Sight Deposits and CHF Intervention Signals

Every Thursday morning at 09:00 CET, the Swiss National Bank quietly releases a number that FX traders watch as closely as any policy rate decision: the weekly total of sight deposits held by domestic banks at the SNB. The number itself looks mundane — a balance sheet line item measured in billions of Swiss francs. What it reveals is anything but. Sight deposits are the SNB's operational fingerprint. When they rise sharply, the SNB has been buying foreign currency, flooding the Swiss banking system with newly created CHF. When they hold steady or fall, the SNB is standing aside.

No other central bank in the G10 uses its balance sheet so visibly and so deliberately as a primary FX intervention tool. For CHF traders, the weekly sight deposit release is a near-real-time intervention signal that turns an otherwise opaque operation into a traceable, quantifiable event.

视觉存储是什么,为什么它们是独特的

当国家央行干预外汇市场时,购买欧元,美元或其他外汇以削弱瑞士法郎,它通过直接将瑞士弗朗克存款存入国内商业银行在央行持有的储备账户来支付该外汇. 视线存款截至目前,瑞士银行在瑞士的银行存款中使用的货币是:

The mechanics are straightforward. The SNB buys, say, EUR 10 billion in the interbank FX market. To pay for those euros, it creates CHF 10 billion and credits the counterparty banks' accounts at the SNB. Total sight deposits rise by roughly that amount. The foreign currency purchased goes into the SNB's reserve portfolio, and the newly created francs sit in the domestic banking system as reserves. Sight deposits are therefore a direct, near-real-time record of the Swiss franc the SNB has injected into the financial system through FX operations.

这种透明度在很大程度上是偶然的,是SNB每周汇报资产负债表的产物.但它已经成为SNB市场活动最密切关注的指标,

历史景观:三个国家银行活动时期

了解目前的视线存款水平需要了解之前的情况.过去15年中,该系列经历了三个不同的制度,每个都与SNB外汇政策的不同阶段相关.

Era 1: The EUR/CHF Floor (2011–2015)

The most aggressive phase of SNB FX intervention began in September 2011, when the SNB announced a minimum exchange rate floor of 1.20 for EUR/CHF. The floor was a unilateral commitment to prevent any further CHF appreciation below that level. To defend it, the SNB had to stand ready to buy unlimited quantities of foreign currency — primarily euros — whenever EUR/CHF threatened to fall below 1.20.

Over the three-and-a-half years the floor was in effect, sight deposits expanded from roughly CHF 30 billion to over CHF 300 billion, a tenfold increase. By early 2015 the SNB's balance sheet had grown to the equivalent of more than 80% of Swiss GDP — extraordinary by any international comparison. The deposit accumulation was essentially an accounting identity: every euro the SNB bought to defend the floor appeared as a corresponding CHF credit in the domestic banking system.

Era 2: The 2015 Shock and Its Aftermath

On 15 January 2015, the SNB abruptly removed the EUR/CHF floor without warning — a decision that sent shockwaves through global FX markets. EUR/CHF fell nearly 20% in minutes, one of the largest single-day moves in a major currency pair since the floating rate era began. Sight deposits, which had reached roughly CHF 320 billion at the time, did not immediately decline — the CHF that had been created during the floor era remained in the system regardless of the policy change.

In the years following, sight deposits drifted modestly higher and then largely plateaued through 2018–2019 around CHF 540–580 billion, reflecting continued but more modest intervention activity as the SNB worked to prevent the franc from becoming "highly valued" — the phrase the SNB uses to justify discretionary FX purchases even without a formal floor. The SNB also deployed negative interest rates (–0.75% on sight deposit balances above exemption thresholds) to discourage speculative franc inflows, adding an interest rate disincentive to the FX toolkit.

时代3:COVID,通货膨胀和2022年的转向

The COVID-19 crisis in 2020 triggered another wave of safe-haven inflows into CHF, pushing EUR/CHF dangerously close to the 1.05 range. The SNB responded with aggressive FX purchases, and sight deposits surged from around CHF 580 billion to over CHF 720 billion by mid-2021 — a CHF 140 billion expansion in roughly 18 months. At its peak, the SNB's reserve portfolio exceeded CHF 1 trillion, an amount larger than Swiss GDP.

The regime shifted again in 2022. As global inflation surged, the SNB reversed its intervention stance. Rather than weakening the franc, it began allowing or even encouraging CHF appreciation as a tool to reduce imported inflation — a complete reversal of the prior decade's posture. Sight deposits began to decline as the SNB stopped buying foreign currency and, in some periods, sold it. The policy rate moved out of negative territory in June 2022 for the first time since 2014.

