Scottish Central Bank needed on day one of independence, report urges

An independent Scotland must establish a tailored central bank from day one of secession rather than relying on transitional arrangements tied to the Bank of England, a major new macroeconomic report urges.

According to a paper published by William Thomson and Warren Mosler, available via The National, copying the Bank of England or relying on sterling during a transition period is fundamentally flawed. The authors argue that modern central banks are weighed down by bloated liabilities generated after financial crises and face redundant toolkits when combating inflation driven by global conflict and climate change. Instead, the paper contends that a democratic Scottish Central Bank should focus on full employment, reducing inequality, and directing resources to the real economy.

This perspective contrasts directly with official Gov proposals. The Scottish Government outlines a two-phase currency approach following independence. During phase one, Scotland would continue to use the pound sterling to ensure continuity for households and businesses while avoiding immediate redenomination hurdles. An independent Scottish Central Bank would be established on day one to oversee financial stability and monitor economic conditions before advising on the eventual introduction of a separate Scottish pound in phase two.

Independent economic analysis highlights the severe trade-offs inherent in these currency pathways. As detailed by the Economics Observatory, maintaining a fixed exchange rate or informal sterlingisation while running a structural fiscal deficit and a current account deficit creates acute macroeconomic pressures.

The debate over the correct monetary architecture for an independent Scotland touches on deep historical divisions over currency and sovereignty. During earlier constitutional discussions, such as the Sustainable Growth Commission recommendations, proposals suggested that monetary policy should remain under the control of the Bank of England while an independent Scotland took time to phase out sterling. More recent government publications have shortened this timeline slightly, yet the fundamental premise of retaining the Bank of England as the operational central bank for a transitional period of several years remains central to official policy.

Critics argue that keeping the Bank of England in this operational role creates an untenable paradox. Thomson and Mosler point out that under current transitional plans, the Scottish Central Bank would supposedly have oversight of economic conditions and financial stability while having no actual control over base interest rates, note issuance, or the primary lender of last resort mechanisms. In practice, they argue, true financial stability can only be guaranteed by the combined apparatus of the UK Treasury and the Bank of England. This leaves planners with a difficult question regarding whether a framework that relies entirely on an external, unelected institution can genuinely be described as a plan for independence.

Furthermore, modern central banking faces severe structural criticisms from macroeconomic analysts across Europe. Thomson and Mosler highlight that institutions like the Bank of England have become weighted down by massive liabilities created following the global financial crisis and the coronavirus pandemic. To illustrate this expansion, the Bank of England's liabilities rose from significantly lower levels in earlier decades to nearly £750bn, requiring substantial interest payments on hundreds of billions of pounds in commercial bank reserves. Consequently, critics contend that tying a newly independent nation to such an inflated institution is counterproductive when alternative European models, such as tiered reserve systems used by the Swiss National Bank or the Riksbank, offer different paths forward.

The Economics Observatory adds that any choice of currency regime must confront the underlying macroeconomic fundamentals of an independent Scotland, particularly its fiscal and balance of payments positions. Official data indicates that Scotland runs a structural fiscal deficit where public spending exceeds generated tax revenues, alongside a substantial current account deficit. Under an informal sterlingisation model, a persistent current account deficit would drain foreign exchange reserves out of the domestic economy. Because an independent Scottish central bank under such a model would possess only limited and finite reserves, it would face severe constraints in attempting to defend the currency peg or act effectively as a lender of last resort.

Alternatively, establishing a formal monetary union with the rest of the UK would secure the backing of the Bank of England for the Scottish banking sector, but this would impose strict limits on domestic fiscal policy autonomy. Adopting a floating Scottish pound from the outset avoids the trap of reserve drains and allows exchange rates to act as a shock absorber against external economic disruptions. However, as economic commentators note, a free float introduces immediate redenomination challenges, transaction costs, and potential currency depreciation that would affect everything from household mortgages to sovereign borrowing costs.

As political focus shifts toward upcoming electoral cycles, these economic arguments intersect directly with changing parliamentary dynamics. According to projections from polling experts, future electoral outcomes could return a significant block of pro-independence MSPs to Holyrood alongside strong representation from smaller parties like the Greens. Such legislative configurations ensure that constitutional reform, fiscal strategy, and the mechanics of central banking will remain at the forefront of political debate. Observers will monitor how the Scottish Government responds to these mounting economic critiques as policymakers attempt to balance transitional pragmatism against demands for immediate monetary sovereignty.
