Central Banks Navigate Rate Cuts Amidst Balancing Act on Balance Sheets

Central Banks Navigate Rate Cuts Amidst Balancing Act on Balance Sheets 

Central banks are currently under scrutiny, particularly regarding interest rates. Both the Federal Reserve (Fed) and the European Central Bank (ECB) are expected to align with predictions of rate cuts in June, while the Bank of Japan (BoJ) seems poised to initiate steps towards normalization. However, central bank balance sheets loom in the background. The Fed's balance sheet has been diminishing over time, contrasting with the BoJ's substantial balance sheet, which shows no immediate signs of reduction. Additionally, the ECB has been downsizing its balance sheet and recently outlined the principles guiding its policy framework, affecting the size of its long-term balance sheet.

Market participants often seek insights from central bank balance sheets regarding policy decisions, liquidity, and signals. Our global economics team has compiled a document called "The Great Unwind," detailing the next steps for central bank balance sheets. We have identified four key observations:

Quantitative Tightening (QT) differs from Quantitative Easing (QE). While QE aims to ease financial conditions during economic stress and lower long-term rates, QT continues even amidst considerations of rate cuts. QT involves passive actions, with federal debt issuance replacing maturing central bank holdings. Central banks are not signaling a change in policy through QT, and the process is generally absorbed smoothly by the market.

Central bank balance sheets vary across economies. Each central bank tailors its approach to local conditions. For example, the US, with a capital markets-focused economy, expanded its balance sheet through purchases of Treasuries and Mortgage-Backed Securities (MBS). In contrast, the euro area, which relies more on banks, utilized targeted longer-term refinancing operations (TLTROs) to fund banks directly. Therefore, the composition of their balance sheets differs, leading to varying implications during QT.

Central banks can incur losses. As central bank assets increase, so do their liabilities. Fixed coupon payments on assets contrast with rising liability costs due to policy rate changes. This has resulted in negative net income, particularly for the Fed and ECB. While central bank profit and loss statements generally lack macroeconomic implications, political considerations may arise over time.

Balance sheets will contract but not return to pre-crisis levels. Larger balance sheets are now considered the norm, with both the Fed and ECB adopting "floor systems" in their plans. While central bank balance sheets are expected to shrink, they will not revert to pre-global financial crisis levels.

Quantitative Easing (QE) has been a significant aspect of monetary policy during crises, including the global financial crisis and the response to Covid-19. However, the correlation between central bank balance sheet size and asset prices is not stable, and any existing link is unclear. Therefore, rather than focusing on correlations, it is essential to understand the mechanics behind central bank actions.
