No nation is an island – when it comes to economics at the least, if not geography. Commerce and capital hyperlink all of the economies of the world. Relative to GDP, the UK has extra overseas belongings and liabilities than every other massive financial system. These exterior liabilities – UK belongings owned by abroad buyers – might lead to vulnerabilities which may trigger main disruption to the financial system and monetary system in a stress. The excellent news for us is that the UK’s non-public sector exterior vulnerabilities have shrunk materially because the international monetary disaster (GFC) of 2008, though the general public sector’s vulnerabilities have grown. This submit explores how the UK’s steadiness sheet has modified because the GFC and what this implies for UK monetary stability.
The UK is among the most financially open economies on the earth. As a result of its position as a global monetary centre, it has exterior liabilities of over 550% of GDP, considerably larger than different G7 economies (Chart 1). The dimensions of those liabilities implies that the behaviour of overseas buyers, and their perceptions of the UK’s macroeconomic coverage framework and its long-term progress prospects, can have a fabric impression on UK monetary situations. On the excessive, a very massive and fast fall in overseas investor demand may trigger or amplify monetary crises by making refinancing of exterior liabilities tougher.

What makes an exterior steadiness sheet dangerous?
The construction of a rustic’s exterior steadiness sheet can have a big impact on its monetary fragility. The general internet place, and the composition of the belongings and liabilities underlying that internet place, are each vital drivers of dangers. For instance, the dangers related to short-term wholesale deposits are better than these related to long-term investments in bonds. Which means that vulnerabilities can construct throughout the elements of a rustic’s liabilities even when, total, they’re balanced with its belongings. For instance, UK banks had massive buyer funding gaps (extra loans than deposits) within the run-up to the GFC with a reliance on short-term wholesale funding to develop lending. A big a part of this funding got here from overseas. Worries concerning the well being of the UK banking sector throughout the GFC meant overseas suppliers of this funding didn’t rollover these funds, aggravating the liquidity stress for banks and the credit score crunch for family and company debtors.
Foreign money mismatches throughout the asset-liability mixture of a rustic’s exterior steadiness sheet may amplify short-term liquidity crises. Quite a few earlier creating financial system crises have been characterised by the lack of both the federal government or non-public sector to rollover short-term FX (overseas trade) debt. And in 2008, UK banks have been susceptible as a result of short-term FX liabilities exceeded their short-term FX belongings. Rolling over these liabilities grew to become tough as short-term greenback borrowing grew to become significantly scarce, which was solely alleviated by entry to Fed greenback swap strains. This threat was not seen when specializing in their total internet asset-liability place in FX, which was near steadiness.
Personal sector vulnerabilities have declined…
The dimensions of the UK non-public sector’s exterior vulnerabilities have declined materially because the GFC. A lot of this displays de-risking throughout the banking sector and stronger liquidity regulation. Wanting on the internet worldwide funding positions (Chart 2) permits us to measure the distinction between the UK’s exterior inventory of belongings and liabilities, which acts as an indicator for sustainable ranges of nationwide borrowing. As you’ll be able to see within the Chart, the important thing change within the debt and fairness positions because the mid-noughties is the big decline in foreign money and deposit liabilities, broadly akin to wholesale funding, that sometimes reside within the banking system. The legal responsibility place for this side of the UK’s exterior steadiness sheet is at its second lowest stage as a share of GDP in over 20 years. This significantly reduces the danger of exterior vulnerabilities throughout the banking sector impacting monetary stability within the occasion of a stress.
…and its mixture of belongings and liabilities offers advantages
The combination of the non-public sectors’ exterior belongings and liabilities can create dangers within the occasion of a change in overseas investor urge for food, however it additionally offers it with advantages more often than not. The non-public sector is lengthy on fairness and long-term debt. Per this, on common, the funding earnings and capital features on its comparatively dangerous or larger curiosity belongings have exceeded that on its comparatively secure or decrease curiosity liabilities. In impact, the online returns on abroad investments permit the UK to spend greater than its home earnings (run a present account deficit) with out changing into a internet debtor.

Public sector liabilities have elevated
In distinction to the non-public sector, UK authorities exterior liabilities have elevated because the GFC (Chart 3). The federal government has at all times had a internet exterior legal responsibility place as overseas buyers have at all times owned some authorities debt. This has elevated as a share of GDP materially because the GFC as each the dimensions of presidency debt and the share owned by overseas buyers have grown. This legal responsibility place is especially accounted for by long-term debt, which reduces the fast refinancing threat. However shocks to the credibility of UK establishments can nonetheless result in downward stress on all UK asset costs, and upward stress on risk-free charges, as overseas buyers are more likely to be significantly delicate to UK-specific dangers.

In abstract, the composition of the UK’s exterior steadiness sheet has modified fairly considerably because the GFC. A very massive and fast fall in overseas investor demand for UK belongings may trigger or amplify monetary crises by making refinancing of exterior liabilities tougher, however that threat seems low at current. As talked about, previously these dangers tended to be significantly acute for shorter period exterior liabilities. These refinancing dangers have been mitigated by the discount within the measurement of those shorter period ‘different funding’ liabilities and the improved resilience of the UK banking sector over the previous 15 years. This was partly as a result of improvement of a regulatory framework that, for instance, required monetary establishments with a better publicity to those dangers to carry bigger buffers of liquid belongings.
