2020年代後半の投資環境を再定義する「5つの構造的な力」

Hi everybody. It's so great to be here today with all of you. We really appreciate your taking the time out. Um we're going to make sure it's worth it. So, over the last year, the conversations that I've been having with CIOs, board members, long-tenured investors has changed. The questions are different, the tone is different, and the playbooks that they've relied on for years aren't working in quite the same way. And when that starts to happen across people that have been doing this for decades, I pay attention. Because it suggests that something more fundamental might be starting to shift underneath the surface. That's what I want to talk to you about today. Not a market outlook, not a 12-month forecast, but the forces that are starting to rebuild and reshape how capital is allocated, how returns are generated in portfolios, and how we make decisions. So, before we do that, I want to ask you this. Who here remembers where you were on November 2008 when this headline hit? Yep. Yep. Great. And how about this one in 2020? Two crises, two different setups going into them, and two very different recoveries. Do you remember how you felt? Maybe panic, uncertainty. I mean, for some, like pit in the stomach fear. Does it sometimes feel like we're starting to head towards that level of uncertainty? Or that there's a major rewiring that's happening in the markets? I remember the first time I felt that. It was in 1997. I was in at JP Morgan on the credit trading desk in Tokyo. It was during the Asian financial crisis. Volatility was unfolding in real time, spreads were blowing out, positions were moving. I remember thinking at the time, reading about volatility is very different than living through it. But more importantly, what I learned is that the hardest question to answer in these times isn't what just happened. It's is this temporary or is this becoming structural? After the GFC, banks pulled back and private credit stepped in. That was a structural shift. During COVID, we saw another structural shift as major policy moves to deal with near-term shocks has structural impact on major macro drivers like inflation. Now, I'm not saying that we need to have a major crisis to determine kind of whether structural change is happening. But misreading what's temporary and what's structural has real consequences. You can wait out a cycle. But you can't build a portfolio for a world that no longer exists. That's the core idea I want to leave you with today. What we're navigating right now isn't just a cycle. It's a shift in terms of how capital is allocated, how returns are generated, and how we're making decisions. And there's five forces that are driving it. So, I'm going to start with AI. Uh and you're probably wondering what Wednesday Addams has to do with AI and investing. So, Netflix is much less like a studio and much more like a real-time capital allocator of data. When they launched Wednesday, it wasn't just a creative bet. It was a data-driven decision that was driven by viewership, audience overlap, demand. They weren't just creating content. They were aligning content with timing and distribution to amplify demand. And the result, 1 billion views in the first month. They weren't creating demand. They weren't They They weren't um you know, shaping demand. They were reshaping it. That's what's happening in investing. We're not to it. We're starting to shape it. So, think about AI. At its core, you need proprietary data, unique data sets coming in, and that's going to help you identify patterns and help you find insights that hopefully are going to help you make decisions better. Right? And that's a feedback loop. And then it keeps on going through, you keep on building out your data set. When we're looking at managers and researching managers that say they're using AI, that's what we're looking for. Do they have the data sets? Do they have the insights that they're capturing? And is it translating into repeatable decision-making that's hopefully driving value? At Russell, we have an amazing data set of manager data, both qualitative and quantitative insights that we've developed over the past since the 1970s. It's impossible for a human to take all of that data and synthesize it at speed or scale. So, a couple of years ago, Evgenia helped us take AI and use that data set to start to drive new looking for patterns, looking for new insights to hopefully help us make better decisions as we're thinking about manager selection or how we're constructing portfolios. And all of it's being grounded in human judgment. The portfolio managers that you know, the manager researchers that everybody here in this room has interacted with, they're using that information to try to figure out if there's a manager that we haven't been focusing on that might have an edge, or one that's losing their edge, or if there's some concentration that's building up in portfolios. The way that we're combining manager data, market data, and portfolio data now, it's it's mind-blowing to me versus I'd never would have thought we'd get there versus a couple years ago. And so, it's not just about who's using AI. It's about who's actually creating value with it. Okay. So, the next bit of a rockier landscape they're going to head into. There's some things that we can control, like how we're deploying AI into our organizations, And others that we can't lead geopolitics. Right? So, we've all lived through elections, major policy shifts, yeah, and and different, you know, types of, you know, conflicts that are occurring. And for the most part, the impact on markets has been episodic. It does seem like these days that the impact of those things