Hubbis Macro Corner: Sticky Inflation, AI Breadth and New Diversifiers Shape Portfolio Thinking


At a Glance

  • Inflation has cooled, but several investment houses are resisting the idea that the problem is solved. Eastspring noted that softer July inflation pushed the market-implied probability of a September Federal Reserve rate increase sharply lower, while Citi argued that underlying inflation remains stuck above target and price pressures are still moving through the goods pipeline.

  • Artificial intelligence (AI) leadership has reasserted itself, supported by earnings rather than valuation expansion alone. Eastspring highlighted exceptionally strong US second-quarter earnings and renewed hyperscaler spending plans, while Invesco argued that improving demand, market breadth and earnings continue to challenge the bearish case.

  • Asia remains one of the clearest beneficiaries of the AI capital-spending cycle. Korea and Taiwan led recent regional equity gains, while stronger technology exports have contributed to better-than-expected growth in Korea, Singapore and Malaysia. Source
  • Higher long-term yields are reinforcing the distinction between income and duration risk. Wells Fargo Investment Institute favours shorter maturities as a way to capture attractive yields while limiting sensitivity to further increases in long-term rates, and its separate 19 August analysis warned that inflation and rate volatility remain significant risks for bond investors.

  • Portfolio diversification is expanding beyond conventional asset classes. Wells Fargo has formally introduced digital assets into its strategic capital-market assumptions and recommends only modest allocations for growth-oriented portfolios, while continuing to emphasise their substantially higher volatility.

Investment research published this week presented a market that remains fundamentally supportive of risk assets but increasingly intolerant of simplistic narratives. Inflation has moderated, corporate profits remain strong and the AI investment cycle continues to drive activity across the US and Asian economies. Yet long-dated bond yields remain elevated, some measures of underlying inflation are proving sticky and equity leadership is still concentrated enough to justify caution. The resulting message is not to retreat from markets, but to broaden return drivers, control duration and distinguish genuine fundamental growth from positions whose valuations already assume near-perfect execution.

Inflation Is Cooling, but the All-Clear Remains Elusive

Eastspring Investments’ 17 August CIO bulletin captured the rapid change in expectations following July’s inflation data. Core Consumer Price Index (CPI) inflation slowed to 2.5% year-on-year and core Producer Price Index (PPI) inflation to 4.2%, prompting markets to reduce the implied probability of a September Federal Open Market Committee rate increase to 29%, from more than 72% following July’s hawkish policy hold. Markets were also no longer fully pricing another rate increase before year-end. Source

Eastspring nevertheless cautioned against treating lower inflation as the end of the tightening debate. Persistent fiscal concerns continue to lift the term premium and steepen the US Treasury curve, while underlying inflation remains meaningfully above target. If long-term yields themselves tighten financial conditions sufficiently, the Federal Reserve may be able to remain on hold for longer; renewed energy or geopolitical pressure, however, could quickly revive inflation concerns. Source

Citi Wealth took a more hawkish interpretation in its 18 August weekly update. Its preferred measure of underlying US inflation, the Cleveland Fed’s 16% trimmed mean, was running at 2.6% year-on-year, with the July reading and 2026 year-to-date pace both annualising at around 2.7%. Citi therefore argued that inflation has moderated from its peak but appears to have stalled somewhere between 2.5% and 2.75%, rather than returning cleanly towards the Federal Reserve’s 2% objective. Source

The breadth of price pressure was also important. Citi found that roughly one-third of CPI components were increasing at an annualised monthly rate of at least 5%, compared with around one-quarter before the pandemic. At the corporate level, approximately 30% of smaller US businesses have been raising average selling prices during 2026, compared with about 7% before Covid. That is substantially better than the 2021–2022 peak, but still inconsistent with a fully normalised inflation environment. Source

Citi also highlighted pressures earlier in the manufacturing pipeline. Core unprocessed-material prices were rising by 19.6% year-on-year, processed materials by 8.2% and finished goods by 3.6%. Because inflation at earlier production stages can feed into finished goods with a lag, the firm sees little justification for assuming that recent softer headline releases will automatically continue. Its conclusion remains that the next material move in policy rates is more likely to be higher than lower. Source

The distinction between these views is useful. Eastspring sees softer inflation and tighter financial conditions reducing the urgency of another increase; Citi sees persistent underlying and pipeline inflation preserving the case for tighter policy. Both, however, reject the simpler proposition that the inflation issue has disappeared.

