A New Phase in the Interest Rate Cycle: Rethinking Monetary Policy Divergence in the US, UK, and Europe and Global Asset Allocation

A New Phase of the Interest Rate Cycle: Rethinking Monetary Policy Divergence among the UK, US, and Euro Area and Global Asset Allocation

After experiencing the most aggressive rate-hiking cycle in decades, major central banks around the world began cutting rates in sequence between 2024 and 2025. However, renewed conflict in the Middle East has pushed up inflation expectations again, leading to subtle divergence in the monetary policy paths of the UK, the US, and the euro area. For institutional investors, understanding the policy rate trajectories of the major economies and the inflation structure behind them is more critical than ever. Based on the latest official policy data and market background, this article analyzes the current stage of the interest rate cycle transition and explores its long-term implications for bonds, cash, and risk assets.

Market Background: The Evolution of Policy Rate Paths

The Bank of England gradually raised rates from a historic low of 0.1% in December 2021, reaching a cyclical peak of 5.25% in August 2023. Subsequently, as inflation declined, the Monetary Policy Committee cut rates by a cumulative 1.5 percentage points between August 2024 and December 2025, and in July 2026 decided to hold the benchmark rate at 3.75%. Notably, three committee members voted for a 25-basis-point hike at that meeting, indicating differing views within the committee on the inflation outlook. The Bank of England had originally expected CPI to return to around the 2% target in the second quarter of 2026 if the Middle East situation did not deteriorate; however, actual June CPI still came in at 2.6%, and the committee's latest central forecast shows that, once the impact of the conflict is included, inflation will rise to around 3.2% in the fourth quarter.

The Federal Reserve lowered interest rates to near zero in 2020 and launched large-scale asset purchases. Beginning in March 2022, the Fed raised rates continuously, pushing the federal funds rate to a peak of 5.25%-5.50% by July 2023. After confirming that inflation was cooling, the Fed implemented three rate cuts at the end of 2025, bringing rates to a range of 3.50%-3.75%, and held them unchanged in July 2026. At the same time, the Fed ended quantitative tightening in December 2025 and announced in that same month that it would resume purchases of short-term Treasury securities to smooth volatility in funding markets. This shift is noteworthy: although the Fed has paused rate adjustments, it is injecting liquidity into the market by buying short-dated bonds.

The euro area's monetary policy path is more complex. The European Central Bank cut rates eight consecutive times between June 2024 and June 2025, lowering the deposit rate to approximately 2.00%, before pausing. In June 2026, however, the ECB unexpectedly raised rates by 25 basis points to 2.25% due to an energy price shock stemming from the Middle East conflict, and in July it decided to stay on hold. This suggests the euro area may face a policy pattern of "two steps forward, one step back."

Current Capital Flows: How Policy Expectations Affect Asset Pricing## Current Capital Flows: How Policy Expectations Affect Asset Pricing

Although there is no direct flow data, we can still derive significant implications for capital allocation from the policy framework. First, official interest rates in the UK and the US remain far above pre-pandemic levels, but they have also declined from their peaks. In this environment of a “slow decline from high levels,” the nominal returns offered by money market funds and short-term Treasuries remain attractive. However, as the US resumes purchases of short-term Treasuries, short-end rates may face downward pressure, and the funding cost curve is flattening, thereby forcing investors to move along the yield curve to seek assets with longer duration to sustain returns.

In the UK, gilt yields have already priced in compensation for a rebound in inflation. The Bank of England’s quantitative easing asset holdings have fallen from a peak of £895 billion to £492 billion (July 2026), and quantitative tightening is still ongoing. The combination of increased asset supply and the central bank’s exit from purchases may put structural upward pressure on long-end yields, offering fixed-income investors a higher term premium but also intensifying concerns about gilt issuance and fiscal sustainability.

In the US, the Federal Reserve’s shift from “passive balance-sheet runoff” to “active short-end buying” is, on the one hand, aimed at avoiding extreme volatility in the short-term repo market, and on the other hand, may also signal that policymakers do not want monetary policy to overly restrict the economy. If short-end rates stabilize or even decline as a result, some allocation capital may rotate into corporate credit and long-term Treasuries, though the latter still face issuance pressure stemming from fiscal deficits.

The euro area, meanwhile, faces a unique “fragmentation” risk. Although the European Central Bank has the Transmission Protection Instrument, if rate hikes cause bond spreads of peripheral countries such as Italy to widen sharply, investors may be forced to seek refuge in core government bonds, further reinforcing the divergence between core and peripheral markets. For global investors, this means that management of intra-euro-area credit spreads requires greater caution than before.

