Make investments lengthy, borrow brief and leverage up as a lot as potential. That’s the strategy to generate profits in finance. It’s how banks have at all times made their dwelling. However we additionally know very nicely that this story can finish in panic-stricken runs for the exit and monetary crises. That’s what occurred within the nice monetary disaster (GFC) of 2007-09. Since then, because the Financial institution for Worldwide Settlements explains in its latest Annual Economic Report, the monetary system has modified an excellent deal. However this central attribute has not.
Furthermore, notes Hyun Song Shin, financial adviser to the BIS, “regardless of the fragmentation of the actual financial system, the financial and monetary system is now extra tightly linked than ever”. If this feels like an accident ready to occur, you might be fairly proper. Central banks have to be ready to trip to the rescue.
The story the BIS tells is an intriguing one. Thus, the aftermath of the GFC didn’t make the system basically totally different. It simply modified who was concerned. Within the run-up to the disaster, the dominant type of lending was to the non-public sector, significantly within the type of mortgages. Afterwards, lending to the non-public sector levelled off, whereas credit score to governments exploded. The pandemic accelerated that tendency.
That was not shocking: if individuals need to save and lend, another person has to borrow and spend. That’s macroeconomics 101. Along with the change in path got here a change in intermediaries: rather than the large banks have come world portfolio managers. (See charts.)
Consequently, cross-border bond holdings have elevated enormously. What issues listed below are modifications in gross, not web, holdings. The latter are related to long-term sustainability of macroeconomic patterns of saving and spending. The previous are extra related to monetary stability, as a result of they drive (and are pushed by) modifications in monetary leverage, notably cross-border leverage. Furthermore, notes Shin, “the biggest will increase in portfolio holdings have been between superior economies, particularly between the US and Europe”. The rising economies are comparatively much less concerned on this lending.
How then does this new cross-border monetary system work? It has two elementary traits: the main roles of overseas forex swaps and non-bank monetary intermediaries.
The most important a part of this cross-border lending consists of the acquisition of greenback bonds, significantly US Treasuries. The overseas establishments shopping for these bonds, corresponding to pension funds, insurance coverage firms and hedge funds, find yourself with a greenback asset and a home forex legal responsibility. Forex hedging is important. The banking sector performs a key function, by enabling the marketplace for overseas trade swaps, which offer these hedges. Furthermore, a foreign exchange swap is a “collateralised borrowing operation”. But these don’t seem on steadiness sheets.
In accordance with the BIS, excellent foreign exchange swaps (together with forwards and forex swaps) reached $111tn on the finish of 2024, with foreign exchange swaps and forwards accounting for some two-thirds of that quantity. That is vastly greater than cross-border financial institution claims ($40tn) and worldwide bonds ($29tn). Furthermore, the market’s largest and fastest-growing half consists of contracts with non-dealer establishments. Lastly, some 90 per cent of foreign exchange swaps have the greenback on one aspect of the transaction and over three-quarters have a maturity of lower than one 12 months.
Because the BIS notes, this extremely non-transparent set of cross-border funding preparations additionally impacts the transmission of financial coverage. One of many propositions it makes is that the higher function of non-bank monetary intermediaries, notably hedge funds “could have contributed to extra correlated monetary situations throughout nations”. A few of that is fairly delicate. Given the large-scale overseas possession of US bonds, for instance, situations within the homeowners’ house markets may be transmitted to the US. Once more, trade fee actions that have an effect on the greenback worth of holdings of rising market money owed can set off changes of their home costs.
What are the dangers on this new system of finance? As has been famous, banks are lively available in the market for foreign exchange swaps. Additionally they present a lot of the repo financing for hedge funds speculating actively within the bond market. Furthermore, in keeping with the BIS, over 70 per cent of the bilateral repo financing from banks is at zero haircut. Consequently, lenders have little or no management over the leverage of the hedge funds lively in these markets. Not least, non-US banks are lively in offering greenback funding for corporations engaged in these markets.
What does all this suggest? Effectively, we now have tightly built-in monetary methods, particularly amongst high-income nations, even because the nations are shifting aside, politically and by way of their commerce relations. Furthermore, a lot of the funding is in {dollars} on comparatively brief maturities. It’s straightforward to think about situations by which funding dries up, maybe in response to giant actions in bond yields or another shock. As occurred within the GFC and the pandemic, the Federal Reserve must step in as lender of final resort, each instantly and by way of swap traces to different central banks, notably these in Europe. We assume that the Fed would certainly come to the rescue. However can that be taken with no consideration, particularly after Jay Powell is changed subsequent 12 months?
The system the BIS elucidates has a lot of the fragility of conventional banking, however even much less transparency. We’ve got an unlimited variety of unregulated companies taking extremely leveraged positions, funded on a short-term foundation, to spend money on long-term property whose market values could fluctuate considerably even when their capital values are in the end secure. This technique calls for an lively lender of final resort and a willingness to maintain deep worldwide co-operation in a disaster. It ought to work. However will it?