Bond Investors Are Being Paid More — but Duration Still Requires Conviction

The uncertain inflation outlook remains particularly important for fixed income. Wells Fargo Investment Institute’s 19 August commentary argued that July’s weak jobs and retail-sales reports had made the timing of any Federal Reserve move more difficult to predict, but that elevated inflation and uncertainty surrounding oil prices would continue to generate significant volatility in both inflation expectations and interest rates. Its preferred response is to limit that volatility through greater emphasis on shorter-term bonds. Source

Wells Fargo’s broader weekly strategy publication reached the same conclusion from an asset-allocation perspective. Long-term Treasury yields have risen markedly, leaving longer-maturity bonds particularly vulnerable if the term premium, inflation expectations or fiscal concerns push rates higher again. Shorter maturities, by contrast, continue to provide attractive income without locking investors into as much duration sensitivity. Source

This is not a negative call on fixed income as an asset class. It is a distinction between earning yield and making a directional duration bet. Current income is once again a meaningful contributor to expected bond returns, but moving significantly further out along the curve requires confidence that inflation, fiscal issuance and the term premium will not overpower the benefit of eventual monetary easing.

For wealth portfolios, that distinction is particularly relevant where bonds are expected to provide both income and capital preservation. A short- or intermediate-duration quality allocation can deliver meaningful carry while retaining more flexibility to reinvest if yields rise further. Long duration can still perform strongly in a genuine growth shock, but it is increasingly an active macroeconomic position rather than an automatic source of diversification.

AI Leadership Returns as Earnings Reinforce the Investment Cycle

Eastspring’s research found that softer rate expectations combined with exceptionally strong corporate results had moved market leadership back towards growth. More than four-fifths of S&P 500 companies had beaten second-quarter earnings-per-share expectations, while aggregate profit growth was running at its fastest pace since 2021. Continued upward revisions to hyperscaler AI infrastructure spending reinforced expectations that the investment cycle can continue to support earnings across the wider ecosystem. Source

Invesco’s 17 August analysis made the broader bull-market case. It argued that several arguments previously used against equities have weakened as AI demand has proved more durable, earnings have improved and market participation has broadened. In particular, continuing adoption of AI agents could sustain demand for computing capacity for years, making today’s infrastructure build-out less analogous to a purely speculative capital-spending bubble than headline expenditure numbers might imply. Source

The distinction between capital expenditure and unproductive capital expenditure is becoming central to the debate. Huge spending numbers are not in themselves evidence of a bubble if utilisation, revenue and productivity expand sufficiently to support them. Conversely, strong secular demand does not guarantee attractive returns for every company supplying capital to the theme. As the AI cycle matures, free cash flow, return on invested capital, competitive position and the ability to monetise installed capacity become increasingly important differentiators.

That is also why broader participation matters. A healthier market would see AI-driven investment benefits move beyond a narrow group of semiconductor and hyperscaler companies into power infrastructure, industrial equipment, software, automation, logistics and other businesses servicing the physical and digital build-out.

Asia Remains Closely Leveraged to the AI Spending Cycle

The revival in AI enthusiasm has been particularly visible across Asian markets. Eastspring reported that Korea and Taiwan led regional equity performance over the preceding two weeks, with foreign flows turning positive following a period of significant withdrawals. Markets experiencing the strongest earnings revisions were also the strongest performers, suggesting that fundamentals had again become the dominant driver of regional leadership. Source

Technology exporters remain the most direct beneficiaries. Strong AI-related exports have contributed to better-than-expected second-quarter economic growth in Korea, Singapore and Malaysia, showing how technology demand is increasingly important not just to listed-company earnings but also to national economic performance. This creates a powerful positive feedback loop when capital expenditure remains strong: export revenues improve, earnings estimates rise and foreign investor flows can return to the same markets. Source

The concentration of that exposure remains a risk. Markets most closely tied to memory, semiconductors and other AI infrastructure can benefit disproportionately when spending expectations rise, but they can also experience abrupt reversals when investors question future capital expenditure. For wealth managers allocating to Asia, country selection and sector look-through therefore remain essential; a regional equity allocation may contain considerably more AI-cycle exposure than its broad geographic label suggests.

The rates backdrop is becoming somewhat less restrictive for Asia as well. Eastspring noted that reduced expectations for imminent Federal Reserve tightening weakened the US dollar and generated a relief rally in Asian currencies. Softer-than-expected inflation across much of the region has also reduced pressure on local central banks to tighten aggressively in the near term, although Eastspring still expects most Asian central banks eventually to remain in or move further into tightening cycles, with China and Thailand notable exceptions.

Strong Markets Are Creating Their Own Portfolio Risk

Not every manager interpreted the recent equity strength as an invitation to add risk. Wells Fargo’s 17 August strategy note argued that the S&P 500 was approaching overbought territory following a 6% increase from its 29 July low through 10 August. Importantly, much of that advance had again been driven by a relatively narrow group of AI-related technology and consumer companies, while the equal-weighted index had risen much less. Source

Investor sentiment was another concern. Low implied volatility alongside strong momentum and narrow leadership can make markets more vulnerable to unexpected setbacks. Wells Fargo did not turn broadly bearish, but suggested that investors use recent strength to rebalance portfolios and trim positions that have grown materially beyond strategic target weights. Source

This creates an important distinction between the tactical and strategic outlook. Invesco sees fundamental reasons for the bull market to continue, while Wells Fargo sees enough short-term optimism to justify disciplined rebalancing. Those views are not necessarily contradictory. A portfolio can remain strategically constructive on equities and AI while reducing concentration created by exceptional recent performance.

