As we enter the second half of the year, the global economy finds itself facing considerable uncertainty.

Despite a cautiously optimistic start to the year, with disinflation broadly on track and central banks tilting toward easing monetary policy, the conflict in the Middle East has presented a myriad of challenges to global markets.

At present, policymakers are grappling with the difficult combination of persistent inflation and slowing economic activity. It is never an easy balancing act, and history suggests these environments rarely remain static for long.

Recent economic data reinforces this picture.

In the US, consumer prices moderated last month after trending higher over the first half of the year, driven predominantly by energy costs, while core inflation has been relatively better behaved.

At the same time, labour market conditions have softened around the edges, hiring has moderated, consumers are becoming more cautious, and the cumulative impact of higher living costs is increasingly evident.

In the euro area, the disinflation story has also been interrupted by the energy shock, but activity was already fragile before the conflict, having contracted earlier in the year, and confidence indicators have since deteriorated further.

Meanwhile, China continues to grapple with subdued consumer demand and an extended period of adjustment in its property market. Despite periodic policy support measures, the economy has yet to regain the momentum many had hoped for at the start of the year.

Faced with this backdrop, policymakers have responded in a cautious, data-dependent manner.

The US Federal Reserve (US Fed) held rates steady through the first half of the year. In his first policy decision last month, new US Fed Chair Kevin Warsh removed explicit references to an easing bias and signalled his preparedness to wait for greater clarity before adjusting policy.

The European Central Bank (ECB) moved in the opposite direction, delivering its first rate increase since 2023 in a pre-emptive attempt to prevent higher energy prices from becoming embedded in inflation expectations, while also highlighting that risks to growth are tilted to the downside.

The Bank of Japan continued its gradual path towards policy normalisation, raising rates last month while maintaining a highly data-dependent stance.

The common thread is that central banks are facing difficult trade-offs. Inflationary pressures associated with supply shocks sit uncomfortably alongside an underlying growth backdrop that, outside of pockets of AI investment enthusiasm, appears increasingly fragile.

The takeaway for investors is that this policy configuration is unlikely to be stable.

For investors, it is worth remembering that supply-driven inflation shocks tend to contain the seeds of their own reversal. Higher energy prices ultimately reduce purchasing power, weaken demand and, over time, help cool inflationary pressures.

That is why we remain somewhat sceptical of the notion that materially higher interest rates are the most likely outcome from here.

History suggests that tightening policy into a growth slowdown carries meaningful risks. If energy prices were to moderate further as fragile ceasefire negotiations evolve, the disinflation path could resume more quickly than markets currently expect. On the other hand, if geopolitical tensions were to escalate materially, the drag on economic activity may ultimately become the dominate concern, prompting central banks to focus more on supporting growth and employment than restraining inflation.

In either scenario, current policy settings appear more likely to become easier than more restrictive over time.

If there is one lesson from the first half of the year, it is that economic narratives can change quickly.

While markets continue to debate the path of inflation, interest rates and geopolitics, investors should remain focused on the underlying fundamentals rather than the latest headline. The outlook remains uncertain, but uncertainty does not necessarily imply poor investment outcomes. More often, it reinforces the value of patience, discipline and a long-term perspective.
