Recent geopolitical flashpoints have forced a critical examination of whether wealth managers truly understand the deepest risks embedded in client portfolios. While headlines focus on immediate commodity shocks like oil, the deeper systemic threat lies in the quiet, secondary shifts that erode the value of assets.
In this interview, Ronald Ratcliffe, the managing director and head strategist for portfolio analytics at BlackRock Aladdin, discusses how macro forces like inflation drive portfolio risk, why traditional diversification fails, and how technology helps analyse true exposures across public and private assets.

PBI: Now that the US-Iran conflict has evolved and markets have adapted, what did this episode reveal about how wealth managers still assess portfolio risk?
Ronald Ratcliffe: Most investors started by asking which holdings were exposed to oil. That’s understandable, but the bigger issue was what the conflict meant for inflation, interest rates, currencies and risk premia across the entire portfolio. The initial market reaction eased, but the questions around inflation and rates didn’t disappear with it.
More broadly, the market response reinforced a feature of the current environment: geopolitical tensions can create episodes of macro volatility without producing a sustained, broad-based risk-off market. Portfolios are still often organised around asset classes, but markets increasingly move around macroeconomic forces. For years, stable inflation helped smooth a lot of that complexity. That’s no longer something investors can take for granted.
Many traditional portfolio frameworks were developed during a long period of relatively stable inflation and declining rates. Today, benchmarks are not simply reference points; they’re a set of assumptions about growth, inflation and risk. That’s one reason wealth managers are spending more time on whole-portfolio analytics. The focus is shifting from where an investment sits in the portfolio to the underlying economic exposures it brings to the portfolio.
PBI: Oil got the headlines, but the impact went much wider. Where did the real second-round risks show up in client portfolios and how does technology help investors manage those impacts?
Ratcliffe: Oil was the first-order exposure. The more important portfolio question was the second- and third-order effects: how higher energy prices fed into inflation expectations and then into rates, bond yields, credit spreads, currencies and equity valuations. That’s why portfolios with little or no direct energy exposure still felt the effects.
One of the challenges for wealth managers is that investments sitting in different parts of a portfolio often share the same underlying risk drivers. Two investments can sit in completely different asset classes and still carry exposure to the same underlying macro factor. A portfolio can therefore look diversified by asset class while being concentrated by risk factor. A portfolio can look diversified on paper while expressing the same view on growth, inflation or rates in multiple ways. Technology helps by looking through asset-class labels.
PBI: Looking back at the past few months, which risks were obvious, and which ones were building more quietly beneath the surface? How can investors use technology to prepare?
Ratcliffe: The obvious risks were geopolitical as investors focused on escalation in the Middle East, disruption through the Strait of Hormuz and the possibility of another energy-driven inflation impulse. The more interesting risks were developing in the background, one of which was the continued normalisation of term premia after years of unusually low levels.
Another was the changing relationship between equities and bonds; diversification still works but not always in the way investors became accustomed to during the post-financial-crisis era.
PBI: Did this period expose weaknesses in the traditional diversification story? What looked diversified on paper but did not hold up in practice?
Ratcliffe: Many portfolios appeared diversified because they held different asset classes, but when markets came under pressure, those assets often responded to the same underlying forces, particularly inflation and interest rates. The question becomes even more important in private markets. For example, Cambridge Associates’ US Private Equity Index returned -4.3% in 2022, compared with -17.6% for its S&P 500 public-market equivalent. Some of that reflected genuine differences in ownership structures and some differences in valuation timing. For wealth managers, that distinction matters as stability in reported valuations isn’t necessarily the same as resilience in underlying risk.
The real test of diversification isn’t how many asset classes you own. It’s how many genuinely independent sources of risk and return the portfolio contains.
PBI: How should wealth managers think about risk when public markets reprice instantly, but private assets appear calmer simply because they move more slowly?
Ratcliffe: The first thing to remember is that valuation frequency isn’t the same thing as risk. Private assets often look smoother because they’re valued less frequently, not because they’re immune from the same economic forces affecting public markets. That’s becoming increasingly important as private markets move from being a specialist allocation to a core part of many portfolios. Today, close to one-fifth of institutional portfolios are in private markets, and wealth portfolios are moving in a similar direction.
What investors increasingly need is a consistent framework for analysing risk across both public and private assets. That’s one reason data has become so important.
For wealth managers, the key question isn’t whether a private allocation looks less volatile. It’s whether it’s genuinely reducing portfolio risk.
PBI: In a geopolitical shock like this, how do you tell the difference between market noise and a risk that actually calls for repositioning?
Ratcliffe: The simplest test is to ask whether the underlying regime has changed. Has the growth outlook changed? Has the inflation outlook changed? And has the risk premium investors demand changed? If the answer is no, a dramatic market move may be more noise than signal. If the answer is yes, then it’s worth reassessing the portfolio. Recent Middle East tensions are a good example. The immediate market reaction faded relatively quickly, but the longer-term questions about inflation, rates and risk premia didn’t.
PBI: What is the one lesson wealth managers should take from this conflict when thinking about using technology to manage risk across client portfolios?
Ratcliffe: Question assumptions more often. A lot of the rules investors became comfortable with during the era of stable inflation are being challenged. Asset-class labels don’t always describe behaviour and benchmarks aren’t necessarily neutral. And historical correlations aren’t necessarily as stable as many investors assume. Increasingly, clients want to understand not just what they own, but what risks they own, and how common drivers such as inflation, rates, growth, and credit can show up across seemingly different investments.
Technology’s role is also changing. Its value isn’t in predicting the next geopolitical event, as nobody consistently gets that right. The real value is helping investors understand their exposures before the next shock arrives.
The firms that navigate uncertainty best won’t necessarily be the ones that make the best forecasts. They’ll be the ones with the clearest understanding of the risks they’re already taking.