For high-net-worth investors, this is especially relevant where successful technology holdings have become much larger than originally intended. Rebalancing does not require abandoning a structural growth thesis; it can simply prevent one theme from becoming the dominant determinant of portfolio outcomes.

Digital Assets Enter the Strategic Asset-Allocation Conversation

One of the more significant portfolio-construction developments this week came from Wells Fargo Investment Institute, which formally introduced digital assets as an asset class within its capital-market assumptions. The firm said improved regulation, institutional adoption, custody infrastructure and access through spot exchange-traded funds have made the asset class sufficiently investable to consider within a conventional strategic allocation framework. Source

The allocation recommended is deliberately small. Wells Fargo proposes 2% for Growth & Income objectives and 3% for Growth portfolios, funded through a modest reduction in US mid-cap equities. It does not recommend digital assets for Income portfolios because the volatility remains incompatible with a more conservative objective. Source

The research estimates a long-term geometric return of 11.2% for digital assets alongside expected volatility of around 40%. Their historical correlations with conventional asset classes have generally remained low over longer periods, although correlation with US equities can rise during shorter periods of market stress. The strategic argument is therefore based on a combination of return potential and differentiated long-term behaviour rather than any assumption that digital assets provide reliable protection during equity drawdowns. Source

For family offices, the significance is less the precise 2% or 3% allocation than the methodological shift. Digital assets are increasingly being assessed through the same expected-return, volatility, correlation and portfolio-impact framework applied to conventional asset classes. That does not remove their regulatory, liquidity, operational or valuation risks, but it moves the discussion from whether the category belongs in institutional portfolio analysis at all towards what size and structure of exposure, if any, is appropriate.

Gold Retains Support, but the Opportunity Cost Has Risen

Wells Fargo also remained favourable on precious metals after gold recovered more than 7% during the first week of August. It cited geopolitical uncertainty, renewed central-bank purchases and improving exchange-traded fund flows as structural support, while noting particularly persistent demand from Asian investors. Source

The headwind remains US real yields. Gold does not generate income, making it less attractive relative to bonds when inflation-adjusted yields rise. Wells Fargo therefore expects the path higher to remain uneven and lowered its year-end gold-price targets for both 2026 and 2027, even while retaining its favourable strategic view. Source

This reflects a broader portfolio theme running throughout this week’s research. Assets that once competed against near-zero-yielding bonds now face a materially higher hurdle. Whether investors are considering gold, growth equities, real assets or alternatives, the availability of meaningful risk-free and high-quality fixed-income yields changes the opportunity-cost calculation.

What This Means for Wealth Managers and Family Offices

For private banks, independent wealth managers and family offices, the first priority is to separate softer inflation from solved inflation. The reduction in immediate Federal Reserve tightening expectations is supportive of markets, particularly rate-sensitive growth assets and Asian currencies, but Citi’s evidence of elevated trimmed-mean inflation and building pipeline price pressures argues against constructing portfolios on the assumption that rates can only fall from here. Source

Fixed income continues to offer genuine portfolio value, but duration should be intentional. Shorter and intermediate maturities can capture much of the available income with less sensitivity to fiscal, inflation and term-premium shocks. Longer-duration bonds may still provide substantial upside if growth weakens sharply, but they increasingly represent a macroeconomic conviction rather than the default defensive allocation they once were.

AI exposure should be assessed at total-portfolio level. US growth stocks, Korean and Taiwanese technology exporters, infrastructure, power demand and even national growth rates increasingly share the same underlying capital-expenditure driver. A portfolio diversified by security or geography can therefore still be economically concentrated in the AI cycle. Eastspring’s evidence from Asia makes this particularly relevant for global investors. Source

Equity rebalancing is becoming more important precisely because the fundamental backdrop remains strong. The case for reducing oversized winners does not depend on forecasting a bear market. After powerful gains and renewed concentration, systematically returning portfolios towards strategic weights can preserve exposure to long-term growth while reducing the damage that would result from a reversal in the most crowded positions. Wells Fargo source Invesco source

The definition of a diversified portfolio is continuing to evolve. Wells Fargo’s decision to incorporate digital assets into its strategic framework is one example, but the more general lesson is that new return drivers should be judged by what they contribute to total-portfolio outcomes rather than by novelty alone. Expected return, volatility, liquidity, correlation, governance and implementation risk remain the relevant tests. Source

The week’s research ultimately supports a constructive but disciplined stance. Corporate earnings and AI capital spending remain powerful economic and market supports, particularly in the US and parts of Asia. Yet sticky inflation, higher long-term yields and concentrated positioning leave less room for mistakes. The strongest portfolio case is therefore not simply to add or reduce risk, but to improve the quality and diversity of the risks being taken.