and the frequency of them is just going up. And more of it is because some of the stuff Zach was saying, it's more because of how we're interacting with news and data. It's in our pockets, right? Information is coming at us constantly. Markets are repricing in real time. It's a pretty familiar pattern. Headline hits, market reacts, and more often than not we're seeing a V-shape recovery. But what we've got to figure out, are these just moments that are going to be more episodic? Or is it starting to build into much more of a structural shift? Let's take infrastructure as an example. For most of us, it's, you know, airports, roads, bridges, how we power our iPhone. But in the investing world right now, infrastructure is at the center of the structural changes that are being driven by geopolitics. Right? Energy independence, rebuilding, reshoring. All of these things are capital intensive moments that are happening. And it's a great tailwind for infrastructure. If we looked at Q1, real assets and infrastructure were the one bright spot in terms of returns. Everything else is pretty much flat to down. Some of that is because of the inflation sensitivity and the the cash flow profile, you know, of infrastructure. And that's one of the reasons where we tend to be overweight real assets within a lot of our portfolios. Because infrastructure and real assets are at the center of a lot of these structural shifts that are being driven by geopolitics, and they have some pretty good portfolio benefits that you can also have. So, we all know that we can't predict the future. And we all know that for the most part, these events are going to still be binary. But the conversations that we're having are is there data and technology that can help us better look at those events, see the narratives, and look to see if it's starting to get priced into markets and into our portfolios. Cuz we want to build portfolios that are resilient. But we also need to make sure that we're building portfolios based on where the world is going. Okay, so based on where the world's going, how many people here thought you'd be talking about data centers as much as we do today? And how many people really know where data centers are represented in your portfolio? Think about it. It's real estate, it's infrastructure, it's liquid cooling, it's chips. It's across your portfolio in all different asset classes. Your venture portfolio, your public and your private credit book, infrastructure, your public equity book. We're also seeing it with companies. More and more companies, when they're issuing debt, they're doing it in the public or private markets depending on what makes most sense for them. You know, the features might be different, the collateral underlying it might be different, but it's the same issuer. This is one of the reasons why we're talking about how public and private markets are converging. And part of it is that this isn't new, right? This is a something that started happening after the GFC and it really accelerated in the past couple of years. And some of it, you know, is maybe because of the growth we've seen in private markets, but it's much more about how public and private are interacting with each other. Zach has said this, they're interconnected, they're interacting with each other. It's much less siloed than it used to be. And we need to be thinking about that as we're developing our investment teams and how we think about making decisions. We can't be thinking in silos as much, you know, anymore. Your teams need to be looking across the opportunities that we're going to thinking about what's that next dollar you want to allocate. Let's take real estate decisions an example. Public and private real estate are very different, right, in terms of exposures that you can get to. The private side is more of your core exposures. You have to think about multifamily rentals, retail, office. On the On the public side and REIT side, it's much more specialty sectors. Data centers, healthcare, you know, you have your you know, single-family rentals. So, very different exposures you can get across the two, but there are some sectors that overlap across both of them, and they can get pretty dislocated between the two, and there can be opportunities, you know, in terms of between public and private market if you're paying attention, both in terms of how you're designing and managing the portfolio. Ultimately, as you're thinking about what real estate should I have in my portfolio, it should be driven by the outcome you're trying to achieve and certain themes that you want in the portfolio. But, you definitely should be looking at it holistically when you're making those decisions across public and private. There's just this interaction and an integration that's starting to happen more and more. Now, I can't talk about public and private markets convergence without talking about the real considerations that we all grapple with when we're thinking about how large my private allocation should be around transparency, cost, liquidity, and increasingly what type of vehicle you're accessing it in. That's obviously gotten a lot of headlines over the last like couple of months in terms of private credit. But, when you think about like how you're kind of accessing, you know, these markets and and what you want to do there, you know, it's not about like going, you know, do I pick one versus the other? Some of these things are starting to improve a lot. I would posit that data and transparency over the next couple of years for private markets is going to improve materially. It's because that we have a lot more data, and you also have investors that are demanding it. That's