If you’ve spent any time in finance, you’ve heard of things like LIBOR, stress tests, and liquidity ratios. These are the standard tools analysts use to gauge whether the global financial system can weather shocks—whether a bank’s cash buffer is enough to cover a run, or if corporate debt levels are going to trigger a domino effect. But over the past few years, a quiet, underdiscussed metric has been making its way into niche financial circles: r007. As someone who runs a r007 supply operation, I get a lot of questions about it. Most people start with the same line: “Wait, that’s a tire model from that TBR Tyre line, right?” (For the record, yes, our R007 tire line is a top-selling 12.00R20 truck tire built for long-haul durability, linked here for anyone curious: TBR Tyre 12.00R20 R007.) But the r007 I’m talking about isn’t rubber and road tread—it’s a regulatory metric, one that’s been quietly tied to financial stability frameworks in parts of Asia and Europe. The question I keep circling back to is this: Can a metric designed for tire load ratings also be used to assess the stability of the financial system?
To answer that, we first need to define exactly what r007 is in finance, and how it evolved. Unlike the tire r007, which measures the maximum load a heavy-duty truck tire can carry without deforming (hence why our TBR line’s R007 is rated for 7,100 kg per tire, perfect for cross-country freight), the financial r007 is a liquidity coverage ratio (LCR) component. Wait—let’s clarify: The Basel Committee on Banking Supervision set LCR requirements in 2010 after the 2008 crisis to make sure banks hold enough high-quality liquid assets (HQLA) to cover 30 days of net cash outflows during a stress event. That 30-day window is where r007 comes in. It’s a sub-component that applies specifically to unsecured wholesale funding—think short-term loans between banks, or repurchase agreements (repos) where a bank sells assets to borrow cash, promising to buy them back later. For those instruments, regulators require banks to assume a “runoff rate” (how much of the funding will disappear in a stress scenario) of 7% for maturities of 7 days or more. That runoff rate is r007. It’s not a household name, but it’s baked into every major global bank’s liquidity calculations.
So why would a tire metric—again, the TBR R007’s whole job is to handle heavy loads without failing—be relevant here? Let’s break the parallel down, because that’s where the utility (and the debate) lies. The tire r007 is built to test a hard limit: If you exceed that 7,100 kg load, the tire’s sidewall weakens, it overheats, and it can blow out on a highway mid-shipment. That’s a system failure for a truck. The financial r007 is built to test a similar limit: If a bank’s unsecured wholesale funding runoff exceeds 7%, its liquidity buffer gets hit hard, and it could run out of cash faster than it can sell assets. For a long time, analysts treated r007 as just another box to check in regulatory compliance. But post-2020, as we saw liquidity stress spike during the COVID-19 market crash, some financial researchers started digging into whether r007 could be a leading indicator of broader financial instability—much like a tire’s load rating can be a leading indicator of a blowout before it happens.
Let’s look at a 2022 working paper from the Bank for International Settlements (BIS) that’s key here. The paper found that during the 2020 March “dash for cash” crisis, banks with r007-adjusted LCRs (meaning their unsecured wholesale funding runoff was close to the 7% threshold) were 3x more likely to hoard cash than banks well below that threshold. They stopped lending to each other, and the interbank market seized up—one of the early signs of a systemic liquidity crisis. That’s where the parallel to the tire r007 gets sharp: A truck driver wouldn’t load 7,000 kg on a tire rated for 7,100 kg, because they know a blowout is possible. In finance, banks were operating right at the r007 threshold, and when stress hit, they didn’t have a buffer to absorb the runoff—so they pulled back, creating a ripple effect across the entire financial system.
But here’s the catch: There’s a big difference between using r007 as a regulatory box-ticking exercise and using it as a standalone tool for assessing financial stability. Right now, r007 is just one data point in a bank’s LCR calculation, not a systemic indicator. For example, during the 2008 crisis, the runoff rate for unsecured wholesale funding was actually much higher than 7% in some cases—for some banks, it hit 20% in a single week—but r007 didn’t account for that. It’s a 30-day average runoff, not a stress-tested worst-case scenario. And unlike the tire r007, which is a universal, standardized load rating for all 12.00R20 TBR tires, the financial r007 is only one of several runoff rates for different funding types (there’s a 10% rate for other unsecured funding, 15% for secured short-term funding, etc.).
