Latest / The European Economy Podcast with Fexingo: ECB, Eurozone, and Continental Markets / Why Eurozone Banks Are Sitting on Unrealized Bond Losses
Transcript
- Lucas: So, you know how we've been talking a lot about the eurozone economy feeling surprisingly resilient – GDP growth holding up, the euro steady against the dollar. But there's something lurking underneath that I think is worth pulling on: the unrealized losses on the bond portfolios of eurozone banks. And I don't mean small potatoes – we're talking hundreds of billions of euros in aggregate. Luna: Unrealized losses – that sounds like one of those accounting things that's technically bad but doesn't actually happen unless something forces it, right? Lucas: Exactly. These are paper losses – the difference between what a bond is worth on paper today and what the bank paid for it. If the bank holds the bond to maturity, it gets its money back. The problem is if they're forced to sell early, or if the losses get so big that they eat into capital buffers. Luna: And that's the thing – how big are these losses right now? Like, in the eurozone specifically? Lucas: Well, the European Central Bank has been publishing data on this, and as of the end of last year, the aggregate unrealized losses on securities held by eurozone banks were estimated at around 400 billion euros. That's not nothing. And a big chunk of that is in government bonds – Italian, German, Spanish – because of all the quantitative easing that happened during the negative rate era. Luna: Four hundred billion. That's roughly the size of the entire Greek economy, isn't it? Lucas: It's about twice the size of Greece's GDP, actually. And what makes it particularly tricky is that banks are allowed to use this accounting trick called 'held to maturity' – they can classify bonds as held to maturity and not mark them to market every quarter. So as long as they hold them, the losses stay hidden – they don't hit their reported earnings. Luna: But if they need to sell – say they need liquidity or there's a run or something – then the losses become real, and it hits their capital. Lucas: Right. And that's the fear regulators have been circling. Because if interest rates spike – maybe the ECB has to reverse course on cuts, or inflation surprises – bond prices fall further, and those losses get bigger. Then if banks have to sell, they could eat through their capital buffers. That could tighten lending and slow the economy. Luna: So we're talking about a risk that's been building for years, but it's only if something breaks that it actually hurts. Lucas: Exactly. And the ECB is aware of this. They've been running stress tests – the latest one, in 2025, showed that the system could withstand a severe shock, but that the losses would be significant. And they're also nudging banks to build up capital buffers, especially the ones with big bond portfolios. Luna: But I'm guessing there's a political element too. Because if you force banks to recognize losses, that could hurt their lending to the real economy, and that's something governments don't want before an election. Lucas: You're spot on. It's a classic 'kick the can down the road' scenario. But the longer you wait, the bigger the can gets. And there's also a distribution issue – it's not uniform across the eurozone. German and Dutch banks have relatively smaller losses, while Italian and Spanish banks have larger ones as a percentage of their assets, because they hold more domestic government bonds. Luna: So it kind of exacerbates that north-south divide we've talked about before. Lucas: Exactly. And that's a concern because if Italy's banks are more vulnerable, and they hold a lot of Italian government debt, there's a potential doom loop – the banks and the sovereign become intertwined. If the banks get into trouble, they might need a bailout, which puts more pressure on the sovereign, which then makes the bonds worth even less. Luna: But in the current environment, with the ECB starting to cut rates – they've done a couple of cuts already this year – you'd think bond yields would be coming down, which would actually help bank portfolios, right? I mean, if rates fall, bond prices rise, and those unrealized losses shrink. Lucas: Right, and that's the counterintuitive part. The ECB has cut its deposit rate from 2.5 percent down to 2 percent so far in 2026, and that should help – it means yields on new bonds are lower, but the bonds banks already hold were bought at even lower yields during the QE era. The problem is that longer-term yields haven't fallen as much as the short-term policy rate. In fact, ten-year German bund yields are still above two percent, and Italian BTPs are around three and a half. So the losses are still there – they've just stopped getting worse. Luna: So it's more like a slow bleed rather than a quick fix. Lucas: Yes, and the slow bleed is something the banks can manage. But if something unexpected happens – an inflation shock, a