going to start to shift, and that is going to change how we're thinking about public and private markets, not just how we design the portfolio, cuz we're all doing that right now, but how we're managing it. And so, it won't be about public versus private. It's going to be about where's that next dollar of capital they want to allocate to, and then do I need to shift between the paths that I can take. Okay. So, for next one, diversification. And this is going to be one I'm going to have to do my best to keep shorter cuz I could talk about this forever. But I'm going to start with what the heck British take on Mexican food has to do with diversification. So when I was preparing for this, I was in London about a month ago. And I was thinking about how over the last 30 years of me living in and visiting London, the food has changed massively. When I was there in college in the '90s, it was pretty grim. You had beer, fish and chips, maybe a roast pizza with corn on it. Right? You know, and then the EU had lots of benefits. Here I saw a couple of faces in the audience. It's not good. It doesn't taste good. Um When I was in So when I got there during the GFC, things had changed you know, materially. You know, there was you know, Japanese, there was Greek, there was Thai. I was super excited for all the choices. But was it all good? I mean, has anybody had a good street taco or nachos in London? Not really. Yeah. So it's not just about having more choice. It's about having the right ingredients combined in the right way and prepared by experts that know how to make the dish. I mean, it actually sounds a lot like portfolio diversification. I mean, think about it. Over the last 20 years, the number of asset classes that we have access to has just multiplied. Right? Venture, private credit, infrastructure, even digital assets like crypto. So we've got more choice and I think everybody in this room has gotten a lot better about thinking through and seeing how different asset classes operate in different market environments. So it's not going to be when we think about building a diversified portfolio just about active, passive, public, private, which factors do I have exposure to. We can be much more deliberate about the types of asset classes across the whole, you know, universe that are going to best help us achieve our outcome. So I have to take a little bit of a sidebar. If we're talking about diversification, I feel like we have to talk about the rise of passive that we've had. It solves a lot of problems and concerns that we as investors had around cost as well as where's the best place to target alpha within a portfolio. But indexes have gotten a lot more concentrated you know, over the last 10 years. And so when we're thinking about diversification, we need to make sure that some of these default moves that we've been using that we're not missing out on the fact that with the diversification in portfolios actually has gotten a little bit worse as people have shifted to passive into these much more concentrated indexes. So just something that we need to keep on thinking about. But I'm going to hit on in a little bit more depth some of the comments that Grace made on a couple of asset classes, hedge funds and private credit. Just to bring some of this to life. So after the GFC, my experience was most clients didn't want to talk about hedge funds anymore. The fees were high, rates were low, liquidity was abundant, volatility was low, and they just weren't performing in the same way. But now you've got higher rates, higher vol, higher dispersion, and you also don't have to look at hedge funds as an asset class. Right? And you don't have to allocate to it just to get low correlation within the portfolio. That's a feature, but that's really that's just the first step. There are certain hedge funds that can really change how you're kind of building a broader diversified portfolio at the top level. So there are some hedge funds that we all know that track trend. And others that are really good at managing and benefiting from shifts in volatility. If you combine those two types of hedge funds in a portfolio that has a lot of equity in it, it can be pretty helpful in certain types of market shocks and complement your fixed income portfolio. You never know where the shock's coming from. If it's inflation, your fixed income is not going to help you a whole heck of a lot. Some of these hedge funds could. In the first quarter, small example, where we saw that most asset classes were flat to down other than real assets, hedge funds, those types of hedge funds I was mentioning were up 5 to 7%. Okay, now I'll shift to private credit cuz you can't go throughout the day without talking about private credit these days. And a lot of clients stayed on the sidelines for many years because of cost, liquidity, and complexity of private credit. Some of our E&F clients, they didn't want to consider private credit more because it just wasn't hitting the return hurdle for their private sports portfolio. But we know that market's gotten a lot broader and a lot deeper. And we also know that um objectives have changed in the past couple of years for lots of different organizations. Private credit is not just sponsor-led direct lending. It is a broad universe that's continuing to get deeper. And there's so many levers we can pull when we're building a portfolio that includes private credit. There's yield, cash flow, the underlying collateral quality as Grace had mentioned. Like obviously the duration. There's so many different levers that you can pull. So if you're a pension that's well-funded and has a lot of your assets in LDI, putting some investment-grade private