Coming into 2026, investors face a landscape shaped by persistent inflation, evolving US monetary policy and global uncertainty. At Parametric, our systematic and customized approach is designed to help clients navigate these complexities while preserving after-tax returns.



The world economy has entered the new year at a crossroads, with growth expected to moderate and inflation gradually cooling across most regions. The International Monetary Fund (IMF), the World Bank and leading private forecasters project global GDP growth ranging from 2.6% to 3.2%—below pre-pandemic averages—as trade tensions, policy uncertainty and structural shifts weigh on momentum in 2026.


Let’s take a moment to focus on the trends shaping the investing environment.


Key global themes shaping 2026


AI Investment and Productivity. The US continues to lead in AI-driven capital spending, supporting growth and productivity. While AI adoption has been slower outside the US, its transformative potential is beginning to reshape labor markets and business models globally.


Trade and Tariffs. The new global trade order is defined less by tariff levels and more by their spillover effects. US tariffs are expected to dampen imports, limiting the transmission of US domestic strength to the rest of the world. China’s economy has become more export focused, and the basket of goods has shifted toward higher value-added products, intensifying competition for manufacturers in Asia and Europe.


Divergent Regional Growth. The US is projected to grow around 1.5% to 2.0%, supported by resilient consumption and continued AI investment. China’s growth has moderated to 4.0% to 4.6% as property sector challenges persist. Europe faces modest growth, with Germany rebounding on fiscal stimulus, while the UK and France contend with fiscal constraints. India continues its structural ascent, after surpassing Japan as the world’s fourth-largest economy in 2025.


Risks and Uncertainties. Major risks include a potential AI bubble, renewed inflation from supply bottlenecks, policy missteps and geopolitical tensions. Fiscal and monetary policy should remain in focus, with central banks cautious about rate cuts and governments balancing the need for stimulus with debt sustainability.


Major risks that may capture an investor’s attention can be bucketed into a few broad categories that I’ve defined. Here’s a visual summary of what I perceive to be the intensity of these risks by region, based on a qualitative assessment of recent headlines.

As investors consider these risks, we think it’s important to recognize how market dynamics are shifting. Earnings growth has broadened beyond technology. In the third quarter of 2025, S&P 500® Index earnings rose 14%, with most of the acceleration coming from sectors outside tech. More industries are now showing positive growth—highlighting that opportunity and volatility extend across the market, not just in mega-cap tech stocks. In our view, diversification* remains key as sector leadership evolves over the coming year.


Focusing on the US investment environment, let’s look more closely at some major themes:



Stubborn challenge of US inflation


Despite progress since the post-pandemic peak, US inflation remains above the Federal Reserve’s 2% target, with Headline CPI for December 2025 coming in at 2.7% year over year. Structural factors—including tariffs, energy bottlenecks, housing constraints and labor shortages driven by reverse immigration and an aging population—continue to exert upward pressure on prices. These forces suggest inflation is unlikely to normalize in the near term and may possibly rise, even as headline measures decelerate modestly. 


As noted in our outlook for commodities, investors tend to increase allocations to “safe-haven assets” like gold when market uncertainties like inflation persist.



New era of US monetary policy uncertainty


The Fed enters 2026 at an inflection point: Chair Powell’s term is set to expire in May, and the administration has indicated that his successor could be appointed early in the first quarter. Markets are bracing for potential shifts in the Fed’s tone and independence. Depending on how Powell’s replacement is perceived, we may see the yield curve steepen as term premiums rise. In that scenario, mortgage rates could remain elevated, adding to the headwinds faced by the US housing market.


As highlighted in our outlook for fixed income, active management may become a strategic differentiator in an environment defined by policy uncertainty and shifting interest rate dynamics.


Rules-based strategies for customized investing solutions to fit any portfolio

Election-year dynamics of US fiscal policy


Ahead of the November midterm elections, the current administration may offer a flurry of fiscal initiatives—ranging from tax adjustments to targeted spending programs—aimed at shoring up voter confidence. While such measures may provide short-term stimulus, they also risk widening operating deficits, which are currently projected to exceed 6% of GDP, and add to supply pressures at the long end of the bond market.