geopolitical event that spikes yields – then the bleed becomes a gusher. And that's why the ECB is walking a tightrope with its rate cuts. They want to support growth, but they also don't want to see a repeat of the 2022 gilt crisis, just in the eurozone. Luna: That's a good point. And we saw in the UK how quickly that kind of thing can spiral – the pension funds and LDI strategies forced to sell, and the BoE had to step in. In the eurozone, who would step in if banks start selling? Lucas: Well, the ECB has several tools. They could do targeted long-term refinancing operations – basically cheap loans to banks – or they could resume some kind of bond buying. But that's not a decision they'd take lightly, because it would feel like a bailout and could create moral hazard. Luna: Moral hazard – banks take on risk, knowing the central bank will bail them out. Lucas: Exactly. And there's also the issue of the new Basel III rules coming into effect in 2027, which require banks to hold more capital against their bond portfolios. That's going to make it more expensive for them to hold those bonds, which might encourage them to sell gradually, but that will take time. Luna: So in a way, the system is kind of frozen – banks can't sell without realizing losses, so they hold on and hope rates come down, but they're not necessarily positioning for a future where rates stay higher for longer. Lucas: Right. And this is where the broader economic context matters. We've got a U.S. economy that slowed to 1.5 percent GDP growth in Q2, and inflation is still above target – core inflation at 3.3 percent. That's not exactly a supportive environment for aggressive rate cuts globally. And with the dollar index still strong at around 120, the euro is only at 1.14, which is okay but not great for eurozone exporters. Luna: So the pressure on the ECB is to keep rates higher for longer, which just prolongs the pain for banks. Lucas: It's a delicate balance. And the thing is, these losses are not just a banking problem – they ripple through the economy. If banks are worried about their capital, they tighten lending standards, and that hurts small businesses and households. That's how a hidden balance-sheet issue becomes a real economic drag. Luna: And it's not just banks – you've got insurance companies and pension funds in the eurozone holding similar bonds, so the exposure is systemic. Lucas: Yes, but banks are the ones we care about because they're the conduit for credit. And that's why the ECB is monitoring this so closely. They've flagged it in their financial stability review – they use the phrase 'vulnerability' a lot. But they also think the system is resilient enough to absorb the losses as long as there's no sudden shock. Luna: So the question is, how long can this balancing act last? And what happens if China's slowdown – which we're seeing in the factory activity data – spills over to Europe and causes a deflationary shock? That could actually push yields down, which would help banks, but it would also hurt growth. Lucas: Right, there's no clean scenario. And that's what makes this such a fascinating – and slightly scary – time to be watching the eurozone banking sector. It's not that the sky is falling, but there's a lot of underlying fragility that isn't in the headlines. Luna: And in a way, that's what we do on this show – we try to look at the things that are hidden in plain sight. Lucas: Exactly. And if you appreciate that kind of approach, you might consider supporting the show. We're independent and ad-free, and a small contribution from listeners like you goes a long way to keeping it that way. You can do that at buy me a coffee dot com slash fexingo – no pressure, just if you find value in what we do. Luna: Yeah, we don't have a huge team, so every bit helps. Now, back to those bond losses – you mentioned the Basel III rules. Do you think banks will proactively shrink their portfolios before 2027, or will they wait and see? Lucas: I think a lot of them are waiting, because they hope rates will come down enough to make those losses manageable. But if yields stay where they are, they'll have to make some tough decisions. Some banks are already reducing their bond holdings in the 'available for sale' category, but the held to maturity ones are still sitting there. Luna: So there's this slow motion game of chicken between the banks and the central bank. Lucas: Exactly. And the outcome matters not just for the banking sector, but for the whole eurozone economy. If we see a wave of bond sales, that could push yields up, which would hurt governments' borrowing costs and potentially undermine the recovery. It's a risk that's easy to ignore when things are going well, but it's one we should keep an eye on. Luna: Well, I'll be watching, and I'm sure our listeners will too. Thanks for breaking it down, Lucas. Lucas: Always a pleasure. And remember, the economy is never as simple as the headlines suggest. Until next time.