credit in the portfolio to diversify your public credit, to pick up some more yield, to continue to build some surplus, and still have an effective liability hedge can be pretty powerful. In a hospital system, thinking about like a medium-term pool of capital, you can add an investment-grade private credit to get some extra yield, some liquidity that might be very aligned with the capital projects you've got 5 years out that you're planning for. So we know that no asset class is a silver bullet when you're designing portfolios, but we've got a lot of choice now, and we've got to be much more deliberate about which ones we're using for the outcome that we're trying to achieve. Right. Diversification is no longer going to be about assuming that you're diversified based off of long-term assumptions and averages of asset classes. It's going to be much more deliberate in terms of how you design it. Right. And probably much more active. Okay, the fifth force. The rise of the retail investor. Not the most obvious topic for an institutional conference, but retail assets are moving fast. Retail assets are expected to outpace institutional assets by the end of the decade. And this isn't a new phenomenon. We're seeing this. Like 20 to 25% of US equity flow is driven by retail right now. It's much more in the option space. And retail investors have very different objectives, you know, than institutional investors. They care about taxes, they care about liquidity. They think they have a shorter time horizon. We probably need to work with them on that. They probably have a longer time horizon than they realize. They don't have the same institutional checkpoints that we have as institutional investors. Investment committees, boards they need to run decisions by. They might have a partner or spouse, but increasingly they're they're looking at Reddit to get their advice. And they can move fast. And part of it is because they can just with a click of the phone, they can be accessing the market. And so they are they're just set up to, whether it's narratives or momentum, move much quicker. And we're seeing it. We're seeing in buy the dip mentality, except for this last month. And we're seeing it in options volume. You're seeing the retail flows. And that's not something new to track. I'm Paul and the team when we think about how sovereigns are starting to impact commodities in FX. We've looked at that for decades. If you think about pensions rebalancing at month end and quarter end, we're focused on what the impact is going to be on equity and fixed income markets. What's different here is that retail investors have the speed, the scale, and now the access to be having much more of an impact on market pricing. So, who here remembers uh 2020 and AMC and GameStop and the meme stock rally? Yeah. And who here had family and friends that asked you if they were good buys? Yeah. Yeah. I mean, it's kind of unfortunate that our loved ones think that what we do is trade meme stocks. So, you got to help them with that. Yeah. But at the end of the day, this is not a a shift that's going to happen overnight. Institutional money, 401(k)s, and advisors are still going to be the anchor in terms of the market. But retail participation is going to start to have more of an influence on the market and market action, and we need to be much more aware of it. Fundamentals are going to drive long term. And we know that most of these things are going to be noise, but we've got to be able to distinguish between when it's noise and when we need to take an action. And I will say as an institutional investor, as more individuals become investors, we need to help them understand all the things that we've learned over decades so they can continue to build their wealth and retirement. Okay. So, thank you for sticking with me through the five forces. These fundamental shifts that are driving these forces are not isolated. They're reinforcing each other, and we're going to talk about them throughout the day today. But AI is changing how we're making decisions, geopolitics is changing how capital is flowing, public and private markets are converging, diversification needs to evolve alongside that, and retail is going to have impact on the market, you know, as well as our industry. Each of these individually matter, but together, they really are changing the power dynamic of the market that we're operating in. So, what does this mean for portfolios? It's still developing. Structural change takes time to take hold. This is not a call to action to make major shifts in in portfolios. We all know that acting early is the same as being wrong in our world. But this these types of forces are really driving the decisions that we're making, the debates we're having, and a lot of the research that we're doing. And that honestly has made such an exciting time to be working at Russell and working with all of you. We have the data, we have the tools, we have the external manager reach, and the perspective to bring it all together. So, through all of this and all this talk about change, the one thing I would leave you with is that the one thing that is not changing is AI can't replicate judgment. AI can't replace people. Right? And the people that you have at the table pushing you, asking you questions, making you make smarter decisions, that all matters as we're dealing through all this change. So, for me, that's why this room matters a lot and kind of getting your perspective and getting the time that we spend with you to try to make the portfolios better so we can build portfolios for the future. So, thank you so much for your partnership and thank you so much for spending the day with us.

