For two decades of low and stable inflation, many households and pension funds relied on a simple mix of 60 percent stocks and 40 percent bonds to grow savings and cushion market shocks. When inflation surged in 2022 and interest rates jumped, that balance delivered one of its weakest years in generations.
Between 2022 and 2025, investors have searched for ways to keep pace with higher prices and more frequent supply disruptions. The result is a gradual shift toward portfolios that combine traditional stocks and bonds with real assets and a cautiously sized exposure to digital assets.
Global inflation reshapes 60/40 portfolios
The 60/40 model was designed for an environment in which falling inflation supported both rising stock prices and steady bond gains. The spike in consumer prices in 2022, reflected in global inflation data, pushed central banks to raise policy rates sharply. That combination dragged down both sides of the classic mix and exposed how vulnerable a single formula can be when inflation surprises.
Real assets such as listed infrastructure, real estate securities, commodities, natural resource shares and inflation-linked bonds have moved closer to the center of portfolio discussions as a result.
Studies of past market cycles show that baskets of these assets have often held their value, or outperformed global equities, in multi-year periods of elevated inflation. Because their cash flows are tied to physical capacity, transport networks, buildings and resource extraction, they also respond differently to economic slowdowns than broad stock indexes.
Future portfolios add Bitcoin cautiously
Alongside this renewed interest in tangible assets, digital instruments built on blockchains are starting to claim a small but visible place in diversified portfolios. By mid-2025, the value of all Bitcoin in circulation had climbed above two trillion dollars, and exchange-traded funds allowed investors to hold it through familiar brokerage accounts.
Tokenised versions of government bonds and money-market funds have also grown into a market measured in tens of billions of dollars, blurring the line between traditional finance and crypto markets.
Even with that growth, most professional allocation frameworks treat cryptocurrencies as a speculative add-on rather than a core holding. Surveys of financial advisers and risk-model tests typically cap suggested crypto exposure in the low single digits of a total portfolio, with one to three percent often used as a range that can influence long-term returns without dominating overall risk.
