European central bankers leave Jackson Hole unconvinced by Fed reassurances

ECB President Christine Lagarde has made the durability of this architecture a personal priority since taking office in 2019. She negotiated the 2021 extension that removed expiry dates and added a pricing schedule designed to discourage routine use while guaranteeing availability in stress. That framework, she has argued repeatedly, depends on predictability, the certainty that the Fed will not impose new conditions, caps or political tests when the next shock arrives.

The yen intervention that changed the mood

The specific grievance European officials raised in Jackson Hole was not hypothetical. In April and May 2024, the Bank of Japan intervened in currency markets to support the yen, selling dollars from its reserves. The operation was coordinated with the US Treasury and the Federal Reserve, but the ECB was informed only after the fact. For Frankfurt, the episode was a breach of the informal G7 understanding that major foreign-exchange operations, especially those involving the dollar, are discussed beforehand. The Fed's willingness to accommodate Tokyo without consulting its European partners suggested that the swap-line network's governance had become asymmetric: Washington and Tokyo could act bilaterally, while the euro area was treated as an afterthought.

One European official, speaking on condition of anonymity because the discussions were private, described the 2024 intervention as "a template for how the Fed might handle future crises, bilateral deals with the counterparty that matters most politically, leaving the rest of us to read about it in the markets." The Fed disputes this characterisation, arguing that the yen operation was a Treasury-led FX intervention, not a swap-line drawing, and therefore fell outside the coordination framework.

Backstop meddling and the political overlay

Beyond swap lines, the deeper anxiety concerns the Fed's emergency lending authorities, the "backstops" created under Section 13(3) of the Federal Reserve Act. These facilities, which include the Primary Dealer Credit Facility, the Money Market Mutual Fund Liquidity Facility and the Commercial Paper Funding Facility, were all deployed in 2020 with Treasury backing. They are designed to stabilise US markets, but their effects are global: when the Fed backstops US money funds, it indirectly supports the European banks and insurers that rely on those funds for short-term dollar funding.

European officials worry that a future US administration could attach conditions to Treasury support for such facilities, for example, restricting access to firms from countries deemed non-compliant on sanctions, trade or technology policy. The Fed cannot unilaterally impose such conditions, but it also cannot operate the facilities without Treasury equity. The Jackson Hole discussions reportedly included a direct question: would the Fed commit to opposing any political conditionality on backstop access? The answer, according to sources, was a careful non-denial, the Fed would "follow the law" but would not pre-judge hypothetical congressional or executive actions.

Institutional memory and the 2011 precedent

The current unease has a precedent. In 2011, as the euro-area sovereign debt crisis deepened, the Fed temporarily expanded its swap lines with the ECB and other central banks. The move was widely credited with preventing a dollar-funding collapse at European banks. But the decision was taken unilaterally by the Fed, without a formal governance structure, and some European policymakers felt the communication was opaque. The 2013 standing-arrangement agreement was meant to fix that. Thirteen years later, the Europeans fear the fix is fraying.

The Bank for International Settlements, which hosts the regular meetings of the Global Economy Meeting and the Markets Committee in Basel, has long served as the forum for technical coordination. But the BIS has no authority over the Fed's statutory decisions. Its role is to facilitate information exchange, not to enforce commitments. European officials have floated the idea of a more formalised "swap-line charter", a memorandum of understanding that would codify notice periods, pricing transparency and dispute resolution. The Fed has so far resisted, preferring the flexibility of the current arrangement.

The domestic constraints on both sides

The Fed's reluctance to bind itself is not purely strategic. The Federal Reserve Act gives the Board of Governors broad discretion over emergency lending, but that discretion is exercised under intense congressional scrutiny. Since 2020, Republican lawmakers have criticised the Fed for "bailing out foreign banks" through swap lines, a mischaracterisation, since the loans are fully collateralised and carry penalty-rate pricing, but one that resonates politically. Any formal treaty-like commitment would require congressional approval, which is currently unobtainable. The Fed's lawyers have advised that even a non-binding MOU could be cited in future hearings as evidence of overreach.

On the European side, the ECB faces its own constraints. The Treaty on the Functioning of the European Union prohibits monetary financing of governments, and the swap lines are carefully structured to avoid that classification. But the ECB's Governing Council includes governors from 20 national central banks, each with domestic political sensitivities. A perception that the ECB has ceded too much autonomy to the Fed would be politically toxic in several capitals. Lagarde's push for formalisation is partly about protecting the ECB's institutional credibility at home.

What the markets are pricing

So far, financial markets have not priced in a breakdown of the swap-line framework. Cross-currency basis swaps, the market measure of dollar-funding stress for euro-area banks, remain narrow, with the one-year euro/dollar basis trading around minus 12 basis points in late August, well within the range seen since 2021. But market participants note that the basis widened sharply during the March 2023 banking turmoil, when Silicon Valley Bank's failure triggered a flight to dollars. The ECB drew $2.3 billion on its swap line that week, a modest amount but a signal that the facility remains operationally vital.

If the Jackson Hole mood is any guide, the next stress episode will test more than plumbing. It will test whether the informal understandings that have underpinned central-bank cooperation for three decades can survive a world where monetary policy is increasingly entangled with geopolitics, industrial policy and great-power competition. The Fed's reassurances this week were sincere, according to the Europeans who heard them. They were also, in the final analysis, unenforceable.

The October deadline

The next meaningful checkpoint is the G20 finance ministers and central bank governors meeting scheduled for 24-25 October in Washington, held alongside the IMF-World Bank annual meetings. That gathering will produce a communiqué, usually anodyne, but this year likely to contain language on "central bank cooperation" and "global financial safety net" that will be parsed for nuance. European officials have indicated they will push for a paragraph explicitly reaffirming the swap-line network's standing nature and calling for "advance consultation on significant foreign-exchange operations." Whether the US Treasury and Fed agree to that language will be the first real test of whether Jackson Hole's conversation changed anything.