阅读每周号:商家们关注的内容

视觉存款的实际挑战是分离信号和噪音.该系列每周都会波动,因为并非所有波动都反映了外汇干预短期流动性管理,季节性因素和国内信贷操作可能导致适度的变化.以下框架帮助交易者确定哪些变化是有意义的.

干预值框架

• Weekly change under CHF 2–3 billion: 正常运营变化.没有干预信号.背景流动性管理和复购操作可以解释这些动作.
• Weekly change of CHF 3–8 billion: 模糊区.需要更密切关注,特别是如果欧元/瑞郎走向国家央行敏感度水平. 查看欧元 /瑞郎当前行为在同一周的确认.
• Weekly change above CHF 8–10 billion: Strong intervention signal, particularly if it coincides with EUR/CHF stress, global risk-off events, or CHF approaching "highly valued" territory by SNB assessment standards. During the COVID surge, weekly increases reached CHF 10–20 billion in peak stress periods.
• 持续的每周下降: Signals the SNB is either selling FX reserves or running down the balance sheet. Associated with the 2022 inflation-driven CHF-supportive regime.

汇率存款与欧元/瑞郎的相关性

货币交易者对欧元/瑞郎的交易是主要分析框架.在防范性干预制度下,当国家央行试图防止瑞郎增长时,相关性是负面的:当欧元和瑞郎汇率下降 (瑞郎加强) 时,随着国家央行的购买欧元,货币汇率往往会上升.当欧美汇率稳定或恢复时,存款积累的速度会放缓.

期货存款,国家央行资产负债表和外汇储备

期货存款是SNB外汇干预的国内负债方面.资产方面的对应是外汇储备组合SNB随着时间的推移购买的累积欧元,美元,英和日元.跟踪这一余额的两侧可以更丰富地了解SNB的整体能力和承诺.

瑞士国家银行外汇储备组合在高峰时期超过了1万亿瑞士法郎,是世界上相对于GDP规模最大的.瑞士国立银行主要投资这些储备在高档政府债券和股票中.

政策利率联系:作为干预补充的负利率

期货存款与国家央行政策利率不分离存在.在2015~2022年期间,国家央行的期货押金比期存款超过豁免门的利率是负.目的是两方面的:阻止投机性入汇瑞郎 (使持有法郎变得昂贵),并通过使过剩储备成为银行系统产生收益的位置而不是产生收利的位置,降低资产负债扩张的成本.

负期存款利率创造了一个反循环,加强了外汇干预战略.从SNB外汇购买中获得CHF的银行面临持有这些法郎的直接成本,鼓励其在其他地方部署流动性,最好是瑞士以外,这本身会对法郎施加轻微的值压力.无限的外汇买入能力和收益负利率的结合是SNB十年来独特的政策尾酒.

What CHF Traders Should Watch in 2025–2026

The SNB completed an easing cycle through 2024–2025, bringing the policy rate down from 1.75% to around 0.25–0.50% as inflation returned to the 0–2% target. With rates near zero again, the SNB is closer to the boundary where negative rates become a policy option once more — and by extension, where the FX intervention toolkit could be reactivated more aggressively.

必须监测的关键紧张:

• 欧元/瑞郎方向: A sustained EUR/CHF decline toward 0.92–0.93 historically triggers intervention discussion. The SNB has not articulated an explicit floor since 2015, but its quarterly assessments consistently reference exchange rate valuation as a policy input.
• 全球风险事件: 瑞方是首要的避险货币,与日元和黄金一起.任何重大全球压力事件地缘政治冲击,金融市场混乱或衰退恐惧往往会产生瑞方的流入,SNB可能需要对抗.在任何重大风险事件发生后一周内,视觉存款释放是关键的.
• 通货膨胀差异: 如果瑞士通胀率进一步低于欧元区通胀,则容忍或鼓励瑞士法郎升值的理由会减弱.相反,如果欧元地区通胀再次加速,升值瑞士的法郎将给瑞士提供相对价格优势,而瑞士国家银行可能不那么有动力抑制这一优势.
• 资产负债表容量: 国民银行外汇储备组合从2021年的峰值逐渐下降. 其他资产 数据可以让人了解国家银行是否正在积极消耗投资组合,还是仅仅通过估值影响让其缩小.
