In the year leading up to March 2023, the Federal Reserve raised short-term interest rates by nearly 5%. Long-term rates rose by 2.5%. The sharp increase had a big impact on the value of bank assets. Banks held $17 trillion of long-term loans and securities with an average duration of about four years. The implied loss on these assets was thus 4 × 0.025 × $17 = $1.7 trillion. Bank equity stood at $2.2 trillion, hence these losses had the potential to wipe out most of the capital of the banking sector.
截至 2023 年 3 月的一年中,美联储将短期利率提高了近 5%。长期利率上升了 2.5%。这一急剧增长对银行资产的价值产生了重大影响。银行持有 17 万亿美元的长期贷款和证券,平均期限约为四年。因此,这些资产的隐含损失为 4 × 0.025 × $17 = $1.7 万亿美元。银行股本为 2.2 万亿美元,因此这些损失可能会消耗掉银行业大部分的资本。
Strikingly, bank investors were unconcerned. The value of bank stocks … held up well and tracked the overall stock market throughout 2022 and early 2023. Bank profits, as captured by their net interest margins, also held up and even rose slightly despite the large maturity mismatch. Evidently, banks had another source of profits supporting their value.
令人惊讶的是,银行投资者并不担心。银行股票的价值表现良好,并在整个 2022 年和 2023 年初与整体股市保持一致。银行利润,如其净利息差所反映的,也保持稳定,甚至略有上升,尽管存在较大的期限错配。显然,银行还有其他利润来源支撑其价值。
That source of profits was deposits. Deposits are special, as reflected in their rates, which are low and insensitive to market rates. This “low beta” makes deposits much more profitable for banks when interest rates rise. Historically, deposit betas have been about 0.4. As a result, when the Fed raised rates banks went from earning 0% to a (1 − 0.4) × 0.05 = 3% spread on deposits. Deposits stood at $17 trillion, so deposit profits rose by $510 billion per year. …
利润的来源是存款。存款是特殊的,这反映在它们的利率上,这些利率较低且对市场利率不敏感。这种“低贝塔”使得当利率上升时,存款对银行来说更加有利可图。历史上,存款贝塔值约为 0.4。因此,当美联储加息时,银行从赚取 0%变为在存款上获得(1 − 0.4) × 0.05 = 3%的利差。存款总额为 17 万亿美元,因此存款利润每年增加 5100 亿美元。…
The bank has deposit market power, which allows it to pay a deposit rate that is low and insensitive to the market interest rate, i.e. its deposit beta is less than one. The bank thus earns a deposit spread that increases with the market rate. This makes its deposit franchise valuable.
银行拥有存款市场势力,这使其能够支付低且对市场利率不敏感的存款利率,即其存款贝塔系数小于一。因此,银行赚取的存款利差随着市场利率的上升而增加。这使得其存款特许经营权具有价值。
When interest rates go up, a bank’s long-term assets (loans, bonds) lose value, which could make the bank insolvent on a mark-to-market basis. (Which actually happened to Silicon Valley Bank in 2023.) Fortunately, the bank has another asset, “the deposit franchise,” whose value goes up when interest rates go up. “The deposit franchise” is just depositors not paying attention to interest rates. That’s what it is! The bank can “pay a deposit rate that is low and insensitive to the market rate.” “Deposit franchise” is a nicer way to put that, and it gestures at the reasons that this funding advantage exists: There’s a “franchise,” the bank has built up customer relationships and brand loyalty, it has branches and tellers and Little League sponsorships, so people leave their money in the bank without fighting for every last basis point of interest.1
当利率上升时,银行的长期资产(贷款、债券)会贬值,这可能会使银行在市值基础上资不抵债。(这实际上发生在 2023 年的硅谷银行。)幸运的是,银行还有另一项资产,“存款特许权”,其价值在利率上升时会上升。“存款特许权”就是存款人不关注利率。这就是它的本质!银行可以“支付一个低且对市场利率不敏感的存款利率。”“存款特许权”是一个更好听的说法,并且暗示了这种资金优势存在的原因:有一个“特许权”,银行建立了客户关系和品牌忠诚度,它有分行、柜员和小联盟赞助,所以人们把钱留在银行里,而不是为每一个基点的利息而争斗。
Again, the paper is titled “Deposit Franchise Runs,” and the point is that this theory is not as true as it used to be. “In this paper,” say Drechsler et al., “we argue that the deposit franchise is a runnable asset, and that this creates fragility when interest rates rise.” (“A new type of bank run,” they call it.) Silicon Valley Bank’s depositors did take a lot of their money out; the value of its deposit franchise evaporated. At least some banks had depositors who were systematically more sensitive to interest rates and their financial condition than bankers (and regulators) would have predicted, causing problems for those banks.
