rely on predefined quantitative triggers. These triggers, based on thresholds like shifts in correlation strength, serve as signals to adjust asset allocations dynamically.

Risk Management and Continuous Learning

Effective risk management and continuous refinement of strategies are the backbone of correlation-based trading.

Set position limits when correlations spike. High correlations between fixed income and commodity positions can increase risk concentration, making aggregate exposure limits essential to avoid unintended risks.

Stop-loss mechanisms tied to changes in historical correlation patterns add another layer of protection. For example, if a previously negative correlation flips and remains positive, it may signal the need to reassess position sizes.

Continuous learning is equally important. Resources like the Collin Seow Trading Academy emphasise the value of understanding and adapting to evolving market relationships. Their systematic trading methods incorporate correlation analysis as a core risk management tool.

Stress testing correlation assumptions can prevent overreliance on historical patterns. Experienced traders often simulate how their strategies might perform during extreme market disruptions, allowing them to identify vulnerabilities and adjust accordingly.

Documenting and reviewing trading decisions is another crucial practice. Detailed records of trades, including the rationale behind them, correlation metrics at the time, and subsequent performance, can help traders refine their strategies over time.

Lastly, risk budgeting by correlation exposure can safeguard the portfolio. By assigning specific risk budgets to various correlation strategies, traders can ensure no single approach dominates the portfolio’s overall risk. Regular stress tests of these assumptions provide insights into how strategies might hold up under extreme conditions, enabling better preparation for potential downside scenarios.

Case Studies and Practical Examples

Taking a closer look at systematic correlation analysis, examples from the trading world show how historical data and thorough backtesting can help traders fine-tune their strategies. Analysing the correlations between different asset classes allows traders to spot diversification opportunities and improve risk management – especially during volatile market conditions. Let’s explore a couple of ways correlation strategies can be woven into systematic trading practices.

One approach involves leveraging systematic analysis to pinpoint investment styles with low correlation, which can significantly enhance diversification. For instance, backtesting has repeatedly shown that commodity trading advisors (CTAs) and macro funds can act as a strong buffer for portfolios, particularly in times of market stress. This knowledge empowers traders to adjust their strategies as market relationships shift over time.

For traders in Singapore, applying a systematic framework that accounts for local market specifics can be especially beneficial. For example, incorporating SGX-traded commodity derivatives alongside Singapore Government Securities into a portfolio could improve risk management and overall performance. The key lies in a disciplined evaluation of correlation model reliability and continuously refining strategies to keep pace with evolving market dynamics.