以下は、2026年1月21日にラッセル・インベストメント(米国)のHPに掲載された英文記事を翻訳したものです。原文はこちら

主なポイント

  • 運用の成果は、固定されたアセット・アロケーションそのものよりも、戦略的なポートフォリオ構築、運用機関の判断、そして市場横断的な視点が一層重要となっている
  • 分散投資の考え方は、従来の資産クラスの組み合わせ(アセット・アロケーション)から、リスク設計・サイズ・市場局面に応じた全体最適化へとシフトしている
  • AI の進展、プライベート市場の拡大、リテール資金の増勢、地政学的な分断の深刻化といった構造的要因が、リターンの源泉とポートフォリオの強靭性を大きく変えつつある


投資の原則は本来、固定的なものではありませんが、これほどまでに明確かつ急速に変化した局面は多くありません。市場のバブルや金融危機、自らを省みる大きな教訓となる出来事を通じて、長期的に成果を上げるためには、市場環境の変化に柔軟に適応する姿勢が欠かせないことを学んできました。現在はまさに転換点にあり、市場やポートフォリオに関する長年の前提が試され、覆されることもあります。

2020年代前半は、市場構造を大きく変える出来事が相次ぎました。政策変更によるショック、サプライチェーンの再編、急速なインフレ、テクノロジーや人工知能(AI)の急速な進展により、変化のサイクルが大幅に短縮されています。従来のパターンはより早く崩れ、相関関係は弱まり、資金調達もパブリック市場からオルタナティブ市場へと広がっています。循環的な要因よりも、構造的な力が市場を動かす比重が高まっています。

こうした環境は、投資家にとって新たな挑戦となります。これまでの株式・債券の枠組みや、パブリック・プライベート市場の組み合わせも十分とはいえません。ポートフォリオの成果は、どの市場にどの程度エクスポージャーを置き、それらをどのように組み合わせるかといった「アクティブな設計」によって、より左右されるようになっています。今後2020年代後半を見据えるうえで重要なのは、持続性のある構造要因を見極め、その相互作用を理解し、資本配分・運用機関選定・ポートフォリオ構築にどう影響するかを明確にすることが不可欠です。

投資環境を形づくる要因はさまざまですが、その中でも特に重要なのが、資産横断的に影響し、ポートフォリオの考え方そのものを変える「5つの構造的な力」です。こうした力が、今後の投資判断とポートフォリオの強靭性を大きく左右すると考えます。

1. AIの優位性と「データ格差」の拡大

ChatGPTの登場は、最も急速に普及した技術革新の一つとなりました。AIの重要性は、単なる技術革新にとどまらず、市場構造そのものに影響を及ぼしています。AIは、投資プロセス、運用機関の差別化、新たな投資機会の創出、という三つの側面で投資の在り方を変えています。

