Introduction

At present, the global economy is entering a complex and delicate adjustment phase. Unlike the growth model of the past few decades, which was driven mainly by demand, the new macro environment shows the rare coexistence of three features: supply shocks, policy constraints, and investment support. Geopolitical risks, especially the ongoing turmoil in the Middle East, add a high degree of uncertainty to this landscape. This article aims to analyze how these three forces interact and to explore their deeper impact on the global economic outlook in the second half of the year.

1. Supply Shocks: Reshaping the Global Price System from the Cost Side

Disruptions on the supply side have become the most prominent structural contradiction in the global economy today. From energy and raw materials to key components, the vulnerability of supply chains has been laid bare by the overlap of the pandemic, geopolitical conflicts, and extreme weather events. As the "central nervous system" of global energy supply, any escalation in the Middle East conflict is rapidly transmitted to international oil prices. Sharp oil price swings are not just an energy-cost issue; through a chain reaction across upstream production, logistics and transportation, and downstream consumption, they broadly raise input costs across industries. This cost-push inflation is highly persistent because it does not stem from overheated demand, but from a substantive contraction in supply capacity. As a result, traditional demand-management tools often fall short in dealing with this kind of inflation and may even harm the recovery.

2. Policy Constraints: The Difficult Balance Between Inflation and Growth

In the face of persistent high inflation, the central banks of major economies have adopted aggressive monetary tightening over the past year. However, as interest rates have risen rapidly, policy room has been squeezed quickly. On the one hand, overly tight monetary policy may accelerate recession, leading to higher unemployment and exposing corporate debt risks; on the other hand, an early pivot to easing could entrench inflation expectations and trap the economy in a "wage-price spiral." This policy constraint makes macro management akin to walking a tightrope, where any slight misjudgment could trigger violent market turbulence. More concerning is that fiscal policy is also constrained by high debt levels, leaving little room for large-scale stimulus. Policymakers therefore have to make extremely cautious trade-offs between curbing inflation and sustaining growth.

3. Investment Support: A "Stabilizer" Against Downside Pressure

In a context of weak private consumption and soft foreign trade exports, investment—especially infrastructure and industrial-upgrade investment—has become a key tool for supporting growth in many economies. Governments are using fiscal subsidies, tax incentives, and policy-oriented financial instruments to channel capital into strategic areas such as new energy, digital infrastructure, and advanced manufacturing. This investment-support strategy has a dual meaning: in the short term, it stimulates upstream and downstream demand and creates jobs through the multiplier effect; in the long term, it aims to optimize the economic structure and improve total factor productivity. However, investment support also carries risks of resource misallocation and debt accumulation, and it must move in step with market-oriented reforms to build sustainable internal momentum.

4. Stagflation Is Emerging but Not Yet Out of Control: The Core View for the Second Half of the Year

Taking the three factors above together, global economic growth in the second half of the year is expected to enter a phase where stagflation is visible but not yet out of control. Growth momentum will slow significantly, while inflation will remain elevated under supply pressures and the lagged transmission of policy, though the likelihood of a large-scale financial crisis is low. The biggest variable remains oil-price disruptions caused by the Middle East situation—if conflict intensifies and disrupts crude oil supply, the depth and breadth of stagflation will deteriorate rapidly; conversely, if geopolitical risks ease, lower oil prices will give central banks a valuable breathing space. In addition, whether investment-support policies in China and other major economies can effectively offset weakening external demand will also be a key variable shaping the global growth map.

Conclusion

Supply shocks, policy constraints, and investment support are jointly shaping a new global economic cycle characterized by low growth, high costs, and high uncertainty. For companies and investors, it is necessary to abandon the old linear mindset of "low inflation, high growth" and instead build a more resilient risk-management framework. For policymakers, the task is to go beyond short-term symptom relief and, through coordinated supply-side reform and structural investment, fundamentally repair the balance of the global economy. Stagflation has emerged, but the risks remain manageable; the key lies in whether all parties can meet this unprecedented challenge with wisdom and patience.