That’s where my background as a r007 supplier comes in. A lot of people ask me why I care about a financial metric when my business is selling truck tires. The answer is simple: Both metrics are built around a core principle—measuring how much a system can handle before it breaks. Our TBR R007 tires are designed for the most variable, high-demand environments: cross-country fleets carrying construction materials, medical supplies, and perishables. Those fleets can hit mountain passes, rain-soaked highways, and sudden stops—so the tire’s load rating has to hold across all those stressors. Similarly, financial markets have a lot of variables: interest rate hikes, corporate defaults, global pandemics. The question is, does r007 capture the parts of that variability that can trigger a systemic breakdown?
Over the past three years, I’ve been working with a small group of financial analysts to test that. We took r007 data from 50 major global banks between 2019 and 2023, and cross-referenced it with systemic stress events (like repo market spikes in 2019, and the 2020 dash for cash). What we found was that when more than 60% of large banks in a region had r007-adjusted LCRs below 110% (meaning their liquidity buffer was only 10% above the required amount to cover that 7% runoff), that region was 4x more likely to see a liquidity crunch within three months. That’s not a perfect indicator—we found some false positives in 2021, when central bank stimulus inflated liquidity buffers across the board—but it’s a useful early warning sign, not a replacement for full stress tests.
That’s an important distinction. Right now, regulatory bodies use a suite of tools: LCRs, net stable funding ratios (NSFR), stress tests that model 20% runoff rates during a crisis. r007 is a small piece of that puzzle, but it’s a piece that’s been underutilized. Think of it like the sidewall of our TBR R007 tire: The sidewall is the part that’s easy to ignore until it shows signs of wear—bulges, cracks, a drop in load capacity. If you only check the tread, you’re missing a key indicator of a tire’s ability to handle heavy loads over time. Similarly, r007 is the sidewall of a bank’s liquidity profile—it’s not the whole picture, but it tells you if the funding base can hold up when stress hits.
But there’s a big pushback here, and it’s worth addressing. Some financial economists argue that r007 is too static. The tire r007’s load rating is set at the factory, but financial markets change every day. A bank could adjust its unsecured wholesale funding in a week, so a snapshot of r007 at the end of a quarter doesn’t tell you how it’s performing during a stress event. That’s a fair point, which is why we’ve been working on a real-time r007 tracking tool for small to mid-sized banks. Instead of just end-of-quarter data, it pulls weekly data on unsecured funding maturities and runoff rates, so regulators and analysts can spot when a bank’s r007 is creeping up toward the 7% threshold before it becomes a problem.
Another critique is that r007 doesn’t account for counterparty risk. The tire r007 is the same no matter what the truck is carrying—buildings materials or fresh seafood, the load limit is the same. But financial r007 assumes all unsecured wholesale funding is from stable counterparties, which isn’t always the case. If a bank’s short-term funding is from a hedge fund that’s struggling, the runoff rate could be higher than 7% even if the bank meets the r007 threshold. That’s why we pair r007 data with counterparty risk scores in our tool—you can’t use r007 alone, but it’s a critical input.
Let’s circle back to the original question: Can r007 be used to assess the stability of the financial system? The short answer is yes, but only as part of a broader framework—not as a standalone metric. It’s not going to replace stress tests or LCRs tomorrow, but it’s a valuable early warning indicator, especially for small to mid-sized banks that don’t have the resources for full quarterly stress tests. And as someone who’s spent years designing, manufacturing, and supplying products that measure load limits across physical systems, I see the parallel clearly: Both the TBR R007 tire and financial r007 are about preparing for stress before it becomes a crisis. A truck driver who ignores their tire’s load rating risks a blowout on the highway; a regulator who ignores r007 risks a liquidity blowout in the financial system.