従来、データサイエンスや生成モデルは主にシステマティック運用の領域でしたが、現在では伝統的な運用手法を採用する運用機関でも幅広く導入されています。競争優位性の源泉は、ツールの有無から、データの質や判断そのものへと移行しています。高品質のインプットと専門的な洞察、明確な意思決定フレームワークによって、AIは銘柄選択の精度向上、ポートフォリオ構築の一貫性、構造変化の早期把握に役立っています。

特にプライベート市場では、運用機関の選別に対する重要性が一段と高まっています。パブリック市場と異なり、情報は標準化されておらず透明性も低いため、AIは可視性の向上には役立つものの、判断力と文脈理解については依然として課題が残されています。一貫した市場横断的アプローチを採用する運用機関ほど、長期的な成果を実現しやすい傾向があります。

また、AIは投資機会そのものの形成にも影響を与えています。インフラや関連技術といったAIの要素に関連する重要な投資はプライベート市場から始まり、時間をかけて移行するケースが多く見られます。そのため、AIは単独テーマではなく、ポートフォリオ全体に関わる横断的な検討事項と位置付ける必要があります。

投資家への示唆

AIは単なるベータの配分問題ではなく、運用機関の能力、データ管理体制、ガバナンスを評価するための試金石であり、とりわけ情報が乏しく乖離の大きい領域において重要性が高まっています。

2.分散投資を再定義する新たな視点

分散投資に関する従来の前提は、もはや十分に機能しているとはいえません。インフレ、政策、資産間の相関といった要素が不確実性を増す中で、単純な株式と債券の組み合わせに頼ってバランスを維持することは難しくなっています。そのため、投資家はリスクとリターンの源泉がどこにあるのかを、より意識的に捉える必要があります。

現在の効果的な分散投資には、アクティブ運用とパッシブ運用、システマティックアプローチとファンダメンタルアプローチ、さらにはオルタナティブやプライベート市場といった多様な戦略を組み合わせることが求められます。しかし、選択肢を増やすだけでは十分ではありません。各戦略が果たす役割、ポートフォリオ上での重要度、そして異なる市場環境下でどのような特性を示すのかを丁寧に見極めることが重要です。

Sensitivity to macro shocks

出所:ラッセル・インベストメント

ポートフォリオの運用成果を左右する根本的なリスクを正確に理解することへの重要性はこれまで以上に高まっています。リスク要因は資産クラスや市場を横断して広がっているため、エクスポージャーや相殺、想定外のリスクの偏りの把握と可視化がより必要になっています。

その結果、スリーブ単位での分散ではなく、ポートフォリオ全体としての分散を評価する考え方が重視されるようになっています。リスクがどのように相互作用するかを理解し、市場の局面の変化に応じてエクスポージャーを調整し、必要なタイミングで分散効果を補強する能力が、ポートフォリオの強靭性を左右するようになっています。

投資家への示唆

分散投資は、もはや単なる資産クラスの配分ではなく、意図的な設計であるといえます。適切な配分設定、市場環境の変化に対する認識、継続的なポートフォリオの管理が不可欠です。

3.資金調達と成長機会に対するアクセスの変化

パブリック市場とプライベート市場の境界が曖昧になる中、企業の資金調達手段や、投資家が成長機会にアクセスするルートは大きく変化しています。かつて明確に区分されていた両市場は、いまや、より連続的な「機会の連鎖」 を形成しており、資本は市場と資本構造を横断して流動的に移動するようになっています。特にAIインフラを中心とした資本集約型の分野では、データセンターや電力供給設備、デジタルインフラなどが、まずプライベート資本で資金調達され、その後プライベート・クレジットやストラクチャード商品、公募市場へと進むケースが増えています。

同時に、プライベート市場へのアクセスも拡大し、機関投資家によるプライベート資産への配分比率は拡大しています。新たな投資の枠組みやプラットフォームの登場が、この流れをさらに加速させています。こうした状況では、パブリック市場とプライベート市場を明確に区別することが難しくなり、流動性やエクスポージャーも構造によって変動しやすくなります。