这篇论文题为《存款特许权挤兑》,其观点是这一理论不再像过去那样真实。Drechsler 等人在论文中表示:“我们认为存款特许权是一种可挤兑的资产,这在利率上升时会造成脆弱性。”(他们称之为“一种新型银行挤兑”。)硅谷银行的储户确实提取了大量资金,其存款特许权的价值蒸发了。至少有些银行的储户对利率和其财务状况的敏感性比银行家(和监管者)预测的要高,这给这些银行带来了问题。
小银行的风险更大。
But most banks did fine, and big banks generally did — as traditional theory predicts — have rising profits as rates went up. As rates went up, those banks were able to earn more interest on their assets (by putting money into investments that paid market interest rates) without paying much more interest on their liabilities (by not raising rates on their deposits). Their deposit franchises held up.
但大多数银行表现良好,大型银行通常也表现良好——正如传统理论所预测的那样——随着利率上升,利润也在上升。随着利率上升,这些银行能够通过将资金投入支付市场利率的投资中来赚取更多的资产利息,而无需在负债上支付更多的利息(因为它们没有提高存款利率)。它们的存款业务保持稳定。
Anyway: 无论如何:
[Yesterday], the Consumer Financial Protection Bureau (CFPB) sued Capital One, N.A., and its parent holding company, Capital One Financial Corp., for cheating millions of consumers out of more than $2 billion in interest. The CFPB alleges that Capital One promised consumers that its flagship “360 Savings” account provided one of the nation’s “best” and “highest” interest rates, but the bank froze the interest rate at a low level while rates rose nationwide. Around the same time, Capital One created a virtually identical product, “360 Performance Savings,” that differed from 360 Savings only in that it paid out substantially more in interest—at one point more than 14 times the 360 Savings rate. Capital One did not specifically notify 360 Savings accountholders about the new product, and instead worked to keep them in the dark about these better-paying accounts. The CFPB alleges that Capital One obscured the new product from its 360 Savings accountholders and cost millions of consumers more than $2 billion in lost interest payments.
[昨天],消费者金融保护局 (CFPB) 起诉 Capital One, N.A. 及其母公司 Capital One Financial Corp.,指控其欺骗数百万消费者,导致超过 20 亿美元的利息损失。CFPB 指控 Capital One 向消费者承诺其旗舰产品“360 Savings”账户提供全国“最佳”和“最高”的利率,但银行在全国利率上升时将利率冻结在较低水平。大约在同一时间,Capital One 创建了一个几乎相同的产品“360 Performance Savings”,与 360 Savings 的区别仅在于其支付的利息大幅增加——一度超过 360 Savings 利率的 14 倍。Capital One 并未专门通知 360 Savings 账户持有人有关新产品的信息,而是努力让他们对这些收益更高的账户保持不知情。CFPB 指控 Capital One 向其 360 Savings 账户持有人隐瞒新产品,导致数百万消费者损失超过 20 亿美元的利息收入。
I love it.2 “Capital One did not specifically notify 360 Savings accountholders about the new product.” Imagine! Imagine Capital One calling up all of its depositors earning 0.3% and saying “hey just FYI, we have another product that is basically identical but pays you 4.25%, want to switch?”
我喜欢它。2 “Capital One 并没有特别通知 360 储蓄账户持有人关于新产品的消息。” 想象一下!想象一下 Capital One 给所有赚取 0.3%利息的储户打电话说:“嘿,仅供参考,我们有另一个基本相同但支付 4.25%利息的产品,想要转换吗?”
Oh, fine, that is not actually that hard to imagine. That’s really the minimum you’d expect from an adviser who is looking out for you, just straightforwardly good customer service.
哦,好吧,那其实并不难想象。这真的是你对一个为你着想的顾问的最低期望,只是简单的良好客户服务。
But it’s bad banking! Capital One is not an adviser who is looking out for its depositors! It’s a bank! Its relationship with depositors is “we want to pay you a deposit rate that is low and insensitive to the market rate.” That is the very heart of the relationship. It’s not very nice, for you, if you’re the depositor. But that’s banking, man. If you are a depositor at a bank, you are not so much “a customer” as you are “raw material.” You are valuable to the extent you don’t pay attention. If they went out of their way to pay you a market rate on your deposits, they would not be a bank.
但这就是糟糕的银行业务!Capital One 不是为储户着想的顾问!它是一家银行!它与储户的关系是“我们想给你一个低于市场利率且对市场利率不敏感的存款利率。”这就是关系的核心。如果你是储户,这对你来说不太好。但这就是银行业,伙计。如果你是银行的储户,你与其说是“客户”,不如说是“原材料。”你有价值的程度在于你不注意。如果他们特意给你支付市场利率的存款,他们就不是银行了。