Investment Logic Analysis: Structural Factors and Long-Term Trends

From a longer-term perspective, this interest-rate cycle is not a simple back-and-forth tug of war. After the pandemic, global supply-chain restructuring, the energy transition, and structural labor shortages have changed inflation dynamics. The reaction function of major central banks has shifted from “maintaining growth” to “anchoring inflation.” Even if the Middle East conflict eases, the central tendency of inflation is likely to remain above the 2010s average. This implies that the nominal neutral rate may have risen structurally, and the long-term level of real rates may also be higher than the norm of the past decade.

For asset allocators, this environment means:

• Bonds regain their strategic role in diversifying equity risk. In a scenario where high inflation subsides but policy uncertainty remains elevated, the hedging value of duration still exists, yet the fiscal-monetary interactions across different countries need to be carefully distinguished.
• Cash is no longer a risk-free option. As the Fed resumes purchases of short-term Treasuries, short-end yields may be pushed lower, and real purchasing power will be eroded under medium- and long-term inflationary pressures. Institutional investors need to convert excess cash into more productive assets.
• Equities and real assets may become less sensitive to policy rates and instead more sensitive to earnings growth and margin prospects. The European Central Bank's surprise rate hike reminds us that inflation rebounds driven by supply shocks can recur; whether corporate pricing power is solid is central to judging the long-term trend of individual stocks and sectors.

What structural factors are driving the changes? Geopolitics is the biggest new variable. The Middle East conflict directly impacts energy prices, forcing central banks into a difficult trade-off between controlling inflation and maintaining financial stability. Meanwhile, the role of fiscal policy is being reassessed. The Fed's quick resumption of bond purchases after ending balance sheet reduction is, in effect, an acknowledgment of the close link between government debt management and the functioning of money markets. In the coming years, whether fiscal dominance will weaken central bank independence is a key risk that long-term investors must incorporate into scenario analysis.

Risk Factors

On the macro risk front, the policy paths of major central banks remain heavily data-dependent. If energy prices surge again and continue to feed through to core inflation, the Fed and the Bank of England could be forced to resume rate hikes. Reference data show that the Bank of England has revised its inflation peak forecast up to 3.2%, with the balance of risks tilted to the upside.

On the policy risk front, the Bank of England still plans to further reduce its asset holdings over the next 12 months, implying that absorption pressure in the gilt market may persist. The Fed's shift toward buying short-dated Treasuries, while helping to stabilize funding markets, may also be seen as "quasi-fiscal operations," raising concerns about moral hazard and challenges to monetary independence.

Geopolitical risks cannot be ignored. Further escalation of the Middle East conflict could disrupt global trade, shipping, and supply chains; if tail scenarios that the market has not fully priced in materialize, they could easily trigger a synchronized drawdown in risk assets.

Market valuation risks should also not be underestimated. In an environment where rate cuts fall short of expectations or inflation recurs, long-duration equity assets—especially growth sectors with elevated valuations—may face a dual squeeze from earnings expectations and real interest rates. The European Central Bank's rate hike in June 2026 has already shown that central banks still prioritize inflation control; if real rates remain elevated, the repricing of long-duration risk assets may have only just begun.Looking ahead over the next 3–10 years, the global monetary policy framework may need to adapt to a more conflict-ridden and fragmented world. The extremely accommodative environment of the three major central banks in the 2010s is a thing of the past. Even after successfully controlling inflation, most advanced economies are unlikely to return to near-zero interest rates. A more likely scenario is rates moving in waves within the 2%–4% range, with policy increasingly driven by supply shocks and fiscal conditions.

This landscape offers several directional implications for long-term investors:

• The importance of real assets is rising. Infrastructure, natural resources, and real estate may provide a hedge against imported inflation and benefit from capital expenditure cycles related to reindustrialization and energy security.
• Sovereign credit divergence will become the norm. Against a backdrop of widening differences in fiscal quality, correlations among government bonds of different sovereign economies may decline, making active credit selection and country allocation more critical.
• Emerging market opportunities will emerge amid cyclical dislocations. Current policy uncertainty in Europe and the United States may restrain capital flows; but once major central banks embark on a clear easing path, capital seeking real growth may rotate back toward Asia and commodity-exporting countries.
• The return sources of alternative assets and private equity will no longer be simply falling interest rates, but rather deep active allocation across corporate restructuring, digital transformation, and clean technology value chains.

Institutional investors should recognize that monetary policy data is an important starting point for understanding markets, but not the end point. In a new landscape shaped jointly by geopolitics, fiscal policy, and productivity evolution, disciplined asset allocation, stress testing, and cross-asset risk monitoring will become key capabilities for navigating cycles.