これにより、ポートフォリオ構築の難易度は一段と高まっています。投資家は、各エクスポージャーが リターン、流動性、リスク、そして強靭性の観点でどのように寄与するのか を慎重に判断する必要があります。金利の上昇や規制の変化も相対価値に影響を与えています。プライベート・エクイティでは、レバレッジよりもオペレーションの実行力やセクターに対する専門的な知見がリターンを左右するようになっています。一方、プライベート・クレジットは特に資産担保型やインフラ関連融資において、銀行と並ぶ持続的な資金供給源となっています。実物資産は、環境に応じて上場・非上場を行き来できる柔軟性を提供しています。

市場アクセスの拡大により、リターンが薄まるのではないかとの懸念もあります。しかし、変化が見られているのはアクセスの在り方であり、市場構造が変化にどう対応するか、そして投資家が流動性管理や投資ペースの管理、ポートフォリオ構築の規律をどう保つかが引き続き重要であると考えます。

投資家への示唆

プライベート資産の管理は、リターンの追求だけでなく、統合的な運用と流動性管理が不可欠であると言えます。

4.リテール投資家の存在感の高まり

リテール投資家は、グローバル市場における影響力を急速に高めています。2027年には、富裕層の規模が世界の運用資産の約半分に達するとの見方もあり、その影響は市場構造に大きな変化をもたらしています。

デジタル・ツールの普及により参加障壁が下がり、取引コストの低下と相まって、リテール主体の取引量は増加しています。市場の端的な動きである「フロー」と「センチメント」が短期的な価格形成により大きく影響するようになった背景には、このリテール資金の増勢があります。カスタマイズや税効率へのニーズも高まり、ダイレクト・インデックスや個別最適化されたポートフォリオ・ソリューションの採用が進んでいます。

オプション取引の活発化や、テーマ性の高い株式への資金流入がミーム株の急騰を引き起こし、価格とファンダメンタルの乖離を拡大させた場面も記憶に新しいところです。同様の現象はクレジット市場や新興国市場でも見られ、ETFを通じたリテールの資金が、市場のリスクオン・リスクオフの動きを加速させる局面も生まれています。

リテール投資家の裾野拡大は、2022年末以降の景気回復が不均一となった一因でもあります。株式や住宅を保有する世帯は資産価格の上昇恩恵を受けて消費を維持した一方、そうでない層は引き続き圧力にさらされています。資産価格の動向が消費者マインドに直結する度合いが強まっていることも、マクロ環境を評価するうえで無視できないポイントです。

投資家への示唆

リテール主導のフローは、市場の分散や展開スピードを高めており、流動性の見極め、クオリティや主体的なリスク管理の重要性を一段と押し上げていると考えます。

5.分断が進むグローバル経済・市場環境

地政学や政策の影響力が市場においてかつてないほど高まっています。2025年4月の「解放の日」をきっかけに、世界はこれまでのような同期したグローバルサイクルから離れ、より地域ごとに異なる市場環境へ移行しています。今後、米国・欧州・新興国で主要選挙が相次ぐこともあり、不確実性は引き続き高い状況が続く見込みです。

今の市場環境では、短期的ショックとそれに続く二次的影響、さらに長期的な構造変化を切り分けて考える必要があります。そのためには、長年続いた「ホームカントリーバイアス」から脱することが欠かせません。成長や政策の方向性が地域ごとに乖離する中、単一市場への集中は当然の前提ではなく、積極的に取るリスク選択となっています。

したがって、地理的区分にとらわれるのではなく、インフレ持続性、財政刺激、エネルギー・防衛需要、サプライチェーン再編といった根源的なエクスポージャーに注目する必要があります。その兆候はすでに各地域で見られ始めており、欧州では、財政支援、防衛費増加、産業政策が活動と企業収益を下支え、新興国では、特にテクノロジー推進や改革志向の見られる国々でファンダメンタルが改善、米国では、メガキャップ中心の上昇から、持続的投資をキャッシュフローへと結びつける企業へとリーダーシップが広がりつつあります。

