For years, a piece of advice from a mentor about what truly drives financial markets often went unheeded. Like a child being told that vegetables are good for them, it was heard but not fully absorbed. The focus remained on the immediate: sifting through the day’s headlines or meticulously building discounted cash flow models.
A quick scan of financial news today presents a similar impression – markets are seemingly dictated by war and energy prices. Oil spikes dominate conversations, geopolitical developments are framed as pivotal turning points, and every escalation is treated as a potential market catalyst. While these events feel important and urgent, they largely miss the fundamental point.
The core lesson, often overlooked by many investors, is that while these events capture attention, they are not the ultimate drivers of asset prices over the long term. They are inputs, not the final outcomes. The single most crucial variable, underpinning every valuation, allocation decision, and portfolio result, is interest rates. The price of money dictates everything. This has always been the case and remains true today.
The Force Beneath Everything
At its heart, investing is an exercise in discounting the future. Every asset, from government bonds and growth stocks to infrastructure, is valued based on the present value of its future cash flows. The rate used for this discounting process is directly or indirectly derived from the risk-free rate.
This alone highlights the importance of interest rates. However, their influence extends far beyond this. They determine the cost of capital across the entire economy, shaping borrowing decisions for both households and businesses. They influence the relative attractiveness of riskier assets compared to holding cash. They drive currency movements through interest rate differentials and underpin global financial conditions, setting the tone for liquidity, leverage, and ultimately, risk appetite.
In essence, when expectations around interest rates shift, everything else shifts with them. This explains why markets can sometimes appear disconnected from the immediate headlines. While investors might focus on the direct cause of an event, markets are often pricing in the subsequent, or second-order, effect. The critical question is never just what has happened, but what it signifies for monetary policy.
How Markets Process Shocks
Geopolitical events and energy shocks do hold significance, but not in the way they are typically presented. Their importance stems from their impact on inflation. And inflation matters because of how it compels central banks to act. It is this central bank reaction function, rather than the event itself, that truly drives markets.
The chain of events is quite straightforward: a geopolitical shock leads to higher energy prices. These higher energy prices then feed into inflation expectations. Central banks respond by tightening monetary policy or delaying any easing measures. Consequently, interest rate expectations rise. This, in turn, leads to asset prices repricing. By the time the market reaction becomes significant, the focus has shifted from the initial event to the trajectory of interest rates.
History Offers Numerous Examples
The inflation of the 1970s is often attributed to oil shocks. However, inflationary pressures were already building before energy prices began their surge. The defining moment arrived later, when Federal Reserve Chair Paul Volcker dramatically increased interest rates, peaking at an extraordinary 20% in June 1981, to restore central bank credibility. This policy shift, not the oil price itself, fundamentally reshaped markets.
Fast forward to 2008, and a similar pattern emerges. The global financial system fractured under the weight of excessive leverage and poor credit quality. Yet, markets did not stabilise due to improved headlines. Stability was achieved when the Federal Open Market Committee slashed interest rates to near zero and provided crucial liquidity support.
The same dynamic played out in 2020. Markets experienced a sharp decline as the COVID-19 pandemic unfolded. However, the turning point came with the policy response. Rate cuts and liquidity injections restored confidence and reset the pricing of risk.
Perhaps the most illustrative example occurred in 2022. Oil prices surged, and geopolitical tensions escalated. Despite these dramatic events, the defining market move was the repricing of interest rates. Real yields climbed sharply, equity valuations compressed, credit spreads widened, and the US dollar strengthened. While oil prices peaked early in this cycle, interest rates continued to move, and markets followed suit.
Where We Stand Today
This same dynamic is currently unfolding. In the United States, the Federal Reserve has paused its rate hikes, but it has not yet signalled a pivot towards easing. The message from Chair Jerome Powell has been consistent: inflation remains a concern, and policy is likely to stay restrictive until there is greater confidence that it is under control. The projected path of interest rates suggests a gradual easing cycle, rather than a rapid decline.
In Australia, the Reserve Bank of Australia (RBA) has adopted a similarly cautious approach. The RBA has lifted the cash rate to 4.10% and indicated a readiness to act further if inflation pressures persist. Crucially, the RBA has explicitly linked recent developments in energy markets to inflation risks, and subsequently, to the future path of interest rates.
This linkage is the key insight. Central banks are not reacting directly to geopolitical conflicts. They are reacting to what these events mean for inflation, and therefore, what they signify for monetary policy. Markets are exhibiting the same behaviour.
The Real Investor Debate
When stripped down to its core, the current market environment can be distilled into a single, fundamental question:
- Where will interest rates ultimately settle, and for how long will they remain at that level?
Everything else will flow from the answer to this question.
If interest rates remain higher for an extended period, the implications are clear:
* Equity valuations will likely face ongoing pressure as discount rates stay elevated.
* Bond markets must contend with the risk that yields may not have reached their peak.
* Credit markets will become more vulnerable as refinancing costs rise.
* Currency movements will continue to reflect interest rate differentials, reinforcing global financial conditions.
Conversely, if economic growth slows and inflation recedes more rapidly than anticipated, the path opens for earlier and more aggressive interest rate cuts. In such a scenario:
* Long-duration assets become more attractive.
* Equity multiples have the potential to expand.
* Risk assets, in general, stand to benefit from more favourable financial conditions.
These represent fundamentally different economic worlds. However, the dividing line between them is not oil prices or geopolitical tensions. It is, unequivocally, the path of interest rates.
A More Productive Way to View Markets
This analysis is not to suggest that geopolitical risks or energy markets should be ignored. They are important and can, at times, dominate short-term price action. Their true significance, however, lies in how they feed into the broader macroeconomic framework, rather than in their capacity to drive markets independently over sustained periods.
For investors, the implication is straightforward. Time spent deciphering every daily headline is often less valuable than time invested in understanding how those headlines might influence central bank behaviour.
This requires a shift in focus – moving away from the immediate noise and towards the underlying mechanisms. It means paying closer attention to inflation dynamics, labour market conditions, and financial conditions. It involves observing how central banks frame risks, not just the nature of those risks themselves. And it necessitates recognising that markets are forward-looking, pricing in not what is happening today, but what it implies for tomorrow’s policy settings.
Markets may appear fixated on war and energy, but they are ultimately governed by something far more fundamental. Interest rates are the gravitational force of investing. They anchor valuations, shape investor behaviour, and determine outcomes across all asset classes. Everything else, no matter how dramatic, is secondary. So, the next time markets react to a geopolitical headline or an oil price spike, it’s worth asking a simple question:
Does this fundamentally alter the expected path of interest rates?
Because if the answer is no, it likely doesn’t matter as much as it initially seems.