また、リスク管理の在り方も変化しています。政府支出の増大により一部地域ではインフレの不確実性が高まる一方、金融環境の引き締まりが他地域の成長を制約し、資産間の分散を拡大させています。パブリック市場ではセンチメント主導の歪みが生じやすくなり、クレジット市場ではバランスシートの強さによる選別がより鮮明になっています。

こうした課題に対しては、パブリックとプライベートをバランスよく組み合わせることが有効です。資本集約的なテーマは数年単位で進展するため、プライベート・インフラやプライベート・クレジット、エネルギーやデータ、安全保障関連の実物資産に機会が生じています。

投資家への示唆

地域配分は、ますますファクターの再現へと変わりつつあり、為替リスクも含めた柔軟かつ意図的なグローバル分散とが必要です。

転換点

私たちは、投資の世界が大きく変わる希少な転換点を迎えています。長年信頼されてきた分散の効能が弱まる中、ポートフォリオの構築にはこれまで以上に高度な判断が求められています。だからこそ、現投資環境は投資家にとって意味のある局面でもあります。

重要なのは、過去の前提を超えて、将来に適応した強靭なポートフォリオを設計することです。そのためには、リスクへの明確な理解、規律ある運用機関選択、パブリックとプライベート市場を統合したアプローチが不可欠となります。今日どのようにポートフォリオを構築するかは、現投資サイクルを超えて、長期的な成果に影響を与えることになると見ています。

まとめ

投資環境を大きく変えている要因として、次の5つが挙げられます。

  •  AIの優位性と「データ格差」の拡大
  • リスクの把握と可視化を通じた分散投資
  • 資金調達と成長機会に対するアクセスの変化
  • リテール投資家の存在感の高まり
  • グローバル経済・市場環境の分断と深刻化

これらの構造要因が市場構造を変化させ、乖離を拡大させるとともに、運用機関選定、リスク管理、ポートフォリオ構築における主体的な判断の重要性を一段と高めています。

AIは、高度な分析手法へのアクセスを広げる一方で、データ品質、ガバナンス、人間の判断力 を基準とした新たな差別化をもたらしています。競争の源泉は、もはやAIツールそのものではなく、データをどう統合し、文脈を踏まえて判断し、最終的な意思決定へつなげるか にあります。特に情報が断片的で結果のばらつきが大きいプライベート市場では、こうした「判断力」と「データの扱い方」が成果の差をより大きくしています。

1.     従来の株式と債券の関係性は、インフレの変動や政策不確実性の高まりにより、安定した分散効果が見込みにくい状況となっています。現投資環境下において、効果的な分散効果を期待するには、以下を考慮する必要があります。

  • ポートフォリオ全体を通じたリスク要因の把握
  • 戦略的な配分設定
  • 各資産の市場局面別の役割

単純な資産の組み合わせではなく、全体最適の設計が重要となります。

発行体企業は、これまでのように市場を明確に分けて資金調達するのではなく、パブリック市場とプライベート市場を連続した「資本のスペクトラム」として活用するようになっています。とりわけAIインフラのような資本集約型の投資については、プライベート市場で始まり、時間をかけて資本構造の異なる階層を移動していきます(パブリック市場への移行)。この動きにより、以下の重要性が高まっています。

  • 流動性の管理
  • エクスポージャーの統合管理
  • 規律あるポートフォリオ構築

現環境下では、パブリック市場・プライベート市場を横断した一体的な運用が求められています。

       世界経済は、成長性、インフレ、政策の方向性が地域ごとに乖離しており、単一地域への投資集中は、意図的なリスクの選択となるためです。このような環境下では、地理的な配分ではなく、以下のような「根源的なエクスポージャー」に注目することが重要です。

  •  財政政策
  • エネルギー需要
  • 防衛需要
  • サプライチェーンの再編

これらを踏まえながら、パブリック市場とプライベート市場の両方を活用した柔軟なグローバル分散が求められています。
